Diagram Reference: 22 & 30

Kit Includes:
PFR5-4030
PFR5-4026 (Please select 1x or 2x from options)

PFR5-4026 is a replacement bush that features a built-in support washer, providing further stability of the diff under acceleration. Made using our signature Purple 80A durometer polyurethane and Black anodised 2011-T6 aluminium, to reduce drivetrain deflection and the potential for wheel-hop during hard launches.

PFR5-4030 is supplied complete with M14 bolt, thread locker and Powerflex keyring. The bracket comes on its own without bushes, so you can choose to use it with a variety of bush combinations. Single OE bush, Dual OE bushes, Single OE bush with single PU bush (1 x PFR5-4026) or Dual PU bushes (2 x PFR5-4026). We would recommend dual PU bushes ideally. If you wish to use it with a single OE bush with a single PU bush, then the PU bush would fit in the vacant right-hand mounting hole in the subframe.
