Manley Valve Springs & Retainers Kit for RSX Type-S/Civic Si

Manley Valve Springs & Retainers Kit for RSX Type-S/Civic Si w/ Locks

Manley’s Pro Series Valve Springs and Retainers Kit with Locks is designed for those high-revving sport compact engines that demand superior performance. These kits are carefully matched to maximize your engine's potential, ensuring that each component complements the other. With its robust construction and precision engineering, this kit stands out as a significant upgrade for the Acura RSX Type S and Honda Civic Si models, covering years 2002 to 2011.

The heart of the kit, Manley's valve springs, are built using premium chrome silicon steel alloy. This choice of material is renowned for its strength and ability to withstand the rigors of performance tuning. Each spring undergoes stringent heat treatment and shot peening, processes that enhance its fatigue life and help maintain load consistency, ensuring reliable performance even under the most demanding conditions.

Their retainers are manufactured using heat-treated aerospace-grade titanium. Precision machined on dual spindle CNC equipment, they offer a jewel-like finish, contributing to not just aesthetics but also functional superiority. The reduced mass of these retainers allows your engine to reach higher RPMs without experiencing valve float—a crucial factor for maintaining engine reliability and performance.
