Crankshaft Pulley KIPA Aluminium for Chevy

Description

Product Overview

The KIPA crankshaft pulley is engineered for SB Chevrolet engines, combining a precision‑balanced design with premium billet aluminium construction. Measuring 6 9/16″ in diameter and 2″ tall, it features a 2 3/4″ bolt pattern and a 1 1/8″ center hole. Deep‑groove teeth are machined to prevent belt slip, delivering consistent power transfer to accessories such as the water pump, alternator, and AC compressor. The lightweight aluminium reduces rotating mass, enhancing engine response and efficiency.

Usage

Designed for SB Chevy models ranging from 265 to 400 cubic inches, this pulley fits engines equipped with a short water pump (SWP). It excels in daily driving, high‑performance builds, and restoration projects where reliable accessory drive is critical. Whether on the street or the track, the pulley maintains belt tension under high RPMs, making it suitable for both street‑legal and racing applications.

FAQ

Will this pulley fit a 350 Chevy with a standard water pump?

No. The KIPA pulley is designed for use with a short water pump (SWP) configuration. For standard water pump setups, a different pulley model is required.

What belt type is recommended?

n

We recommend a high‑quality serpentine belt that matches the OEM specifications for your engine. The deep‑groove design works well with both OEM and aftermarket belts.

Is the aluminium prone to cracking under high torque?

Billet aluminium used in this pulley offers excellent tensile strength and fatigue resistance, making it suitable for high‑torque applications without cracking.

Can I install this pulley myself?

Yes, with basic hand tools and a torque wrench. Follow the manufacturer’s torque specifications for the crankshaft bolt to ensure proper installation.

Does the pulley affect engine timing?

The pulley is dimensionally matched to OEM specifications, so it does not alter timing. Proper belt tensioning is essential for optimal performance.
