99 Tahoe, Flip Kit, Drive shaft issues!

[J-dub]

Well I finally got the drop on my Tahoe, BUT with the flip in the back my driveshaft is rubbing in 2 spots and I've even cut into the crossmembers.

If I do a 1.5" lift shackles will that solve my problem?

I'm going to run 24s so I was eventually going to have to come up a bit anyways.

Also, what's the best way to properly set the pinion angle right again?

The only issue is the rubbing, or vibrations also? If you have vibrations you have to correct the pinion angles by putting angled shims on the leaf spring pads.

Not sure about the rubbing I don't know too much about 5-6" drops. I will say if the driveshaft is hitting you either has to raise the truck back up or cut out what is rubbing. You might bend the driveshaft if you don't.

Shackles will affect the pinion angle. If it isn't vibrating now, it will if you put shackles on it.

Hit up Norcal

When you put your flip in you are supposed clearance a few spots so it does not hit when your suspension cycles.
Did you do that?
The crossmember above the rear needs to be clearanced and the crossmember in the center of the body needs to be cut.

These are some pics I took when I did my drop.

Whoops

James, do you have a 4 door or 2door? 992dr obviously has a 2 door and the crossmembers arnt the same as the 4 door.

I just put a flip kit on my tahoe, im rubbing the center crossmember but youll have to adjust your pinion angle. Or make sure its right.

This was a picture with lowering shackles in the back with the flipkit, which was way to low in the ass, so this weekend i just put in some lift shackles and now all 4 corners are dead nuts even and looks way better.

I figured out the issue....
I notched the X members and solved most of it then added a 1.5" lift shackle and it never rubs now. Pinion angle still isn't perfect but it is close now after using 4 degrees of shims on each side. Unfortunately the Tahoe is going in the opposite direction here soon. But if anyone has any questions on how to stop the rub they are welcome to contact me. I worked on mine for a good 4 days to get all of the rub gone. The ride isn't too bad but I'm running drop shocks on all 4 corners. For some reason mine was tucking near 2.5" of tire with my flip and no lift shackle and is still tucking about 3/4" now.

Truck looks good Adam!

 

[AtomicHoe094]

have a picture of yours? and thanks!

also if its a DJM flip kit, those kits dont need pinion angles since you can loosen the bolts and swing the pinion angle any way you want, tighten the bolts back down and its locked in place..

What flip kit do you have?

Glad you got it all figured out.

 

[AtomicHoe094]

i thought DJM was the only company that sold one for our trucks unless you used belltechs from a different application... could be wrong tho

 

[AtomicHoe094]

This is what i did tonight.


should never hit now, ive heard of people bending drive shafts with this lowering kit.. better safe then sorry

 

[992dr]

Belltech and DJM make kits for our trucks, maybe even McGaughys (spell check).

You must have a 4 door. Looks a little different than mine. I'm going to have to get under mine to get a shot like that, looks cool.

So, everything is clearing without any problems?
I hope, bending driveshafts is no good, hah.

 

[AtomicHoe094]

Yea a few different crossmembers in the way. i rubbed the driveshaft once and said thats enough time to notch. i was just test driving the truck too... I need to figure out a pinion angle still. im at 2* at the pinion but not sure if i should go mroe or less.

I actually have a Western Chassis kit from a 97 Silverado. It's basically the same kit for all years for leafs in the back. The Western Chassis kit is NOT adjustable and I would never recommend it on a Tahoe for anyone else. I'm also running stock shocks because with lowering shocks it brought it down even MORE. I really think the bracket with the western chassis kit is thicker making it as if there is about a 1.5" drop block compared to a DJM kit. I don't have any pictures but basically I've notched every crossmember, put lift shackles, 4* of pinion shim, and my pinion angle is STILL way off. I'm going up, lol.

When I do my lift I have to replace a driveshaft now, as well as re weld the crossmembers where the driveshaft bent the notches I cut.

 

[AtomicHoe094]

yikes.. sounds like something went wrong. usually truck lowering kits are about 2 to 3 inches lower then a suv lowering kit..

 

[J-dub]

That's the true problem. I didn't want to fork up the cash for a Tahoe flip kit. Lol.

Oh well, lift is in the mail now

 

[992dr]

Just curious.What was the difference in cost between the pick-up and tahoe flip kits?
I dont remember exactly how much mine cost, it was roughly $900. That included spindles, coils, flip kit and shocks.

 

[AtomicHoe094]

what brand did you get 992dr??

I have way too much invested in just the whole truck, wish i would of never started. lol

 

[J-dub]

I payed $70 for the flip kit. It was about 3 days old.

It was all Belltech but, I have since changed the coils to Hotchkis and shocks to Bilsteins. I need new shocks, the Bilsteins are for stock height. Though they did say they woulld work with the drop. The ride sucks to say the least.

Well, you certainly didnt fork out much, hah. As far as I know, the flips are compatible from the pick ups to the Tahoes. I think.
