914Rubber Seat Adjuster Rebuild Kit for Porsche 914 (1970-76)
Restore smooth, precise seat adjustment to your Porsche 914 with the 914Rubber Seat Adjuster Rebuild Kit, designed for all models (1970-76) and available through PMB Performance. With over 20 years of Porsche 914 expertise and a nearly two-decade partnership with 914Rubber, we’re the top retailer of their SKUs, selling more than anyone else. This kit includes durable components to overhaul your seat adjuster mechanism, ensuring factory-correct operation and interior comfort.
Kit Components:
- Seat Adjuster Handle (Part #914.521.029.10, 2 pieces): Reproduction handles made from powder-coated steel, replacing brittle or cracked OEM plastic handles. Secured with M6 allen machine screws, these handles are guaranteed not to break, unlike original pot metal versions. Two required per car (one per seat). Note: Fasteners are metric M6, not 1/4-20, for OEM compatibility, though they may sit 1-2mm proud when installed, which may slightly affect locking function for concours purists.

- Seat Track Springs (Part #914.521.815.10, 4 pieces): High-tensile steel springs that maintain track tension for smooth fore-aft adjustment. These replace worn or fatigued springs that cause sloppy seat movement. Two springs per track, four per car.
- Track Guide Bushings (Part #914.521.817.10, 4 pieces): Reproduction nylon bushings that reduce friction and wear in the seat tracks. These ensure precise sliding motion and prevent binding, a common issue we’ve seen in our shop with degraded bushings.
- Mounting Hardware (Part #N.014.131.1, 8 pieces): Stainless steel M6 allen screws and washers for securing handles and tracks. Corrosion-resistant for long-term durability, unlike rusted OEM fasteners.
Technical Details: Compatible with all Porsche 914 model years (1970-76), this kit rebuilds the seat adjuster mechanism for both driver and passenger seats. The steel handles improve durability over OEM plastic, though they may not be exact reproductions for concours restorations. Installation requires removing the seat; clean tracks with degreaser and lubricate with white lithium grease for optimal sliding. Torque screws to 8-10 Nm to avoid stripping. For a complete interior refresh, pair with 914Rubber’s Seat Upholstery Tab Kit (Part #914.521.819.10). One kit per car (covers both seats). If tracks are heavily worn, inspect the seat frame for alignment issues.
