Question:
Hello According to your website the dermal disk brakes for my RV are DE68YR. My RV came with hybrid drums that are the ones with threaded dust cap. HUB ASSY-BRAKE HUB-865H-9/16-HYBRID-GREASE-CURT 8537391 GRS CAP - 8K - BLK - SMOKE - W/ORING -WO/CTR PLUG Deemaxx sales a kit with threads but I do not see it at Etrailer as an option. When you will be selling those?

Hi Javier,
We do offer the DeeMaxx Threaded Dust Cap AT-6-8K-LC under part # DE38AR. This has a 2-7/8" thread diameter, matching Curt's hybrid grease cap diameter. Were you going through our fitguide with your trailer's info or just searching part numbers? Are there any other components you need?

I think you misunderstood my question. DE68YR from Deemaxx does not allow threaded caps. Deemaxx sells another one that accepts threaded caps but E-trailers do not sell them yet. My OEM Drums comes with this one https://www.lippert.com/lippert-trailer-axle-oil-and-dust-cap-with-set-screw-oil-dust-cap-set-screw?queryID=bd195ada700270da2dd72ac70a8500f6&objectID=22554&indexName=gwp_d2c_prod_lippert_products I would like to use the same ones.
