To keep the axle centered you will need an adjustable panhard bar or a drop bracket for it. You will also need adjustable or shorter sway bar end links to keep it level, but you dont need a whole new sway bar

 

On my 2011 Express, I did the Ground Force 2" rear drop, it came with springs and new shocks, rode good as new.

 

Any pics?

 

Graygoose- Did you use an adjustable panhard bracket and or new end links?

Thunderhorse- Do you recommend a certain brand for the bracket and end links?

Thanks to both of you!

 

Hellwig makes a popular adjustable link swaybar, and Spohn makes an adjustable panhard that negates the need for a bracket. Belltech makes a kit that has springs, shocks, and the panhard bracket

 

No, I just sued what was in the box. I don't think you need endlinks unless you go more than 2" drop. Now when I did the BT 2/4 drop, yes, I did adjustable endlinks and Hellwig endlinks.

Here is just drop 2" with the GF kit

 

another with factory wheels

 

with Nitto 420s 22's and KMC Slides. Drove EXCELLENT this way

 

I like the looks of the rear being a bit lower, but wonder what affect this will have on the towing ability. Or with a full load in the bed. Will the bed then be too low?

 

You'll just hit the bump stops sooner

 

Add some Airlift 1000 bags, be set. Easy to put in while swapping rear coils.

 

Airbags would work, thanks.

 

I lowered my RCSB four inches in the rear with shorter coils. I had the airbags installed at the same time. We pulled a heavy motorcycle for 600 miles. The first 300 I added air to the bags but with a 275 lb toung weight and nothing in the bed it wasn't necessary. On the return trip no air was added and the fender only dropped 1/4 inch. Never hit the bump stops. The front of our truck has 2 inch drop spindles.
