Stage 4 Low Lift Truck Camshaft 222/226 .550 111 LSA

The TSP Stage 4 Low Lift Truck Camshaft is engineered to deliver significant performance gains for a range of GM LS-based truck engines, including the 4.8, 5.3, 5.7, and 6.0L variants. This camshaft boasts a 222/226 duration with .550 lift and a 111 LSA, specifically designed to work with factory GM LS6 single beehive valve springs and stock pushrods, offering an affordable upgrade path. For 4.8L and 5.3L engines, this camshaft excels at providing enhanced mid to top-end power, characterized by a distinctly choppy and attention-grabbing idle. For 5.7L and 6.0L applications, it delivers impressive torque and midrange power, maintaining a noticeable idle while still ensuring good driveability. Both engine families benefit from the camshaft's ability to be easily daily driven once properly tuned. To optimize performance, an aftermarket stall converter with a 3000+ RPM rating is recommended for automatic transmissions. The recommended compression ratio for this camshaft is 9.5:1. The operating RPM range is specified as 1500-6500 RPM, with an advertised power increase of 68 horsepower and 23 ft-lbs of torque. This camshaft is not legal for sale or use in California.
