The days are long gone when you can bolt up a set of OE replacement shocks from the parts store and expect to have much success on the race track. Even in the entry level classes, setups have become more sophisticated and modern, rebuildable racing shocks are definitely part of the equation.

One of the keys to consistent shock operation is making sure no atmospheric air contaminants the nitrogen. This bleeder screw helps seal the system after all the air is out of the tube.

Fortunately, companies like QA1 are making high quality racing shocks affordable for racers on real-world budgets. QA1 also understands that the average Saturday night racer operates a lean and mean operation. There are no shock specialists and no money in the budget to be shipping shocks off every week to be dyno’ed and rebuilt. Instead, many of their shocks can be completely rebuilt in your shop or race trailer with a minimum of specialized tools.

In this video, QA1’s tech specialist Marshall Fegers explains the process for rebuilding their 26 Series monotube racing shock. The details may differ slightly for other styles or brands of shock absorber, but the process is always basically the same.
