Stage 4 High Lift Truck Camshaft

The Texas Speed Stage 4 High Lift Truck Camshaft is a performance upgrade for 4.8L, 5.3L, 5.7L, and 6.0L LS truck engines. It features a 223/226 duration and a 111 LSA, resulting in a distinct, lopey idle that delivers significant power gains across the midrange and top end. Proprietary lobe profiles allow this cam to utilize standard beehive valve springs, making it a high-value performance solution for your engine build. Installation of this camshaft requires specific support components for proper operation. Compatible valve springs, such as PAC 1219 or TSP/PAC .660 dual valve springs, must be used. For vehicles equipped with an automatic transmission, an aftermarket 3000+ RPM stall converter is required. Additionally, the engine should feature a compression ratio of 9.5:1 or higher. Proper tuning is necessary to ensure optimal drivability for daily use in street, strip, or towing applications.
