Harley Big Bore Kits
Deadbeat Customs knows Big Bore Kits are the key to increasing displacement on your Harley. Big Bore Kits replace your stock pistons and cylinders with larger ones, leading to greater displacement. When it comes to performance there’s no replacement for displacement! We have an excellent selection of kits manufactured by S&S Cycle, which come complete with all instructions to ease the installation process. The Big Bore Kits come complete with all necessary hardware. The only decisions you’ll need to make will be choosing the right fitment and finish.
