Motor Mount Lift (MML)- Is needed when doing any high clearance t-case skid on a Jeep that has a suspension lift of 2” or more. Stockers can usually get away with out it, but if you are doing a tummy tuck chances are you aren’t keeping the stock suspension height. There are various ways to lift your motor which include JKS(spacers-$60), Brown Dog(full replacement-$84), and M.O.R.E(full replacement-$139). If you choose new motor mounts instead of the spacers, get the rubber bushing versions to reduce engine vibrations. Poly bushings **can** transmit more engine vibrations, but they greatly reduce engine movement and will not degrade as fast as rubber. Rubber's lifespan is usually a few decades...so its your choice.
It's intuitive why a body lift is more or less needed. But why a MML? I've noticed a lot of conflicting information here on the topic, some directly from Brown Dog IIRC.
Awesome right up. For sure needs to be a sticky on this.
