Howdy. Things are tight in my TJ's back end. GenRight extended range tank, larger cast iron diff cover (diff turned up to match angle with the double cardan rear shaft), Banks Monster exhaust. I've just found that the Banks pipe is too close to my right rear Rancho RS55240 shock. A smaller diameter shock would help. I like the Rancho ride, going with the H&R springs. Can any of y'all recommend a smaller shock?
