Description

Elevate the look and functionality of your classic 12-valve Cummins with the G&R Diesel Billet Aluminum Individual Valve Cover Kit. These precision-machined covers deliver a premium appearance while providing the practical upgrades serious builders demand for both daily-driven and high-performance applications.

Premium Construction & Materials

CNC-machined from high-quality billet aluminum, each individual valve cover is built for strength, durability, and a clean, professional finish. Approximately 0.250 inches taller than the factory covers, they offer valuable extra clearance for valvetrain components and head studs. The kit includes all-new stainless steel socket head bolts for a secure, corrosion-resistant installation.

Key Features & Benefits

  • Extra Valvetrain & Stud Clearance: Designed with additional height to accommodate upgraded valvetrain setups and common head stud applications (including ARP and A1 studs) without requiring grinding or milling.
  • O-Ring Sealing System: Incorporates modern O-ring seals that completely eliminate the messy, traditional factory valve cover gasket for a cleaner, more reliable, and easier-to-service seal.
  • Individual Cover Design: Separate billet covers for each cylinder bank deliver a distinctive, high-end aesthetic that transforms the appearance of any 12-valve engine bay.
  • Complete Hardware Kit: Includes premium stainless steel socket head bolts for straightforward installation and long-term durability.
  • Versatile Fitment: Suitable for both daily drivers and hot-rodded builds seeking improved clearance and a standout visual upgrade.

Applications

  • 1989–1998 Dodge Ram 5.9L Cummins 12-Valve engines
  • Note: Does not fit 1998.5+ 24-Valve models
