Premium Low-Lift Camshaft for Real-World Truck Performance
The GPI LLT1 Low Lift Camshaft is engineered specifically for LS-powered trucks that are used as trucks - Silverado, Sierra, Tahoe, Yukon, Avalanche, Suburban, hot rods, and street rods. Designed for everyday drivability with a noticeable bump in power, the LLT1 delivers excellent low-end torque, smooth idle quality, and exceptional valvetrain longevity without requiring additional modifications.
GPI's low-lift truck cam series is built for owners who want real gains without hurting towing capability, fuel efficiency, or reliability. If you want improved horsepower and torque across the entire curve with no downsides, the LLT1 is the perfect choice.
Low Lift Truck Camshaft Series Overview
