This Stage 1 LST kit is a solid choice for “cam-only” turbo setups where backpressure is unknown. It brings matched components for dependable results and proper valve control under boost. The kit includes lifters, a 58X 4‑pole timing set, pushrods, springs, retainers, locks, seats, and seals, built around a hydraulic roller profile for LS engines.
