I have used MC And RK i wasn’t happy with MC on my Diesel even using front spring correction pads the would bow, so Rock Krawler i had on my Gladiator was super awesome and could handle weight very good towing a trailer, call RK and ask them what they recommend for your Jeep. They are cool guy’s...
I can’t remember i traded this Jeep in for a new one, it flexed good with this set up i only added spacers because of the apex sway bar links would rub when unlocked.
