Review of Thule Replacement Ladder Racks Modular Slider - TA01-42004

Video Transcript for Review of Thule Replacement Ladder Racks Modular Slider - TA01-42004

Hi there. I'm Michael with etrailer.com. Today, we're gonna take a quick look at this Thule replacement, modular slider. This is going to replace one slider for your Thule track rack or utility rack sliding ladder rack. This is going to work for the left rear or the right front. It is going to be a direct replacement from Thule.

So you can trust it is going to fit right in place of that original and slide on that track to ensure that your ladder rack is where you need it to be. You can see the angle that we have here, and the reason that this will only work for that driver's side rear or the passenger side front application but otherwise it is going to be exactly what you need because it is a direct replacement from Thule. You don't have to worry about compatibility issues or anything like that. So if that left rear or right front slider is no longer operational for you this is gonna be exactly what you need, so that you can get your ladder rack up and going again. That completes our look for today.

Again, I'm Michael with etrailer.com. Thanks for watching..

etrailer always makes hard to find items easier and cheaper. Combined with great communication, reviews and information on items, many different options and advice on alternatives topped off with amazing shipping department. This is my one stop shop for all trailer, camper and truck and tow accessories.

by: Jorge R. 03/22/2017

Very good product. The door of a garage closed when I was entering and hit the back of my tracrac g2 breaking the modular bases slider but the orders in etrailer and they were perfect thanks.

Your sales team was very helpful finding a replacement part for my TracRac rack system.

by: Brian A 11/12/2020

I never leave reviews. I shop online quite a bit but never seem to have the time. In this case however, I feel obligated to say how great I think this company is. Absolutely everything from searching product, placing an order, easy checkout options, extremely fast shipping and probably the best communication I’ve received out of any company I’ve ever used for online shopping. This online retailer sets the benchmark pretty high for all the others. I will continue to make this my first stop whenever placing a part order! The etrailer should be very proud of the company that they run!

by: Ronald 08/05/2023

Findimg part your website was easy and the part page gave good information to confirm the proper part.
Online order process was easy with good shipping information provided for yracking. Parts arrived sooner then expected.
All aspects of this purchase were great and I will use this company again.

by: doug s 07/03/2017

Im giving a bad review for 2 reasons. First there price was not the best and yes they did do a match after a email after ordering. I tried doing it over the phone but that was not a option. Secondly they shipped me the wrong part I ordered a right and left and got 2 lefts. Then had to wait for me to return there mistake before they shiopped me another. I use the rack for buisness and this has inconvienced me.

by: Dana 08/16/2018

I received my part for my rack. It took longer than I anticipated but your company did update me that the part was delayed due to manufacturers delay. I did appreciate the update and due diligence to get the part to me. Cudos on get the order right and getting it to me.

Recommended Tonneau Cover For a 2024 GMC Sierra 2500 Compatible With Thule TracRac Ladder Rack

Is TracRac Sliding Ladder Rack Compatible with Additional Lower Sliding Roof Rack
Thule has not yet made a roof rack style connection to work with their sliding base rails but you are not the first person to ask. Basically you can make something work, but there is not a warrantied application available or a confirmed weight rating, so it would be a one-off custom. What you can do if you want to proceed is you can use the Replacement Modular Slider for TracRac G-2 Truck Bed Ladder Left Front/Right Rear # TA01-42003 and Right Front/Left Rear # TA01-42004 which are the...

Tonneau Cover Compatible TracRac System For A 2019 Chevy Silverado 1500
Hey Mike, I can definitely help with this. You are correct that to make your TracRac tonneau cover compatible, all you would need to do is add the base rails and swap out the feet (modular sliders as Thule calls them). That said, the cost of these individual components can add up, and buying a whole new system does seem like the logical thing to do. You would need two of part # TA01-42004, two of part # TA01-42003, the base rail set # TH21781 and four of the knobs # TAKB-90030-1. With...
