I have a C3500 GMT 400 truck. Can I use your 4X4 GMT 400 motor mounts in my truck?

Category: Common Questions

Our motor mounts will fit in your truck with a fair amount of fabrication work. The pedestals that are welded to the cross member need to be removed. Holes need to be drilled in the cross member to bolt in our lower motor mount. The nuts on the lower mounts would be accessed through the spring pockets. The cross member will need to be relieved so that it will clear the oil pan. The relieved section will need to be boxed and reinforced to restore it’s structural integrity. The cross member is a an integral part of the suspension, therefore these modifications should only be performed by an experienced welder/fabricator.
