Arrived in good time,easy to install took 15 minutes not road tested them yet but I think they will be fine👍

Peter Chilton
Progressive front springs

Springs arrived quickly and looked great quality, equal lengths...believe me this is not always the case with other manufacturers. Springs fitted and I can certainly feel an improvement. Well worth the money.

Genuine & Reliable

Very upfront and genuine company. No problems, good quality products at the right price. I have already purchased rear shocks which work exceptionally well so now fitted front springs to complete the improvements.
