VCS Progressive Spring kit

McPappy Racing is proud to release our new VCS progressive spring kit. The "variable pitch" design has 3 coils on one end which are designed to coil bind under 1/4" of compression travel. This allows the springs to be soft at first and rapidly increase in stiffness. Side shocks benefit by allowing the pod to be smooth and soft near the neutral resting position yet get progressively stiffer as the chassis rolls.  Likewise, if you use a small VCS shock for your center shock, the soft action handles the bumps nicely while getting stiff right before the chassis bottoms out. 

We offer traditional or precision ground flat ends. The ground flat ends lets the springs apply pressure slightly straighter and helps to keep it from rubbing on the shock body.
The kit included 8 pairs of springs. 5 lbs through 12 lbs in 1 pound increments.  You will receive a pair of 5, 6, 7, 8, 9, 10, 11, and 12 pound springs.  Approximate dimmensions are 1.20"L x  .048" OD.
