Product Description

The Air Lift Performance 78670 rear kit is designed for enthusiasts who want the freedom to fine-tune their vehicle’s stance without compromising ride quality. With fully adjustable ride height, you can easily drop your car for that aggressive, show-ready look or raise it up for smooth and practical driving. The double bellows air springs provide excellent support and flexibility, while the included performance rear shocks help maintain stability and control-even when running lower ride heights. It’s a setup that delivers both style and function in one clean package.

Every component is built to last, from high-quality air springs to corrosion-resistant hardware and reliable fittings.

If you’re looking for a rear suspension solution that offers adjustability, comfort, and a clean, show-ready stance, the 78670 is a solid upgrade that brings your build to life.
