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.
Replacing your car rubber suspension bushes with Polyurethane Suspension Bushes will give you:
- Better road holding
- Constant steering geometry
- Increased tyre life
- More responsive steering
- Longer service life of suspension components

Size: 75 mm
This part suits arms with a 75mm diameter bush, for 65mm bushes please use PFF3-802GBLK. This is a replacement part that in our road series application is over 100% stiffer than the original rubber bush to withstand increased loading seen by this position on the car. PFF3-702GBLK provides +/- 0.5° caster offset that can be adjusted on the car for improved steering feel. Additional caster will also create additional negative camber on turn giving improved tyre contact with the road under heavy cornering. For a non-adjustable version of this bush please use PFF3-702BLK.
