Ultima®’s performance carburetors are directly interchangeable with S&S® Super G and Super E Carburetors. Ultima® carburetors will accept S&S® jets and S&S® bolt pattern air filter assemblies & manifolds.

Patented design improvements - a relocated accelerator pump nozzle for increased throttle response and THUNDER JETS are a bolt on!

Simply remove the plugs and screw in the Thunder Jet. No expensive machining required! Installation & tuning instructions
