Chevy V6 4.3L Hi-Tech Roller Timing Set 87-90

The COMP CAMS Chevy V6 4.3L Hi-Tech Roller Timing Set 87-90 is designed for Chevrolet V6 engine builders and performance enthusiasts who require reliable valve event control in second-generation small-block platforms. This timing set is essential for ensuring precise crankshaft-to-camshaft synchronization on 4.3L engines manufactured between 1987 and 1990, a time when factory components often experience wear and timing drift.

The Hi-Tech roller design incorporates a hardened roller chain that minimizes friction and eliminates the wear patterns typical of older nylon-gear systems found in 1987–1990 Chevy V6 engines. This roller timing set effectively distributes load across multiple contact points, reducing stretch and slippage that can lead to cam timing variance during acceleration and high-rpm operation. COMP CAMS' roller geometry maintains tight tolerances throughout the powerband, preventing timing creep that can negatively impact idle quality, throttle response, and fuel economy.

Whether you're restoring a pickup truck, van, or performance cruiser, this timing set includes all necessary sprockets and hardware, with precisely machined gear teeth designed to fit directly with stock 4.3L crankshaft and cam journals without modification. Installers performing cam upgrades, engine rebuilds, or timing chain replacements will find this product beneficial for both stock and modified applications.
