Many people often think about shock absorbers and springs when looking at enhancing the performance of a suspension system. Very few realise the importance of bushes or the bump stop hidden away at the top of the shock piston yet they play such a key role in the drive and safety of a cars suspension. LK Performance are leading providers of Renault 21 bump stops as we understand the vital role they play. Often the only time bump stops are considered is during the installation of advanced springs and shocks but in actual fact they are a component that should be used much more, preventing damage and making the drive even smoother. There's nothing worse than driving along and hearing an annoying clunking sound each time you hit a bump and the Renault bump stops and bushes are designed to stop that annoying clunking sound for good.
