XAT Racing is now offering a UZ engine torque plate for those that want to properly hone the cylinders on their Toyota/Lexus V8s. It fits all UZ engines with factory sleeves. Any serious engine builder will tell you that you need a torque plate in order to provide a similar stress pattern on the block that it experiences with the head on the block. Some builders even go as far as putting an old head gasket between the block and plate, then go through a standard Toyota pattern for torquing down the bolts/studs. This is a precision machined torque plate, manufactured out of 2.0" (50.8mm) thick 6061 T6 aluminum (precision CNC'd by our own machine shop). Aluminum was chosen, as it best replicates stress and strain coefficients of expansion during torquing that the factory aluminum head does. It has an overbore that will allow for plenty of room for honing and boring as possible, so if you are building a setup with stock or slightly larger bore, you won't have an issue. It is shipped in a sturdy container for protection. These are quite possibly the only ones on the market anywhere, so instead of charging up to $800-plus for these units, we thought we would bring it to the market for a reasonable price!! You can expect one it to ship next day typically, as we have one on the shelf at all times! These are available for shipment outside the USA if required as well! Please email for a freight quote. A torque or honing plate is critical when doing the hone/bore process on any engine build, especially those that will be running a boosted setup and ARP head studs. Performance studs are typically torqued at much higher values than standard OEM studs, which causes a deflection in the cylinders if not using a torque plate.

Please note the $75 rental is for 1 week, which starts from the day you receive the plate. If you need it longer, we will prorate the charge out of the refund for each week after. You may be better off purchasing it outright if you end up needing it for more than a week or two.
