The OM617 is in my 89 Jeep Wrangler, 4" lift, 32" tires, 3.73 gears. Not too concerned about top speed, at about 70mph, it gets a little scary, 80 feels like your in a mac truck going 110 across a 1 lane bridge with heavy cross winds...

Really looking to pick up on the off the line acceleration without having to regear, I just dont have the time, space, or money to swap axles right now. Throwing on a K26 should only take my about an hour or two...
