Product Specs

• Material: Single-piece billet steel
• Fitment: Designed for the 40mm diameter early-style crankshafts
• Compatibility: Volvo B18 and B20 engines
• Adaptability: Later-style crankshafts can be machined down to accept this 40mm unit

Why Choose This Pulley?

• One-Piece Design: Unlike original two-piece pulleys with rubber dampeners, this billet unit cannot separate or perish under high-RPM stress.
• Extreme Strength: Manufactured from solid steel to withstand the rigours of racing and high-performance road use.
• Precision Timing: Features clear, accurate timing marks that won't shift over time, ensuring your ignition tuning remains spot-on.
• Compact & Durable: Resists the harmonic vibrations that can cause standard cast pulleys to crack or fail

Technical Note: This pulley is a direct fit for early crankshafts. If you are building a later B20 engine, simply have your machine shop turn the crankshaft nose down to 40mm to take advantage of this superior billet design
