Problem Solver

This Steel Series replacement boost valve & sleeve kit gives you a perfectly dialed in ratio slightly higher than the stock valve. This new valve helps eliminate all the problems associated with a worn out stock aluminum valve such as low line pressure, softer shifts and cross leaks. As with all Superior boost valves this valve is made out of 100% hardened steel & made in the USA.
