XAT Manley Oversized Valves 3UR 1UR Toyota Lexus 5.7 4.6 V8 +1mm


Not rated yet

XAT is gearing up for some serious UR shenanigans! Taking the expertise we've gained from over a decade of UZ engine parts and development, we are now opening our services for the 1UR-FE and 3UR-FE truck engines from the Tundra, Sequoia, LX570, GX460, and Land Cruiser.


While this is not a part we normally stock, we are working on offering a complete set of 32 valves, 1 mm oversized intake (39mm) and 1mm oversized exhaust (33mm), to fit any FE head UR engine. We do not have confirmation of fitment for 2UR or 1UR-FSE yet.


That means these are made from the ground up specifically for the truck engines! Whether you're hot rodding a Toyota/Lexus truck, or swapping the engine into something quicker, we've got you covered. We do not use off the shelf parts for other engines and try to adapt them to work, these valves are made from the ground up specifically for this application.
