These Chevy S10 90/10 front drag shocks are performance driven. Soft rebound rate allows your front end to come up easy and allows better weight transfer.In addition, our 90/10 front shocks have dual rate compression valving.This keeps the front end from bottoming out on a hard landing. After your holeshot, the low speed compression is active and a softer valving allows the front end to setlle increasing your top end speed and reducing wander.All applications are closely evaluated for the best length, assuring that each vehicle will have sufficient travel for maximum traction. This is a commonly missed detail among other shock manufacturers.
