One of the obvious go-to for race builds and anything making higher HP is a set of ARP head studs. ARP themselves say they're working on developing a set, but who knows when they will be available, and at what price.

Meanwhile, we have a set of our own ARP2000 offerings that we have confirmed to fit perfectly! Regardless of if you're building a high HP N/A engine, a boosted setup, or even just a factory rebuild, you can't go wrong with ARP hardware!

Fits all UR engines, including the following:

1UR-FE (2010+ 4.6 in the Tundra, Sequoia, GX460, Land Cruiser Prado, and overseas Land Cruiser 4.6)
1UR-FSE (2008-2010 GS460, 2007-2017 LS460, and Crown Majesta 4.6)
2UR-FSE (2007-2017 LS600h)
2UR-GSE (2007-2017 IS-F, 2015+ GS-F, 2014+ RC-F, and 2017+ LC500. Does not include LC500h)
3UR-FE (2007+ Tundra, Sequoia, and Land Cruiser 5.7)
3UR-FBE (same as above, but for flex fuel vehicles)
