Guide to Hardness Selection (The Rating is based upon the Shore Hardness Scale)

As a general guide the rating of 60 Shore will imitate original rubber parts hardness for your car.

50, 60, 70 Shore - Typically subframe mountings, replacement of pu foam shock mounts etc. where low NVH (Noise Vibration & Hardness) is a priority and situations where compliance is desirable.

80, 88 Shore - Typically wishbone, radius rod, non coil over shock eye bushes

90 Shore - Typically leaf spring eyes or more heavily loaded wishbones & radius arms, trunnion bushes where replacing rubber

95 Shore - Typically intensely loaded coil over shock bushes, trunnion bushes where replacing nylon.
