GPI Low Lift LS Camshaft - LLT4 (4.8L / 5.3L / 6.0L / 6.2L) - LLT4
High-Impact Low Lift Camshaft for Performance Trucks & Hot Rods
The GPI LLT4 is built for LS enthusiasts who want a rowdy, aggressive-sounding camshaft with strong midrange and top-end power while staying within low-lift valvetrain limits. Designed for 4.8L, 5.3L, 6.0L, and 6.2L truck engines, the LLT4 offers a big-cam idle and a usable RPM range beginning around 3,250 RPM, making it ideal for street/strip setups and hot rod builds.
This cam shines in stock bottom-end engines, especially when paired with high-flow intake/exhaust and deeper rear axle gearing.
Note: A higher stall converter and long-tube headers are required.

The LLT3, LLT4, and LLT5 make up GPI's Low Lift Performance cam lineup - designed for factory-style valvetrain durability while delivering the sound and performance of a traditional high-lift cam. These cams cover everything from mild hot rods to aggressive street builds.

FAQs
Does the LLT4 require a stall converter?
Yes. A higher stall speed (at least 3,000+) is required due to the cam's elevated operating range.
Can I run the LLT4 on a stock bottom end?
Yes - this cam is designed for stock long blocks and performs even better with upgraded intake, exhaust, and gears.
