I would like to lower the back of my 2004 F150 to be even with the front.

Has anyone done this?

Could you let me know what’s involved and the cost associated with it.

Do any of the 'new' guys ever use the search before asking a question?

 

no

 

Whats search?

 

Don't some of you old school forum hangers have something better to do than reply to a post that has nothing to do with you.

 

Well if it had nothing to do with us than you would of never had your question asked...

 

I used the search button for this one. The answer was NO!

 

I used the 2" Ground Force shackles to lower the rear of my truck. The Ground Force shackles come with the pinion angle shims and cost about $80. DJM also sells a 2" shackle w/o the shims. The DJM's are cheaper but I dont know how much. Some have used the DJM with no problems and some have developed a slight vibe with them. I say spend the extra $$$ and do it right.

 

<Search Results> DJM shackles are better than Ground Force; no shims needed

 

Thanks jpdadeo

 

some of the DJM boys with a vibe will disagree.

Listen to GB150

 

The brand of shackle, whether it’s Belltech, Ground Force, DJM, etc, has nothing to do with the perceived vibration some trucks have. If you are only dropping 2” to level the truck, you may or may not need to shim the pinion angle. Lowering the rear with drop shackles in essence raises the differential therefore to restore the factory angle you shim between the axle and leaf spring to bring the front of the pumpkin down.

 

I wasn't saying that Ground Force was a better shackle than the DJM shackle. I'd imagine they probably about identical. All I was trying to say was that since the Ground Force comes with the shim that to me it was worth it to spend a few extra $$$. I know some have the DJM with no problems. I've had my Ground Force (with shims)on for about 12,000 miles now with no problems.

 

Flip a coin!
