Our take on the ARC Billet Rod 6252

The ARC 6252 is a +0.040-inch longer billet connecting rod for the Harbor Freight Predator 212cc engine, in both Hemi and Non-Hemi versions. It is machined from 7075-T651 aluminum and uses ARC's own bearing inserts and ARP rod bolts. The extra length lets a flat-top piston reach zero deck at top dead center on the stock crankshaft. Its standout feature is the forced oiling scoop dipper, which ARC says is the only one made for these engines, feeding oil to the rod journal. It suits engine builders doing a mild Predator 212 build who want stronger internals than the stock rod without changing the crank.

Questions and answers

What does the +0.040 length do?
It is 0.040 inch longer center-to-center than the stock rod, so a flat-top piston comes up to zero deck at top dead center with the stock crankshaft.
Does it fit both Hemi and Non-Hemi Predator 212?
Yes. ARC lists it for both versions of the Harbor Freight Predator 212cc.
What crank and piston does it need?
It uses the stock crankshaft, a 1.188-inch rod journal and a .709-inch (18mm) wrist pin, and is meant for a flat-top piston.
What bolts and bearings come with it?
It uses ARC's custom bearing inserts and ARP rod bolts manufactured specifically for ARC.
What is the oiling scoop dipper?
A dipper on the rod that scoops oil and forces it to the bearing journal. ARC says it is the only forced oiling scoop available for these engines.
Is it stronger than the stock rod?
It is billet 7075-T651 aluminum with ARP bolts, where the stock rod is a cast part, so it is built for higher load.
