MOS UpLift™

MOS UpLift™ — One System, Countless Uses.
The MOS UpLift™ is a multi-sport, lift-assisted system designed to make loading and unloading your gear easier and safer. Installed on your car’s roof rack crossbars or on a van’s rear-door rack, it lowers your equipment by 2 feet (61 cm) for quick, ergonomic access and assists up to 75% of the load back up thanks to its gas springs.
It works with the racks you already own or can purchase on the market — bike racks of all kinds, kayak, canoe, and paddleboard cradles, roof boxes, and ski racks. With its shape, the MOS UpLift™ can even function as a cradle on its own.
Always ensure that the total load stays within the 125 lb (56 kg) capacity of the MOS UpLift™, the limits of your racks (bike rack, roof rack crossbars, van rear rack, cargo carrier, etc.), and your vehicle manufacturer’s specifications.

I purchased the MOS lift to assist me in getting my Delta tandem kayak onto my pickup truck. I am quite pleased with the assistance the lift provided in making the heavy kayak much more manageable.
Super
J'utilise le MOS Uplift depuis le début de l'été et j'adore le produit. La commodité d'avoir facilement accès à mes supports à vélo est un luxe dont je ne me passerait plus (surtout après une grosse sortie!). Le design est soigné et l'efficacité du système impressionnante. De l'installation jusqu'à aujourd'hui, je n'ai que des bons commentaires sur le Uplift. Merci à l'équipe de MOS pour ce beau produit local, durable et pertinent!
The lift assist does NOTHING for the final 5 inches !! I bought this because I have physical challenges and can't get my kayak onto my car's roof. If I wasn't 6ft tall and able to push the kayak up the last 5inches with my HEAD!!...I STILL wouldn't be able to get my kayak up w this lift!
Also, the entire instruction manual is in French. So no help.
Hi Mr. Schnell,
We are very sorry to hear that the product didn’t meet your expectations, and we truly appreciate you taking the time to share your feedback.
Your satisfaction is very important to us. To better understand the situation and find a solution, could you please send us a few photos of your setup while lifting your kayak to support@mosracks.com? If possible, a short video would also be very helpful.
Regarding the lift assist. On the way down, the system is designed to bring the kayak close to the loading position, reducing the effort required. On the way up, a small final horizontal push is necessary to bring the kayak back into the locked final position. Depending on the vehicle height and kayak weight, this final step may feel a bit harder.
That said, the system was designed to ensure a comfortable loading experience overall. Since the 5-inch gap you mentioned seems more than expected, we’d like to better understand your setup (vehicle make/model, crossbar type, kayak length/weight) to see if we can troubleshoot and possibly adjust your unit for easier use.
Regarding the manual. The user manual provided in the box is fully bilingual (French/English) and contains all assembly and installation instructions. There is no French-only version of the installation manual. However, you may have found a product presentation guide online that exists in French only. Please note this is not the installation manual, it highlights the features of the MOS UpLift only.
If there was no bilingual user manual in your box, our apologies for this. Please send un an email to support@mosracks.com and we’d be happy to send you a PDF copy of the bilingual user manual. We will also share a short video of a team member using the MOS UpLift so you can compare your experience with the intended operation.
Once we receive your photos/video, we’ll be able to provide tailored recommendations to make loading your kayak easier and more comfortable.
Thank you again for allowing us the opportunity to make this right.
Warm regards,
The MOS Team
