Pinion Angle On A Nnbs

illMATTic · November 21, 2009

I just dropped my truck 4/7" last week. I didnt record the pinion/drive shaft angle before I did it. I was wondering if any of you had any tips or specs I could use.

thanks, Matt

Any pics of the truck?

Only one right after I got done. The weather has been garbage here so i havnt been able to get the photos I would like.

I have a bit of vibration upon takeoff right now. I just need to know which way to adjust the rear end. I have a DJM flip kit on it. I just made sure it was even on both sides. I dont know if I nee to go up or down so I was hoping to get a stock measurement.

Wish I could help you out but I'm not sure about lowered trucks. More of a lifted truck guy. But the truck looks good lowered. Got a plan for new rims?

Sorry...nothing useful to add here either.

Just wanted to say nice job....I'm not a fan of lowered either...but It looks good man.

And that's a nice clean install. I would definitely use that kit if I were to do something like this.

Raised, lowered or stock the pinion angle should be the same. I think it is about +.5 degrees of the frame angle static. If it is at that angle and there is a launch shudder the nose of the diff is pitching up more then 18 degrees and needs to be stabilized.

ouch that just gave me a headache. I don't do those angles often if ever. I can't find them in the manual's, what you got there is a distant memory from a class I took probably 10 years ago.

From the sounds of that...and the pic of the flip kit...I would say it could be rotating slightly inside the flip kits brackets and you may be getting axle wrap on acceleration.
