Chevy 5.3/5.7/LS1/LS6 Stroker

Record Setting Performance all season long! The Patented “X Groove” is a standard feature on our GSX, FX and Custom XR series pistons. Engine builders have worked for decades to optimize ring seal. Improved ring seal means more power and efficiency. Fuel wash down and break-in debris have always been the enemy of ring seal. DSS Racing developed and patented the “X Groove” system to reduce the effects caused by fuel wash down and wear debris. The X-shaped groove sweeps excess fuel and foreign matter into the oil drain-back holes on the down-stroke and into the side relief on the up-stroke. This sweeping effect keeps the debris from getting trapped between the piston skirt and the cylinder wall, where it would normally cause scoring damage. With exotic fuels, blowers, turbos, and NOS running at today’s power levels, ultra rich mixtures are required and commonplace. The X Groove’s sweeping action combats the damaging effects of these applications. Groove Does the “X Groove really work?

“ ” I have already used small block Chevy DSS pistons in high output nitrous applications where I have made a whole bunch of pulls at the 800 -850 HP. mark with nitrous and the pistons looked totally unscathed at the end of the tests. So just from my own experience here we can assume that the DSS piston is a tough player.” David Vizard, May 2008 Super Chevy Magazine / Mototech magazine. Over the years we have we have received many phone calls and E- Mails similar to these below: “We tore down my shop car’s motor, the Pistons rods and crank are MINT. You’d never think it has 6 seasons of abuse at 1000+ H.P. Check the pics attached. I still have to measure up everything, but I’m thinking about re-using the rotator and just changing heads. “ Thanks again Chris S.
