Video Transcript for Thule Hitch Bike Racks 852-3037-001 Review

Speaker 1: Today we're taking a look at the replacement anti sway attachment for Thule Apex and Helium Aero bike racks. This unit replaces one ant sway attachment on the holdfast cradle of your Thule Apex or Helium Aero bike rack. It fits Thule Apex models TH9025, TH9026, and TH9027 and it fits Thule Helium models TH9042, and Th9043. Now this is designed to work with the cradle and a rubber strap to prevent your bike from rocking back and forth during transport. It attaches to the angled extension on the bottom of the cradle or directly to the cradle if you don't have the angled extension. It protects your bike frame from scratches because it features these really nice, soft thermoplastic elastomer bumpers.

So it's a really nice designed unit. It really cushions it so that way it's not the construction of the bike on bare plastic, but makes contact with these bumpers to protect the bike finishing and the bike frame from scratches abrasions or any type of damage. That's gonna do it for today's look at the replacement ant sway attachment for the Thule Apex and Helium Aero bike racks.

Prevent your bike from rocking back and forth during transport by replacing a lost or damaged anti-sway attachment for the Hold Fast cradles of your Thule Apex bike rack. This part attaches to the angled extension on the bottom of the cradle.


Thanks for keeping me up to date with my order. This was a hard-to-get item for me as I recently lost one off my Thule Helium rack (which was also purchased at along with the hitch!). Service from has always been excellent and I wouldn't look any place other than for hitches or racks.


These fit my bike rake as advertised. Prompt shipping and follow up from a company rep to ensure satisfaction.


On-time delivery. The emails during the delivery process and the follow-up once the order was delivered made the experience feel very personalized. I will use etrailer again for my upcoming purchases.


Easy to use. Works well to stabilize any bike we've used on the rack. Due to design of rack remember to remove bar if rack is on the car without a bike. We lost a bar that way.


I have lost many off these anti sway attachments. They easily dislodge from the bike rack.


I own the Yakama swing Daddy bike rack and the Thule Apex 4 bike rack. I think this part should've been part of the Apex bike rack in the first place. In general I think Yakama makes a better bike rack with a permanent anti-sway mechanism so it can't get stolen. The Thule anti-sway attachment can easily be stolen, so I would recommend taking it off when you leave on your bike ride. This part does what it should, but keep in mind you may need the angled extension part as well since the Apex bar is curved. Putting the anti-sway attachment by itself may not allow the bike to hang straight down. eTrailor did a great job shipping my item and keeping me updated on the status of my shipment.


This is an exact replacement of the anti-sway for a Thule Helium rack purchased about 4 years ago, before a design change of the Helium. My local retailer (where I bought the rack) said the part is no longer available. It's been difficult to track down "old design" with rubber straps versus "new design" with plastic straps, but the photos on eTrailer helped me find the correct part. Thank you!


Over the last few years, I've needed several random parts for bike racks. These guys have always had the part, priced it fairly, delivered on time....and didn't stick it to me on shipping. Well done.


Great service from etrailer! The Thule anti-sway attachment works very well to stabilize the bike while it hangs from the rack.


Exact replacement for lost part of older bike rack


As described, will stop my bikes from swaying now while driving


Worked perfectly. Replaced the ones I lost along the road somewhere. ETRAILER’s stock and service are excellent.


So far. The replacements seem to be working as intended. Thank god for to provide replacement parts for my 5+ year old bike carrier at a reasonable price.

My original anti-sway attachments were stolen from my rack. Ah, people - some of them good, some of them bad. If you are not using the rack, I would suggest removing the anti-sway attachments - they are too easy to steal.


This was the exact part I needed for my bicycle rack.

Still works great.

After my son borrowed my bike rack three of the four clips were missing. On a whim I looked for them online and discovered stocked them. I ordered three and they arrived in no time. I appreciate the fast service and what I feel was a good price for the item.

The items are working great. No issues.
Marc - 07/26/2021


The part was just what we needed and we couldn't find it anywhere else. The price was spot on and shipping charge was reasonable. The response to the order was immediate and delivery time was good. I am a satisfied customer and recommend Thanks!


Genuine Thule part, just what I needed.


Arrived earlier than expected, fit perfectly. I actually installed this on the Thule 934PRO Hitching Post Pro.


Fit perfectly!


The parts fit our TH9043 bike rack perfectly!! I forgot to order straps but I took the ones off the middle of the 3 bike holders (we only carry two bikes at a time) & used them instead of ordering straps. We're back whole & ready to ride! Thank you for a GREAT product & holding my order (& prices) until they came in!


The price was amazing! I purchased 8 of these Anti-sway attachments for my Thule bike rack. Thule was charging almost $30.00 for two! Not only was the price wonderful but the customer service-outstanding. I had my order in a few days!! Love this company! Thank you!

Cheryl R - 09/19/2016


This part matches EXACTLY what I needed.


This was the perfect replacement to the piece I had lost at the end of last season. Throughout the ordering - receiving process, I always felt as if etrailer kept me informed about the progress of my order & when to expect arrival. It came today and has been installed on my bike rack already.


Poorly designed, they keep falling off.


see product review for the other part that connects to this. It is poor from the viewpoint that they should be one so they are not lost and have a permanent attachment to the Thule bike rack.

I keep losing them. This is a poor design by the manufacturer. However, your service has been absolutely great.

  • Will Anti-Sway Attachment 852-3037-001 Fit a Thule Vertex Bike Carrier
    The Thule Vertex bike carriers use a version of the Hold Fast cradle so the anti-sway attachment # 852-3037-001 will fit the cradles on your Vertex too!

  • Will The Thule Replacement Anti-Sway Attachment # 852-3037-001 Work on a Rola Bike Rack?
    The Replacement Anti-Sway Attachment # 852-3037-001 that you are asking about is meant for Thule Apex and Thule Helium Aero Bike Racks only. I do not recommend interchanging bike rack parts; especially between different brands. The replacement Anti-Sway Device and Strap 59407 (DISCONTINUED) worked for the Rola TX-102, TX-103, and TX-104 Bike Carriers. This is unfortunately no longer available.

  • Replacement Anti-Sway Attachment, Strap, and Cradle Overmold for Thule Helium Aero 2 Bike Rack
    I checked with Thule for you and we do have the replacement parts for your Thule Helium Aero bike rack, though keep in mind the whole cradle is not available, just the cradle overmold (the top part); what you need is the following: - Replacement Anti-Sway Attachment # 852-3037-001 - Replacement Strap for Cradles on Thule Bike Racks # 852-3006-001 - Replacement Cradle Overmold # 852-3003-001 I have added links below to some video reviews for you to check out as well if you'd like.

  • Replacement Anti-Sway For Thule 9042 Helium Aero 2
    The anti-sway portion of the cradle on your Thule Helium Aero 9042 bike rack consists of three pieces. The extension clip that attaches to the underside of the actual cradle that the bike frame tube sits on which is part # 852-3108-001, the anti-sway cradle itself that joins the clip and the strap, which is part # 852-3037-001 and the strap which is part # 852-3006-001. Just look at the product photos on the pages I've linked, and choose the parts you need.

  • Replacement Anti-Sway Cage for a Thule Raceway TH9002PRO Trunk Mount Bike Rack
    The new version of the RaceWay, # TH9002PRO, or the older 9002XT, uses anti-sway attachment # 852-3037-001. If you have the previous generation of the Raceway, 9002, (the anti-sway part would not have any blue parts on it) then you would need # 853-7758. For either version you can use strap # 852-3006-001.

  • Replacement Strap, Anti-Sway Attachment & Lock for Thule Archway XT 9010XT
    I can definitely confirm the correct replacement straps, anti-sway attachment and lock/key for your Thule Archway XT 3-Bike Rack 9010XT; you had the strap right, but do need a different anti-sway attachment. I verified these are the correct parts for you with the manufacturer: - Replacement Strap # 852-3006-001 - Replacement Anti-Sway Attachment # 852-3037-001 - Thule One-Key System Lock Cylinders # TH450200 I have added links to video reviews for you to check out as well.

  • What Is The Difference Between Thule Cradle TH8523486001 And Thule Cradle 852-3037-001?
    The two parts you are looking at differ slightly in design/size and are actually for different bike racks. For example, the Replacement Anti-Sway Cradle # TH8523486001 is for Thule Raceway TH9001XT and TH9002XT while the Replacement Anti-Sway Attachment # 852-3037-001 is for Thule Apex TH9025, TH9026, TH9027, Thule Helium TH9042, and TH9043. If you can tell me which bike rack you have then I would be more than happy to track down the correct part.

  • How Important are the Anti-Sway Cradles?
    The anti-sway attachment # 852-3037-001 is a very important part of any hanging-style rack. Did you get your Thule Helium Aero 3 second-hand without the anti-sway attachments? The Thule Helium Aero 3 TH9043 was discontinued and replaced by the Thule Helium Pro 3 #TH9043PRO, but you can see in the attached picture how they all came with the anti-sway parts. They are there to GREATLY reduce the sway of the bikes on the road and minimize the bike-to-bike contact. Without them, your recommended...

  • Replacement Cradles for Thule Apex XT 2 Bike Rack for Different Style Cradle Than New Hideaway
    The Thule Apex XT 2 Bike Rack for 1-1/4" and 2" Hitches - Tilting # TH9024XT has the hideaway cradles that are the update from the Hold Fast cradle # 852-3005-002 you referenced. I measured the Apex and the cradle and they will fit but they don't screw in place like the new cradles. Then you will use the Replacement Anti-Sway Attachment for Thule Archway, Gateway, Roadway, and Vertex Bike Racks - Qty 1 # 852-2903-001 and straps # 852-3006-001.

  • Replacement Anti-Sway Attachment for Thule Stay-Put Bike Rack Cradles
    Cradle # 853-7887 is called the Stay-Put cradle. But Anti-Sway Attachment # 852-3037-001 was designed for the Hold Fast cradles. What you would need instead is # 853-7758 for a proper fit. I have linked a video review of it for you.
