GPI Gen V LT 416 Lowered Compression Piston - 4.065? Bore - 901GWA
Forged 4.065? Pistons Engineered for 4.0? Stroke LT 415/416 Builds
The GPI 901GWA Gen V LT 416 Piston is purpose-built for 4.065? bore, 4.0? stroke engine combinations such as the GPI Boostrite 415/416 platforms. Developed as a variant of GPI's popular 900-series forged pistons, these units are precision-engineered to deliver lowered compression, exceptional strength, and reliable clearance for long-stroke Gen V LT builds.
Constructed from premium 2618 forged alloy and featuring .200? deep valve reliefs, the 901GWA piston is designed to withstand the extreme cylinder pressures of boosted or high-load applications. An altered compression height accommodates the 4? stroke, while a revised skirt profile provides proper counterweight clearance inside the crankcase.
Modeled After the 900 GWA Series - Strengthened for 416ci Applications
The 902/901 GWA pistons retain all the standout performance attributes of the 900 GWA line - dome geometry, ring land construction, and ring material - while incorporating key dimensional changes required for 4.065? × 4? rotating assemblies. The updated skirt and pin height ensure correct fitment and durability under heavy boost and high RPM.
