Measurement Guidelines
To ensure an accurate fit, measure along the surface of the leaf spring. Note that eye-to-end measurements may vary over time due to the spring flattening with use. If you have any questions, contact the experts at Spring Works for assistance or open our chat for AI responses to common questions.
