Description

The GM LS FT Piston Set 4.005 Bore -3.2cc by Wiseco is designed for serious LS engine builders and high-performance mechanics who demand precision and durability in forced induction applications. This piston set is specifically engineered to withstand the extreme combustion pressures and thermal loads generated by superchargers and turbochargers in modern LS platforms.

Wiseco's expertise in forged aluminum piston manufacturing is evident in the FT designation, indicating these pistons are optimized for forced-induction duty with advanced dome geometry and reinforced pin bosses. The 4.005-inch bore specification, combined with the -3.2cc dish volume, provides optimal compression characteristics for boosted LS engines while accommodating intercooler piping and intake manifold configurations.

This piston set is ideal for LS1, LS2, LS3, and LS-based crate engine platforms, particularly those running boost levels between 8 and 12 psi. Wiseco's proprietary thermal treatment and precision manufacturing tolerances ensure each piston maintains consistent ring seal and minimal quench distance across all eight cylinders, making it a reliable choice for high-performance builds.
