Raceseng - 1" Shock Top - Rear Upper Mount - Toyota 86 / Subaru BRZ
Toyota 86 / Subaru BRZ / Scion FR-S
Availability: In stock
The Raceseng Shock Tops provide a much needed 1 inch of extra rear shock travel. Each Shock Top extends the shock's shaft further up into the mount; allowing you to lower your car's stance without bouncing off your bump-stops as you drive.
The Shock Tops are made to work with a variety of aftermarket single height adjustable coilovers. No modifications necessary, they bolt right in! Please select the shock nut and shock bushing listed underneath your coilover.
Why do I need these 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 86/BRZ (ZN6/ZC6) chassis to gain the additional space needed to move the bump stop up and away from the shock body.
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.
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.
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.
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, contact us first, we will custom machine the parts necessary to make your coilovers work.
