Description
For more than three decades, RPM Heavy Duty Rod Ends have quietly become one of those products builders keep coming back for. They aren’t flashy. They simply work, and they’ve been proving it since the early 1990s.
When a linkage fails, everything stops.
That’s why builders, racers, engineers and hobbyists have trusted RPM Rod Ends for more than 30 years. From high-performance R/C vehicles to robotics, custom mechanisms, and even full-size automotive projects, RPM rod ends have earned a reputation for strength, precision and long-lasting reliability.
We reinforce every rod end in the areas that experience the highest loads while maintaining the tight manufacturing tolerances RPM has become known for. Molded from our trademark blend of engineering-grade nylons, they resist cracking, reduce flex and hold up under punishment that leaves ordinary rod ends behind.
Whether you’re replacing worn steering links, building custom camber links, designing a robot, or creating a completely new linkage system, RPM Heavy Duty Rod Ends deliver smooth operation and dependable performance project after project.
For over three decades, these rod ends have remained a staple of the RPM product line for one simple reason, they work.
Build it once. Trust it every time.
Tech Notes: RPM 4-40 rod ends are designed for 4-40 (or 3mm) turnbuckle threads and 0.169″ (4.3mm) ball studs. They will not work with 0.189″ (4.8mm) balls.
