XAT RACING Stainless Steel Intake and Exhaust Valve kit by Manley Standard and Oversize Sizing for 3UR and 1UR TOYOTA LEXUS 5.7 v8

XAT Racing has brought to market our Stainless Steel intake and exhaust valve kits for the TOYOTA/LEXUS 3UR and 1UR engines. If you're building a high horsepower engine, these valves are a must for dealing with the intense heat that a supercharger or turbo will be adding to the combustion process. Swirl polished heads, hardened tips, and chrome plated stems ensure years of durability and performance from these valves. We offer these kits in standard size or +.5mm oversized.

Standard Size kit will include 16x Intake valves at 38mm head size, 16x Exhaust valves at 32mm head size

Oversize kit will include  16x Intake valves at 38.5mm head size, 16x Exhaust valves at 32.5mm head size

These kits fit the TOYOTA/ LEXUS 5.7L 3UR  V8 engine, the TOYOTA/ LEXUS 4.6L 1UR-FE V8 engine found in the TUNDRA, SEQUOIA, GX460, LX570, LANDCRUISER 5.7 and 4.6L, and the LS460 Middle Eastern spec with the 1UR-FE engine.
