Already running M.O.R.E.'s JM200 or JM400 Bomb Proof motor mounts and now dropping in a Chevy LS? These block plates let you make the jump without starting over. Swap the block plates, keep the rest of your mounts, and the mounts are ready for a Gen III or Gen IV LS.
Bomb Proof mounts exist because rock crawling punishes stock mounts. Low gears, big tires, lockers and serious torque can tear stock mounts apart quickly. M.O.R.E.'s mounts use polyurethane bushings so there is no steel-to-steel contact, and in most applications they bolt to existing holes in the frame and engine; some installs may need drilling or welding.
This is an adapter, not a complete mount kit. It is only useful if you already own the JM200 or JM400 kit. M.O.R.E. also sells replacement body mount parts.
M.O.R.E. has been building off-road parts in Delta, Colorado since Chris Overacker started the company in his garage in 1978. Parts are designed in 3D CAD, cut on Mazak lasers and welded by certified welders, all in-house in the USA.

Specifications
M.O.R.E. Bomb Proof Block Plates (LS Adapter) FAQs
Is this a full motor mount kit?
No. It is a set of block plates that converts an existing JM200 or JM400 kit to fit a Chevy LS.
Which LS engines?
Gen III and Gen IV Chevy LS engines.
Will I need to weld?
Bomb Proof mounts bolt to stock holes in most applications, but M.O.R.E. notes some installs may need drilling or welding. Measure and test fit before you commit.
What does the warranty cover?
M.O.R.E.'s RockProof Lifetime Warranty covers product failure for the original retail buyer for as long as they own the vehicle. The powder coat or other finish and any rubber or urethane parts are treated as wear items and are not covered, nor are altered parts, improper installs, or fire and accident damage. M.O.R.E. repairs or replaces at its discretion; labor and shipping are not included.
