What transmission and rear end are you running in your truck TJ?

You mean 150 HP at 4,000 rpm and 230 ft lbs 2,000.
I am running the stock transmission( 4 speed on the floor) and the stock C-10 axle. GM 12 bolt rear axle...gear ratio probably 3.90 or 4.11. The only reason I rev it to 4,000+ between shifts is the rpm travel between shifts...2nd to 3rd is almost a 2,000 rpm split..if I was to rev it to 4,000 in 2nd then shift to 3rd my rpms would start just around 2,000 rpm....3rd to 4th is worse, But hey...these weren't made for speed. lol...which I am going to change to a richmond 6 speed...5 direct gears and a 6th gear overdrive. Spendy, but worth it.
