914Rubber Side Shift Transmission Friction Ring at Firewall for Porsche 914 (1973-76)
Refine your Porsche 914’s shifting precision with the 914Rubber Side Shift Transmission Friction Ring at Firewall, crafted for 1973-76 models with side-shift 901 or 915 transmissions. PMB Performance, with 20 years of Porsche expertise, is the leading 914Rubber retailer, selling more of their SKUs than anyone else. Our nearly two-decade partnership with 914Rubber ensures you get OEM-quality parts backed by hands-on technical knowledge.
This OEM reproduction friction ring (Part #914.424.224.01) mounts at the firewall, guiding the shift rod to eliminate play in the side-shift linkage. Made from high-durability urethane, it offers low friction and resists wear, unlike degraded originals that cause sloppy or imprecise gear changes. PMB Performance has installed these in numerous 914 rebuilds, with customers reporting, “Shifting is smooth and exact, like a factory-fresh 914!” One ring is required per car, ensuring a secure fit at the firewall pass-through.
Why this part? A worn firewall friction ring allows excessive shift rod movement, leading to vague shifts or grinding, especially in 914s where mid-engine dynamics amplify linkage stress. This ring restores tight, responsive gear engagement, critical for side-shift setups. It’s a direct-fit replacement, requiring no modifications, and complements the transmission-side friction ring (Part #914.424.224.02) for a complete linkage refresh.

Installation requires a 10mm wrench, snap ring pliers, and lithium grease. Access the shift rod at the firewall (under the rear trunk), remove the old ring, and install the new one, ensuring proper seating in the firewall mount. Apply grease for smooth operation and verify rod alignment. Torque any disturbed bolts to 8 Nm. One ring is needed per car, compatible with 1973-76 914 models, including 914-6.
With PMB Performance’s 20 years of Porsche restoration experience and 914Rubber’s precision engineering, this friction ring delivers reliability and performance. Whether you’re upgrading your 914’s shifter or maintaining a side-shift transmission, trust us to keep your Porsche shifting flawlessly. Questions?
