Firestone Suspension® - Coil-Rite™ Rear Air Helper Spring Kit Installation Instructions

Warranty

Customers have counted on Firestone for over 75 years. There’s a reason for that. Actually there are three: Quality, Reliability and Service. Ride-Rite was the first and is the last manufacturer of air springs in the United States. Brand's quality is second to none. Firestone air spring products are the most reliable on the road with the warranty to back it up. And if you’ve got a question or a problem, from installation to maintenance to finding the right spring for your vehicle, we’re here to help.

FIRESTONE LIMITED LIFETIME AIR SPRING WARRANTY

Firestone Industrial Products Company LLC (“Firestone”) warrants that its Ride Rite Air Spring Assembly will perform according to the manufacturer’s specifications for as long as the vehicle on which the system was originally installed is owned by the original retail purchaser. This limited warranty does not include installation or other service charges for replacement.

Warranty Period:

The Air Spring is warranted for as long as the original purchaser owns the vehicle on which it was originally installed. The fasteners and upper and lower brackets which accompany the air spring are warranted for a period of twenty-four (24) months or 24,000 miles whichever occurs first. This warranty begins on the original retail delivery date.

What Is Covered:

Any implied warranties are limited in duration to the coverage period of this warranty (some states do not allow limitation on how long an implied warranty lasts so the above limitation may not apply to you). This Warranty runs in favor of the original retail purchaser when the Ride Rite Air Spring Assembly is used under normal operating conditions according to Firestone’s specifications and installed on the appropriate application. This warranty does not apply to Ride Rite Air Spring Assemblies that have been improperly applied, improperly installed, used in racing or off road applications or used for commercial purposes. In addition, the warranty will not apply to products which have not been maintained and serviced according to the instructions that accompany the air spring assembly. If it is determined that the Ride-Rite Air Spring assembly failed as a result of a manufacturing defect, Firestone will repair or replace, at its option, any product or components subject to this warranty. You should retain a copy of your contract with your installer and your receipt as proof of the date of installation. This warranty is non-transferable and is not assignable in any way.

The above limitation or exclusion may not apply to you. There are no warranties, express or implied, including implied warranty of merchantability and fitness which extend beyond this warranty.

Awesome Squat Booster.

Firestone Suspension® 4176 - Coil-Rite™ Rear Air Helper Spring Kit

Installed these on my 2014 Audi A6 tdi. I pull my work trailer everywhere with my car and my car always looked horribly squatted. I installed these helper springs in like 15 minutes per side using only a Jack, lug wrench, and a quarter inch drill bit. It leveled out my car with the trailer hooked up, with 35 psi in each. I hit a deer with that car and forgot to take off my hitch and helper springs, so now I have to buy new and do a fresh install on my 2013 Audi A6 3.0t. The springs are the same size as the Volkswagen counterpart vehicles, and they weigh around the same amount roughly. Bottom line, I would recommend them to anyone who would benefit from the advantages of helper springs, and I’m buying another set once I’m done writing this review.

Firestone® - Coil-Rite™ Rear Air Helper Spring Kit

This was the perfect solution to my problem. I was hauling a 150cc Motor Scooter on the back of my RAV4 and it was not a safe situation. I ordered these, the price and service were spot on, and then my dealer installed the 'air helpers. I am pleased to say they work perfectly and I can now safely haul my motor scooter without any steering issues. the 'airs helpers' inflate in seconds with a tire pump or in my case a simple small air compressor that plugs into the cigarette lighter.

Firestone® 4121 - Coil-Rite™ Rear Air Helper Spring Kit

These are great air bags, very well constructed and very easy installation. The nice thing was all the brackets are vehicle specific so took hardly no time to install.
