Truck Bed Cap
Storage Shelf System
Your gear. Organized. Off the floor.
Bolt-on interior shelf system built for TKMAUTO aluminum truck bed caps on mid-size pickups.
Stop digging through a pile. Mount your tools, gear, and supplies on the side wall — right where you need them, every time.
Sold Per Side — Please Select Your Side
This shelf system is sold individually by side. Please select Left Side (Driver Side) or Right Side (Passenger Side) from the option above before adding to cart.
Need both sides? Add your first side to cart, then come back to this page, select the other side, and add it to cart again. Both will ship together.
Features
Direct Bolt-On Fit
Designed to mount onto the pre-drilled interior side wall rails of TKMAUTO aluminum truck bed caps. No drilling, no modifications — bolts in and locks down in minutes.
Heavy-Duty Aluminum Construction
6000-series aluminum shelf panels — same material as the cap itself. Lightweight, corrosion-resistant, and built to handle tools, gear, and supplies day after day.
Modular & Expandable
Configure single or double-sided shelving. Add dividers, hooks, or tool holders as needed. Expand your setup without replacing the whole system.
Floor Space Stays Clear
Shelves mount high on the side walls — your floor space stays open for large cargo, coolers, or gear bags. Organized above, open below.
Secure Load. No Rattle.
Rubber-lined shelf edges and locking brackets keep everything in place on rough roads. Your tools won't shift — mile one or mile one thousand.

FAQ
Which trucks is this compatible with?
Compatible with all TKMAUTO aluminum truck bed caps for mid-size pickups: Toyota Tacoma, Chevrolet Colorado, GMC Canyon, and Nissan Frontier.
Do I need to drill into my cap?
No. The shelf system bolts directly onto the existing pre-drilled interior mounting rails — no new holes required.
Can I use shelves on both sides at the same time?
Yes. The system supports single or double-sided configuration depending on your storage needs.
What if I need shelves for both sides?
Simply add each side to your cart separately. Select "Left Side (Driver Side)", add to cart, then return to this page, select "Right Side (Passenger Side)", and add to cart again. Both items will ship together.
Will my gear slide around on rough roads?
No. Rubber-lined shelf edges and locking brackets keep everything secure — even on unpaved roads.
Can I add more shelves or accessories later?
Yes. The modular design lets you add dividers, hooks, or additional shelf panels without replacing the base system.

Questions
Frequently Asked
How long does installation take?
Most customers complete the install in about 1–2 hours with two people. No drilling is required — the cap secures to your existing bed rail holes with the included mounting clamps. An install guide is in the box.
Does it come with side windows, or is it solid?
We build both versions on the same 6061-T6 aluminum shell — same load rating, same bolt-on install. The difference is only the side panels:
Windows — tempered sliding glass on the driver and passenger sides. Better for overlanding, camping, pets, or any time you want airflow and outward visibility.
Solid — fully enclosed aluminum panels. Better for job-site tool security or gear you want out of sight and keyed-locked.
Will it fit my truck?
This cap is cut for the specific year, make, model, and bed length listed in the fitment box at the top of the page. If your truck matches that spec, the cap is engineered to bolt right on. Short-bed and long-bed versions are not interchangeable.
Will the aluminum rust or the powder coat fade?
The shell is 6061-T6 aluminum — corrosion resistance is inherent to the material, so the structure won't rust. The exterior is finished in powder-coated black for UV protection. Even if the powder-coat gets scuffed at a job site, the aluminum underneath stays sound. If you ever have a structural concern, contact us at info@tkmauto.com and we'll work with you directly.
How does shipping work?
Free freight shipping in the continental US, from our California warehouse via LTL carrier. Delivery requires a signature; the carrier will schedule a window once it reaches your local terminal. A phone number is required at checkout so the freight carrier can reach you to schedule delivery.
Built with 6061-T6 aluminum shell and stainless steel hardware. If you ever have a structural concern with your cap, contact us at info@tkmauto.com and our California team will work with you directly.
