Porsche 911 Classic (1965-1967) Transmission Carrier Bush - PFR57-414 Made in our Dark Grey 80A durometer material to give the appearance of rubber but with the performance and longevity of polyurethane, reducing bush deflection by an impressive 50%. A small increase in NVH, usually at idle, should be expected when stiffening the connecting mount between the transmission and chassis. The harder the material used, the greater the NVH transmitted. Fits up to 1971 with 901 Transmission. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
