The Axial Yeti XL places extreme demands on front suspension components. Each RPM A-arm is designed from the ground up for strength, with massive support beams on either side and 30° leading and trailing edges to help improve transitions across ultra rugged terrain. All RPM A-arms are molded from RPM's ultra-durable blend of engineering grade nylons and backed by RPM's limited lifetime warranty against breakage.

• Hinge pin holes sized accurately, removing as much as 0.004" (0.1mm) of slop from the inner and outer hinge pins.
• Additional A-arm clearance around the bellcrank center-link allows for more up-travel without the severe impact stock A-arms and center-link encounter at full suspension up-travel, reducing the likelihood of a broken center-link.

RPM Yeti XL A-arms replace stock Axial #AX31018. The Yeti XL RPM reviewed had A-arm hinge pin holes that were roughly 0.004" (0.1mm) – 0.005" (0.13mm) oversized from nominal. Furthermore, the hinge pins were roughly 0.005" (0.13mm) undersized as well, creating as much as 0.01" (0.25mm) of combined suspension slop. Nominal sizes are 0.118" (3mm) and 0.1575" (4mm). RPM recommends checking your hinge pins for size and replacing them with on-sized pins (not available through RPM) for dramatically improved suspension performance above and beyond the improvements created when installing RPM A-arms.
