When it comes to rod ends, RPM rod ends are the basis for comparison! Our rod ends are strengthened in all the right places, they are molded to the strictest of tolerances, & are molded from our blend of tough, durable nylons. They maintain our close tolerances over the ball stud and have the same oversized hex as our 4-40 standard length rod ends but these versions are longer and also include a small recess at the top of the ball to allow steeper angles without binding! If you’re tired of popping and breaking stock rod ends, RPM rod ends are the solution!

Tech Notes: RPM 4-40 rod ends are designed for 4-40 (or 3mm) turnbuckle threads and .169″ (4.3mm) ball studs and replace Losi #A-6005. They will not work with 4.8mm balls.
