Air suspension offers a smooth, level ride—but as components age, replacement becomes necessary. For older vehicles or persistent air system issues, Arnott’s coil spring conversion kits provide a reliable, maintenance-free alternative. Built from US-made steel, they install easily with no modifications required.

If you frequently tow or haul heavy loads, though, air suspension may be the better choice—its auto-leveling feature maintains proper ride height and handling, something coil springs can’t replicate.

Electronic Bypass Module

Included in many of Arnott’s Coil Spring Conversion Kits, Arnott’s exclusive Electronic Bypass Module (U.S. Pat.
