I forgot to mention mine has 4.56 gears.
My original rear end was a two speed with 6.17 and 8.17 ratios.
It was awesome and I wanted to keep it but I also wanted to travel at highway speeds.
That is why I put the P30 axle in mine.Massive disc brakes too.
With the discs in the back,P30 discs in front and the hydroboost master cylinder my truck will lock up all 6 tires instantly.
Master cylinder is mounted behind the cab and is actuated through a bellcrank from the pedal.
Better brakes than my modern Silverado diesel.
