I have searched for Monroe Gas Magnum shocks but they only listed the Reflex style available for my 2017 Ram 2500 with 6.7 Cummins. After driving them for about 3 weeks, they just jumped too hard on the local freeways and farmer's market roads that I have to drive on. I knew it was bad when my family noticed the excessive rebound. I replaced them with Rancho RS5000 series shocks, which handle and handle noticeably better.
