Madman offest LCA's?
 
Just a quick question really... Is it normal that when shortened all the way, these are only about 1/2-5/8" shorter than stock?

It seems its going to be just short enough for my 28x10.5's to clear the wheel wells correctly, just not completely centered.. Off just a little bit with no more adjustment.

Are your relocation brackets welded on with the bolt holes arcing forward??

Relocation brackets... I welded them on according to BMR's instructions of doing one at a time while leaving one LCA in the stock location while doing the other. They are fine, I used the stock LCA's when I weded them.

When comparing your lca's side by side with a pair of BMR non adjustables: I turned the rod ends all the way IN to the LCA body, making it as short as possible. The visual (not actually measured) difference between the BMR piece and yours is approx 1/2-5/8" shorter. I can go lots longer, but only 1/2"-5/8" shorter than stock.

make sure your rear is able to be aligned correctly.

Thats the whole thing. Im hoping that it can be with these LCA's...
I thought adjustable meant they would be adjustable in both directions at least close to evenly. Obviously not though :bang:

take a pix and attach it. i have a feeling the LCA relocs were not welded correctly. there should be plenty of room. i have SJM double adj LCAs and they are identical

There is room and the tire does clear now. Where it didnt before.
Its just that I cant adjust to exactly center the wheel due to lack of travel.

The whole point is that they only adjust down to be about a 1/2"-5/8" shorter than stock. I will take a pic of what I'm talking about and measure it based on mounting points centers as best I can.

My question for everyone is if the LCA's should be capable of going shorter than they are going?

Stock lenth LCA with +/- 3/8" should work in most set-ups.

Do you have to run LCA relocation brackets? What do these do? Sorry..I know it is dumb question.

Thanks!

jshiver-
Dont HAVE to but theyre nice. They allow you to point the rear of the LCA downward. Which in turn helps to plant the tire into the ground when the axle tries to twist the pinion upward with torque. Basically the relocation brackets make the LCA's act like a lever pushing down.

Lowered cars need them to correct geometry after the lowering. The LCA's will actually point upward when a car is lowered.
