Description

Add drivetrain rigidity and precision to throttle input with the PERRIN Differential Lock Down System. The kit consists of 2 CNC-machined aluminum lock down plates and 4 urethane bushings that remove all movement from the rear differential under every driving condition - street, road racing, drifting or drag racing. Without it, the drivetrain twists under load, creating a "squishy" or "spongy" feel on initial acceleration; the PERRIN DLS locks the differential down for zero movement, so squat is reduced and power is delivered to the wheels with no delay.

  • Fits 2008-2014 Subaru WRX / WRX STI (rear differential)
  • 2 CNC-machined 6061-T6 aluminum lock down plates with black anodized finish
  • 4 high-durometer urethane bushings replace the soft factory bushings
  • Eliminates differential movement for immediate power delivery and reduced squat
  • Ideal for street, track, drift and drag use
  • Includes plates, bushings, warranty and instructions
  • Part #PSP-SUS-535
  • 5-year manufacturer warranty
