GM LS3 Billet Timing Set Adjustable

The GM LS3 Billet Timing Set Adjustable by COMP CAMS (model 7106CPG) is engineered for serious LS engine builders and high-performance enthusiasts who demand precision control over valve timing. This double-roller timing chain set replaces OEM timing components with a billet steel construction that withstands extreme RPM and boost pressures. If you're running a heavily modified LS3 or building a stroker engine with aggressive cam profiles, this adjustable timing set gives you the tuning capability that stock setups simply cannot deliver.

This timing set features a keyway adjustable design that allows you to dial in optimal cam timing independently of crank timing, a critical advantage when running custom or aftermarket camshafts. The double-roller chain geometry reduces friction and harmonics compared to single-roller designs, improving efficiency and reliability under sustained high-load conditions. Billet steel construction eliminates the brittleness issues associated with cast iron sprockets and provides superior durability for forced-induction applications, turbocharged builds, and naturally aspirated motors pushing past 8,000 RPM. The adjustability range lets you compensate for cam timing variations and fine-tune idle quality, low-end torque response, and peak power delivery without machining or engine-out adjustments.

Professional engine builders, bracket racers, and street performance builders rely on this kit when upgrading LS-series engines—especially LS3 applications where factory timing geometry conflicts with modern cam profiles. Installation requires basic timing set expertise and a degree wheel for optimal tuning; dyno verification of your specific configuration is recommended for maximum results. This is a complete kit compatible with all GM LS-series platforms, making it an essential upgrade for any build targeting reliability and repeatability beyond stock specifications.
