I've been driving in circles for hours and I only have 150 miles out of the way. I want to see how good the Trutrac will throw the truck all over the place dammit!!!!

 

Just let it eat..

DUsitn

 

what is the proper break in for it?

like the motor is 1,500 miles nothing over like 2,500 rmp or some **** like that

 

all driving under 55

drive 15min . . . then stop and cool off for 15min
drive stop and go for 30 . . . cool for 30
then drive 500 miles, , not going over 55

dump oil -again, lay black marks

 

Sorry, but to me gear breakin is the stupidest thing I've ever heard. Do you break your gears in on a new truck? Flat out every vehicle I've ever bought new I've taken on the interstate on a long extended road trip of 70-85MPH to break the engine in. My truck was driven for 12 hours straight off the dealer lot from blanchard, ok to minneapolis mn at speeds no less than 70 unless I was pulling off for gas. If you installed the gears right I would just go have fun with them immediatly. If you feel the need to do something then change gear oil at 1K miles and call it a day.

 

the really bad thing is towing. seen multiple rear ends cook from guys towing right after a swap. oh well...their bad not mine...suckers.

 

i left the gear shop sideways around 10k ago and have yet to have problems. my gear man even recomended it lol. the cam n heads sure did suck to breakin!

 

thats cause your impatient!

 

fails to mention......he IS the gear man lol
