Firestone F4179 Coil-Rite Air Helper Springs Rear Axle Kit

Firestone Coil-Rite air helper springs are designed for SUVs with coil spring suspensions and fit inside the current coil springs to create a variable spring rate. These springs help level your vehicle, improve braking and handling, and reduce tire wear. Constructed from durable polyurethane, they allow for adjustable spring rates that are far superior to those of standard coil springs.

Key Features:

• Supports 500-1000 lbs per set without changing overall vehicle weight capacity
• Variable spring rate provides higher spring rate in loaded conditions and slower spring rate in unloaded conditions
• Enables adjustment for varying loads and road conditions by inflating or deflating - spring performance can be altered as easily as inflating a tire
• Designed to work in temperatures between -40°F (-40°C) and 180°F (82°C)
• No-drill installation for most applications
• Requires minimum 5 psi at all times to prevent damage
• Adjusts easily with individual inflation valves for balanced load distribution

This kit is specifically designed to fit rear applications for the Honda Odyssey, Honda Pilot, and Acura MDX. The kit contains all necessary parts for a speedy, hassle-free installation with an average install time of about one to two hours. Coil-Rite air springs reduce your chances of bottoming out by softening the interplay between your SUV's frame and axle, and absorbing road shock.
