The 8760PB-Drag is our best shock option for drag racing. The 8760 is a high quality piggy back triple adjustable shock that uses standard Penske parts. With separate high and low speed compression adjustability, and separate rebound adjustability, tuning your suspension for different track conditions and spring rates is easy. The separate compression adjustments are a must for Pro Stock, Pro Mod, and Top Sportsman teams looking to compete at the top levels. These separate adjustments make it easy to tune for the launch, track transitions, and down track. With less adjustable shocks, you have to sacrifice one end of the track to be optimum at the other end, with the 8760, you no longer need to do that. Stock, this shock comes with the air eyelet option, allowing for down track stability and control.

All aluminum parts make this shock durable and extremely light in weight.
Remote canister with larger nitrogen volume which makes the shock more repeatable at variable running temperatures
Revalveable using standard Penske piston and shim stacks, endless shim combinations make it possible to tune yours suspension for your exact feel
Three Way Adjustable

These go for $3750.00 on penskes website for the two rear shocks.
