  • Recommended Extended Ball Mount or Hitch Extender for Towing Boat Trailer
    For your 2018 Tahoe and boat trailer needing a longer extension between them I recommend the Brophy Ball Mount for 2" Hitch - 3/4" Rise, 2" Drop - 13-1/4" Long - 10,000 lbs # BM20. Having a longer ball mount like this will not reduce the capacity of your hitch at all. This will give you a length of 13-1/4 inches from the center of the ball to the hitch pin hole. For a compatible hitch ball the shank needs to be 1 inch diameter for this mount. I recommend the 2 inch ball # 40038 or...

  • Hitch Extender for Clearing Spare With Bike Rack on 2024 Land Rover Defender
    Hey Azmi! You can use a hitch extender to clear that spare on your Land Rover Defender. However, you have to keep in mind it will reduce the capacity of your hitch by 50%. As long as your bikes and bike rack don't exceed half the tongue weight capacity of your hitch you're set. It doesn't have to be anything fancy so I recommend the RockyMounts Hitch Extender # RKY10008. This is an 8" extension that also includes a locking hitch pin to keep it secure. I also recommend adding the etrailer...

  • Hitch Extension to Use with Bike Rack for Subaru Outback Wagon
    Hey Jim, it sounds like you are looking for a hitch extender because of the shorter shank that is on your quikerstuff bike rack. For that the RockyMounts # RKY10008 would work great for you. This would give you 8 more inches of clearance which I would think would pretty easily be enough. Plus this comes with an anti-rattle device which would minimize movement in the hitch as well. Would 8 inches be enough?

  • What 4-Bike Tilting Rack do You Recommend to Open My Trunk with Bikes Loaded?
    I have a great solution for you. However, the Thule Hitching Post Pro # TH934XTR can only tilt when bikes are unloaded. If you are set on a 4-bike rack that can tilt with bikes loaded to access the rear hatch on your 2016 Lexus RX 350, the best option is the Saris Freedom Bike Rack for 4 Bikes - 2" Hitches - Frame Mount # SA4414B or the fat-bike version # SA4414B-FB for bike tires that measure between 3-5 inches wide. While we cannot confirm for sure whether you can open the rear hatch...

  • Hitch Extension Options
    We have the Yakima StraightShot Hitch Extension, # Y69VR and the RockyMounts Hitch Extender, # RKY10008, among others. The problem however is that most manufacturers state these type products are not to be used with accessories on RV hitches. The amount of sway the back of many RV's receive can cause a lot of torque to be placed on the hitch. There are other similar items such as these two but be aware of the recommendation to not use on an RV. Your best bet is to consider shifting how...

  • Trailer Hitch Adapter to use Thule DoubleTrack Bike Rack
    I have a solution for you that will allow you to continue to use your Thule DoubleTrack Pro XT Bike Platform Rack # TH92BJ, which does require you have a hitch pin hole at least 1-1/2" from the face of the receiver. The most cost-effective option is to use the Rockymounts Hitch Extender # RKY10008 which is designed for use with a bike rack so it has the necessary length from the hitch pin hole to the receiver. This extender will work in a 2" trailer hitch, which is the size you should...

  • Does Hollywood Racks Destination Bike Rack Fit 2023 Jeep Wrangler 4xe
    Yes, assuming your 2023 Jeep Wrangler 4xe has a trailer hitch it is compatible with and can carry the Hollywood Racks Destination Bike Rack # HLY94FR. You just need to ensure you have the right clearance for the spare tire, and that will depend on your hitch. For example, when we test fit the Curt Trailer Hitch Receiver # C13392 on a '23 Wrangler 4xe we found it measured 9 inches from the hitch pin hole to the edge of the spare tire. The Destination measures 9-1/4 inches to the closest...

  • Comparing the RockyMounts Hitch Extenders RKY10011 and RKY10008
    There are a few differences between the RockyMounts Hitch Extender part # RKY10011 (LS) and part # RKY10008. The first is that the LS model has a premium lock core body which more durable. It also has a better anti-rattle design so there will be a further reduction in movement.

  • Can I Use The Thule T2 Pro XT On A 2007 Toyota FJ Cruiser
    Yes, the Thule T2 Pro XT can work on your 2007 Toyota FJ Cruiser. Unfortunately, you will have to get an additional item for it to work. You will need to add a hitch extender to use this hitch bike rack. I recommend the RockyMounts Hitch Extender w/ Hitch Pin and Lock - 2" Hitches - 8" Long, part # RKY10008. It will adds 8" of length of your trailer hitch receiver. But keep in mind, whenever you add a hitch extender, you reduce the maximum tongue weight and the maximum gross trailer weight...

  • How to Determine if Yakima FullSwing Will Clear Spare Tire on 2020 Jeep Wrangler Unlimited Sahara
    For your application I recommend using the Draw-Tite Class III Trailer Hitch # DT78MR because when we installed it on a 2020 Jeep Wrangler Unlimited we found that from the center of the hitch pin hole to the rear edge of the bumper was 1". The Yakima FullSwing # Y02465 has a max distance of 6-3/4" from the center of the hitch pin hole to the furthest edge of the tire. Since the Sahara has a different bumper than the normal Wrangler you'll likely need the RockyMounts Extender # RKY10008...

  • Can the Thule T2 Pro XTR Bike Rack Be Used with a Hitch Extender on a Sprinter Motorhome
    It really depends on the capacity of your hitch. Using an extender like the RockyMounts Hitch Extender # RKY10008 will decrease your hitches capacity by 50%. So, realistically you will need a hitch that has a tongue weight capacity of 400 lbs. or higher because that will then be cut in half. If your hitch is rated high enough, then you can use the Thule T2 Pro XTR Bike Rack # TH83JV. If your hitch is not rated high enough, please let me know. Also, provide me with the measurement from...

  • Will RockyMounts Hitch Extender RKY10008 Work With RockyMounts BackStage Bike Rack?
    The RockyMounts Hitch Extender w/ Hitch Pin and Lock - 2" Hitches - 8" Long # RKY10008 you were looking at is the correct extender for the RockyMounts BackStage Bike Rack for 2 Bikes - 2" Hitches - Wheel Mount # RKY10002 you mentioned. This 8" extension will give you the additional clearance you need to clear the spare tire on your 2020 Jeep Wrangler. With that said there is not a way to order the # RKY10008 with a lock that matches the key your bike rack uses. I included videos of...

  • Hitch Extender Recommendation to Clear Jeep Spare Tire
    Thule usually says to avoid using an extender with their bike racks but if you choose to do so to fit the Thule Apex Swing XT # TH9027XT with your spare tire then I recommend using one that has an anti-rattle device to keep everything secured really well. It's also worth noting that typically when you add an extender the catch is that you're reducing the weight rating of your hitch by 50%. I recommend checking out the RockyMounts Hitch Extender w/ Hitch Pin and Lock # RKY10008 because...

  • Depth of Pin Hole to End of Internal Shank for Hitch Extender # RKY10008
    From the center of the hitch pin on the female 2 inch hitch portion of the # RKY10008 to the back of the hitch opening measures right at 3-1/2 inches so since you need at least 2-7/8 inches this would fit and work well for you.

  • Hitch Extender For Use With Swagman E-Spec Bike Rack
    Hey Deb, There is not a bike rack rated for use with travel trailers that has the length you need, so you will need the extender you mentioned. It does halve the rating of your hitch, and since it's rated for 300 lbs tongue weight, that will mean it's capacity will be lowered to 150 lbs. That's okay though because the total weight of the rack and your bikes will be less than that. So here's what you can use: - Swagman E-Spec Bike Rack # S94FR - RockyMounts Hitch Extender w/ Hitch Pin...
