SHARKPUP ADD-ON
1.0" Plunger Tube
Description
The Sharkpup Add-On is a compact expansion for the Hammerhead platform that enables use of the common 1.0" ID plunger tube. It reduces overall profile and lowers friction during cycling, trading peak power for smoother handling and a lighter form factor. The add-on includes Pup variants for Hammerhead, Mokarran, Scoophead, Bonnethead, and Thresher.
