Upgrade your AntiRock sway bar system with these lightweight, CNC machined billet aluminum arms from RockJock Off Road are built for hardcore rock crawling and high end custom rigs.

Machined from 3/4" thick 6061-T6 aluminum, these arms deliver a massive weight savings over standard steel arms while maintaining strength, adjustability, and that undeniable billet cool factor. At just 4 lbs total per pair, they shed weight where it matters without sacrificing performance.

Each arm features five adjustable end-link mounting holes, allowing you to fine tune sway bar leverage for your specific terrain and driving style. The arms are clear anodized for corrosion resistance and a clean, high end finish, with engraved RockJock branding for a premium touch.

If upgrading from steel AntiRock arms: you’ll need 1/2-20 thin nylock nuts to reattach the heim joints (not included).

  • (1) Pair of 18" billet aluminum AntiRock sway bar arms

Tech Insight

Billet aluminum arms reduce unsprung and rotating mass compared to steel, helping your suspension react faster while improving ride quality and articulation control. The reduced arm thickness beyond the splines also improves clearance in tight chassis areas—especially useful in TJ/LJ steering box and frame mount locations.

For even more tuning flexibility, these arms can be paired with RockJock’s Double Sheer End Link Bracket Kit, adding 1.5" of effective arm length and up to 1.25" of end-link offset.
