These springs are designed so that the lower end sits on the coil-over shock's adjustable spring seat and the upper end sits in the original spring pocket in the frame. This allows for the use of a longer and lighter spring for more stored energy, offering increased weight transfer. Greater durability is also achieved by locating the spring pressure in the frame and not on a single stud.R-Series front shocks are designed specifically for drag race applications. They offer simultaneous rebound and compression adjustment with the rebound valving being looser and the compression valving being firmer. A looser rebound in the front allows for better weight transfer to the rear when launching and a firmer compression keeps the front end from slamming back to the ground.
The threaded aluminum shock body allows for easy on-the-vehicle ride height adjustments.
