Having pressure onthe shock piston, and therefore the shock shaft (rod) is central to its quick response design. But very high gas pressuresknown as rod pressure slow down the shock.So, gas pressure is your friend, but too much pressure is your enemy. Most shock builders run just enough gas pressure to prevent their shock from cavitating at high shaft speeds. Not uncommon to see 75-100 psi & higher.Two things can help reduce the rod pressure & still have no cavitationbase valves & remote canisters. The remote canister has its own piston & this reduces the pressure on the shock shaft, making the shock more responsive.Another is running a base valve in the bottom of the shock body. It is a valve that allows less pressure to be ran, with no cavitation, making the shock more responsive. Base Valves are an option on some of our ARS, Fox, JRI & Penske Shocks. Just talk to Ron Sutton about them. Our ARS DA, Fox DA & TA, JRI ST08 DA & TA, Penske 8300DA & 8760TA shocks, all come with remote canisters, so they have less rod pressure & are quicker responding as well.1126'
