Cylinder Base Nut Kits

13 produits

Cylinder Base Nut Kits for Harley-Davidson supply the complete set of fasteners needed to secure your cylinders to the crankcases, ensuring a uniform, leak-free seal. Stocked by Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, our range features kits from Colony, Gardner-Westcott, and James Gaskets. These kits are designed for Big Twin, Evo, Shovelhead, and Panhead engines in Softail, Dyna, and Touring models. Fresh base nuts and washers should always be used during a top-end rebuild, as reusing stretched or corroded fasteners risks uneven clamping and gasket failure. Browse the full range below.
