Does your truck or SUV have some sag in the front end? Or would you like to give it a sportier, firmer feel? If your answer is yes, then you need to get SumoSprings coil spring boosters! Adding these boosters will take care of your front end sag, give you a sportier feel in the corners, or keep the rear end from sagging while towing or adding a heavy bumper.

The SumoSprings coil spring booster works by sliding between the turns of your factory coil springs and they work on both front or rear coils. When added to the front of your ride they will eliminate sag or front end dip and they reduce body roll while cornering. In rear coil applications, they keep your bed from sagging while towing or hauling heavy cargo. Made from a proprietary closed cell urethane material, these boosters progressively slow your spring compression to provide a comfortable ride.

You can have a professional install your new coil spring boosters or you can choose to add them yourself. There are no special tools, cutting, or drilling required. Most vehicles can have a set installed in less than 30 minutes. Once installed, you don't need to give them a second thought as all SumoSprings are 100% maintenance free!

When compared to other products designed to give you the same end result, it's clear that SumoSprings coil spring boosters come out on top! They are simple to install, require no maintenance, they're affordable, and they are made right here in Carpentiria California. Order a set for yourself & a friend, they'll definitely appreciate it!

SuperSprings™ neither assumes nor authorizes any vendor, retailer or other person or entity to assume for it any other obligation or liability in connection with this product or warranty.

What is Covered?

Subject to the terms, exclusions and limitations herein, SuperSprings International, Inc. Warrants to the initial retail or fleet purchaser only that its SumoSprings suspension stabilizer shall be free of defects in material and workmanship for two years. This limited warranty extends only to the initial retail or fleet purchaser with respect to use upon the vehicle the product is first installed. The term of this warranty shall be measured from the date of purchase. SuperSprings™ reserves the rights to: (a.) require claimant’s proof of purchase as a condition of this limited warranty, (b.) make future revisions to its limited warranty without prior notice. ALL OTHER EXPRESS OR IMPLIED WARRANTIES INCLUDING MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE ARE HEREBY DISCLAIMED.

What is Not Covered?

Remedy Limited to Repair / Replacement.

Upon inspection, your item will either be repaired or replaced with product or parts covered under this limited warranty. Customers requesting warranty consideration should first contact the independent distributor from whom you purchased your SumoSprings to obtain a Returned Goods Authorization number. All removal, shipping and installation costs are customer’s responsibility. If a replacement part is needed before yours can be returned, you must first purchase the replacement part. Then, if SuperSprings™ deems your part warrantable, you will be credited the purchase price. Your warrantor is SuperSprings International, Inc.

In consideration of the purchase price paid, neither SuperSprings International, Inc. or any independent SuperSprings™ distributor are responsible for any installation or removal costs, time loss, rental costs, or for any incidental, consequential, punitive or other damages you or third parties may incur in connection with any product purchased. Your exclusive remedy hereunder for covered parts is repair/replacement as described above. This Limited Warranty gives you specific rights. You may also have other rights that vary from state to state. For example, while all implied warranties are disclaimed herein, any implied warranty required by law is limited to the terms of Limited Warranty described above. Some states do not allow limitations of how long an implied warranty lasts and /or do not allow the exclusion or limitation of incidental or consequential damages, so the limitations and exclusions herein may not apply to you.
