RPM have announced that their most popular wheel, the Revolver, is now available in a Short Course version (2.2” – 3.0”). RPM Revolver Short Course wheels are built tough, look great and have an all-new drive system that is built to withstand some serious power. 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 stronger, which is why they’re used in full-sized driveline components. 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 it fails, a standard hex adapter will spin. 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 their industry-leading breakage warranty for unsurpassed strength and durability.
