GFB 6116 – Softer Main Piston Spring

The GFB 6116 Softer Main Piston Spring is designed to provide lighter spring tension in GFB blow-off valves, improving response in specific engine conditions.

🔧 Key Features & Benefits

• Fits all Mach 2, Respons TMS, and Deceptor Pro II valves
• Softer spring tension – Provides smoother operation under low vacuum conditions
• Supplied standard in fully recirculated Mach 2 valves
• Compatible with Respons TMS and Deceptor Pro II valves when fully recirculated
• Optimized for engines with idle vacuum below 19”Hg

⚙️ Usage Notes

• Fully Recirculated Setup: Recommended for Mach 2, Respons TMS, and Deceptor Pro II valves
• Atmosphere Venting: If engine idle vacuum is over 19”Hg, use the standard spring 6115 instead
• Ensures proper valve response without over-opening at idle
