Eibach ERS 2.50 in. ID Progressive Tender Spring

When you're rebuilding your coilover setup or looking to fine-tune your suspension's initial response, a progressive tender spring can make a notable difference. This Eibach ERS spring is designed to work with 2.50-inch inner diameter coilover systems, offering a specific spring rate that helps manage the suspension's initial travel before the main spring takes over. It’s a well-built component that helps smooth out the ride over small imperfections and can improve overall handling by keeping the main spring seated and ready to react.

This particular tender spring has a free length ranging from 0.25 inches to 0.425 inches, giving you a bit of flexibility depending on your specific setup needs. Eibach is known for its spring manufacturing, and this part continues that reputation with solid construction. It's a popular choice for those who understand the nuances of suspension tuning and want to achieve a more refined feel from their vehicle's handling.
