These Chevy LS Swap Engine Mount Plates line up perfectly with the factory mounting pattern on all Chevy LS-series engines. Designed for fabricators building custom chassis, engine swaps, or off-road vehicles, these plates allow you to weld DOM tubing or custom brackets directly to the engine mounts—giving you full control over engine placement, angle, and position.

Precision laser cut from 1/4" high-strength plate steel, these mounts provide consistent accuracy and a weld-ready surface. This is the same style of mount used in our own Wide Open Design rigs for race vehicles, rock bouncers, and custom LS-powered builds.

Tech Insight

Unlike bolt-on swap mounts, these universal LS plates give fabricators total control. By welding tubing or boxed plates to the mount, you can tailor engine height, fore/aft position, and angle to your drivetrain setup. Precision laser cutting ensures that bolt hole alignment is perfect every time, preventing stress on the block and ensuring clean installation.
