Evolution Valve Spring Retainers B16A - B18C1/5 1.6/1.8L VTEC

Honda B16a, B18 and B20 Valvetrain Kits

BLOX Racing retainers are CNC-machined from the highest quality titanium available on the market. These Ti retainers are machined to exact specifications and help reduce the overall weight of the valvetrain area. As a direct result of the reduced weight, RPM's are increased. Each retainer provides assurance from premature wear associated with high RPM's and mileage. Set includes 16-piece titanium retainers for VTEC and non-VTEC applications.

Skunk2 Titanium Retainers are manufactured using the latest 3D CAD (Computer Aided Design) and FEA (Finite Element Analysis) to ensure that each is optimized for strength as well as for reduced weight. Skunk2 engineers then test and prove their designs on the engine dyno as well as the race track. Once approved for manufacturing, only medical-grade titanium that’s been ultrasonically inspected and certified is used. Following CNC machining, each retainer is then individually inspected to ensure proper hole diameter, taper, and that each are free from machining defects to ensure proper installed valve spring heights and pressures. Finally, each Titanium Retainer is serialized for your protection, including valuable information, like material batch specifics as well as production and inspection dates.

All Supertech valve springs are made with premium Superclean Chrome Silicon Vanadium Steel alloy for higher performance & durability at high rpms. Using high quality steel alloy allso provides the added benefit of better structural memory for all of our springs. Our valve springs are computer designed to ensure that wire stress levels do not overpass the limits of stress defined in the diagrams of fatigue. We also utalize computer software that allows us to ensure that the harmonics are under control. This combined with our high quality steel alloy enables supertech valve springs to be more durable in extreme conditions, giving your performance racing engine a serious competitive advantage in both perforamnce and durablity. Supertech retainers are manufactured with high quality military certified Titanium alloy, and are CNC machined for a tight fit. Our high quality retainers are among the best in the industry.
