Eibach Spring Perch Adapter - Coilover Spring Seat Adapter

Eibach Spring Perch Adapters are precision suspension hardware components engineered to bridge the gap between metric and SAE coilover spring standards. By expanding the range of compatible spring rates and sizes, these adapters give performance builders, racers, and enthusiasts far greater flexibility when configuring custom coilover and shock absorber setups.

Key Features:

• Expanded spring compatibility — enables the use of U.S. standard SAE springs on coilovers originally designed for metric springs, broadening available spring rate and size options
• CNC precision-machined construction for exact fitment, consistent spring seating, and long-term durability under demanding suspension loads
• Lightweight anodized aluminum — corrosion-resistant and engineered to minimize unsprung weight without sacrificing strength
• Proper spring seating and retention — prevents spring walk, eliminates noise, and reduces premature wear on coilover components across the full range of suspension travel
• Compatible with Eibach coilover systems and select aftermarket shock absorbers across a variety of suspension configurations
• Available in multiple configurations to suit different spring bore diameters and perch combinations
• Backed by Eibach's global quality standards — manufactured to the same rigorous engineering specifications that have made Eibach a trusted name in professional motorsport and OEM supply worldwide

Eibach's production technology is recognized internationally as a benchmark in its field, with all components subject to a strict quality control system certified to EN ISO 9001 and QS9000 international standards. Spring Perch Adapters carry that same commitment to precision engineering — a reliable hardware solution for performance enthusiasts, professional suspension builders, and motorsport teams who demand accuracy and confidence from every component in their setup.
