The PPP Shift chassis is a great tuning car; usable on normal and high bite tracks by moving the front and rear suspensions assemblies. The standard setup requires holding the top slide nuts with a wrench which is difficult to get to, limiting track side tuning. Rocket Products (Ron Free) developed the fixture to hold the nuts on top making it easy to make track side changes easily from the bottom only, even just prior to your race. One wrench is all you need! Two styles available. The Standard model uses the nuts from the chassis kit as delivered from PPP (1/4" wrench; these nuts made need a small amount trimmed with a file to clear steering arms). The Small model uses nuts with outside diameter of 0.180" for reduced weight and additional clearance. You will supply the nuts, only the nut holder assemblies are supplied.
