I think I remember something about them not helping a whole lot vs. factory type arms with urethane bushings. I know they had a history of ripping out the torque boxes.
You'd probably get a better answer in the regular 5.0 forum, I'm not sure if anyone in here runs them.
i have southsides on my car and they seem fine...just get your tq boxes welded...they may be outdated but they work, trust me...just a little harsh on the street...i might be switching to some MM lowers since my car is a daily driver
those are similar but different...if im not wrong, lakewood bought southside machine a while back.. i guess they tried making a copy liftbar SIMILAR to the southside liftbar...the steel bushings on the southsides make it a little harsh on the street...i like them alot
Looks like its a slightly different design off the HP Motorsport Mega-bite Jr's that I have. I like 'em, the rear end pushes down on launch instead of squatting down. Weight transfer is still there, it just pushes the axle into the pavement.
On the street mine are just as quiet as stockers...
