Intake Exhaust Valve Spring Retainer for Sea-Doo RXT X 300 1630 2016-2023

Intake/Exhaust Valve Spring Retainer for Sea-Doo RXT X 300

This intake/exhaust valve spring retainer is a direct-fit valvetrain component for the Sea-Doo RXT X 300 1630, holding valve springs securely on the stem so the engine maintains compression and valve control at wide-open throttle.

Overview

This valve spring retainer is made for the Sea-Doo RXT X 300 1630 engine and locks the valve spring onto the valve stem so spring load stays consistent through the rev range. It helps prevent valve float and loss of compression under hard acceleration, making it a practical part for riders rebuilding or servicing the top end. Built for 2016 to 2023 RXT X 300 machines.

Good To Know

Q: Should retainers be replaced with the springs? A: Yes, retainers wear where they contact the valve stem and are best replaced alongside springs. Fresh retainers keep spring height correct and lower valve float risk.

Q: How many do I need for one head? A: Order one retainer for every valve, intake and exhaust combined. Check the valve count for your engine before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
