MAIN BEARINGS

Because many air-cooled engine cases require line-boring or have had the crankshaft journals ground during a rebuild, we offer a massive variety of sizes. We stock standard, oversized (for the case), and undersized (for the crank) bearings, including the specialized "thrust" bearings required for Type 1 and Type 4 engines. Our selection features industry-leading brands like Silverline and Mahle, ensuring you get the metallurgy and steel-backed durability your engine deserves.

Our Main Bearing Selection Features:

• Complete Size Availability: Standard, .020", .040", and .060" variations to accommodate line-bored cases and turned crankshafts.

• Vehicle Specific Fitment: Dedicated sets for VW Type 1 (Beetle/Ghia/Bus), Type 4 (914/Late Bus), and high-performance aftermarket cases.

• Performance Metallurgy: High-quality steel-backed aluminum or copper-lead alloys designed for superior heat dissipation and load-bearing capacity.

• Thrust Bearing Options: Available for standard and machined cases to ensure correct crankshaft end-play.

• Full Engine Coverage: We provide all the specialized bearings needed for the main journals, connecting rods, and camshafts.
