Part no GSA385 / GDA4011
Correct for Spitfire (all)
GT6 (non-rotoflex cars only)
Vitesse (non-rotoflex cars only)
To test if your Triumph would benefit from replacement shocks then it should not "bounce" more than one and a half times after a good shove downwards.
When fitting ensure the car is back on the ground before torquing up the shocks otherwise you run the risk of pinching the bushes which will subsequently wear out prematurely.
