Sea-Doo 4TEC Titanium Retainer Valve Spring Valve and Keeper Set (RXP-X, RXT-X, GTX)




Intake valves: Supertech primarily uses enhanced versions for EV8 (21-4n). Valves are fully CNC machined, with a hard chrome treatment, and hard tips. Stainless steel valves are widely used in dragsters and funny cars due to their high-temperature properties.

The CNC process eliminates any imperfections from the forging. They undergo a heat-treatment to ensure proper molecular integrity and uniform grain structure throughout the valve. The hard chrome plating reduces wear and provides optimum anti-friction performance. Excellent for high-performance or racing applications. stronger and lighter than stock valves, better heat resistance. The valve stem design near the head allows for more airflow. Improved rpm and hp. Part # SEAIVC-3860S

Exhaust valves: Supertech Inconel valves are used for exhaust valves in engines that reach very high temperatures and its use is growing with the application of turbos and superchargers. Valves also are swirl polished, have undercut stem, and a hardened tip. Part # SEAEVI-3160S Supertech keepers are included.

Dual Valve Springs: Our valve springs are made with premium Super Clean Chrome silicon Vanadium Steel alloy for higher performance and durability at high rpms and better memory. The valve springs are computer designed to ensure that wire stress levels do not overpass the limits of stress defined in the diagrams of fatigue for long durability under extreme conditions. Computer software also allows us to make sure that the harmonics are well under control limits.

Titanium Retainers: Aqua Sport Titanium valve retainer set for Sea-Doo RXP/RXT/GTI 4-TEC Supercharged. These retainers are manufactured with high-quality military certified Ti 17 and Ti 64 Titanium alloy and are CNC machined to precise dimensions. They are extremely strong and wear-resistant, all while being 40% lighter than their steel counterparts. Titanium retainer lightens the valve assembly and offers a higher RPM redline. Our materials are tested and certified for chemical purity, uniform grain microstructure, and superior mechanical properties, as well as sonically tested for imperfections.

Set Includes:12 dual valve springs + 12 titanium retainers + 6 intake valves + 6 exhaust valves + 12 pairs of keepers

For Sea-Doo 3-Cylinder 1503cc 4TEC motors.
