Video Transcript for Review of Yakima FatCat and FatCat EVO T-Slot Kit - Y03098
Hi there, I'm Michael with etrailer.com. Today, we're gonna take a quick look at this Yakima Aero Crossbar Smart T-Slot Kit. This conversion kit is going to allow you to mount your FatCat or FatCat EVO to a T-slot crossbar. This is going to allow for a quick and easy installation. It's also going to have a nice low profile look for you. So rather than having the clamps that wrap around your crossbars, and these will allow you to just slide right in to those T-slots on those crossbars.
Now, this is going to work with the Yakima JetStream, FlushBar, RailBar, and most other T-slot style crossbars. They do include instructions to help you get everything set up properly so you can ensure that your ski and snowboard carrier, as well as your skis and snowboards, are going to have a nice, snug fit onto those crossbars. So you are going to get four of these spacers, as well as four bolts. And this does come with a limited lifetime warranty, so you can trust it is going to hold up well. And because it is coming from Yakima, you can trust it is gonna integrate well with the FatCat and FatCat EVO system.
So, and that completes our look for today. Again, on Michael with etrailer.com. Thanks for watching.

This SmarT-Slot kit is perfect for my ski carrier and Yakima rack. What is equally exceptional is etrailer's service. Although this kit was out of stock, I was able to order it and they gave me constant communications on the status of my order. They're a great company to deal with on both big and small items like this one. Can't say enough.

Used these to remount a Yakima ski/board rack on our Audi Q5. A lot easier to use than the stock mounts the rack came with. More importantly it lowered the rack making it much easier to load and unload our skis.

It's such a simple product, but makes such a huge difference in terms of speed of installing/uninstalling the racks, aerodynamics, and style! Still plenty of clearance for my bindings between the rack and tonneau.

Looks great, Simon! Its nice that you get the clearance you need without having to roll up your tonneau.

The T-Slot kit definitely gives a better-looking, lower profile than the aero bar straps that come with the FatCat. Super easy to put on and remove. Gives your more placement options, where the towers limit your positioning with the aero bar straps.

These worked great to retrofit my older (2008?) FatCat Evo6 carriers and be able to mount them on stock 2024 Mercedes cross bars. Very easy installation.

With the durability of the Yakima accessories the ability to take advantage of the t-slot system and retro fit my big ski racks that had the wrap around clamps makes swapping on and off ski racks a breeze. Like everything outdoor related during the pandemic these were on back order everywhere. Yakima told me to order from etrailer because they restock their resellers before their own parts warehouse. Customer service and communication on order status was prompt and often. The ability to now slide on the ski racks through the t-slots on the ends instead of the multi step oval screw down clamps that came with my fat cat 6 takes all the hassle out of putting racks on for a day in the mountains, getting home and sliding them off in 2 minutes so I’m not keeping them on all season.

Good product cleans up the overall look of the carrier. I does deform the rubber wind slot on your rack so when removed you here a whistle for several days until rubbers heats back up with sun and it falls back into place.

- Does Yakima SmarT-Slot Mounting Kit Fit T-Slots on LockNLoad & JetStream CrossbarsHello Luke, Yes, the SmarT-Slot Kit 2 for Yakima FatCat Ski and Snowboard Carriers # Y03098 and Yakima SmarT-Slot Mounting Kit for Yakima SkyBox NX, GrandTour, and CBX Cargo Boxes # Y25AV fit the JetStream crossbars as well as the LockNLoad.
view full answer... - Can A T-Slot Adapter Be Used With The Yakima Powderhound 4The Aero Crossbar SmarT-Slot Kit 2 for Yakima FatCat Ski and Snowboard Carriers # Y03098 is not compatible with your Yakima Powderhound 4. This has been confirmed by Yakima that there is no adapter for the Powderhound 4, and the only mounting hardware available is the Replacement Mounting Hardware for Yakima PowderHound, Big PowderHound or FreshSesh # Y8860040 which attaches to the carrier, and wraps around the crossbars.
view full answer... - What Is The Difference Between T-Slot Mounting Hardware 8860085 And Y03098Yes, the Replacement T-Slot Mounting Hardware for Yakima FatCat and Whispbar Ski Carriers # 8860085 you mention will work with your Yakima Fat Cat 6 Locking Rooftop Ski and Snowboard Carrier # Y03088 (INACTIVE). The difference between # 8860085 and # Y03098 is the primary height at which they sit. The Yakima FatCat 6 will still operate normally, and will all you to channel mount your FatCat 6 into your aero style crossbars like the Yakima JetStream Crossbars # Y00425. For a low profile...

The necessary hardware can be found in the Aero Crossbar SmarT-Slot Kit 2 for Yakima FatCat Ski and Snowboard Carriers # Y03098. I spoke with my contact at Yakima and confirmed this hardware is what you will need to mount the FatCat to your crossbar's...
view full answer... - Is There a Mounting Kit to Attach Yakima ButtonDown 6 Ski Carrier On Yakima Crossbars With T-Slot? With your Yakima ButtonDown 6 being obsolete you are going to have to replace it with a new carrier like the Yakima FatCat EVO 6 # Y03096. This includes mounts to wrap around your crossbars or we do have the T-Slot Kit # Y03098 which will allow you to use the t-slots in your rails.
view full answer... - Can I use Yakima SmarT-Slot Kit in Thule Xsporter CrossbarYes, you can use the the SmarT-Slot Kit 2 part # Y03098 to mount your FatCat EVO part # Y03096 to the T-slots in the Thule Xsporter crossbars. I went to the warehouse and tested the Yakima bolt in the T-slots of a Thule Xsporter bar and it fit perfectly. You can use the Yakima SmarT-kit 2 in any Thule Xsporter bar T-slot. The FatCat EVO part # Y03095 fits crossbars up to 3-7/16 inches wide by 1-1/2 inches tall. The Crossbars of the Thule Xsporter ladder rack are 3-1/3" inches wide by...
view full answer... - Differences Between the SmarT-Slot and Replacement FatCat Mounting Kit for Yakima Ski RacksBetween these two parts, the SmarT-Slot, part # Y03098 and the Replacement Mount kit, part # 8860085, the primary difference is the height at which they sit. The FatCat 6 will operate normally. Both of these kits will allow you to channel mount the FatCat 6 on your aero style crossbars. The Replacement Mount kit, part # 8860085 is likely the better choice if you have higher bindings as it sits taller than the SmarT-Slot kit, allowing you to clear the roof with the taller bindings.
view full answer... - Is the Yakima Aero Crossbar SmarT-Slot Kit 2 Compatible w/ Yakima HD Crossbars and the FatCat EVO 4Yes, the Aero Crossbar SmarT-Slot Kit 2 for Yakima FatCat Ski and Snowboard Carriers # Y03098 will work with Yakima HD Crossbars Aero Crossbars # Y01157 and the Yakima FatCat EVO4 # Y03095. The SmarT-slot kit is designed to mount your FatCat EVO 4 to T-slotted crossbars, the Yakima HD Crossbars are T-slotted crossbars so this is exactly what you need.
view full answer... - What Upgrades Were Made to the Yakima Fat Cat EVO over Previous GenerationThere are a few noteworthy improvements for the FatCat6 EVO, part # Y03096 over the previous version of the FatCat 6. First being Yakima's newer rubber coated steel strap mounting system. This is an extremely quick to mount system that locks using the integrated Same Key System. It fits AeroBars sized up to 3.5 inches wide by 1.75 inches tall, and didn't fit those in the previous version. The EVO also includes additional adapters for round and square bars, letting it attach to a wide...

I don't suggest making holes in the roof rails. We cannot provide the information to install them in that manner. I recommend using the HD Bar SL Adapter for Yakima BaseLine, SkyLine, TimberLine, and RidgeLine Towers - Qty 4 Item # Y03541 the Landing Pad 15 for Yakima Control Towers - Qty 4 Item # Y00241 and the SkyLine Towers for Yakima Crossbars - Fixed Mounting Points, Flush Rails, and Track...

The Thule Aero Blade crossbars like # TH7603B-TH7603B with fit your 2017 BMW X5 but you will also need the discontinued fit kit 4023 for that specific fit. You may want to consider a different option if you don't already have that roof rack. I've linked the page to...
view full answer... - How to Tell if Yakima FatCat EVO Fit T-Slots of Tesla Model YHey Leland; thanks for the question and let's start with the accessory you were mentioning, which is the Crossbar SmarT-Slot Kit 2 for Yakima FatCat Ski and Snowboard Carriers # Y03098. This is what is needed to add the T-bolts to both the Yakima FatCat EVO 4 # Y03095 and EVO 6 # Y03096. That said, I don't know the exact T-slot dimensions of the Tesla Model Y's crossbars. You'll have to measure the T-slots, and I can tell you the T-bolts of the Yakima kit are 1/4" by 1/4". So you can use...
view full answer... - Will Yakima Aero Crossbar SmarT-Slot Kit Bolts # Y03098 Fit Thule M6 Wing Nut I actually went out to our warehouse to test a bolt from the Yakima Aero Crossbar SmarT-Slot Kit # Y03098 with an M6 wing nut from Thule (part # 753-0783). The Yakima bolt threaded into the nut perfectly which means it is indeed an M6 bolt. They will work just fine with a Thule M6 wing nut like what you have.
view full answer... - Aero Crossbar SmarT-Slot Kit 2 for Yakima FatCat 4Yes, you can use the SmarT-Slot Kit 2 # Y03098 to attach your Yakima FatCat 4 like part # Y03095 to your flush mounted AeroBlade crossbar roof rack. It's a very useful kit to have since the FatCat4 version is known for having short straps that don't fit around certain bars. A tip while using this kit though it to make sure you evenly tighten down on the T-slot on each side of the crossbar.
view full answer... - Distance Between Mounting Location on Yakima Fatcat 4 and Fatcat 4 EVOThe Yakima FatCat EVO 4 Ski and Snowboard Carrier - Locking - 4 Skis or 2 Boards - Black # Y03095 has mounting holes that are inches apart. I reached out to my tech contact at Yakima and he said the Old FatCat 4 mounting holes are 12 inches on center and the newer FatCat 4 EVO will be longer at about 16 inches. Once you account for the width of the Aero Crossbar SmarT-Slot Kit 2 for Yakima FatCat Ski and Snowboard Carriers # Y03098 it will be another 1/2 inch on each side for the T-slot...

- Ski Rack for 2020 BMW X3 With Factory Roof RackWe do have an option for you but I checked with both Thule and Yakima and neither of their ski racks will clamp directly around the wider 4 inch crossbars of your 2020 BMW X3's factory roof rack. However, based on my research it looks like your BMW's rack does have a T-slot (channel) at the top of the bars. What I recommend is the Yakima FatCat EVO 6 Ski and Snowboard Carrier - Locking - 6 Skis or 4 Boards # Y03096 with the Aero Crossbar SmarT-Slot Kit 2 for Yakima FatCat Ski and Snowboard...
view full answer... - How Much Height Will I Lose with the Aero Crossbar SmarT-Slot Kit 2The distance from the top of the crossbar to the top of the carrier while using the mounts that are included with the Yakima FatCat EVO like part # Y03095 is 4-5/8". This same distance while using the Aero Crossbar SmarT-Slot Kit 2 part # Y03098 is 3-1/2" therefore it will become about 1-1/8" shorter.
view full answer... - Using the Yakima FatCat Evo 6 with Rhino-Rack RSP and the Yakima SmarT KitThe FatCat EVO 6, part # Y03096 can use Yakima's SmarT Kit, part # Y03098 to fit to your Rhino Rack RVP's, part # RRRVP27 T-Channel slot. I recommend tightening the T-Screws as tight as possible to make sure that the carrier seats onto the bars.

If you are concerned about the angle of install, you can use the the Roller Accessory for Rhino-Rack Pioneer Platform Racks - 50" Long # RR43131 to roll your snowboards into place.

If you are concerned about fit, I recommend you look at the Yakima FatCat EVO 6 Locking Rooftop Ski and Snowboard Carrier - 6 Skis or 4 Boards - Mirror Black # Y03096 as an alternative. It has the integrated SkiLift to provide clearance for tall bindings. It is also able to be used with T-slots if you add the Aero Crossbar SmarT-Slot Kit...
view full answer... - Best Yakima Roof Rack For 2020 Jeep Grand Cherokee With Black and Chrome TrackI recommend the Yakima JetStream Crossbars # Y00425 with the SkyLine Towers part # Y53TR and landing pads for the towers part # Y00244. The JetStream and CoreBar are very similar with a 165 lb capacity and aerodynamic design to cut down on wind noise. However, The JetStream bars offer the T-slot for accessories with a rubber weather strip that does not require trimming like it did in the past. I highly recommend using the JetStream bars with the T-Slot and getting the Yakima FatCat Ski...

Most ski carriers come with just the wraparound installation kit but you can upgrade the mounting hardware to fit into T-Slots with an adapter kit like what I mentioned above.

The SmarT-Slot for Yakima ski carriers has been a great investment for easy on and off of the carriers. I would highly recommend getting it.
