    Balancer

    Posted by Steve townsley on 24th May 2024

    Absolutely awesome for car tires, struggling a little on Ram capped 20 inch tires. Balancer will do it no question but getting them set is difficult with available hardware. Other than that amazing, factory reset no issue, calibration perfect.

    Balance Anything

    Posted by Alex F on 15th May 2024

    I have been using this balancer for almost 4 years now and have never had a customer come back for a bad balance. Once you learn how to do it right, you can balance anything. I've worked on 6-figure cars and gotten perfect balance on low profile 21", 22" - no problem. You don't need a $15,000 road force balancer to work on Alfa Romeo, Mercedes, Rivian, Tesla, etc. As long as you know the fundamentals and not to counter-balance, know how to read the tire dots, etc. I would buy another one of these in a heartbeat. Still going strong after hundreds and hundreds of tires.

    W-937-40

    Posted by Kerry Stark on 30th Apr 2024

    So far I really like this balancer. I wanted a balancer with a 40mm shaft and this one does. It runs smooth and the 110 volt motor can handle the wheels very well. My old balancer was 220 volts so I was hoping these 110 volt machines could handle the weight of some wheels and tires and this one does. The calibration process is easy to do. Im not a professional, just a car hobbyist, so I wont be abusing this balancer, but there is no doubt that this machine could also handle continuous use if it had to. Looking forward to using it more and more.

    WB-937-40 Wheel Balancer

    Posted by Kerry Stark on 11th Apr 2024

    I recently purchased and received my new WB-937-40 Wheel Balancer. These balancers are packaged very well. Everything is wrapped and secured inside the crate. It arrived with zero damage. The 937 balancer is very easy to operate. Its built solid and comes with the necessary manuals needed. I like the 40 mm wide shaft that so many of the other brands do not have. I also love the fact that Derek Weaver has posted videos on their website pertaining to the unpacking, operation, and calibration of these machines. The balancer came with a great assortment of accessories (cone, gauge, and locking nut handle) so everything is included to get started balancing wheels. I had a question about the calibration procedure so I sent an email to Derek Weaver and within hours I had a reply. I find that their customer service and support is excellent. All I can say is that so far I love this balancer and I also love Derek Weaver's excellent customer support. I would highly recommend a Derek Weaver balancer if you are in the market to need a balancer. Im just a home owner that has a car hobby and I love the fact that I can do all my own tires. This WB-937-40 will be a great garage tool for what I want to do. Hats off to Derek Weaver!!!! Kerry Stark Shamokin Dam, PA

    937-40 wheel balancer

    Posted by Lee Sawyer on 31st Aug 2023

    I went back and forth on this item. I was trying to find a used balancer to save some money. There were other brands out there that had issues, outdated and were even more expensive. After speaking with Weaver multiple times I was very pleased with how great the customer service was when I had not even bought anything yet. Everything was answered. I pulled the trigger. The shipper was great as well as the whole process. I absolutely love this machine! It is well worth the money and I have no regrets. Machine is easy to use and has proven to be very accurate. Customer service after the sale is still top notch. Thank you for a great machine!

    Weaver Balancer

    Posted by Dave Logan on 6th Dec 2021

    I agree with other posters. You need a appointment for any tire service with poor results. I've wanted a tire balance machine for 30 years. Ended up buying the tire mounting machine too.

    Nice balancer

    Posted by Anthony Santana on 17th Jun 2021

    Extremely accurate I love it. It did take almost a month and a half to get but that was ok Dum (dumb covid) . It should save me a lot of money, I did all large tires and some small tires for a living 35 years. This machine is the same as other brands but this is the best price! Can't go wrong with it.

    Great Machine

    Posted by HERB ANDERSON on 5th Apr 2021

    Simple to setup and use. Balanced the summer tires on my wife's car using stick-on weights and also did my 3/4 ton pickup using standard hammer on weights. Both worked well and drive nice and smooth down the interstate. Great product. Will be back in the future to upgrade my old tire changing machine.

    Weaver 937-40 balancer

    Posted by Bryan on 28th Aug 2020

    Great balancer for the money. Watched the calibration video on their website and followed along to calibrate the balancer before use. It was easy to set up and start balancing. I’m a few dozen tires in now with no issues. The only thing I wish this balancer could do is balance larger truck tires (11R 22.5’s). Otherwise it is a great balancer for the money!

    W-937 Good Value

    Posted by Gary on 18th Sep 2016

    I bought a Derek Weaver W-937 balancer to replace an older balancer. Nice machine, Excellent Tech support if you need it. Good value, takes up very little space. I did have a problem but it ended up being the wheel. Balanced 4 more alloy wheels today, works perfect.

    simple, works

    Posted by Unknown on 14th Sep 2016

    Does what it is supposed to. Easy to operate, does a good job, tires run smooth. Instruction manual poor. Just watch the videos. Especially the calibration. I like not having a hood, simple. This is used on a farm, lots of vehicles, kids cars etc.

    Excellent Value

    Posted by Mike on 19th Jan 2016

    I had my balancer held at the local freight terminal. Pickup was easy and convenient. Set up took just few minutes. I have tried it on a variety of wheel styles and it it easy to set up and use. Perfect for my race car tires and all my street vehicles.

    Works like a champ!

    Posted by Jeff on 22nd May 2014

    My balancer works very well, hopefully i can get years of worry free use out of it, my only complaint is takes longer to come to a stop,might be just me being used to my old balancer, but other than that, i really like it, so far so good!

    Fantastic price, and works great

    Posted by Steve Kotalik on 25th Dec 2013

    I'm very pleased with how this balances wheels. I've done 20 so far. I did the calibration as instructed, and found it was still good from the factory, and shipping around the world, and then to me, so I'm pleased with what I believe to indicate a good design that is immune to vibration shock. One issue is the quality of the instruction manual. The printing of the manual in gray scale leaves it confusing relative to the button press operations. This is corrected by downloading a new manual, which has not been updated for the design changes. The other issue I can think of is the top needs to have a different design to hold tools and other items that are outside of the weight trays. Like special trays for self adhesive weights that come in strips, and utility knife tray, and other such tools that would be used outside of clipon weights. The hammer pliers tool included needs such a tray storage location vs just laying on top of weight trays. But for the price, it works flawlessly. As I'm a newbee to this type of machine, the many youtube videos were helpful.

    best bang for your buck, HANDS DOWN!!!!

    Posted by mark deschaine on 2nd Dec 2012

    Pretty much ready to use right out of the crate. Extremely accurate. Have used mine for 1- year, and no problems yet. Love balancing my own tires instead of paying $12-$15 per tire. Well worth the small investment.

Derek Weaver Company is proud to offer our high quality products with free shipping or warehouse pickup. Here's how it works...

PRODUCTS MARKED FREE SHIPPING

All Products on our website are offered with "Free Shipping". This means the freight charges are included in the price. Most of our products weighing less than 800-lbs. are offered with “Absolute Free Shipping” which means there are no extra fees. In this case you will notice the phrase “FREE SHIPPING! Includes Free Residential and Free Lift Gate Service!”, in the description of the products page. Absolute Free Shipping also means there are no additional fees for Liftgate Service or Residential Delivery. The only additional fee that you may incur would be if the address were changed during shipment which would incur a reconsignment fee by the freight carrier that we would only pass on if it were not our mistake.

For equipment over 800-lbs (most 2 & 4-Post lifts) there are some limitations for Free Shipping depending on weight and delivery location. In this case you will notice the phrase “Free Shipping To Over 85% of the USA - See Where It's Free” in the description of the products page. Most of the USA will require no additional fee. This applies to over 85% of the continental USA (lower 48 states). Free shipping does not apply to Alaska or Hawaii. Some parts of the country are affected by higher freight rates due to the combination of weight and delivery location which will require a small additional charge to cover the higher rate charged by the freight carriers. Our shopping cart will not calculate the difference (added fee), so we will contact you if this is the case. Rather than advertise the higher rates across the board we choose to show the lowest possible cost to most of the country. Like “Absolute Free Shipping” there will be no extra charge for lift gate or residential delivery. The following areas may have additional freight: North Western US, North Eastern US, Long Island, Western Colorado, the Dakotas, some parts of Florida & California and any area deemed a remote location by the freight company. Prior to ordering give us a call at 817-560-9510 or email and we can provide accurate information regarding Free Shipping or any additional charges.

FREIGHT CONSIDERATIONS

Shipping and delivery time given during the freight quote process is an estimated time of delivery given by the carrier. Choosing Liftgate Delivery may extend delivery times due to limited liftgate equipment at the delivering terminal. Meeting the delivery schedule is subject to the day the freight is shipped and the carrier’s ability to meet their schedule. Derek Weaver Co., Inc. does not guarantee that a carrier can meet their projected delivery time but we will provide you with the proper tracking information by email so you can follow the tracking time and arrange for special delivery needs with the carrier as needed. Any additional fees incurred as a result of consignee being unable to meet scheduled delivery time or cause for redelivery or reconsignment to a different location will be at consignee’s expense.

RESIDENTIAL DELIVERY:

Choosing Residential may extend the estimated delivery time due limited liftgate trucks at the delivering terminal, additional communication and handling by the freight company. Please keep this in mind when choosing residential delivery.

UNLOADING THE FREIGHT TRUCK:

Make sure you can unload the freight. A forklift or lifting equipment is required for items over 800-lbs. The trucking company is only responsible for delivery to your loading dock if delivered to a business address or curbside if a residential lift gate delivery. Lift gate service is available for some equipment and can assist in unloading 2 and 4-post lifts however you will still need a forklift. Liftgate capacity is typically 1000-lbs and cannot unload a 2 or 4-post lift on its own.

PICKUP AT YOUR LOCAL FREIGHT TERMINAL:

If you are unable to unload a truck, we have the option of letting you pick the freight up at the closest terminal to your location. When picking up at a terminal, the freight company will load your truck or trailer for you which is included in the freight cost. Call our office (1-817-560-9510) to determine the location of the closest terminal. If you require terminal pickup please place a note in the comment box requesting terminal pickup and we will contact you with the terminal location. Covered trailers or trailers with ramps are not acceptable as they prevent the forklift from getting the load into the trailer. They will not drive onto a ramped trailer. Please remove the ramps prior to picking up if possible.

All shipments must be inspected immediately upon receipt

IF AN ITEM HAS FREIGHT DAMAGE OR SCRATCHES

1) ACCEPTING AN ITEM WITH FREIGHT DAMAGE OR SCRATCHES.

Choose this option if you have minor dings and scratches or a part that needs replaced to make the unit satisfactory. Make note of the damage before you sign the freight bill. You will be responsible for filing the freight damage claim with the carrier. Derek Weaver Co, Inc. will provide any replacement parts or touch up paint needed should you choose this option and the carrier should provide for reimbursement. If you have any questions or need further assistance, please call our customer service department @ 1-817-560-9510

2) REFUSE THE DAMAGED ITEM.

Choose this option if the carrier has severely damaged the freight beyond your judgment of a simple repair. Derek Weaver Co, Inc. will file all freight claims. Get a copy of the freight bill from the truck driver and email it with a brief explanation of the situation to us. A replacement will be shipped as soon as we verify possession of the freight with the carrier.

SCHEDULING A WAREHOUSE PICKUP

If you would like to pick-up the item at one or our warehouses, please call ahead to make sure the item is in stock and schedule your pick-up. Picking up at our warehouse will save you in freight fees but will require sales tax to be collected. If you do not see a pickup price on our website for the product you are interested in you may call our office for more information.

In Texas we load Monday – Friday by appointment only.

In North Carolina we load Monday – Friday by appointment only.

All Two Post and Four Post Lifts require trailer for pickup. Be prepared for pick-up by understanding the item’s weight and dimensions and using the proper truck and/or trailer for hauling. We cannot load open or enclosed trailers with ramp gates. Our warehouse will load the item onto your vehicle and/or trailer but is not responsible for properly securing the load on your vehicle and you will need to make sure you have the proper straps and equipment for hauling. All items for local pick-up are charged state sales tax at the appropriate local rate. If you have any questions or need further assistance, please call our customer service department @ 1-817-560-9510
