Goopy 1/2" Studs ...Available for all 12A, 13B & 20B 3rotor.
Goopy Performance's Oversized main Engine studs provide a better alternative to the usual dowel pinning method of strengthening the engine.
Goopy Performance Oversized Main Engine Bolts require drilling on rear & middle irons along with both rotor housings to accommodate their larger diameter.
Goopy Engine Studs are sold with a stock (oem) thread pitch that Do -NOT require the drilling or tapping of the front iron.
(We do have a stud with a 1/2-20 thread pitch that does require tapping of the front iron upon special request.)
Goopy Performance Oversized studs are sold in sets of five, along with five seal/washers & a 12point flange nut.
Special pricing to forum member when you buy any of our other parts.
