RPM Rod Ends cover a wide range of currently available Traxxas vehicles including all versions of the following: Slash 2wd, Slash 4x4, Summit,  T-Maxx, E-Maxx, Revo, e-Revo, Slayer Pro 4x4, Stampede 4x4, Rustler VXL, Jato and Bandit VXL. These rod ends are tough! The area around the ball stud is thicker than the stock rod end while still allowing a full range of motion of the pivot ball. Additionally, the shank has been redesigned with a pair of flats, making the rod end much easier to work with (versus the stock, round shank). RPM rod ends are sold in sets of twelve to complete most vehicle needs.
