ACL Race Series Standard Rod Bearings for Ford V8 Engines

ACL 8B1442H-STD is a connecting-rod bearing set for the cataloged Ford 4.6L VIN W/X Romeo, 4.6L 3v VIN 8/H, 4.6L VIN 6,W,X Wind, 4.6L DOHC VIN H/R/V engine configurations. STD manufacturer size designation; verify the exact engine and assembled clearance.

Bearing Configuration

H identifies the ACL Race Series family. Match the complete suffix to the required clearance, shell width and locating features.

Engine Application

ACLs 2023 guide identifies the 8B1442H configuration for OE crankshafts and separately catalogs the narrowed 8B1442HN configuration for aftermarket-crank applications. Its technical table lists maximum shell lengths of 20.95 mm for H and 19.70 mm for HN. Match the actual crankshaft fillet, rod and edge-clearance requirements rather than assuming the two configurations are interchangeable.

The engine-family list identifies catalog applications, not universal vehicle fitment. Confirm the exact engine version, crankshaft, rods, block and bearing location. Vehicle names and photos do not replace dimensional verification.

Specifications

Quantity and Assembly Checks

Confirm the rod-bearing set contents and shell positions against the complete manufacturer number. The photo is representative of the part family.

Measure shaft journals, housing bores and assembled oil clearance using the engine builders specification. Check oil-hole alignment, groove placement and crankshaft fillet clearance before final assembly. Catalog standard dimensions must not be treated as the finished dimensions for a different repair size. ACL specifies that abrasive pads or paper must not be used on the bearing surface to alter oil clearance.
