Adapter to Connect JetStream Bars to BaseLine Towers
Updated 12/22/2025 | Published 10/18/2024
Question:
I have baseline towers and i am upgrading to jetstream bars from core bars. I have 8880637 adapters in the cart but im reading here in the description that these HD adapters will also work? The jetstream adapters 8880637 also say they will work for HD bars. but In your Q A it is stated that these will not work for Jetstream bars? These HD bar adapters are 10 bucks cheaper for 4. Will they work for jetstream bars to baseline towers? Thanks

Hi Brett; they look the same but according to Yakima the # 8880637 is what you need for your JetStream bars. The other adapters are just for the HD bars. Yakima is usually pretty good about letting us know if things work even when they aren't designated to so I'll trust them on this one.
