4" rear drop performance

[fordification]

Either its all in my head or there is a slight change in handling from dropping the back down. As far as handling in a truck goes, it just feels like it stays square with less body roll around the corners.

It actually measured out to be 3" at the bumper and 2" at the wheel.

Also the 180 rotation on the shims worked great.

I'll need some better photos.

nice... now take out the helper leaf and youll get another 3/4 of an inch and that might level her out

that has to be an 03/04....the rears on those suckers are jacked high! my buddy has a 04 and i cant believe how high the rear sits!i guess the 99-02's got the crappy heads with lower suspension out back and the 03/04's got the good heads and jacked rears lol and fordification...go to the how to's and get that front bumper gap taken care of!

That's a 4" drop? Needs another 4 .. LOL those 03-04's are jacked up so high lol.. You will notice a change in performance with the drop for sure..

Looks like I might have spoke too soon. I can here a slight vibration at low speed/deceleration. no other time, even at 100+.

With this tire/wheel combo, any big drop would make it look funny. I want to keep an even gap around the wheel well.

Helper leaf would give it that extra 3/4" to even it right out but thats probably it for getting the angle with the shim flip.

With the wheel and tire combo? Big drops on stock rim/rubber look sweet, no need to go pimpin' with some big 22s or anything.
Don't have to Pimp your ride Xzibit style like Infamou$ did rollin' around on 23s

It's all personal preference. I'd rather have the wheelwell hug the tire right around the edge.

The drop is probably all the cosmetics I'll be doing. I'll be leaning toward the performance end now.

What are you going to do up front?

What are you going to do up front?

Was thinking of doing some 1.75" eibach springs, but have heard they can sacrifice some of the ride. Between that and having to do an alignment, not sure its really worth the 1.75" drop. Any recommendations?

 

[MJG]

My friend has the eibach springs, my advice, don't bother.
If you want to retain ride quality, do 2" spindles up front. You will lose turning radius slightly, if that means anything to you.
You could do lower control arms but I have no experience with those to vouch for ride quality.

Looks just like my 04. Nice and level. I'm planning to drop mine too. Going with the same set up as ss this had.

Any ideas on adjusting the shims for the low speed vibration? I read half a dozen posts saying they had the jlp's and rotating the shim without any problems.

are those the JLP drop shackles..?

They are. I have read countless posts of others using it and the 180 shim with no issues.

So my first mod turns out to be fail cause she's definitely grinding at low speeds.

 

[MR-BOLT]

The JLP shackles do not give you a true 4in drop!

I'll have to pick up an angle finder and see what shim I need. was hoping the 180 would do it.

 

[fordification]

Here's some more pics. I just love the stance now. And I know its just a truck, but I can feel it hugging the road alot better.

 

[fordification]

So I bought this angle finder and I thought I could get it to work but its very imprecise.

I was thinking of trying this and just subtracting the shaft angle by the pinion/u-joint angle.

I can get what looks like a level that digitally measures angles for $90. And I will probably need it again for building my 68 coupe.

Any suggestions?
