The HKS Cam Pulley (IN/EX) for the Toyota Corolla and MR2 with the 4A-GE engine from 1985 to 1991 is an adjustable cam gear designed to optimize engine timing. Constructed from anodized Duralumin with nickel-plated gear teeth, these cam pulleys allow precise tuning of intake and exhaust camshaft positions. This adjustment capability helps maximize engine performance, improve throttle response, and tailor power delivery across different RPM ranges. The high-quality materials and engineering ensure durability and consistent performance under various driving conditions, making it a reliable upgrade for enthusiasts seeking to enhance their engine's efficiency and power characteristics.

Designed specifically for 1985–1991 Toyota Corolla and MR2 models equipped with the 4A-GE engine, these cam pulleys are compatible with OEM or HKS camshafts. They serve as a performance upgrade or fine-tuning tool for street, track, or racing applications. Installation involves replacing the stock cam gears with these adjustable units, enabling precise timing adjustments to suit specific performance goals. The kit includes the cam pulleys and necessary hardware for installation. Suitable for enthusiasts aiming to optimize their engine's power band and overall performance, these cam pulleys provide a versatile solution for tuning and engine management.

Overview

The HKS Adjustable Cam Gears allow fine-tuning of the camshaft timing to maximize engine performance and tailor power characteristics for various driving conditions. Either with OEM or HKS Camshafts, adjustments can be made to tune an engine’s power band to the optimum RPM range for a particular application. HKS Cam Gears are made completely of anodized Duralumin with Nickle plated gear teeth except for applications with timing chains which utilize an aluminum slide with steel teeth. HKS engineers chose Duralumin as the core material for HKS Cam Gears because its lightweight properties decrease drag on the engine. Precise valve timing can be adjusted and set within the range of ± 20° along a Vernier scale of 2° intervals. Each interval index is laser-etched into the Duralumin and “A” (advance) and “R” (retard) directional markers are also laser-etched onto the cam gear face.
