ACL Nissan 4 K21 2065cc / K25 2488cc Forklift OHV 2v Engine Connecting Rod Bearing Set

200,000 psi tensile strength puts these ARP studs well above stock hardware. If you're rebuilding the engine in your 1984-1986 Nissan 200SX, especially if you're looking to get more out of that K21 2065cc or K25 2488cc engine, you'll want to pay close attention to the connecting rod bearings. These ACL bearings are a direct replacement, but they're built to handle more than stock.

ACL has been making engine bearings for a long time, and they know what it takes to make them last. These particular bearings are undersize by 0.010 inches, which is important if you've had your crankshaft ground down during a rebuild. They're made with a tri-metal construction that offers good strength and conformability, helping to cushion the crankshaft journal and reduce wear. This means you get a solid bearing that's ready for the demands of your engine.
