How TruXedo’s Elevate Rack System Works with Your Tonneau Cover Without Removing It
Most truck owners assume they need to choose between a tonneau cover and a rack system — that you either get weather protection or cargo capacity, but not both. We built the Elevate rack to eliminate that compromise.
Our adjustable riser system mounts the rack frame high enough to clear any tonneau cover’s side rails while still distributing weight across the bed properly. The rack stays installed full-time, you operate your cover normally underneath it, and the whole setup takes about thirty minutes to bolt together with basic hand tools.
Why the Adjustable Riser Design Matters
Traditional bed racks clamp directly to the bed rails, which means any tonneau cover installed there creates a physical conflict — the rack’s mounting feet land exactly where the cover’s side rails sit. Our Elevate system uses vertical risers that lift the rack’s crossbar supports 3-6 inches above the bed depending on which height setting you choose.
That clearance lets the TruXedo Platinum Tonneau Cover operate completely independently underneath — you roll it open or closed without ever touching the rack hardware. The risers bolt through the existing stake pocket holes, so you’re not drilling into the bed or modifying anything permanent.
The rack frame itself spans from riser to riser above the cover, creating a stable platform for kayaks, ladders, or lumber while the cover below still seals against weather and keeps smaller gear secure.
Weight Distribution Across Both Systems
The key engineering challenge was making sure the rack’s load doesn’t concentrate stress on the tonneau rails below it. Each riser distributes weight vertically down through the bed’s factory stake pockets — the same reinforced mounting points truck manufacturers design for this exact purpose — rather than pressing laterally against the cover’s aluminum extrusions.
How Clearance Settings Work with Different Cover Styles
The Elevate rack ships with three riser height positions: low (3 inches), mid (4.5 inches), and high (6 inches). You pick the setting based on which tonneau profile you’re running and how much vertical space you need for the cargo you typically haul.
Low-profile soft roll-ups usually need only the 3-inch setting because their rails sit nearly flush with the bed. Hard folding covers with thicker panel stacks when opened might need the mid setting to avoid contact when the rack frame swings into position. Retractable covers with canister housings at the cab end occasionally require the high setting if you’re mounting a front crossbar directly over that bulkier section.
Testing Fit Before Final Installation
We include an adjustable test bracket in the kit so you can verify clearance before drilling anything permanent. Set the bracket to your chosen height, position it over the cover with the cover both open and closed, and confirm there’s at least a half-inch gap in both positions. If the cover’s top surface touches the bracket in either state, step up one height level and test again.
What Actually Limits Load Capacity in a Combined Setup
The rack itself is rated to 500 pounds evenly distributed, but that number assumes you’re mounting to a bare bed with full structural contact. Adding a tonneau cover underneath doesn’t change the rack’s frame strength, but it does introduce a second component with its own lower weight tolerance — most tonneau covers max out around 300-400 pounds of snow load or stacked cargo pressing down on their panels.
The practical limit for a truck bed rack tonneau combination comes down to whichever component is weaker. If you’re hauling something heavy enough to approach the rack’s 500-pound rating, that same weight is also pressing down through the rack’s feet onto the bed rails, and those rails now have a tonneau cover sandwiched between them and the bed floor. The cover’s rails aren’t designed to bear concentrated point loads from above — they’re engineered to resist lifting and seal against the bed, not to act as structural beams supporting hundreds of pounds.
Safe Loading Practice for Dual Systems
Keep the majority of your cargo weight on the rack itself — kayaks, roof boxes, or lumber that spans between crossbars without sagging down to touch the cover below. Avoid stacking anything directly on the closed tonneau surface when the rack is installed above it, because that creates a crushing load the cover’s thin aluminum or vinyl wasn’t built to handle. For extremely heavy items like a rooftop tent or multiple loaded jerry cans, consider temporarily removing the cover and running the rack alone, which restores the full 500-pound capacity. Research from the American Society for Testing and Materials on truck bed loading mechanics confirms that composite systems should be rated to the lowest-capacity component, not the sum of both.
Installation Sequence and Common Mistakes to Avoid
Start with the tonneau cover already installed and properly adjusted — you want it rolling or folding smoothly with even gaps on both sides before the rack goes on. If the cover’s alignment is off, adding the rack won’t fix it and will likely make diagnosing the original issue harder later.
Mount the front riser pair first, closest to the cab, and hand-tighten the bolts through the stake pockets without fully torquing them yet. Slide the front crossbar into those risers, then move to the rear riser pair and repeat the process. With all four risers positioned and the crossbars loosely in place, open and close the tonneau cover a few times to confirm nothing binds or rubs.
The One Step People Skip That Causes Problems Later
Once you’ve verified clearance, torque the riser bolts in a cross pattern — front left, rear right, front right, rear left — to 35 ft-lbs as specified in the manual. Skipping this step or just tightening them “snug by feel” lets the rack shift slightly under load, which eventually wears the stake pocket holes into ovals and ruins the bed’s resale value. If you’re also adding truck bed lighting for night access, run those wires before final torque so you don’t have to loosen everything again to route cables later.
When to Consider the Elevate CS Compact Rack Instead
The full Elevate system with adjustable risers works best if you regularly haul long items — 8-foot lumber, multiple kayaks, or anything that benefits from the maximum crossbar span. But if your typical cargo is shorter and you want the simplest possible installation, the Elevate CS Rack uses a fixed low-profile design that sits closer to the bed and requires fewer adjustment steps during setup.
The CS model trades some vertical clearance for faster install time — it’s a better match if you’re running a very low soft roll-up and mostly carrying bike mounts or a small cargo box. The adjustable version this guide focuses on handles a wider range of cover styles and taller cargo, but takes an extra fifteen minutes to dial in the riser height correctly.
For overlanding setups where you might add camper shells or toppers seasonally, the adjustable Elevate’s height flexibility means you can reconfigure it for whatever bed configuration you’re running that month without buying a second rack.
Making the Combined System Work Long-Term
The practical advantage of running a rack over your tonneau cover isn’t just about saving the hassle of swapping systems back and forth — it’s about actually using your truck bed the way you need to on any given day without planning ahead. Throw a kayak up top in the morning, roll the cover closed to secure your tools underneath, and you’ve got both cargo types handled in the same load.
Check the riser bolts for tightness every few months, especially if you regularly drive on rough roads or haul near the rack’s weight limit. The stake pocket threads can work loose over time, and catching that early with a quick torque check prevents bigger issues later. For detailed guidance on other bed accessories that integrate with tonneau systems, Magellan covers rack and storage combinations across multiple truck platforms.
Beyond the mechanical installation, the real test of whether this setup works for you comes down to whether the specific cargo you haul most often actually benefits from having both systems active at once. If you find yourself only using the rack a few times a year, it might make more sense to keep it in the garage and install it only when needed — but if you’re constantly juggling between covered storage and tall cargo, the adjustable Elevate system eliminates that choice entirely.
Common Questions About Running a Rack Over Your Cover
Yes, both drop-in and spray-in liners are compatible. The riser bolts are long enough to pass through the liner material and still reach the stake pocket threads underneath.
If you have a thick drop-in liner with raised stake pocket covers, you may need to trim those plastic caps slightly so the riser feet sit flush against the bed rail. Spray liners usually add less than an eighth-inch thickness and require no modification.
The rack’s crossbars add roughly the same aerodynamic drag as a loaded roof rack on an SUV — expect a 1-2 MPG reduction at highway speeds if you’re running the rack empty. The tonneau cover itself typically improves fuel economy by 5-10% compared to an open bed, so the net effect of both together is still better than a bare open bed with no cover.
Loading tall cargo on the rack obviously increases drag further. A kayak or roof box will cost you another 2-3 MPG depending on size and speed.
The risers unbolt in about five minutes using a socket wrench, and removing them leaves only the factory stake pocket holes visible — no permanent modification to fix or hide. Store the rack hardware in a covered area to prevent the aluminum crossbars from oxidizing.
The tonneau cover operates exactly as it did before the rack was installed, since the cover’s mounting hardware was never disturbed during rack installation. Most owners who remove the rack seasonally mark the front and rear riser positions with a paint pen so reinstallation takes even less time.
Yes, because the Elevate rack’s riser design keeps the tailgate area completely clear. Standard bed extenders that insert into the tailgate’s receiver tube work normally, and flip-down tailgate steps mount and operate without interference.
The only accessory that sometimes conflicts is an over-the-tailgate bike rack that clamps to the top edge of the tailgate itself — if that rack’s upright support arms are tall enough, they can contact the rear crossbar when the tailgate swings down. Hitch-mounted bike racks avoid that issue entirely.
Measure the tallest point of your cover when it’s fully closed — usually the top of the side rail extrusion or the peak of a hard folding panel. Add a half-inch minimum clearance to that height, and pick the Elevate riser setting that puts the crossbar at least that high above the bed floor.
If your measurement falls between two riser settings, go with the taller one. The extra inch of height costs you nothing in terms of load capacity or stability, and it eliminates any chance of contact when the truck bed flexes over rough roads.
You need a 1/2-inch socket wrench or ratchet for the riser bolts, a torque wrench that reads up to 50 ft-lbs, and a tape measure for checking clearances. A second person makes positioning the crossbars easier but isn’t required — the components are light enough to manage solo.
If your bed has a spray-in liner, keep a utility knife handy in case you need to trim any overspray around the stake pocket holes. Some installers also use a felt-tip marker to label which riser goes where, but the parts are symmetrical enough that mix-ups rarely cause problems.
