Description
Some projects demand a little more adjustment.
RPM Long Rod Ends deliver the same legendary strength and precision as our Heavy Duty versions while adding a longer threaded section for increased adjustment range. Whether you’re dialing in suspension geometry, fabricating custom steering links, or designing a one-of-a-kind linkage system, these rod ends provide the flexibility to make it happen.
Like every RPM rod end, we reinforce the high-stress areas, mold them from our trademark engineering-grade nylon and hold them to exceptionally tight tolerances for smooth, consistent operation.
They also include an oversized hex for easy installation along with a small recess that allows steeper operating angles without binding. The result is a rod end that moves freely through a wider range of motion while maintaining the strength and durability RPM customers have trusted for more than 30 years.
From R/C racing and bashing to robotics, engineering prototypes and custom mechanical projects, RPM Long Rod Ends continue to prove that great design has no limits.
More adjustment. Same legendary durability.
Tech Notes: RPM 4-40 rod ends are designed for 4-40 (or 3mm) turnbuckle threads and 0.169″ (4.3mm) ball studs and replace Losi #A-6005. They will not work with 0.189″ (4.8mm) balls.
