The Parts Landscape
The Land Rover air suspension aftermarket has grown significantly over the past decade. You'll encounter four tiers: OEM Land Rover/Range Rover parts sourced through dealers or authorized distributors; Dunlop parts (the original OEM air bag supplier — their bags go into the vehicles at the factory); Arnott Industries (the largest dedicated air suspension aftermarket manufacturer, US-based, with a warranty and track record); and generic/unbranded parts sold through Amazon and eBay at prices that look compelling until you're replacing them again 14 months later.
