Wiseco K696M965 Forged Piston Kit Nissan VQ37VHR 96.50mm +0.040 Over -3.5cc 10.5:1

The Wiseco K696M965 is a HD forged piston kit engineered specifically for the Nissan VQ37VHR 3.7L 24-valve V6 engine. Featuring a 96.50mm (+0.040 in. oversize) bore and a -3.5cc dome volume, this kit delivers a 10.5:1 compression ratio for naturally aspirated performance builds. Each kit is forged and machined in the USA from 2618 high-strength aluminum alloy for superior tensile strength and thermal fatigue resistance.

The pistons feature Wiseco's proprietary ArmorGlide® skirt coating, which reduces friction, resists seizure during break-in, and promotes quieter operation. The fully machined crown, precision ring grooves, and optimized valve pockets are designed for the VQ37VHR's multi-valve combustion chamber geometry.
