Upgrade your Nissan RB25 DOHC NEO (Solid lifter) valvetrain with Supertech valve spring kit. Each kit is matched as a complete valvetrain package — springs, retainers, locators, and locks — so installation is straightforward, and clearance issues are eliminated. Built to control valve motion at high RPM, reduce valve float, and support aggressive cam profiles. Compatible with most aftermarket and OEM camshafts within the rated lift range. Installation requires verifying the installed spring height with the included shims and confirming retainer-to-seal clearance. Recommended for any build running aggressive cams, increased RPM ceilings, or forced induction. Order direct from Supertech for fast shipping and expert technical support.
