McPappy Racing progressive VCS springs

McPappy Racing release the 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 a small VCS shock is used for the centre shock, the soft action handles the bumps nicely while getting stiff right before the chassis bottoms out. The springs are available with traditional or precision ground flat ends with the latter applying pressure slightly straighter and helping to keep it from rubbing on the shock body. The kit included 8 pairs of springs from 5 lbs through 12 lbs in 1 pound increments.
