The Lester Racing Laser Cut Fourth Wheel Replacement Guide Fins are the perfect center rail guide pegs for your Pinewood Derby racer. Just drill two #50 holes in the car body and screw the fin in place. One package contains 1 fin and 2 screws. Available in a curved design in either red, yellow or black.
When rules allow, using a guide peg to replace a front wheel will speed up the car by removing unnecessary weight from the front thus shortening the car′s center of gravity.
