Short dust seal used by SOME Core shifter bases since 2023 with straight machined stub. Your old seal must look identical to this one.

• Not interchangeable with older models, specific hardware is required
• NOT ALL bases use this! Check before you buy!
• Does NOT FIT any other brand

• Upper straight section seen in image is CUT OFF
• This part is also used as a lower seal in different models with straight section intact - see separate listing
