I know it is bad to use bolt in sub-frame connectors because the chassis flex with eventually make the holes bigger and make the SFCs useless. Will the same thing happen with bolt in LCA relocation brackets?

 

eh thats tough to say... i have UMI's bolt in... the bolt ins are alil better bc they are slightly thicker and have more material, they can always be welded in if needed and they have a sexy powder coat they are made stronger cuz they are being bolted in and arent welded. of course u can weld em and make it even stronger...

as far as elongating the holes... i dont think so... i mean they see diff forces than a twisting subfram does and they are supported by the stock brace from the rear. basically the bolts just hold the brace so it doesnt pivot outa the way. i say get em and if ur really worried get em welded in but once u do that u can get em off and ur stuck wit that rear. i havent done that for that reason and ive had mine on for over a year.

id get new hardware tho as well.

 

they are pretty strong. and like said above, they can always be welded in as well.

the only "weak" spot would be the tab that mounts to the shock mount. there is stress of the bracket and i guess it could fatigue and break, but ive never heard of it happening yet.

 

The bolt-in relocation brackets are actually better because they give a positive location for the bracket to be installed. Weld-in units have a little play where they could be installed slightly different side to side and still look the same. Best bet is to go with bolt-in brackets and weld them in once installed.
