Quick Answers to Common Questions

Do I really need lift supports for my truck bed cover?

Yes, especially if your cover is over 40 pounds or you use it frequently. Lift supports prevent strain, reduce wear, and make operation safer and easier.

Can I install lift supports myself?

Absolutely. Most kits take under 30 minutes to install with basic tools and no mechanical expertise required.

Will lift supports work with any type of cover?

Many universal kits fit tri-fold, retractable, and folding covers, but always check compatibility with your specific model and truck.

How long do lift supports last?

With proper use, high-quality gas-charged supports can last 5–10 years or 50,000+ cycles—far longer than cheaper alternatives.

Are lift supports weatherproof?

Yes, most are designed to resist moisture, dust, and temperature extremes. Look for models with sealed seals and corrosion-resistant coatings.

What Are Truck Bed Cover Lift Supports?

At their core, truck bed cover lift supports are gas-charged struts—similar to those used in car hoods or hat racks—that attach between the truck bed and the cover. When installed correctly, they hold the cover in place at any angle, from fully closed to fully open, without needing to be manually held up. This means no more wrestling with heavy covers, especially when you’re carrying bulky items or working alone.

These supports use compressed nitrogen gas and a piston system to create smooth, consistent force. As you open the cover, the gas expands, providing lift assistance. When you close it, the piston retracts gently, preventing slamming. Most modern supports are designed to last for thousands of cycles—think hundreds of thousands of open-and-close motions—so they’re built to endure real-world use.

There are two main types: single-stage and multi-stage. Single-stage supports offer a steady level of lift throughout the entire range of motion. Multi-stage (or dual-tension) models provide extra lift near the top of the arc, which some users prefer for heavier covers or taller bed rails. Both types are effective, but your choice may depend on your specific cover weight and personal preference.

Why You Need Truck Bed Cover Lift Supports

Let’s talk practicality. If you drive a full-size truck—like a Ford F-150, Chevy Silverado, or Ram 1500—the average hard or soft cover weighs anywhere from 40 to 80 pounds. That’s a lot to lift repeatedly, especially if you’re doing it daily. Without lift supports, you’re either holding the cover up yourself (which gets tiring fast) or risking damage from slamming it shut.

Beyond convenience, lift supports protect both your cover and your truck bed. Constant manual lifting leads to wear on hinges, latches, and the cover itself. Over time, this can result in misalignment, broken clips, or even structural fatigue. By taking the strain off these components, lift supports extend the lifespan of your entire system.

They also improve safety. Imagine trying to open a heavy cover with one hand while balancing a ladder or a cooler. With lift supports, you can operate the cover safely with just one hand—freeing up the other for whatever else you need to carry. Plus, since the cover stays in position once opened, there’s less chance of it slipping or falling unexpectedly.

Another often-overlooked benefit? Weather resistance. Many covers are made of materials like vinyl, fiberglass, or aluminum, all of which degrade faster when exposed to repeated stress or improper handling. Lift supports help maintain proper tension and alignment, reducing the risk of leaks or warping in rainy or snowy conditions.

Types of Truck Bed Cover Lift Supports

Not all lift supports are created equal. Understanding the different types will help you choose the best fit for your setup.

Gas-Charged Struts vs. Spring-Assisted Models

The vast majority of modern lift supports use gas-charged technology. These are reliable, low-maintenance, and provide smooth, consistent force. They’re also quieter than spring-based systems, which can squeak or rattle over time.

Spring-assisted supports are older-style mechanisms that rely on coiled springs. While cheaper upfront, they tend to lose tension over time and may require periodic adjustments or replacements. For long-term value, gas-charged models are generally the smarter choice.

Single-Stage vs. Multi-Stage Supports

Single-stage supports apply the same amount of lift across the entire arc of motion. This works well for lighter covers or trucks with lower bed rails.

Multi-stage (or dual-stage) supports deliver more force as the cover approaches the open position. This gives you extra leverage when lifting the cover high enough to access tall items in the bed. If you frequently transport kayaks, coolers, or tools, multi-stage might be worth the slight extra cost.

OEM vs. Aftermarket Options

Some manufacturers include lift supports as factory equipment—especially on premium tonneau covers like those from Extang, BakBox, or TruXedo. If yours came with them, great! But many budget-friendly covers ship without them.

Aftermarket kits are widely available and typically more affordable than buying directly from the cover manufacturer. Brands like Rugged Liner, Tonno Pro, and Lund offer universal-fit kits that work with most popular cover types.

Adjustable vs. Fixed-Length Supports

Most aftermarket supports come in fixed lengths, meaning you select based on your truck’s bed length (e.g., 6.5 ft, 8 ft). Some high-end models offer adjustable rods, allowing fine-tuning for perfect fitment.

For most DIY installers, fixed-length supports are simpler and sufficient. Just measure your cover’s mounting points before ordering.

How to Choose the Right Lift Supports for Your Truck

Picking the wrong lift support isn’t just frustrating—it can lead to poor performance or even damage your cover. Follow these steps to get it right:

1. Know Your Cover Weight

Check your tonneau cover’s specifications. Manufacturers usually list the approximate weight. If not, a bathroom scale can help: weigh an empty cover before installation.

Lift supports are rated by force output (measured in pounds). For example, a common rating is “20 lbs.” This doesn’t mean the cover weighs 20 lbs—it means the strut can lift that much. Most truck bed covers need supports rated between 18 and 26 lbs per side, depending on size and material.

2. Match to Your Bed Length

Supports come in standard lengths:
– 48″ for compact trucks
– 60″ for mid-size beds
– 72″ for full-size trucks

Measure from the hinge point on the cab side to the latch point on the tailgate side. Add a few inches for overlap to ensure proper reach.

3. Consider Your Cover Type

Different covers have different mounting styles:
– Tri-fold covers mount at three points along the bed rail.
– Retractables often use a single central mount.
– Hard folding covers may have multiple attachment spots.

Make sure the support kit includes compatible brackets or adapters for your specific cover model.

4. Check Compatibility Charts

Reputable brands publish compatibility charts on their websites. Input your truck year, make, model, and bed length to find exact matches. For example, a 2020 Ford F-150 with a 6.5-foot bed will have different requirements than a 2015 Toyota Tacoma with a short bed.

5. Don’t Forget Climate

Lift supports contain pressurized gas, which can be affected by extreme temperatures. In very cold climates, gas pressure drops slightly, reducing lift power. In hot environments, nothing major happens—but always choose quality brands that test their products across temperature ranges.

Installation Guide: Installing Truck Bed Cover Lift Supports

You don’t need to be a mechanic to install lift supports. With basic tools and patience, most people can do it in under an hour. Here’s how:

Tools You’ll Need

– Socket wrench or ratchet set
– Screwdrivers (Phillips and flathead)
– Measuring tape
– Pliers (optional)
– Lubricant (light machine oil or silicone spray)

Step-by-Step Process

1. Remove the Cover: Open the cover fully and secure it using tie-down straps or have someone hold it. Disconnect any electrical connections if your cover has lights or sensors.
2. Locate Mounting Points: Identify where the old supports were attached (if replacing) or find equivalent spots on the bed rail and cover frame. Clean the area thoroughly.
3. Attach Brackets: Install the provided brackets onto the cover and truck bed using the included hardware. Tighten securely but don’t overtighten—this can warp metal.
4. Install New Supports: Connect each support to its bracket. Most kits include quick-connect fittings that click into place. Give them a gentle tug to confirm they’re locked.
5. Test the Operation: Slowly open and close the cover several times to ensure smooth movement and proper alignment.
6. Lubricate Moving Parts: Apply a light coat of lubricant to hinges and pivot points to reduce friction and noise.
7. Reinstall Electrical Components: If applicable, reconnect lights, switches, or control modules.

Pro Tip: Always install supports on both sides for balanced lift. Skipping one side causes uneven pressure and premature wear.

Maintenance Tips for Longevity

Once installed, lift supports rarely need maintenance—but a little care goes a long way:

– **Inspect annually** for signs of leakage (oil residue around seals), rust, or loose bolts.
– **Avoid overloading** your cover beyond its rated capacity. Extra cargo shifts weight and can stress the supports.
– **Keep moving parts clean.** Dirt and debris can interfere with smooth operation.
– **Don’t force the cover.** If it feels stiff, double-check alignment—not the supports themselves.

Most reputable brands offer limited lifetime warranties, so save your receipt just in case.

Frequently Asked Questions

What weight rating should I choose for my lift supports?

Choose supports rated slightly above your cover’s actual weight—typically 20–26 lbs per side for standard truck bed covers.

Can I replace only one lift support?

No. Always replace both sides simultaneously to maintain balance and prevent uneven stress on the cover mechanism.

Do lift supports void my truck warranty?

Generally no—adding accessories like lift supports doesn’t affect most factory warranties as long as installation is done properly.

Are adjustable lift supports worth the extra cost?

Only if you have a non-standard cover or bed length. For most trucks, fixed-length supports work perfectly fine and are more affordable.

How do I know if my lift supports are leaking?

Look for oily residue around the piston rod or notice the cover dropping slowly when open—signs of internal seal failure.

Can I use lift supports on a soft roll-up tonneau cover?

Yes, but only if your cover has rigid end caps or mounting brackets. Pure vinyl roll-ups may not have sturdy enough attachment points.
