Rocker Box Bolt Kits

23 products

Rocker Box Bolt Kits for Harley-Davidson offers complete bolt sets for securing the rocker box covers to the cylinder heads. A full bolt kit ensures uniform clamping force, proper gasket compression and an oil-tight seal across the rocker box mating surface. Available through Iron City Motorcycles, an authorised Harley-Davidson dealer, this collection features Gardner-Westcott, Colony and MCS. Whether you ride a Sportster, Softail or Dyna with an Evolution, Twin Cam or Milwaukee-Eight engine, you will find bolt kits in chrome, polished stainless and zinc finishes that upgrade the look of your top end. Each kit is model-specific and includes every fastener required for both rocker boxes. Browse the full range below.
