Fits:
Porsche 911 1965-89
Porsche 912 1965-69

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.

Rear lower bush for Koni shock absorber. 
OEM Parn Number 91133352100

Fits:
Porsche 911 - 1965 to 1977
Porsche 930 turbo - 1975 to 1977

With many classic cars getting hold of original parts is becoming increasingly difficult with supply dwindling or worse, parts being discontinued altogether. 

The factory KONI rear shock absorbers are no exception. The rubber mounting bushes wear and perish, leading to vague handling or unwelcome knocks and clunks so we have added these Rear Shock Lower Bushes to the range. 

Made in our classic Grey 95A durometer material to retain that OE look, our bushes help to restore handling feel, with longevity backed by our Lifetime Warranty. They are also the perfect accompaniment to our PFR57-413 Rear Shock Upper Mounting Bush.
