Installed these (albeit red ones) a year ago. None of the vibration that others complain about with polyurethane motor mounts. Maybe they need to tune up their engines. I am running a 4” lift on my 4.0 YJ with a transfer case lowering kit. Everything runs smoothly and works well. I take my YJ off-road multiple times a month, so it’s not a trailer queen. Just need to find their Polyurethane transmission mount now. Mine isn’t broken, but I need to drop the trans, so that is the perfect time to install one.

Great fit and took care of the motor flex from hittin bumps and hard accelleration

If you’re buying a M.M.L. to correct drive line angles and vibration, you’re probably not going to be happy polyurethane. You’ll just trade drive line for engine vibration. Buy the JKS spacer and keep your rubber mounts.
