Upgrade Wrist Pins or Heavy Duty 1000whp pistons

The wrist pin used in our standard pistons has been tested successfully to 500whp. These upgraded wrist pins move the piston capability to 600whp. This is an upgrade to the wrist pins that come with our pistons and not available separately.

The ATS HD Forging is the ultimate evolution of the 3S/5S piston thus far. Built from a completely different forging these pistons have made 875whp and are rated to 1000whp. The HD Forged Pistons are only available with our Stage 3 wrist pins.
