RPM WING MOUNTS ARRMA KRATON, TALION, TYPHON, DEX8/8T/DNX8 RPM Wing Mounts solve the key breakage issues reported to us. Primarily, the front cross brace holes were cracking. Our simple solution was to eliminate this hole in favor of a flat plane of solid RPM engineering grade nylons. We then swept the entire mount on a curve to help add some impact flexibility when it needs it most – during a crash. When running normally, the massive amount of material we used keeps the wing locked in place, providing excellent, stable down force on the rear of the vehicle. RPM Wing Mounts are sold with one left and one right wing mount to replace damaged or broken stock versions. They’re molded in our trademark blend of extremely strong, engineering grade nylons for a lifetime of durability and performance.Tech Notes: RPM Wing Mounts replace stock ARRMA #AR320194 and stock Durango #TD320274. RPM Wing Mounts contain support bars only and will require the use of the stock ARRMA / Durango wing, two stock cross braces and stock mounting hardware.
