Product Details

Why we carry the Piston Pro

Most of our customers haul mountain bikes and e-bikes, and the Piston Pro handles both without touching the frame. It's the same platform as the Piston Pro X, minus the LED taillights and Kashima coating.

What makes the Piston family different

OneTap arms: tap the lever and the tire arms open on their own. Push them down until they click.
No frame contact: the arms hold the tires, so carbon frames and fresh paint stay untouched.
FastFit chocks: squeeze and slide to fit 18 to 32 in wheels, no tools.
Pedal pivot: fold the rack up or down with your foot.
Flatlock hitch cam and hitch lock: a tight, rattle-free fit in the receiver, locked.

Built to grow

The 2-inch Piston Pro takes Kuat's 1-bike and 2-bike Add-Ons, up to 4 bikes total. Capacity per bike drops as you add trays: 67 lb with 2 bikes, 50 lb with 3, 40 lb with 4. Ask our team about Add-Ons.

Piston Pro or Piston Pro X?

Same capacity and Add-Ons. The Piston Pro X adds LED taillights, Kashima-coated struts, a Galaxy Gray finish and a locking security tool. Pick the Pro X if your bikes block your van's taillights.

Getting into the back of the van

A hitch rack blocks the Sprinter's rear doors. Put the Piston Pro on a KUAT Pivot XD swing-away and the whole rack swings aside with the bikes still on.

Fitment & Compatibility

Fits: Universal, any van with a 2 in hitch receiver, incl. Mercedes Sprinter

Not compatible with: 1.25 in receivers (this listing is 2 in); bike covers; Add-Ons or adapters on RV hitches

DIY FriendlyYes, assembles in the hitch, no drilling

Drilling RequiredNo

The Piston Pro arrives in pieces: the centerbeam, two tire trays and the foot lever. Kuat recommends assembling it in the hitch. Plan on 30 minutes to an hour. Kuat's user guide shows each step.

Tips

Put the centerbeam in your hitch first. Kuat says it makes assembly much easier.
Pull the shipping security tabs out from under each OneTap lever before you use them.
Open the arms to reach the tray bolts and nuts.
Torque the M10 x 165 tray bolts to 40 to 50 Nm, never over 50 Nm. The foot lever bolt is 15 Nm.

Mistakes to avoid

Using a bike cover or rain cover. Kuat says never. The wind load can break the rack.
Leaving fenders loose. Fendered bikes need Kuat's Fender Strap Kit.
Skipping lock care. Add a drop of lube to the locks when you lube your chain.
Stacking adapters on an RV. On a chassis-mounted RV hitch, use the 2-inch 2-bike setup only, no Add-Ons, adapters or extenders, at 42 lb per bike.

How to choose a hitch bike rack for your van

1. Will it fit your hitch?

How to choose: Sprinter receivers are 2-inch. Buy the 2-inch version for full capacity and Add-On support.

2. How heavy are your bikes?

How to choose: E-bikes need a rack rated for them. The Piston Pro carries up to 67 lb per bike on the 2-bike setup.

3. How many bikes, now and later?

How to choose: If the crew might grow, pick a rack that takes Add-Ons. Per-bike capacity drops as you add trays.

4. Do you need lights?

How to choose: If bikes block your taillights, pick a rack with its own LED lights like the Piston Pro X.

5. Can you still open the rear doors?

How to choose: Add a swing-away like the Pivot XD if you need the rear doors with bikes loaded.

How the Piston Pro stacks up

Fitment: 2-inch receivers, including the Mercedes Sprinter.
Weight: 67 lb per bike with 2 bikes, e-bike ready.
Growth: up to 4 bikes with Add-Ons.
Access: pairs with the Pivot XD swing-away and the Piston E-Bike Ramp.

Will the Piston Pro fit my Mercedes Sprinter?

Yes. It fits any Sprinter with a 2-inch hitch receiver, and it's universal for any van, truck or SUV with one.

Can it carry e-bikes?

Yes. Up to 67 lb per bike on the 2-inch 2-bike setup. Add our Piston E-Bike Ramp to roll heavy bikes up instead of lifting.

What's the difference between the Piston Pro and Pro X?

Same capacity and Add-Ons. The Pro X adds LED taillights, Kashima-coated struts, a Galaxy Gray finish and a locking security tool. The Pro has no lights and a Sandy Black finish.

Can I add more bikes later?

Yes. Kuat's 1-bike and 2-bike Add-Ons take it to 3 or 4 bikes. Capacity drops to 50 lb per bike with 3 and 40 lb with 4. Reach out to our team for Add-Ons.

Can I use it on a camper van or RV?

Kuat approves the 2-inch 2-bike Piston Pro on chassis-mounted RV hitches at 42 lb per bike, with no Add-Ons, adapters or extenders. The hitch has to be chassis-mounted and within 64 in of the rear axle.

Can I open my rear doors with it on?

Partly. The pedal tilts the rack out to about 45 degrees to move the bikes away from the van, but the rear doors still won't open all the way. Pair it with the Pivot XD swing-away and the whole rack swings aside with the bikes loaded, so both doors open fully.

Can I use a bike cover?

No. Kuat says covers create enough wind load to break the rack.

Do fendered bikes fit?

Yes, with Kuat's Fender Strap Kit. Fenders can reduce fit and capacity.

Do you install products for customers?

Yes. Many SV products can be professionally installed at our San Diego shop. Reach out to our team to schedule. Email products@sandyvans.com or call 619-812-1903.

What is your shipping and return policy?
