These are the RPM Blue Quick Adjust Spring Clips for 1/10 Traxxas, 1/10 Losi, & HPI Savage.
With RPMs clips, all the guesswork is removed and accuracy becomes as close to perfect as you can get! The set includes four spring guides that mount on top of each spring to prevent the spring from rubbing the shock body, and a full set (4 ea.) of four different thickness clips that snap around the shock body.
Vehicles with 8 shocks require two packages.
