Ultima is now offering our Twin Cam 99-06 “A” engines in 100 or 113 C.I. Just like our 100” Evo engine this is a great replacement for worn out stock engines. These are built using a milder camshaft and lower compression than our 113” twin cam. These engines offer easier starting, extremely smooth cruising but still make great power. They come in black, silver, blackout and polished finishes.
