Spool Imports supplies GM, Chevrolet and Holden LS performance engine parts for street, circuit, drag and high-output engine builds. This LS engine hub brings together compatible products across the LS family, including forged pistons, conrods, crankshafts, bearings, gaskets, valvetrain components, fasteners and supporting engine hardware.

For complete bottom-end combinations, browse our engine rebuild kits and stroker kits. LS rebuild and stroker combinations should be selected around the exact block, bore, stroke, cylinder-head configuration, compression target and intended fuel rather than by capacity alone.

The LS family covers several generations and configurations, so confirm the actual engine and component dimensions before ordering. Differences in crank reluctor, rod length, piston design, head configuration and block specification can affect compatibility even where parts are commonly described simply as “LS”.

Browse the LS performance range below, or contact Spool Imports if you need help matching pistons, rods, crankshaft, bearings, gaskets and fasteners for an LS1, LS2, LS3, LS7 or related GM/Holden/Chevrolet combination.
