Question:

Thank you for all your help with our Grand Design 2400BH. I ordered the parts that you recommended from E-trailer yesterday, and had them sent to our trailer in Washington. I was so impressed with your help I want to do the same modifications to our new TT we have up here in Alaska. We have a 2023 Grand Design Momentum 23G. We would like to get the equalizer, wet bolts, and the Sumo Springs. Could you get me the part numbers again for this camper? I forgot to add bearing kits to my order yesterday. Could you please get me part numbers on bearing kits for both Travel Trailers also? Thanks again for your help you have been fantastic.

Since the parts are different for your 2023 Grand Design Momentum 23G we will go a slightly different route. You currently have a standard # TREQ104 equalizer on the trailer. That means the best fit is going to be the Dexter E-Z Flex Suspension Kit # K71-652-00. This includes the upgraded shackles, wet bolts, and bushing so there is no need to purchase them separately. I have this kit on my Jayco which you can see in the installation video below.

For the SumoSprings you will need the # SS26MV. Once again, these have the overslung design but with a higher capacity since you have 6k axles. These also come in pairs so you will need a quantity of two to add them to each axle.

The bearing kit for the 2023 is either the # BK3-100 or # BK3-110. The main difference here is the inner diameter of the grease seal. Both kits come with # 15123 outer and # 25580 inner bearings. The 100 has a # 10-36 grease seal with an ID of 2.25" and the 110 has a # GS-2125DL seal with an ID of 2.125". If you can send me the information from your axle tag I can find out which it uses. I wasn't able to get the information from Grand Design. For the 2021 Imagine 2400BH you need the # BK2-100.
