RPM Replacement Spline Drive Adapters (Set Of 6)

The RPM “Spline Drive” system is radically different than the standard hex drive. A hex is easy to machine and easy to manufacture, which is why it is so commonly used. However, splines are tougher and Chrome Revolver SC Wheel (Slash 2wd front)stronger, which is why they’re used in full-sized driveline components. All standard hex style adapters push out and up every time rotational force is applied to the adapter, which is a huge reason why so many hex-style adapters spin. RPM Spline Drives direct the rotational force of the axle in a near perpendicular direction, making the likelihood of a spun adapter virtually non-existent!

Additionally, our Spline Drive has almost twice the amount of drive surface area versus a standard 12mm hex adapter and over 2.5 times the thickness at the most critical drive point of the adapter, the point that, if Black Revolver SC Wheelit fails, a standard hex adapter will spin.

Even 17mm hex drives don’t stand up to the RPM Spline Drive system. While a 17mm hex has marginally more surface area (.0777 sq. in. vs. .0744 sq. in.), our system still has nearly twice the thickness at that critical drive point, preventing RPM Spline Drives from spinning, yet eliminating the need for a huge and heavy 17mm adapter.

RPM Revolver Short Course wheels are sold in pairs (spline drive adapters are included in each package), available in black or chrome and backed by our industry-leading breakage warranty for unsurpassed strength and durability.
