core 4 x 4 control arms

[Jack.]

Does anyone know the different between tier 4 and streets? looking to prob replace my stocks ones with these and grabbing the end link too while i have everything apart.

The tubing on the streets is 3/16th and tier 4 is 5/16th DOM tubing.
Tier 4 has Forged Currie Johnny Joints and street version has rubber or poly bushings.

Also the adjusting threads are beefier on the tier 3 and 4.

I have the tier 4 end links for when I do my rear shocks and new springs. Same price as the street ones so may aswell.
