Porsche 928 (1978-1995) Rear Rocker Arm inc. Bush - PFR57-715BLK With the genuine OE part rarely available and over 400 to buy when it is, our new PFR57-715 Rocker Arm inc. Bush is a Black anodised replacement CNC-machined 6082-T6 grade aluminium arm and 95A durometer outer sleeve and bush, designed to replicate the function of the original rocker arm, providing toe-in during deceleration, thus eliminating lift-off oversteer. Our bracket is 3D machined and shaped to retain the important Rocker-Arm function of the original Porsche part but with updated, modern materials. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
