Fits RB26DETT engines configured for 2.8L displacements.

The HKS RB26DETT 2.8L STEP ZERO Forged Piston Kit is engineered for high-performance engine builds where factory cast internals reach their mechanical limits. Designed specifically for 2.8L stroker applications, these 86.5mm bore pistons provide the structural integrity and thermal stability required for increased cylinder pressures and high-boost environments.

Each piston is forged from high-strength alloys and machined to exacting tolerances to ensure consistent ring sealing and predictable thermal expansion. This STEP ZERO kit is an essential foundation for tuners looking to improve the durability of their RB-series bottom end without sacrificing the response of a 2.8L displacement.
