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! Sold as a pair.
NOTES: 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. 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.
