Application Details

This Arnott coil spring conversion kit is engineered for 2015-2020 Cadillac Escalade ESV and 2015-2020 GMC Yukon XL long-wheelbase models. Part number C-4425 is designed for owners replacing a front and rear air suspension system with a conventional steel spring arrangement while maintaining proper electronic system operation through the included bypass module.
