Whiteline – Engine Pitch Mount Bushing (Part No.W92832)

Engine Pitch Mount Bushing

from

$31.99
Subaru designed the pitch stop mount to assist in controlling the engine and drivetrain forward and aft twisting motion. The pitch stop is inherently soft due to the plastic body and high compliance rubber bushing design and was built for comfort and not responsiveness or feel. Whiteline’s Billet 6061-T6 aluminium pitch stop mounting is built to handle the demands of high torque and power output engines by limiting the amount of movement the engine and drivetrain will place upon the pitch stop. Utilising low compliance bushing technology this eliminates the slop, twisting and shudder found in the OEM rubber bushings allowing for a faster, positive, responsive feel of power delivery on and off the throttle.

Product Features:
  • Designed with the installer in mind by reducing the need of specialised skills, tools and equipment.
  • Whiteline’s latest technology synthetic elastomer formulation boasts resistance to oil, grease, ozone and weathering.
  • Designed with the installer in mind by reducing the need of specialised skills, tools and equipment.
  • Inserts are designed to work with the original factory bushing rather than replacing it.
