Clutch linkage
 

Any modifications allowed to the linkage? Stiffening, bracing, etc? Must use factory style throw out bearing,not hydraulic? Stock Eliminator

Hydraulic not allowed. Although maybe ok if it came that way. You don’t want hydraulic anyway. You can make any mechanical linkage as long as it is foot release with a pedal. With the clutches we run today, it doesn’t have be allbeefed up like the old days.

Like James has stated, hydraulic clutch release is not the best choice for a racing vehicle. This is due to the fact that the hydraulic system is somewhat slower than a mechanical clutch linkage is. The linkage may be strengthened and braced but must retain the original clutch linkage design. (NHRA Stock and Super Stock classes)
NHRA Super Stock Modified class vehicles may use clutch and brake pedals mounted to the floor.
