This bolt-on BBD carburetor replacement fits directly onto compatible Jeep CJ models with 258ci engines, ensuring a straightforward and clean setup without the need for drilling.

      Application. Specifically designed for 1979-1986 4.2L Jeep CJ7 models, this EFI system ensures precise fitment and optimized performance without the need for modification.
