4G63 EVO 4-9 Integrated Main Cap Engine Block Brace

4G63 Cast iron EVO Integrated Main Cap Brace

We are proud to release this long-awaited masterpiece, an all in 1 main cap brace that now utilises everything we have learnt and about the standard OEM main cap system but this time we have incorporated the block brace and billet main caps itself in a one-piece unit and tied it all into the pan rail for the most effective outcome possible.

You have heard of or tried billet main caps, which do not offer block twist protection at all, they are also hard to pin down, they want to float.

The aftermarket bill at main cap is made of a very hard material, the harder the better you would think! WRONG, hard singular main caps do not absorb or disperse energy and shock, it bounces it straight back into the crank and con rods, and unless you are running alloy rods you will notice diminished bearing and rotating assembly life

An integrated main cap brace offers all the positives combines with none of the negatives. Benefits including energy and shock disbursement, much better twist protection, and no chance of main cap movement, even less chance of cracking the main cap.

This kit will require aftermarket ARP main cap studs for the Honda K series platform or at the on the listing we provide as an option.
