Transmission Studs

6 products

Transmission Studs for Harley-Davidson are the threaded fasteners that locate and secure your gearbox components and covers in place. Stocked by Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, these studs cover 45-inch Flathead transmissions from 1932 onwards and later Big Twin models. MCS, Samwel and Gardner-Westcott supply replacement studs in chrome, cadmium and zinc finishes that restore damaged or stripped originals. Using the correct stud length and thread pitch is essential for proper assembly torque and prevents the cover distortion that leads to oil leaks and misalignment. Browse the full range below.
