UnderCover Elite LX One-Piece Tonneau Cover for 2024-2026 Chevrolet Colorado (5'2" Bed)

For the Chevrolet Colorado running the 5'2" box, this is the Elite LX that fits it, in your truck's own paint code or bare for your body shop. What separates the Elite LX from the rest of the range is the factory paint and what sits under it. The structure is a single sheet of molded ABS polymer, hinged at the bulkhead and raised by gas struts, and UnderCover publishes 500 lb evenly distributed for it closed, more than it claims for anything else it currently sells. Security is a key lock plus an integrated thumb lock on a one-hand rotating handle, and because the lid overlaps the tailgate, one turn secures the whole bed. The headliner underneath is carpeted and carries an LED light. UnderCover sprays this cover in 5 factory paint codes for this truck, and also supplies it unpainted for a body shop to finish. Two people set the lid onto the Chevrolet Colorado, and after that the brackets stay put whether the lid is on or off. The part numbers are UC1278L in a factory paint code and UC1278S unpainted, both built for the 2024-2026 Chevrolet Colorado with the 5'2" (61.7") bed.

About the color list and the photographs. The codes in the dropdown are every factory code UnderCover sprays this cover in, pooled across all the model years the cover fits. The list does not narrow itself when you pick a year, and factory paint offerings change from year to year, so read the code off your driver's door jamb sticker and match it exactly before you order. The photographs on this page show one painted lid in one color and stand for the product, not for the code you choose.

Features

Sprayed to Your Truck's Own Code
This is the tier you buy for the finish. UnderCover sprays the lid at its own paint line to the OEM code you pick, so the closed truck reads as one color from the cab to the back of the tailgate instead of a black panel dropped onto a painted body. UnderCover does not guarantee a 100% match, and says so in its printed warranty: paint varies from one truck to the next with age and sun, and some variance is normal.

Carpeted Underside, Not Bare Plastic
Raise the lid and the underside is a gray carpeted headliner with the Elite LX badge embroidered into it, rather than the bare textured plastic the cheaper one-piece covers show. It is the difference you notice every time the lid is open, and it is the quickest way to tell an Elite LX from an Elite at a glance.

Rated 500 lb Evenly Distributed
UnderCover rates the closed Elite LX at 500 lb evenly distributed, the highest figure it publishes for anything in its current range. Evenly distributed is doing real work in that sentence: it means weight spread across the lid, not a point load in one spot, and it applies to the lid closed and latched.

Key Lock and an Integrated Thumb Lock
Security runs through a key-locking latch with an integrated lock mechanism, worked from a one-hand rotating handle with a hinged cap over the cylinder. Because the lid overlaps the bed caps and the tailgate, one turn of the key secures the lid and the tailgate together, so the whole bed is behind one lock.

Covers the Bed Caps and the Tailgate
The lid sits over the bed caps and across the tailgate rather than down inside the bed rails, so the rails themselves are under cover and the closed truck presents a continuous painted surface from the bulkhead to the back of the tailgate.

Struts Up, and Off in a Minute
Two gas struts take the weight and hold the lid up while you load, with a prop rod backing them up and a lanyard pull strap for pulling the lid back down. When the load is taller than the bed the lid comes off the four-bar hinge entirely, and the brackets stay bolted to the truck while it is off.

Bolted On, Nothing Drilled
The brackets clamp and bolt to the inside of the bed, and no UnderCover installation sheet for a one-piece cover asks you to drill the truck. A plastic drop-in bedliner is the exception that does need work: it may need minor trimming so the brackets seat flat. Trim the liner and never the mounting hardware, because modified hardware voids the warranty.

The Paint Warranty Is the Point
UnderCover backs the ABS polymer structure for the life of the product and adds a lifetime paint warranty on covers it painted itself: for the life of the product the finish will not fade or peel abnormally faster than the paint on the truck it is fitted to. Gas struts and mounting hardware carry one year.

Installation

Tools: 3/8" wrench or socket and 1/2" wrench or socket · Help: Two people to set the lid on the truck

The mounting brackets bolt and clamp to the inside of the bed, the four-bar hinge on the lid drops onto the front brackets, and the struts snap onto the rear brackets by hand. Nothing is drilled into the truck.

UnderCover does not publish a vehicle-specific installation sheet for this application, so this listing prints no bracket measurement, no torque figure and no platform-specific step for it. Work from the measurements supplied with your cover.

No cutting or drilling is done to the truck itself. A plastic drop-in bedliner is a different matter: UnderCover's own sheet says a drop-in liner will need some minor trimming so the mounting brackets seat properly. A spray-in liner needs no work. Any modification is made to the liner and never to the UnderCover mounting hardware, because modified hardware voids the warranty.

Warranty, Shipping & Returns

Warranty. UnderCover's printed terms for the one-piece covers warrant the ABS polymer structure of the Elite LX to be free from defects in material and workmanship for the life of the product, and warrant the gas and hydraulic lift struts and the mounting hardware for one (1) year from the date of purchase. On top of that, covers painted at UnderCover's own factory carry the UnderCover Lifetime Paint Warranty: for the life of the product the exterior paint will not abnormally fade or peel from a material or workmanship defect faster than the paint on the truck it is fitted to. That paint term is what this tier is for, and it is explicit that covers not painted at the UnderCover factory are excluded, so an unpainted lid finished by your own body shop is covered for structure and components but not for paint. UnderCover also does not guarantee a 100% paint match. The warranty runs to the original purchaser, on the original truck, when the cover is bought from an authorized dealer, and registration and claims are handled by the manufacturer. Four conditions in the printed terms catch people out more than the rest. Do not drive with the lid in the open position and never tie it down while it is open, because that loads the front hinges and can crack them, and that damage is not treated as a manufacturer defect. When the lid is closed it should be locked with the tailgate up. Use only cleaners, waxes and products labeled safe for use on plastics, and keep insecticides and solvents off the lid. Any trimming needed to fit the brackets is done to the bedliner and never to the mounting hardware, because modifying the hardware voids the warranty. Free shipping. The Elite LX is a rigid one-piece lid in a carton a little over seven feet long, so it moves by freight rather than by parcel carrier, and it still ships free within the contiguous United States. The carrier will contact you to arrange a delivery window, and delivery is to the curb. Inspect on delivery. A long, shallow carton is the part that takes the knocks, and a painted lid shows a scuff that a black one hides, so open it and look at the finish before you sign for it. If the carton is crushed, torn or soaked, write that on the delivery paperwork and tell us the same day so we can get a replacement moving.

Returns. Unused items in their original packaging can be returned within 30 days of delivery. If an item arrives damaged, defective or wrong, return shipping is on us. See our Returns & Refunds Policy, or email support@prestigetruck.com with any question.
