Perrin Performance - Subframe & Diff Lockdown - 04-07 Subaru WRX/STI
Add drivetrain rigidity and precision to throttle input to your Subaru with our PERRIN Diff Lock Down System.
Perrin Subframe Lockdown
The PERRIN Subframe Lockdown kit includes 2 urethane bushings, two metal sleeve washers and 2 bolts. They work together to solidify and lock the rear subframe in place eliminating all driveline slop and that annoying thud from first to second gear.
Perrin Diff Lockdown
The PERRIN Rear Diff Lockdown (DLS) consists of 4 urethane bushings that lock the differential by stiffening the front and rear mounts for zero movement under extreme conditions such as drag racing and road racing. This DLS removes the twisting movement from the rear differential which can cause a "squishy" or spongy feeling at the point of initial acceleration.
