Gardner-Westcott Harley Transmission Top Cover Screw Kit 041626 C-74-38 NOS

Description

Unlike standard factory hex bolts that protrude from the housing or low-grade screws that easily strip, these premium fasteners feature a specialized countersunk tapered head configuration designed to sit completely flush with the top cover surface. Engineered for specialized powertrain applications, this custom hardware distributes clamping force uniformly across your gearbox lid mating surfaces. This mechanical positive-torque setup prevents structural fluid leaks and fluid weeping around the shifting mechanism, shielding your aluminum transmission casing threads from stripping out and protecting your drivetrain internals from terminal oil loss on the road.

  • Brand: Gardner-Westcott Company (Premium High-Performance Aftermarket Restoration Core)
  • Component Type: Transmission Shifter Top Cover Countersunk Fastener Hardware Kit
  • Total Kit Volume Sizing: 8-Piece Mechanical Fastener Lot (Complete Top Lid Set)
