Building an LS motor?
Don't forget this little but crucial piece!

This is the BTR (Brian Tooley Racing) camshaft thrust retainer plate kit, and it fits both Gen 3 and Gen 4 LS engines—think 4.8, 5.3, 6.0, 6.2, LS1, LS2, LS3, you name it.

It comes with the plate and all the bolts you need to lock your cam in place correctly.
The BTR part number is BTR89016-BOLTS, and it crosses over to the OEM number 12589016.

It's a brand new part made right here in the USA.
Even though it's a stock-style replacement, using a quality plate from BTR is a smart move to prevent cam walk and keep your valvetrain happy.
Whether you're doing a stock rebuild or a high-horsepower build, this kit is a solid, affordable upgrade in reliability.
