RideTeach HD Universal Parallel 4-Link System

Boost your heavy-duty truck's performance with the HD 4-Link rear air suspension system, designed for superior ride quality, increased load capacity, and enhanced handling. Perfect for 3/4-ton and 1-ton trucks, this highly adaptable weld-on suspension kit seamlessly fits a wide range of vehicles, especially lowered trucks. Whether you're hauling trailers, cargo, or passengers, the HD 4-Link adjusts to varying weight loads—up to 7,000 lbs—offering a smooth ride unloaded and robust support when fully loaded, unlike traditional leaf spring suspensions.

Customize your setup with popular upgrades like Ridetech impact-forged monotube shocks, universal or vehicle-specific panhard bar kits, and a range of compressor and control systems tailored to your budget and performance needs.
