Bed stiffeners - worth it?

[Chris_2025OR]

I've been reading around about bed stiffeners, and it generally seems like people recommend them when mounting a few hundred pounds to the bedsides.

I'm running a fiberglass shell, roof rack, awning, shovel, tool box, and 8 gallon water tank, so this setup would definitely fall under the category of "you need bed stiffeners."

So, I purchased a set. But I've done quite a few wheeling trips pre-bed stiffeners and never noticed anything that would indicate I need them.

I'm curious what people think about bed stiffeners. Has anyone ever noticed something wrong and gone "oh crap I need bed stiffeners?" Any deformation or bending? Have they made a noticeable difference in something once installed? Or is it another unnecessary accessory we're being told we need but actually don't?

Your shell stiffens the bed.

Solid question—and yeah, you're definitely not alone in wondering if bed stiffeners are truly necessary or just another “might as well” mod.


In your case—with a fiberglass shell, roof rack, awning, toolbox, and 8-gallon water tank—you're absolutely in the zone where bed flex becomes real over time, especially on washboard roads or off-camber trails. Even if you haven’t noticed flex yet, the strain adds up slowly until something shifts or cracks. A lot of people don’t catch it until their tailgate alignment gets weird or they see cracks in the bedside seam near the tail light area.


Cali Raised’s bed stiffeners (linked here if others are curious: 2024+ Tacoma Bed Channel Supports) are built to be a low-profile, bolt-in solution that braces that rear corner and keeps things tight long-term. I've run them on past builds, and while they don’t make a visible difference during a single trip, they definitely give peace of mind for loaded setups like yours.


So are they mandatory? No. But for anyone running a rig like yours, or planning a rack + RTT setup, they’re cheap insurance—especially when trail damage can get expensive fast.


Also… they make a decent mounting spot for extra lights or antennas down the line. Just saying

Thanks for your input! Exactly the kind of insight I was looking for.
