GD Engine Swap Frame Rail Mounts
These mounts provide a simple, fabrication-friendly way to build custom LS engine mounts directly off the vehicle's frame rails.
The standard kit includes the bent frame rail brackets with the polyurethane bushing pockets already welded in place, along with the polyurethane bushings, sleeves, and mounting bolts. The brackets are supplied ready to fit and weld to your frame rails, giving you a solid chassis-side mounting point with polyurethane isolation.
For Gen 3 and Gen 4 LS engines, you can add the engine-side mounting components for $100. This option includes the unwelded LS block plates and mounting tubes, along with M10-1.5 × 25 mm bolts for attaching the plates to the engine.
Leaving the engine-side components unwelded allows the engine to be positioned where you want it before the tubes are fitted and welded to the mount plates.
Standard kit includes:
- Bent frame rail brackets with bushing pockets welded in place
- Polyurethane bushings
- Poly bushing sleeves
- Bushing mounting bolts
Optional Gen 3/4 LS Mount Components — +$100:
- Gen 3/4 LS engine mount plates
- Mounting tubes
- M10-1.5 × 25 mm engine mount bolts
- Plates and tubes supplied unwelded
The CAD and installation photos show how the frame-side brackets and optional LS components work together in a completed installation.
