The undisputed champions of X3 trailing arms – the strongest and most trusted option on the market, bar none.
Beginning with our renowned boxed design, a decade of proven excellence in our product line, these trailing arms match the pedigree of our A-arms. With these trailing arms, you'll enjoy over 4 inches of added ground clearance, but the true game-changer lies beneath the shock mount, where you gain over 2.5 inches of usable clearance right at the front of the tire. Constructed from a blend of .115" and .1875" Grade 50 steel, these arms not only tolerate rough treatment but actively embrace it. The brake line bungs within the arms feature sealed bottoms, preventing intrusion into the arm's internals and secured with the supplied 6mm hardware. The removable back strap piece on the trailing arm's rear side eases installation. With over a quarter-inch of material thickness on the bottom side of the arm, these arms are built to withstand desert cruising or rock bashing without flinching. They are bolt-on compatible with factory shocks, requiring no modification.
For those seeking additional customization, Smart Shock mounts can be added upon request.
Please note that if you plan to order this part in its bare form for powder coating, it's crucial to avoid sandblasting or powder coating the bore of the uniball pockets. These parts are machined to exceptionally tight tolerances, and any deviation will affect uniball and snap ring placement. In such cases, we cannot warranty the item due to improper fitment or installation of the uniballs.
Rest assured, our arms are backed by a no-nonsense lifetime warranty, and you can find replacement wearable items at the bottom of this page. Elevate your X3 with confidence and durability.
