Well I am in the market for 2in drop shackles to level the back out on my 2011 HD AWD. Now the dilemma is which brand to go with. My options are Ford racing (comes w/ shims), ground force (comes w/ shims as well), DJM, or Belltech. As far as pricing they are all around the same. What I want to know is quality as well as do I need the shims? I've been doing some research and most say shims are not required for a 2in drop but I've seen people needing them due to driveline vibration. Any input/s would be greatly appreciated.

 

Get the Ground force or Ford Racing. The Ford Racing is probably made by Ground Force anyway....Better to have the shims and not need them to need them and not have them.

 

GF all the way.

 

My Belltech's do pretty good.

 

Ground force with the shims

 

Looks like I'm going with GF since it does include the shims and I rather be safe then sorry. I did read that the GF only drops the rear 1.5inch on a AWD and my truck has exactly a 2in rake. So it won't be exactly level but hopefully it won't be as noticeable.

 

Sweet! Can't wait to see the before an after pics. And glad I found your thread man. LOL

 

On my 07 FX2 (rear dropped from the factory...there was a shim.

 

Where is everyone purchasing the Ground Force Shackles from?

 

I got mine off of Amazon.
