quick question, will an 07 classic flip kit fit my NBS 08 gmc single cab?

 

i would take a guess and say yes

 

my guess is yes as well as long as the u bolts are long enough the axle mounting perch should be the same you should be able to check just by sliding the u shaped bracket under the perch and the u bolt over all of it before you even take every thing apart by the way those u bolts aren't cheap so if they are to short you're screwed

 

yea well im tryin to save a buck since all the f-ing parts for these damn NBS trucks r so damn expensive...hopefully u guys r right.

 

Take a measuring tape and measure the old style truck to the new style truck. Chevy has used 3" axle tubes since the times of Jesus, but some of these new leaf springs are wider then before.

Summit racing sells a 3" leaf spring bracket for $25 So if you have a welder and a 4" angle grinder you can do a flip kit cheaper.

1st pull out you axleset it up on jack stands upside down with the pinion at 3-6 degrees down. Then pace your new perchs on the axle and set them level. Then tack them in a touch, and make sure there level side to side. When this is verified you can positively weld them in. Then cut off and grind your old perches down. Repaint to taste. I personally think this is better then a clamp togather kit, and if you have acees to the tools much cheaper and better.

If you plan to go down further you'll have to consult a shop who can shorten you driveshaft atleast 3/4 of an inch. If your plans call for a 9" rear drop shrten it 1 inchy.

Also if you wanna be cheap in the future you could get lowering blocks instead of some ways, and there damn cheap to.

Remember shocks maybe if your imediate future as 4 inches is a lot of drop. You'll want about 2 inches of shock travel atleast to be safe.
