Designed for universal fit across all 25-spline Antirock torsion bar applications, the RJ-202001-103 arms are the same forged chromoly components found inside RockJock's bolt-in Antirock kits for Jeep JL Wrangler, JK Wrangler, TJ Wrangler, LJ Unlimited, Jeep Gladiator JT, and first-generation Ford Bronco platforms. Sold as a pair with arm stickers included.\u003c\/p\u003e\n\n\u003ch4\u003eForged 4140 Chromoly I-Beam Construction\u003c\/h4\u003e\n\u003cp\u003eThe RJ-202001-103 uses a forged I-beam profile throughout the arm body, giving them dramatically higher strength and rigidity than fabricated or bent-steel alternatives. The 4140 chromoly material is heat-treated to deliver the toughness required in rock crawling and extreme off-road use where sway bar arms experience constant shock loads and torsional stress. At the torsion bar end, the arm is 3\/4 inch thick with a 25-spline bore and a vertical pinch bolt hole for a solid, rattle-free attachment to the bar. At the end link mounting end, the arm tapers to 3\/8 inch thick and provides three 1\/2-inch end link mounting holes, giving you the ability to adjust leverage on the torsion bar to tune your suspension stiffness for your specific build and tire size.\u003c\/p\u003e\n\n\u003ch4\u003e2.5 Inch Offset Bend\u003c\/h4\u003e\n\u003cp\u003eThe 2.5-inch offset in the RJ-202001-103 is engineered to provide component clearance in the tight packaging environments common to JL, JK, and TJ front Antirock installations. The offset moves the end link attachment point inward relative to the torsion bar centerline, addressing frame, shock, and control arm clearance issues that a straight arm would not resolve. This geometry matches the factory arm configuration used in RockJock's complete kits, so swapping to the RJ-202001-103 as a replacement or upgrade preserves the original tuning intent of the kit.\u003c\/p\u003e\n\n\u003ch4\u003eUniversal Fit Across 25-Spline Antirock Bars\u003c\/h4\u003e\n\u003cp\u003eThe RJ-202001-103 fits any Antirock torsion bar with a 25-spline interface. This covers the full range of RockJock's common torsion bars used in JL, JK, TJ, LJ, JT, and G6 Bronco Antirock kits. They also work in custom builds and rock buggies using 25-spline bars from RockJock or compatible sources. For builders using the RJ-201000-101 Double Shear End Link Bracket Kit, the RJ-202001-103 arms can be used in conjunction with that bracket to add 1.5 inches of effective arm length and up to 1.25 inches of end link offset adjustment.\u003c\/p\u003e\n\n\u003ch4\u003eFinish and Stickers\u003c\/h4\u003e\n\u003cp\u003eThe RJ-202001-103 arms are finished in a textured gloss black powder coat for corrosion resistance and durability.

In practice, this covers Jeep Wrangler JL, JK, TJ, and LJ Unlimited front and rear Antirock kit applications, Jeep Gladiator JT front Antirock kits, first-generation Ford Bronco (G6) front Antirock kits, and any custom build using a 25-spline RockJock Antirock torsion bar. If your Antirock bar has 28 splines, you need a different arm such as the RJ-252201-103.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAre the RJ-202001-103 arms a direct replacement for the arms that came in my RockJock Antirock kit?\u003c\/strong\u003e\u003cbr\u003e\nYes. The RJ-202001-103 is the same forged chromoly arm included in the CE-9900JLF, CE-9900JKF, CE-9900TJR, and RJ-286100-101 Antirock kits, among others. If you bent, cracked, or lost an arm from one of those kits, the RJ-202001-103 is the correct replacement part. Confirm your kit number against the compatible kits table above before ordering.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo the RJ-202001-103 arms come with end links or mounting hardware?\u003c\/strong\u003e\u003cbr\u003e\nNo. The RJ-202001-103 includes only the pair of forged arms and a pair of stickers. End links, pinch bolts, and other installation hardware are sold separately. For a complete hardware kit for existing Antirock bars, RockJock offers the CE-99005A arm hardware kit. End links are available separately in the RockJock catalog in various lengths to suit your lift height.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between the RJ-202001-103 forged arms and the fabricated steel arms?\u003c\/strong\u003e\u003cbr\u003e\nThe RJ-202001-103 uses a forged I-beam construction from 4140 chromoly, which produces a denser grain structure and higher strength-to-weight ratio compared to laser-cut or bent fabricated steel arms. The forged arms are 3\/4 inch thick through the body versus 3\/8 inch for typical fabricated arms, making them significantly more resistant to bending under extreme suspension articulation and rock crawling impacts. The trade-off is higher cost. For standard trail use and wheeling, fabricated arms are sufficient; for extreme competition or high-impact use, the forged RJ-202001-103 arms are the better choice.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use the RJ-202001-103 arms with the RJ-201000-101 Double Shear End Link Bracket Kit?\u003c\/strong\u003e\u003cbr\u003e\nYes. The RJ-202001-103 arms are compatible with RockJock's RJ-201000-101 Double Shear End Link Bracket Kit. Adding this bracket increases effective arm length by 1.5 inches and provides up to 1.25 inches of additional end link offset adjustment, which is useful in builds where more leverage on the torsion bar is needed or where clearance is tight.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow does the 2.5 inch offset on the RJ-202001-103 help with component clearance?\u003c\/strong\u003e\u003cbr\u003e\nThe offset bend moves the end link attachment point inward toward the vehicle centerline relative to the torsion bar mounting point. On JL, JK, and TJ applications, this geometry keeps the arms clear of the front differential cover, control arm mounts, and frame rails that a straight arm would contact at full compression. The 2.5 inch offset on the RJ-202001-103 matches the geometry used in RockJock's complete bolt-in kits for these platforms.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes the RJ-202001-103 work on a Jeep TJ rear Antirock setup?\u003c\/strong\u003e\u003cbr\u003e\nYes. The CE-9900TJR TJ\/LJ Unlimited rear Antirock kit includes the RJ-202001-103 forged arms as its standard arm component. If you are building a custom rear Antirock setup on a TJ or LJ using a 25-spline bar, the RJ-202001-103 arms will fit. Note that rear Antirock installations on TJ and LJ vehicles typically require some trimming of inner fender liners and, in some cases, minor sheet metal work for full arm up travel clearance.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat warranty does RockJock offer on the RJ-202001-103?\u003c\/strong\u003e\u003cbr\u003e\nRockJock backs their Antirock components against defects in materials and workmanship. Contact RockJock directly at rockjock4x4.com for full warranty terms. Damage from improper installation, impact with obstacles during use, or racing is not covered under a standard defects warranty. The RJ-202001-103 is intended for off-road use, and some body roll increase compared to a stock sway bar is expected behavior, not a defect.\u003c\/p\u003e\n\n\u003ch4\u003eCalifornia Proposition 65 Warning\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eWARNING:\u003c\/strong\u003e This product can expose you to chemicals including lead and chromium, which are known to the State of California to cause cancer and birth defects or other reproductive harm.
