RNB501580 Air Suspension Shock Strut for Land Rover  Discovery 3 (2005-2009)  Range Rover Sport (2005-2012)

OE RNB501580 is a classic low-spec front air strut for Land Rover L319/L320 platform. It is specially designed for Discovery 3, Discovery 4 and old Range Rover Sport equipped with basic air suspension without ADS adaptive damping. This is a purely mechanical air strut with no solenoid valve and no electronic signal. It is one of the most widely replaced vulnerable air suspension parts for old Land Rover off-road SUVs. The original factory released multiple revised batches with various alternative OE numbers. All interchangeable models share identical mounting dimensions, stroke, air spring pressure rating and damping force. It can be fitted on both front sides without distinction, featuring great versatility and reducing inventory pressure.

Land Rover Discovery 3/4 and Range Rover Sport have heavy curb weight and large suspension travel for off-road usage. Long-term heavy load, bumpy driving and repeated compression & extension will easily cause typical failures. The rubber air spring ages and cracks, resulting in air leakage, front end sag, uneven body height, tilted vehicle posture after overnight parking. Degraded hydraulic oil and failed oil seals lead to excessive bounce over potholes, loose chassis, poor high-speed stability and insufficient support during lane change. For low-spec non-ADS vehicles, air strut failure will not trigger complex electronic fault codes, but directly cause collapsed body posture and terrible ride quality. Continuous driving with faulty strut will accelerate uneven tire wear and damage of chassis bushes and control arms, bringing high maintenance cost.

Our RNB501580 front air strut is 1:1 moulded strictly according to original L319/L320 OE specification. Tuned for heavy load, rough road and long-travel off-road chassis. It adopts multi-layer imported explosion-proof rubber air spring with excellent high & low temperature resistance, anti-rust solid piston rod, multi-stage high pressure sealing structure and long-life heavy-duty hydraulic oil to prevent air leakage and damping failure caused by long-time bumpy driving. Every unit is 100% tested for air tightness, high & low temperature endurance and heavy-load fatigue impact to avoid micro air leakage and insufficient damping. It is a complete pre-assembled unit, universal for front left and front right. Direct bolt-on installation without modification or programming. After installation, simply inflate and calibrate vehicle height to restore factory-standard body posture and tight chassis performance. Low return rate, ideal for garage repair, auto parts stocking and cross-border export.
