Q1: Which vehicles does this fit? Cadillac Escalade IV (2015–2020), Chevrolet Suburban / Tahoe and GMC Yukon with factory air suspension and Magnetic Ride, per the supplier table. Catalog fitment: Escalade 2014–2020, Suburban 2018–…, Tahoe 2018–… — confirm the exact model and year by VIN.
Q2: Is this a single part for both rear sides? The supplier table lists this OE as "Rear" (left & right). For these K2XX SUVs the rear air struts are installed per side — confirm the side and stamped number by VIN when ordering.
Q3: Is this the Magnetic Ride version? Yes — this product is the WITH Magnetic Ride Control (MRC) version, confirmed by the user and verified by catalog data ("for vehicles with Magnetic Ride", monotube damper). Do NOT fit it to a non-MRC vehicle.
Q4: Is this the complete strut or just the air spring? The complete assembly — air spring (bellows) + monotube Magnetic Ride shock absorber integrated in one unit (top eye / bottom eye), ready to install as a direct replacement.
Q5: Does this strut have electrical damping? Yes — Magnetic Ride Control is electrically controlled (magnetorheological fluid). The strut carries the MRC electrical interface — confirm the connector against the original unit by VIN.
Q6: Do I need to replace both rear sides at the same time? Same-axle pair replacement is strongly recommended; an old unit on the other side causes uneven height and damping behavior.
Q7: What should I pay attention to during installation? Release the air suspension pressure per the workshop manual; protect the air fitting and MRC electrical connector from dirt; after installation let the leveling system re-level and perform the suspension calibration if required by the workshop manual; check both sides' height and leaks before a road test.
Q8: Warranty policy and shipping damage? 18-month warranty under normal use. For shipping damage, inspect within 48 hours of receipt and send photos/video — the seller arranges a replacement.
Q9: Service life and maintenance? Depends on road conditions and climate. Keep the bellows clean and check for cracks during routine service; replace the complete unit if a bellows leak is found.
Q10: Are aftermarket alternatives available? The interchange list for this OE number is available on request. Order by the exact OE number and confirm the model/year, variant and side by VIN.
