SEVERE-DUTY SERIES
THROTTLE SHAFTS    
     Standard in Severe-Duty™ throttle-body assemblies, these triple ribbon shafts are also offered separately. Choose Stage-I or profiled or Stage-II versions. Our stamped, 430-stainless levers are TIG-welded to precision-machined, deburred shafts. Unnecessary stock-type provisions (e.g., transmission-kickdown holes) and protrusions that can hang on the air cleaner or collect track debris are eliminated. The linkage-actuation end features three 1/4" extrusions, designed to accept the 1/4" ball end of race-car throttle linkage. All springs are stainless steel, including stronger-than-stock throttle return springs. A provision for dual return springs is built in. The final treatment is a thermal-set, dry-film lubrication.
