EMPI 82mm 4340 Counterweighted Stroker Crankshaft — Air-Cooled VW Type 1, 2276cc (00-8182-0)

If you're chasing real displacement out of a Type 1 case, the stroke is where it starts. This is EMPI's 82mm 4340 counter-weighted crankshaft (00-8182-0) on standard VW journals — the backbone of a 2276cc build when you pair it with 94mm cylinders. Forged 4340 steel, counterweighted for balance at the RPM a stroker actually sees.

Vehicle Fitment

• VW Beetle: Type 1 case machined for 82mm stroke
• VW Super Beetle: Type 1 case machined for 82mm stroke
• VW Bus: Type 1/Type 2 case machined for 82mm stroke
• VW Karmann Ghia: Type 1 case machined for 82mm stroke
• VW Type 3: Type 1 case machined for 82mm stroke
• VW Thing / 181: Type 1 case machined for 82mm stroke
• Buggy / Baja: Type 1 case machined for 82mm stroke

This is a build component, not a bolt-in. An 82mm crank swings a larger arc than stock and requires case clearancing at the cam tunnel, lifter bores, and case webbing, plus a matching 94mm cylinder bore. Not confirmed: stock un-clearanced cases, Type 4 engines.

Why Choose EMPI?

Forged 4340 steel and counterweighting give a stroker crank that stays balanced and durable at high RPM.
