Package 1 – $2,200

($2,285 with C/O Kit)

Fronts & RR – 7200 series Rebound Adjustable shocks

Left Rear – 7200 series Compression Adjustable shock

This shock package contains 3 rebound adjustable shocks (L.F., R.F., & R.R. plus the left rear compression adjustable shock. All shocks are 7200 series base valve design. The shocks can be built with adjustable eyes or non-adjustable eyes that need to be removed for adjusting. Some Modified rules require removing the shock eye to adjust the shock. 

Left front adjustment allows you to fine tune the rebound to hold cross weight in the chassis which creates forward bite. Too much rebound dampening pulls the tire off the ground and makes the chassis push mid-corner to exit. 

Right front rebound controls the chassis attitude throughout the corner. Too much rebound hurts forward bite, and too little rebound unloads this corner creating a push condition. It’s important to have enough low speed rebound to hold attitude, but too much high speed rebound makes the chassis too rigid. The special right front piston allows the chassis to get down and turn on corner  entry and still have enough high speed compression to keep the chassis from slamming down.

 

 

Left rear shock is compression adjustable to provide enough range to hold the chassis up and make sure the left rear corner does not fall down and lose attitude. Too much compression makes the chassis too rigid which hurts traction. Too little compression will allow the chassis to fall too quick and lose rear steer. The base valve in this shock allows you to reduce the pressure and not make the chassis too rigid. 

Right rear shock is rebound adjustable which allows you to soften the rebound enough for heavy track conditions and stiffen the rebound for maximum traction. We lock in the compression dampening and adjust the gas pressure for heavy to dry/slick tracks. We adjust this shock more than any shock on the car to accommodate changing track conditions.

The Schrader valve can be removed and plugged if required by your racing series rules.

Fronts & LR – 7200 Series Mono Tube Non-Adjustable Steel Shock

Right Rear – 7200 Series Mono Tube E-Model Adjustable Steel Shock

 Fronts & LR – The 7200 Series shock is a large steel body mono-tube (gas) shock. This shock uses CNC machined aluminum internal parts designed for racing with no aftermarket parts.  This shock is designed for racers that are required to use a steel body.  This shock contains the latest base valve technology to provide low rod pressure which maximizes traction.  The advantage to the low pressure design is for when the racetrack becomes slick and tires lose their grip, the pressure is not increasing.  This provides more consistency from the first lap to the last lap by decreasing spring rate build up in your shock.  This shock comes with a Schrader valve to fine tune the gas pressure.  If your race series will not allow Schrader valves, the shock is available with pressure pre-set and cap in the port hole to make it legal. This is a Non-Adjustable shock. This shock accepts 2 1/2″ & 5″ O.D. Springs and is available in 6″, 7″, 8″ & 9″  shaft lengths.   RR – The 7200 Series shock is a large steel body mono-tube (gas) shock.  This shock uses CNC  machined aluminum internal parts designed for  racing with no aftermarket parts. This shock is  designed for racers that are required to use a steel  body. This shock contains the latest base valve   technology to provide low rod pressure which   maximizes traction.
