This Corvette A.I.R. Pump Pulley is a precise, restorationfocused replacement designed specifically for 19661967 C2 Corvettes. Built to mirror OEM dimensions, it preserves the original belt geometry and ensures the Air Injection Reactor (A.I.R.) system operates as the factory intended. If you’re restoring a mid‑60s Corvette or maintaining a periodcorrect engine bay, this pulley helps you keep the emissions components functioning and the underhood look authentic.

Why this pulley matters

The A.I.R. system relies on a beltdriven pump to inject air into the exhaust stream, lowering emissions and keeping the engine breathing evenly at idle and under load. An outofspec pulley can shift the pump’s speed, throw off belt alignment, and cause belt wear or intermittent operation of the A.I.R. system. This pulley is engineered to maintain the correct spacing and alignment between the crankshaft pulley, pump, and belt, so the air pump engages smoothly every time you start the engine.
