## Description

Incredible tools at an incredible price

## Features

- Vehicle Compatibility: These replacement air spring fits 2011-2022 Silverado Sierra 2500HD 3500HD, 2003-2009 Ram 2500 3500, 2011-2016 F250 F350; For Kit PN 2596/2299/2597/2550
- Air Spring: This is a replacement double convoluted air spring that fits into existing coil springs; NOT a complete kit with brackets and hardware itself
- Reduces Friction: Once your air springs are filled with the right amount of air, they help enhance your ride by reducing interleaf friction and absorbing road shock; It'll feel like you're riding on a cushion of air (because you are!)
- Ride Comfort: Beyond ride comfort, Ride-Rite air springs work to heighten your safety on the road; They help balance the pickup truck to support steering and braking responsiveness, reduce tire wear, and level headlight beams
- Reverses Sagging: Ride-Rite air springs stop leaf springs from irreversible sagging under constant load and lower your chances of bottoming out by softening frame-axle interaction

## Questions & Answers

**Q: What is the warranty on these bags?**
A: Ik don't now. I have Them for 5 jears and no problems.

**Q: would this work for raising the front of of a plow truck?**
A: I'm sure you could make it work to raise the front of a plow truck provided the truck has a solid front axle. The challenge you are up against though is you will damage the airbags from all of the weight constantly riding on the airbags. You are far better off sending your front leaf springs out to get them re arced and have a leaf added.

**Q: what size is the air hose and fitting ?**
A: round 18 cm; hihgt 16 cm; fit 1/4 inch; umder screwhole a little bit smaller than M10 bolt

**Q: I have an older 29 foot class A rv. My current air bags leak. Will these fit?**
A: I don't now.  I also do not now what an "older 29foot class A rv"is. The 6401 I repleased was an repleasment of an original 6401 mounted in my chevy van 2006.
