You can quickly change the valve setting by simply compressing the shock fully and rotating the shaft until the indexing notch mates with the desired setting on the body.
It’s as simple as twist and click. As the car travels down the track, the front end will gradually descend to its ride height without unloading the rear tires which is a major cause of wheel spin. Our rear drag shocks are also adjustable in three ratios: 70/30, 60/40 and 50/50 Our rear shocks work in conjunction with our front shocks making the transition from initial launch to top end charge as smooth as possible.




Shock valving plays a very important role in the way your car will perform both during initial launch and throughout the quarter mile. The principle behind our shock absorber design is to allow the front end of the race car to rise rapidly upon initial launch, creating greater weight transfer and better traction to the rear tires.
Our rear drag shocks are also adjustable in three ratios: 70/30, 60/40 and 50/50 Competition engineering’s 3-way adjustable drag shocks are designed to allow the racer to dial-in the race car to meet changing track conditions. It’s as simple as twist and click. Replacement in competition Engineering P/N C2051. These ratios also represent the percentage of force required to compress and extend the shock unit.

Meets nhra requirements for cars running 1099 or quicker with modified firewalls and/or floorboards. Increases chassis rigidity for better reaction times. Tube ends are notched for better fit and easier installation.

Not to exceed vehicle gvwr gross vehicle weight rating. Seamless drawn-over-mandrel dom tubing decreases internal component wear, resulting in longer service life.
