RockJock's billet aluminum Antirock Pre-Runner Sway Bar Arms are beautifully constructed, yet offer brute strength for aggressive off road racing applications! These arms are 35 spline, start out at 27.67 in. long, are 1 3/4 in. thick and provide maximum strength and rigidity via their 6061T6 billet aluminum construction and I-beam cross section design! Additionally, the arms are designed to be used as-is if the length suits your needs, or they may be trimmed down to fine tune their fitment to your build. For sway bar end link mounting, 7 adjustable holes are provided and are intended for use with our RJ-201001-101 Double Sheer End Link Bracket Kit.

The quality and durability of the arms are the best. They are super heavy duty. And lifetime warranty is crazy

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts. All around just seems like they don’t care.

Bought a new 2019 Ram 1500. Had bad rear wheel hop since new, got all four core 4x4 control arms and it fixed the issue. Thanks

I broke a grease fitting off in my end link. I thought I was going to have to buy a new one. Reached out to Core 4x4 and wham! bam! They fixed it and sent it back with 2 day shipping. Got it a day early even. If they couldn't fix it they were going to send me a new one. Now that's customer service! They are now a permanent part of my garage. Thank you Core 4x4!

Have full upper/lower CA set on both front and rear axles on a 96 ZJ. These are the rubber bushing sets not joint sets. I have beat the hell out it in the Nevada desert for 2 years and has been great. I don’t go fast but I do articulate suspension a lot. Super solid and haven’t any issues. Just inspected the entire set recently due to some banging under it. Turns out the banging is lower rear shock bushings. Inspected each CA along the way nothing. Aside from dirt and obviously winter roads and what not still in excellent condition, bushings are solid like the day they were installed. I’ll add that I’m about tapped on a short arm at 4.25(less with settle) so the front CA’s get beat on just from that, still they’re like new. Paint is great condition, this set is red. I would definitely buy again. Another plus for me, Utah isn’t local necessarily, but it’s nice to support businesses closer to me.

Got the CAMP version of adjustable control arms and track bars for our 03 TJ with a 3” lift and 33x10.5 KO 2’s. Super beefy bars, great fit and adjustability. Friendly advice and support from Korby at CORE 4X4. Good follow up as well. The ride quality is great as well as the handling. I think it all looks pretty good as well.

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.
