Retrax 2020 Chevrolet / GMC HD 6ft 9in Bed 2500/3500 RetraxONE MX Retrax 2020 Chevrolet / GMC HD 6ft 9in Bed 2500/3500 RetraxONE MX Retrax The RetraxONE MX is a premium manual retractable tonneau cover designed for dependable protection, smooth operation, and long-term durability. Featuring a one-piece aluminum-reinforced polycarbonate construction, the MX eliminates hinges, joints, and other leak-prone wear points—providing the unmatched performance that's trusted by over a million truck owners. Engineered to perform in demanding environments, the RetraxONE MX offers exceptional impact resistance and UV protection—proven in extreme temperatures ranging from -50 to 200ºF. An advanced water management system seals tightly and directs excess moisture out of the bed through integrated drain tubes, safeguarding your cargo. Everyday utility is unmatched with the RetraxONE MX—with a simple lift of the latch and press of a button, the spring-loaded handle deploys for quick, one-handed operation. Inside the rails, exclusive CoreTrax™ technology delivers reliable, maintenance-free performance with precision ball bearings and a custom track system that resists sticking, freezing, and wear. Security and flexibility are two hallmarks of the RetraxONE MX. The cover can be locked in any position along the rails, allowing you to accommodate oversized items while keeping a portion of the bed shielded against water, dirt, and prying eyes. A streamlined, low-profile design sits flush with the bed rails for a subtle appearance that won't obstruct rear visibility. The textured matte black finish adds durability without distracting from your truck's factory appearance. At the front of the bed, a compact canister with a spiral track system ensures smooth retraction while minimizing friction, scuffs, and long-term wear. Installation is quick and easy thanks to the integrated clamp-on mounting system, requiring no drilling or permanent modifications. Most installations take under an hour using basic tools. Each RetraxONE MX is proudly engineered and assembled in the USA and is backed by a 1-year warranty.Installation InstructionsThis Part Fits: Year Make Model Submodel 2020-2026 Chevrolet Silverado 2500 HD Custom 2020-2026 Chevrolet Silverado 2500 HD High Country 2020-2026 Chevrolet Silverado 2500 HD LT 2020-2026 Chevrolet Silverado 2500 HD LTZ 2020-2026 Chevrolet Silverado 2500 HD WT 2024-2026 Chevrolet Silverado 2500 HD ZR2 2020-2026 Chevrolet Silverado 3500 HD High Country 2020-2026 Chevrolet Silverado 3500 HD LT 2020-2026 Chevrolet Silverado 3500 HD LTZ 2020-2026 Chevrolet Silverado 3500 HD WT 2020-2026 GMC Sierra 2500 HD AT4 2024-2026 GMC Sierra 2500 HD AT4X 2020-2021 GMC Sierra 2500 HD Base 2020-2026 GMC Sierra 2500 HD Denali 2024-2026 GMC Sierra 2500 HD Denali Ultimate 2022-2026 GMC Sierra 2500 HD Pro 2020-2026 GMC Sierra 2500 HD SLE 2020-2026 GMC Sierra 2500 HD SLT 2020-2026 GMC Sierra 3500 HD AT4 2020-2021 GMC Sierra 3500 HD Base 2020-2026 GMC Sierra 3500 HD Denali 2024-2026 GMC Sierra 3500 HD Denali Ultimate 2022-2026 GMC Sierra 3500 HD Pro 2020-2026 GMC Sierra 3500 HD SLE 2020-2026 GMC Sierra 3500 HD SLT

Shipping Overview

What is your shipping cutoff time? 

Cutoff time for in stock items is 2PM CST for items shipping with UPS.  USPS cutoff time is 10AM CST.   If you need a product by a specific date, please call us to find out if its possible to meet your deadline before ordering. Please be aware that there may be discrepancies with shipping calculators or “in stock” status of a product. 

 

Is shipping free? 

Orders over $149 qualify for free shipping within the lower 48 United States. We will select the most economical shipping option for our free shipping option.  If you'd like expedited service, please select that option during checkout.  Unfortunately, shipping to AK/HI or International we cannot offer free shipping, due to the extra costs incurred.  

 

How long will it take to get my stuff? 

Most in stock orders will ship the same day, if ordered before our cutoff times.  Custom items will ship when they are completed, please inquire for timelines on custom items (as this will vary).  We are located centrally in the US (St Louis MO) - so most items arrive within 2-4 days to the lower 48 US.  You will receive a tracking number when your item ships, allowing you to keep track of it at all times.  

 

I am an international customer, are fees / duties included in the shipping costs?

No, these fees will need to be paid by our international customers.  

 

How can I get a quote for shipping?

Please add the item in your cart and proceed through the checkout process. The system will display all the options we offer, along with a price. 

 

Refund / Exchanges

We have a 30-day return policy on non custom items, which means you have 30 days after receiving your item to request a return. 

To be eligible for a return, your item must be in the same condition that you received it, uninstalled and in its original packaging. You’ll also need the receipt or proof of purchase. 

To start a return, you can contact us at sales@retroshop.us. If your return is accepted, we’ll send you instructions on how and where to send your package. Items sent back to us without first requesting a return will not be accepted. 

You can always contact us for any return question at sales@retroshop.us.

Damages and issues 
Please inspect your order upon reception and contact us immediately if the item is defective, damaged or if you receive the wrong item, so that we can evaluate the issue and make it right.

Restocking Fees 
On non customized (returnable items), a restocking fee of 5-15% may be held from your refund.  Some items are special ordered in for customers, and if we have to return them to our suppliers, we may have a restocking fee for doing so.  If there are any questions on the restocking amount, please email us at sales@retroshop.us.

Exceptions / non-returnable items 
Certain types of items cannot be returned, like custom products (such as special orders or personalized items).  Please get in touch if you have questions or concerns about your specific item. 

Unfortunately, we cannot accept returns on sale items or gift cards.

Exchanges 
Please contact us for any exchanges at sales@retroshop.us.

Shipping Charges
Shipping charges are not refunded.  If you selected our free shipping option, the amount we paid to ship the item to you will be deducted from your return.

Refunds 
We will notify you once we’ve received and inspected your return, and let you know if the refund was approved or not. If approved, you’ll be automatically refunded on your original payment method. Please remember it can take some time for your bank or credit card company to process and post the refund too.
