We are in the process of machining up a whole batch of 4age Main Reinforcement Caps (aka ladder caps). Pretty similar to the Tomei ones but a better design and far less cost!
These will strengthen up your main caps when using RPM in the 9k range or high HP applications. Very simple mod which can save your engine for minimal cost.
Specs:
5 caps
4340 Billet Steel
Nitrided
Full radius on the top side to relief any stress
Fits with 4age ARP Main studs
$170 incl GST
Taking orders now, wont be ready until another 3-4 weeks.
