NOTE - The images below feature the 2" Shock Top version. The 1" version functions in the same manner except it provides 1" less of extra shock travel.

WHY DO I NEED THE SHOCK TOPS?
When you lower a car with single height adjustable coilovers, you inherently decrease the shock travel by moving the bump stop closer to the top of the shock body. We lower our car's ride height mostly to lower the center of gravity and improve handling. However, a coilover can't effectively function as a dampener if it has no shock travel. In any race application, bottoming out on the bump stop is extremely detrimental to your handling characteristics and ultimately leads to longer track times.
The Shock Tops use the architecture of the ZN6/ZC6 chassis to gain the additional space needed to move the bump stop up and away from the shock body.
HOW DO THE SHOCK TOPS WORK?
To increase the shock travel, we CNC machined our Shock Tops from a solid piece of billet aluminum. We press-fitted a spherical bearing into the topside of the Shock Top which accepts the shock shaft mounting hardware. The Shock Top's body provides the additional space to accept the bump stop; opening up the much needed shock travel.

The Raceseng Shock Tops image depict what they look like installed from inside the trunk. Notice how you can see the Shock Top protruding through the opening in the chassis. This was done to maximize the shock travel.

COIL SPRING PERCH
The underside of the Shock Top features a counter-bore which engages and locates the coil spring. The Shock Top will work with any 2 1/2", 2 1/4" or 60mm (I.D.) coil spring.
QUALITY USA SPHERICAL BEARINGS
We searched high and low for a USA made, high quality spherical bearing supplier. Our search ended with FK Bearings who has been manufacturing spherical bearings for the racing industry for over 40 years. FK specifically manufacturers our spherical bearings with a bearing race to ball fit that is made to take on the harshest road and race conditions. The spherical bearings also use a PTFE liner which is chemically bonded to the bearing race. We strive to use only high quality components in our products!
SHOCK NUT AND BUSHING
We machined the shock nut and bushing from stainless steel to provide the ultimate in corrosion resistant and longevity. The fitment of the shock nut and bushing is dependent upon the the coilover shock strut thread size and pitch.
CUSTOMIZABLE TO ANY COILOVER
The shock nut and bushing are made specifically for each type of coilover. If you do not see your coilover listed as an option, follow the steps below:
1 - Select the "Custom Shock Nut and Custom Shock Bushing" option in the checkout box above.
2 - Add the items to your cart and continue shopping or check out.
3 - Download the Shock Top Coilover Form below.
4 - Follow the instructions in the form and email or fax back to Raceseng.
5 - We will custom machine the parts necessary to make your coilovers work!
