With enthusiasts seeking to amp up the power in their Toyota Tundra pickups, Manley Performance has responded with a special valve-spring kit for the DOHC 5.7-liter 3UR-FE V-8 engine.

This engine also is employed in Toyota Sequoia, Land Cruiser and Lexus LX 570 applications.

Manley’s new kit (p/n 26205) features a set of 32 valve springs that are wound from an exceptionally pure steel alloy and engineered for use in conjunction with aftermarket camshafts that have lifts to .480 inch, according to the company.

The springs have a .990-inch OD and can be used with the factory spring seat. They’re rated at 75 pounds installed and 205 pounds when open.

Also included in the kit are lightweight titanium retainers. This allows the engine to achieve up to 10,000 rpm. The retainers are manufactured from heat-treated, aerospace-grade titanium and CNC-machined to exacting tolerances. They are designed for use with 5.5-millimeter stem valves and weigh only 7 grams apiece.
