Gen III LS 4.8L / 5.3L Performance Parts
The Gen III LS 4.8L and 5.3L V8s (1999–2007) helped launch the LS legacy, offering reliable performance with an aluminum or iron block and output ranging from 270 to 320 hp. These small-displacement LS engines were workhorses in Silverado, Tahoe, Yukon, and Suburban models. Their simplicity and affordability make them ideal for swaps and builds. At Texas Speed & Performance, we offer cams, heads, and tuning packages to turn your Gen III LS into a high-revving performer.
