PERRIN Performance PSP-SUS-525 Rear Subframe and Differential Lockdown Kit

The PERRIN Performance Rear Subframe and Differential Lockdown Kit is engineered to eliminate unwanted drivetrain movement and enhance your Subaru's performance under demanding driving conditions. This comprehensive system combines both subframe and differential lockdown components to deliver a more connected, precise driving experience.

Subframe Lockdown System:

The subframe lockdown portion includes 2 urethane bushings, two metal sleeve washers, and 2 bolts that work together to solidify and lock the rear subframe in place. This eliminates drivetrain slop and that annoying thud during quick gear changes, particularly the crucial first-to-second and second-to-third shifts.

Differential Lockdown System:

The differential lockdown consists of 2 CNC-machined aluminum plates and 4 high-durometer urethane bushings that completely remove movement from the rear differential under all conditions. By stiffening the front and rear differential mounts, this system locks down the differential for zero movement during performance street driving, road racing, drifting, or drag racing.

Key Features:

• Eliminates squishy or spongy feel during initial acceleration
• Reduces wheel hop and maintains rear-end stability under load
• Improves power transfer and chassis response
• Premium urethane bushings provide durability without excessive NVH
• Anodized aluminum construction for long-lasting performance
• Direct replacement for OEM rubber components
• Enhanced traction and more predictable handling

Installation requires basic hand tools and removal of rear differential and subframe components. This complete kit provides everything needed to firm up your Subaru's rear end and deliver the responsive, confidence-inspiring feel that enthusiasts demand.
