22RPD Next Gen Copper Headgasket Spacer

Refined Through Experience. Built for Performance.

For over a decade, we’ve been installing copper headgasket spacers with great success. After years of real-world use, we’ve taken our experience and refined the design to create the Next Gen Copper Headgasket Spacer—an improved version with updated fitment and durability.

Key Features:

• C110 Copper Construction – Made from 99.9% pure copper, ensuring excellent thermal transfer and durability.
• Optimized Thickness – 0.063” (1.6mm) thick, bringing final compression to ~9:1 when used with our 0.079” cutring headgasket.
• H2 Annealed for Stability – Pre-annealed to H2 hardness, offering a balance between longevity and ease of maintenance. This requires less retorquing than H0 soft copper but does need a clean, flat sealing surface for optimal results.
• Optional H0 Annealing – For those who prefer matching the typical gasket softness, we offer annealing to H0 hardness for an additional $50, ensuring a more forgiving seal on less-than-perfect surfaces.
• Updated for 11mm Studs – Now designed to clear 11mm studs, while still fully compatible with 10mm studs.
• Available in Multiple Bore Sizes – Offered for M50, M52, S50, and S52 engines, plus oversized bore options for custom applications.
