Features to know about
Handles Long Loads with Ease: Over-Cab Cantilever Support
The built-in cantilever extension gives you 32" of extra rack length that reaches over the cab. That extra space makes hauling long boards, ladders, or conduit simple and secure. The cantilever is built from the same 6000-series aluminum as the rest of the rack, so it carries up to 1,000 lbs and matches the same streamlined, aerodynamic design.
Keeps Gear Secure but Easy to Access: Sliding T-Track System
The rack uprights slide the full length of your truck bed on integrated T-track base rails. You can move the bars together for better aerodynamics and bed access or spread them apart for longer cargo. Quick-release clamping knobs make repositioning fast—just loosen, slide, and tighten. When you need the bed clear, the whole rack lifts off the tracks in minutes.
Strong, Light, and Rustproof: 6000-Series Aluminum Construction
Every piece—from the base rails to the crossbars—is made from lightweight, rustproof aluminum. The internal web structure adds strength without extra weight, and the dual-stage powder coat finish (an e-coat followed by a clear coat) protects against corrosion, scratches, and scuffs. With a carrying capacity of 1,250 lbs, you get the strength of a work rack without the heavy steel drawbacks.
Quiet Ride and Clean Look: Aerodynamic Crossbars with Airfoil Strips
Elliptical crossbars minimize drag and noise while you drive. Built-in airfoil trip strips prevent wind from whistling through the bar slots, keeping your ride quiet and more fuel-efficient. The smooth, low-profile shape also gives the rack a neat, finished look that stays clean after miles on the road.
Ready for Real Workloads: Load Stops and Side Cleats Included
The rack comes with 4 heavy-duty aluminum load stops that slide in the crossbar channels to hold cargo in place. Each has a built-in loop for straps, and they lock down with a twist of the knob. Four side cleats mount on the uprights for extra tie-down points, giving you multiple ways to secure anything from ladders to lumber.

See what our Experts say about this Thule Ladder Racks
- Truck Bed Roof Rack System For A 2012 Nissan FrontierThe best solution that you have on your 2012 Nissan Frontier is # # Y01152-5868, but you will have to remove your tonneau cover. All ladder racks need to sit on the inside of the rails of the bed of your truck besides the Thule TracRac SR # TH43001XT-603EX which may interfere with your tonneau cover if it sits on the top of your bed rails. If you have a roll up tonneau cover that sits on the inside of your rails like this one # BAK38ZR you could use the TracRac SR, but it is at the height...

This rack is confirmed to fit the Crew Cab model with the 5' foot bed and Utili-Track System. This rack has the requested cantilever addition that will go over the top of your cab. It is made of lightweight aluminum and then powder coated for extra protection. This system has a 1,250 lbs capacity which is reduced to 1,000 lbs only on the portion over...
view full answer... - Is There A Ladder Rack W/ Cantilever That Fits My 2022 Toyota Tundra I do have a ladder rack option for you with a cantilever, but it will not be the Thule TracRac SR, part # TH43001XT-603EX. In fact, Thule does not offer a fit for your 2022 Toyota Tundra. The Erickson Over-The-Cab Truck Bed Ladder Rack - Steel - 1,000 lbs, part # EM07707, will fit your vehicle. It has a maximum weight limit of 1,000 lb. I have included a product description link and a video review link below.

Since your tonneau cover mounts inside the bed rails you can use the Thule TracRac SR # TH43001XT-603 or # TH43001XT-603EX (with the over-the-cab extension) as it mounts on top of the bed rails. The TracRac SR is one of the best ladder racks that we have to offer. It has a weight rating of 1,250 lbs and installs on rails which allow you to move the crossbars to varying...
view full answer... - Ladder Rack Fits for 2008 Nissan Frontier Crew Cab 5-foot Bed and Utili-Track System We have several choices in a ladder rack for your 2008 Nissan Frontier Crew Cab with 5-foot bed and the Utili-Track system and these include racks from Erickson. You can see all of these on the linked page. The particular rack model # EM07706 that you referenced does not fit your model year truck but you can use Erickson aluminum rack # EM07705 (shown in the linked video) or their black rack with cab extension # EM07707. Both of these are rated for 800-lbs. If you want the highest weight...
view full answer... - Best BAK Tonneau Cover and TracRac Ladder Rack Combination on 2016 Nissan FrontierThe TracRac SR # TH43001XT-600 you mentioned will not fit the 5 foot bed 2016 Nissan Frontier, it's for the 6 foot bed. For the 5 foot bed you'll need # TH43001XT-603EX. The TracRac SR is not likely a fit with the BAKFlip F1 BAK72506 for a couple of reasons. For one when opening the panels of the BAKFlip you will most likely come into contact with the uprights of the TracRac. It's possible you could slide the ladder rack to avoid this. Another problem is that the tracks of the TracRac...
