Manley 03-07 Nissan 350Z/Maxima 81.4mm Stroker 96.50mm +1.0mm Bore 8.5:1 Dish Piston Set w/ Rings

If you're building a performance engine for your 2003-2009 Nissan 350Z, 2003-2007 Maxima, or other compatible Infiniti and Nissan models, this Manley 81.4mm forged piston set is a solid choice. These pistons are designed to handle increased power and stress, making them ideal for stroker builds or high-performance applications where reliability is key. They feature a dish design that helps achieve an 8.5:1 compression ratio, which is often desirable for forced induction setups or when using aggressive camshafts.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their superior strength and ability to withstand high temperatures and pressures compared to cast aluminum. The set includes premium chrome moly wrist pins and features exacting standards for ring lands and grooves to ensure a good seal and maximize power output. The cam and barrel skirt profiles are carefully shaped to reduce friction and wear on the cylinder walls, contributing to both performance and longevity. Manley's unique manufacturing process ensures the ring grooves are perfectly square to the piston skirt, a detail that matters for consistent sealing under load.

This set is designed for a 96.50mm bore with a +1.0mm oversize, so be sure to check your cylinder wall measurements. It comes complete with rings, ready for installation by a professional engine builder. Please note that this part is not CARB approved and cannot be shipped to California.
