Master Refill Pack LS Cam Swap 346-9003

The Master Refill Pack LS Cam Swap 346-9003 from Straub Technologies Inc. is a comprehensive engine and accessory fastener kit engineered specifically for GM LS-series engines. This refill pack supplies the essential hardware needed to maintain, repair, or rebuild LS-platform engines with fasteners matched to factory specifications and torque requirements. The 21.6-pound refill contains a carefully curated selection of fasteners organized for quick access and accurate deployment during engine work.

LS-series engines demand precision fastening across multiple subsystems—from valve covers and cylinder heads to intake manifolds and accessory brackets. This refill pack addresses that requirement by including the correct fastener types, sizes, and quantities for common reassembly and repair scenarios. The organized packaging ensures technicians can locate the right fastener without delay, reducing assembly time and the risk of incorrect hardware installation. The compact dimensions (12 x 6.75 x 12.5 inches) allow the pack to fit within standard toolbox organization systems, making it practical for both shop and mobile service environments.

This fastener kit serves engine builders, performance shops, and independent technicians working on LS platforms across multiple applications—street vehicles, crate engine builds, racing engines, and restoration projects. Whether performing routine maintenance, addressing stripped threads, or executing a complete engine rebuild, having a dedicated LS fastener refill eliminates trips to fastener suppliers and reduces downtime. The Straub Master Pack system has established itself within the automotive fastening category as a solution that prioritizes organization and application-specific completeness over generic assortment packs.
