Perrin Subframe Lockdown Kit - STI 2004-2007 / WRX 2002-2007
Add drive train rigidity and precision to your Subaru with our PERRIN Performance Subframe & Diff Lock Down System.
The 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.
The PERRIN rear diff lock down (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.
