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.

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.

Pro Series XP Racing Valve Springs are engineered to handle the demands of extreme-lift camshafts operating at prolonged, high-rpm use at championship-level racing. Skunk2’s Pro Series XP Racing Valve Spring’s for the Honda’s K-series i-VTEC engines are simply the best on the market. Pro Series XP Racing Valve Springs have been tested at speeds exceeding 11,000 rpm on our engine dyno, street, and the race track. Our superior, Japanese-milled, super-clean chrome silicone wire is 100-percent eddy-current inspected prior to coiling. Next, they are heat-treated, shot-peened, and chemically polished for strength and durability. A special nitriding process concludes Skunk2’s rigorous manufacturing process. The end result is a lightweight valve spring that safely accommodates high-lift camshafts and features superior resistance to load loss, even under extreme operating conditions.
