Since Feb. I've had the 5.38's in my pick up (stock 4.55/31's). With the 33'3 it feels like a new engine.

I have 167,000+ miles on it and can sustain 65-70 mph on grades (I'll be running up Hwy 50 early May, Randii's neck of the woods <img src="/forums/images/graemlins/coolg.gif" alt="" />, I'll get a true test then <img src="/forums/images/graemlins/baby.gif" alt="" />).

Haven't seen much of a difference with gas milage <img src="/forums/images/graemlins/kewl.gif" alt="" />. My last fill up was calculated at about 19mpg. That's not taking in consideration of tire size/gearing change over stock. Straight freeway I think I can get well over 200 miles on my 14 gal tank. <img src="/forums/images/graemlins/smile.gif" alt="" />

I'm real satisfied with the 5.38/33's combo.
