Rod Bearing Set
(Pro Journal)
Some of the most common questions we get at LC engineering are: What is a Pro Journal? Is it better than a Toyota Journal? What bearings do I need? Well, let's try to clear the issue up a bit. During the R&D process on our crankshafts, LCE found that we could modify the rod journal and have the ability to use a Chevy style rod bearing, giving us better-bearing quality, selection, and availability. So anytime you see Pro Journal, it's referring to this modification. One important thing to remember is that if you run a Pro Journal crankshaft, then you need Pro Journal rod bearings and connecting rods. It also goes the other way; when running Pro Journal rods, you must run the Pro Journal crankshaft and rod bearings. So when you select your parts to be sure to match up the journal types.
Toyota Journal VS Pro Journal
Tech Note
Clevite 77 bearings are the ones to use in your high-performance engine because of their tri-metal construction, soft lead-alloy outer layer, copper-lead center, and steel backing. Clevite bearings withstand the friction, dirt, misalignment, wear, corrosion and heat that chew away bearing and journal life.
