Losi vehicles need longer shank rod ends to accommodate shorter turnbuckles. With these rod ends, you may replace your stock Losi rod ends with our superior RPM rod ends! They maintain our close tolerances over the ball cup and have the same oversized hex as the #7337 but these also include a small recess at the top of the ball to allow steeper angles without binding! RPM rod ends fit all Associated, Losi, & HPI ball-studs.
