Piston Pro X Extension

Do you have a 2-bike Piston Pro X but need more capacity for yourself, your friends, or your family? Upgrade to carry 3 or 4 bikes with the Piston Pro X 1-Bike or 2-Bike Add-Ons. Engineered for seamless expansion, these Add-Ons install in a matter of minutes (the current record is 44 seconds). Simply slide the Add-On into place, connect the pre-wired male-to-female QuickConnect™ wiring, and you're ready to roll. Add-Ons work specifically with the dedicated 2" hitch only.

Loading the Piston Pro X 3-bike or 4-bike hitch rack is effortless, even with one hand. Just push the OneTap™ Piston levers, and the cradle arms automatically open, ready for your bikes.

The FastFit™ Wheel Chock feature lets you adjust the rack on the fly to fit 18” to 29” wheels in seconds, with no tools required. These Add-Ons are engineered specifically for a dedicated 2” hitch and maintain all the same outstanding features as the 2-bike Piston Pro X hitch rack.

With features like no-frame contact, all-metal construction, semi-integrated cable locks, and premium materials such as Genuine Kashima coated struts and Tiger Drylac® powder coat, Piston Pro X Add-Ons are built to perform flawlessly for years while turning heads everywhere you go.

For heavier e-bikes, the 3-bike rack can support up to 50 lbs per tray, and the 4-bike rack supports up to 40 lbs per tray. Pair with our e-bike ramp for effortless loading and unloading. Expand your vehicle's carrying capacity—and your circle of adventure buddies—with the Piston Pro X Add-Ons.
