Rear Lower Control Arm kit

Billy,

What is the significance of your rear lower control arm kit? What does it do better than stock?

Traditionally spherical ends are used to more positively locate a suspension member. Ours do the same for the rear end. We suggest using old bushings in the upper arms if still using them.

Our units are 100% bolt on. Make sure if looking at other brand arms that you do not need to drill out the chassis or rear end. See most supply 3/4 rod ends since metric rod ends are expensive and hard to get. We fixed that with a trick that has been used in motorsports for a decade. Ours use the stock mounting bolts.

Ok. Is that something that will drastically improve handling? or something one would buy after they've spent money on everything else?

Thanks for the reply.

I would put it in the "last few tenth of a second" category. You feel improvement with springs, shocks and swaybars. You will not feel the difference with spherical joints, the improvement is there just not as noticeable. This type of upgrade is truly a race car part.
