RetraxONE MX Retractable Tonneau Cover for 2009-2026 Ram 1500 / 1500 Classic / 2500 / 3500 (6'4" Bed, with RamBox)

The RetraxONE MX is a manual retractable tonneau cover that uses a single sheet of aluminum-reinforced polycarbonate instead of slats or folding panels. The sheet rides on sealed ball bearings inside aluminum tracks and rolls into a compact canister behind the cab, so you can stop it wherever you like and lock it there with a key. With no hinges or seams for water to find, it carries up to 200 lb spread evenly across the top and wears a textured matte black finish that sits flush with the bed rails. Retrax builds it for owners who want a locking hard cover that opens with one hand and installs without drilling. Part number 60235 is the 6'4" bed application for the 2009-2026 Ram 1500 / 1500 Classic / 2500 / 3500, with RamBox.

What's Included:

• RetraxONE MX one-piece polycarbonate cover with front canister
• Aluminum side rails and tracks
• Clamps for the bed rails
• Vehicle-specific hardware kit
• Drain tubes
• Printed installation instructions

Features

Stop the Cover Anywhere
The RetraxONE MX is not limited to open or shut. Slide it to any point along the rails and lock it there, so a ladder can poke out the back while the front stays covered. Gear can also be cinched between cover and tailgate.

One Sheet of Polycarbonate
Instead of slats or folding panels, the MX uses one aluminum-reinforced polycarbonate sheet with no hinges or joints to leak. It resists impacts and UV, is tested from -50 to 200 F and holds up to 200 lb of evenly distributed weight.

Lift, Press and Pull
Opening takes one hand. Lift the latch and press the button, and a spring-loaded handle pops up so you can pull the cover back. It is key-lockable in any position along the rails, so a part-open bed can still be secured.

Seals Tight, Drains Out
A revised water management system seals the cover against the rails and sends whatever gets past the seals into integrated drain tubes that carry it out of the bed. One continuous top means no panel gaps for rain or dust.

CoreTrax Bearings and Spiral Canister
Inside the aluminum tracks, CoreTrax sealed ball bearings carry the cover with no lubrication and are built to resist jamming and freezing. At the front, a canister with a spiral-track guide winds the cover the same way every time, keeping friction and scuffing down.

Clamp-On Install in Under an Hour
The rails clamp to your factory bed rails with the vehicle-specific hardware in the box. Nothing is cut, trimmed or drilled. Retrax rates the job Level 1 and most owners finish in 60 minutes or less with basic tools.

Warranty, Shipping & Returns

Warranty. Retrax covers the RetraxONE MX with a limited warranty against defects in materials and workmanship for one year from the date of purchase, for the original buyer only and with proof of purchase possibly required. Accident damage, neglect, misuse, incorrect installation or servicing, harsh cleaners and any lubricant on the rails or sealed bearings all void it, as does towing the truck from the rear with the cover fitted or driving with cargo unsecured. Approved claims are repaired or replaced at the manufacturer's discretion after a return authorization number is issued, and shipping is at the owner's expense.

Free shipping. This item ships free to the lower 48 states. Because it is an oversized item, it ships by freight or oversized parcel and typically arrives in 3 to 7 business days.

Inspect on delivery. Please inspect the packaging before signing. If you see any damage, note it on the delivery receipt and contact us right away, and we will make it right.

About Retrax

Retrax builds retractable truck bed covers that roll into a canister at the front of the bed rather than folding or rolling up. The manual range covers the RetraxONE MX and XR, the RetraxPRO MX and XR, the Retrax IX and the RetraxPRO FRC-4000 EZ-OFF, with the XR versions and the EZ-OFF adding T-slot rails on top.

Every RetraxONE MX is engineered and assembled in the United States, and Retrax says more than a million truck owners run one of its covers. Retrax calls CoreTrax an exclusive technology: maintenance-free ball bearings in a custom track, paired with a canister built around a spiral-track guide.

Two warranty tiers separate the lineup. A RetraxONE cover, including this MX, carries a one-year limited warranty, while a RetraxPRO cover carries a limited lifetime warranty. Both are backed by product experts and a customer service team based in the USA. The MX itself is proven for impact and UV resistance from -50 to 200 F.
