Clevite HX196KIT H-Series TriMetal Main Bearing Kit Extra Oil Clearance

The Clevite HX196KIT is an H-Series TriMetal main bearing kit designed for high-performance and competition engine applications. The HX designation indicates these bearings are built to H-Series specifications with an additional +.001" extra oil clearance over standard sizing — ideal for performance builds requiring increased clearance for high-volume oil systems or aggressive crankshaft tolerances.

Key Features:

• TriMetal Construction: Hardened steel back, cast copper-lead alloy substrate, and Babbitt overlay for superior strength, conformability, and embedability
• Extra Oil Clearance (+.001"): HX-suffix bearings provide an additional .001" clearance over standard H-Series for optimized oil film thickness in performance applications
• Medium Eccentricity & High Crush: Engineered for consistent seating and precise bore geometry under load
• Enlarged Chamfers: Greater crankshaft fillet clearance to accommodate oversized journal fillets common in performance and racing crankshafts
• No Flash Plating: Manufactured without flash plating for improved bearing seating and break-in
• Half-Groove (180°) Oil Grooves: Upper half grooved for optimal oil distribution to connecting rod journals

Originally developed for NASCAR-level competition, Clevite H-Series and HX-Series bearings are trusted across all forms of high-performance engine building — from street performance to full race applications. These bearings are especially well-suited to engines operating in the medium-to-high RPM range and crankshafts featuring oversized journal fillets.
