Overview
The Firestone Ride-Rite Sport-Rite rear air helper spring kit, model 2304, is a leaf spring mount kit rated at 4,800 lbs of load leveling capacity per pair. Sport-Rite is the leaf spring mount member of the Ride-Rite line, and it uses double convoluted air bags.
Installation requires drilling, so mounting holes are part of the job. The kit is marked compatible with lift kits when spacers are used, and the compressor and gauges are sold separately.

Load leveling and ride height
An air helper spring works alongside the leaf spring, adding support when the vehicle carries weight or pulls a load. The bags do not change the spring rate on their own, so they are used to level ride height rather than to replace the leaf springs. Set the pressure to suit the load, and recheck it when the load changes.
Leaf spring work often involves the shackles, bushings and axle mounts, so inspect those parts when the helper springs go in. Worn bushings can shift the axle and wear the bags against the frame. Check bag condition after installation and look for rubbing, cracks and air leaks at the fittings. A regular pressure check helps catch slow leaks early.
- Inspect shackles and bushings during install
- Check bags for rubbing against the frame
- Check pressure before each heavy load
