RPM A-arms for the T-Maxx 2.5R, 3.3 and E-Maxx 16.8 are built to handle some serious abuse. We've redesigned these a-arms to compensate for the larger axle diameters of the 2.5R, 3.3 and 16.8 with axle clearance zones built right in, yet these clearance areas do not compromise the strength. These A-arms are lighter than ever before, yet still maintain all of the qualities that RPM customers have come to expect from RPM A-arms – rugged durability, unrivaled performance, strength comparable to or better than many alloy A-arms, yet are lighter than those same alloy parts and pricing unbeatable by any other aftermarket A-arm set existing. All this and we back our A-arms with the best breakage warranty in the R/C industry. We mold these A-arms in four different color choices, including a dyeable version for the ultimate in customization options and are sold in packages of one upper and one lower A-arm.
