Tired of your BMW sagging in the driveway or facing recurring "Suspension Leveling" errors? The Arnott C-5689 Coil Spring Conversion Kit is the ultimate "fix-it-and-forget-it" upgrade for BMW X5 and X6 owners. This kit swaps out your complex, leak-prone rear air bags for high-strength steel springs made right in the USA. Designed for owners who value long-term reliability over the adjustable nature of air suspension, this kit delivers a consistent, comfortable ride that closely mimics the original feel of your BMW. It is the most reliable way to restore your SUV's stance and your own peace of mind.
Key Features
Reliability Upgrade: Replaces air springs that are prone to leaking and dry-rotting.
Cost Savings: Typically costs significantly less than a single air suspension repair at a dealership.
Complete Kit: Includes everything needed—springs, isolators, and the EBM module.
User-Friendly Installation: Can be installed by a qualified mechanic in a few hours with standard tools.
Consistent Performance: Unlike air systems that can fluctuate, coil springs provide the same support every time you drive.
