Hauling a trailer or loading up your cargo area can make the rear of your vehicle squat and throw off steering and braking. Firestone Coil-Rite Air Helper Springs fit inside your existing rear coil springs to add load-leveling support from at least 500 lbs up to 1,000 lbs. They help keep your ride height even, level your headlight beams, and maintain balanced handling when carrying or towing heavy loads.
Every load and road condition is different, so these air springs adjust to match. With 5 psi to 35 psi of manual air pressure adjustment using separate inflation valves, you can fine-tune each side for off-center loads and better stability. The added air cushion helps absorb road shock, prevent bottoming out, and improve steering response for a smoother, more controlled ride under load.
Coil-Rite air springs are made from durable, elastic polyurethane that holds up under heavy loading and rough conditions. The design works inside your existing coil springs without altering factory suspension geometry. The kit includes all necessary brackets, hardware, air lines, and valves for installation. Replacement springs are also available separately to keep the system performing for years.
Getting extra suspension support doesn’t require a shop visit. The Coil-Rite kit installs inside your rear coils with parts designed to fit your spring seats. Air line tubing routes easily to the bumper for quick access to the manual inflation valves, so you can fill or deflate the bags with basic tools whenever you need to adjust your setup.
The construction material of the fittings may vary.

Glad you gave them a shot, William! You also make a great point about checking for leaks before calling it a day. What have you been towing lately?

Gotta watch out for the kinks! I'm glad you caught it and were able to fix it, it sounds, pretty quickly :) Thanks for sharing the word of caution and experience :) When's the next trip with the new suspension and trailer?

After a year, the air bags have been superior in their performance. I have had no issues with them. Still running 20 psi in them when Im towing my trailer, deflating them to 10 psi when not. I see only slight rubbing signs on the bags from the coil springs, but hasnt effected the performance of the bags. Great product. Im very happy with the performance of the bags. Still a great product.
