18" billet aluminum Antirock® sway bar arms as used in our universal Antirock® sway bar kits are available separately for builders or as replacement parts. Arms are machined from 3/4" thick 6061T6 aluminum, making the weight on these arms just 1.5 pounds compared to the 3.5 pound weight of the standard steel arms!
These arms are 18" long overall, making them 16.195" from center of splined hole to center of farthest 1/2" hole. Arms feature the 5 adjustable link mounting holes for fine tuning of the sway bar in custom applications. Sold as a pair.
NOTES: If you are upgrading a vehicle that is equipped with an Antirock® sway bar with steel arms, you'll need the 1/2"-20 thin nylock nuts shown below to reattach the heim joints to the arms! These arms can be used in conjunction with our RJ-201000-101 double shear end link bracket kit to add 1.5 in. in arm length and the ability to offset the end link up to 1.25 inches.
