Yea i just got my ground force shackle drop in and it didn't have the pinion correction wedges, Does anyone know what degree they are. (3 or 4 degree).

Reason why there is a place right down the road that has them i just need to know what degree. Tks

 

You might try the Ground Force web site.

 

I was told that 1* for every inch of drop

 

Tks.

Yea i tried their web site it is down lol , called them , an that is why i turned to this forum

 

You get some vibration or other problem on newer trucks if you don't shim?
(Put the shackles on my '98 without shimming.)

 

Well talked to ground force today, its a 2 1/2 * wedge, incase anyone wants too know.

 

When I bought my 2" kit and had it installed. I told them the reason I wanted the Ground Force was because it came with the wedges. They brought my truck around after installation and the wedges were still in the box. The installer said it didn't need them as I had the two piece driveshaft. I told him, i wanted them installed as the pumkin would be out of alignment even if it didn't vibrate. They went back and installed them.

 

blue you shoulda had me do them for you

yes its roughly 1* for every 1" drop, but not always. Only way to see exactly what you need is put your drop on and check the driveshaft angle with the appropriate gauge.

It is the pinion angle you are worried about.

 

You would have no problems without them unless you were loaded but 2 degrees will be plenty and make sure you put the fat side of the wedge on the front when lowering.

 

you sure the directions say's to put the "fat side" to the rear. ?

 

Fat to the rear is for lifting because when you tighten the u bolts down the axle will suck to the gap which will turn the axle upwards towards the transfer case. Since your truck is lower the driveshaft angle needs to come down.

 

Yep, it seems backwards but isn't.

If you put the shim in with fat to the back it will be the same as putting on a 4" drop with no wedge. Go to beltech's website and under the tech support - install sheet - kit 6419 - step 18 which is for the 97-03 it will say the fat to the front. If you want to put it fat to the back then go for it but you'd be better off just not putting the shim in at all. Just think about it for a second and it makes sense. The axle has to move wherever the gap is because the leaf springs definitely won't be the ones to move. If the gap is towards the front then the driveshaft will suck upwards which is good for lifted trucks and bad for lowered ones. If the gap is to the back the driveshaft will go downwards which is what you're looking for.

 

When drop shackles are installed the spring pack pivots up towards the truck bed, therefore making the pinion angle pivot up towards the truck bed as well, which makes the pinion angle wrong. Adding the shim with the fat part towards the rear corrects that wrong pinion angle back to stock.
