PROSPEED Forged 3UR Shortblock Package
In our quest to make more power in the 3UR, we ran into issues with the ever so common broken piston failure, even after finding ways to band aid the issue, we would still have failures. This all stems from the factory pistons having too tight of ring gap matched with pistons designed for NA with weak ring lands, past that failure point, the next weak link is the factory rods.
Our forged shortblock package tackles these issues by utilizing Manley billet connecting rods along with our proprietary low compression forged pistons with upgraded wrist pins. We combine this with the factory forged crankshaft, then we perform all machining and blue printing, then assemble it all together with the appropriate clearances for the increased power by our engine building partner Arrow Machine. This provides a solid shortblock good for 900+HP, allowing you to make the extra power you want without having to worry about stock engine failures.
