Product Description

The Ridetech 12313510 Front HQ Coil-Overs are designed for 1965-1979 Ford F-100 and 1975-1979 Ford F-150 2WD trucks equipped with the Ridetech front suspension/IFS system. The kit combines application-specific HQ Series coil-over shocks with matched Hyperco springs to provide adjustable ride height and improved suspension performance.

Each shock features a large 1.834-inch piston, heavy-duty 5/8-inch shaft, impact-forged body, and 24-position rebound adjustment. The included 10-inch Hyperco springs have a verified 750 lb/in rate, while the adjustable spring seats allow ride height and spring preload to be tuned after installation. Delrin spring washers help facilitate smooth spring adjustment.

The 12313510 is supplied as a pair and includes the coil springs, spring-retaining hardware, adjuster components, and bearing spacers identified in Ridetech's installation documentation. It is specifically intended for 2WD trucks using the Ridetech front suspension system and should not be applied to factory 4WD suspension configurations. Final ride-height, damping, and suspension-clearance checks should be completed after installation.
