Pro-Crankshaft Sockets - GM LS Series

The Pro-Crankshaft Sockets – GM LS Series are precision-engineered tools designed for high-performance engine builders and shade-tree mechanics working on GM's legendary LS platform. Whether you're timing a freshly built 5.3L, 6.0L, or 7.0L block, or servicing the crankshaft on an existing LS engine, these sockets deliver the specialized access and secure grip required when working on the crankshaft nose. LS engine modifications demand accuracy, and improper socket fit can lead to rounded fasteners or stripped lugs—risks that these purpose-built sockets eliminate entirely.

Engineered by POWERHOUSE with meticulous dimensional tolerances, the Pro-Crankshaft Socket set matches the exact geometry of LS crankshaft hardware, providing a positive engagement that prevents cam-out even under the torque demands of final assembly or removal work. The socket's construction accounts for the tight engine bay constraints on LS-swapped vehicles and factory LS platforms alike, delivering both reach and leverage without unnecessary bulk. At 2 lbs and compact dimensions, these sockets integrate seamlessly into any shop kit while maintaining the structural integrity needed for reliable, repeatable fastener work on high-value engine builds.

This socket is essential for anyone planning an LS engine swap, performance tune, or complete engine refresh on vehicles ranging from fifth-generation Camaros to modern trucks and crossovers now running LS powerplants. Professional builders, restoration shops, and DIY enthusiasts undertaking serious LS work will find this tool indispensable for crankshaft bolt removal, timing cover work, and harmonic balancer installation—applications where OEM or universal sockets frequently slip or bind. Installation and use require standard 1/2" or 3/8" drive compatibility; verify your specific LS engine variant and fastener size before purchase to ensure perfect fit on your application.
