I'm looking to put the Belltech 6400 drop shackles on my truck and am wondering if I need longer shocks or if the stock ones will work. Also, they will change the pinion angle if I recall, is it enough to worry about? I tried to search, but didn't find what I was looking for. Any help is appreciated!
I have the shackles but havent put them on yet so I'm expecting someone else to chime in. Stock shocks are fine. I know Griggs felt the need to put 2 degree shims to correct pinion angle but others have claimed a better pinion angle after install. It's not too much to worry about but just check it out after install. You can use shims or relocate your leaf perches as required.
i put a set of shackles on mine, didn't ever think of it changing the pinion angle but you i don't think get enough lift out of em to change how the axle sits. i've had no problems with mine thus far. i wouldn't worry about it if you want my opinion
