TORQUE PLATE to suit any of the RB series engines. RB25, RB26, RB30 or RD28

Our PRP torque plate is almost essential when boring and honing your block.

Made from 6061 billet alloy especially designed and profiled to replicate head tensional dynamics.

 It’s a fact that bores pull out if round when you torque your head down onto your block, more so if you run aftermarket bolts with more than OEM tension, you should be using a torque plate for boring AND honing, you should run the same bolt you wish to use in your build with the same tension, and the head gasket in between.

 Once you finish machining you can pull the plate off and you may notice your bores are out of round, especially noticeable if you put a piston ring in it while setting ring gaps, a dial gauge will give you alarming results.

 Once you build your engine and torque your head, it’s all perfectly shaped and you WILL notice less premature piston and bore wear and of course less blow by.

 Your buying PRP so you are buying confidence backed by hundreds of hours of design research and years of testing.

Why You Should use a Torque Plate when Boring and Honing

Great replacement kit
Called around for quotes to get them replaced and everyone was quoting over $2k just for bellows. Figured I’d give it a try. The rubber is good quality and feels soft. Time will tell but this is an easy job if you’re mechanically inclined. Make sure you replace the plastic water pickup fitting while you’re at it. Found mine to be cracked on disassembly and had to wait for a new one. Should be a easy 3-4 hour job if your not doing the bearing and only doing bellows
