4877147AH Front Air Suspension Shock Dodge RAM 1500 Assembly With Height Control

Q1: Is this the left or right front strut? The supplier table lists 4877147AH as the Front unit without left/right split. The 4877146 and 4877147 series form the front left/right pair (catalog data lists both series under the same front unit) — confirm the exact side by the stamped OE number on your original unit and by VIN.

Q2: Which vehicles does this fit? RAM 1500 (2009–2019) with factory air suspension, per the supplier table. Note that air suspension was introduced from the 2013 model year on this platform; European catalog data lists RAM 2008–… for this front air strut; 2019+ next-generation models use a different numbering system — confirm the exact model and year by VIN.

Q3: What is the difference between the 4877146 and 4877147 series? They are the two front-axle series of the same air strut (catalog data lists both under one front unit) — i.e., the left/right pair. Match your original unit's stamped number.

Q4: Is this the complete strut or just the air spring? The complete assembly — air spring (bellows) + shock absorber integrated in one unit (top yoke / bottom fork), ready to install as a direct replacement.

Q5: Does this strut have electrical damping? The factory RAM air suspension provides ride-height control and leveling; the supplier table does not indicate electronically controlled damping for this unit. Confirm the presence of a damping connector against the original unit by VIN.

Q6: Do I need to replace both front sides at the same time? Same-axle pair replacement is strongly recommended; an old unit on the other side causes uneven height and leveling behavior.

Q7: What should I pay attention to during installation? Release the air suspension pressure per the workshop manual; protect the air fitting and electrical connector (if fitted) from dirt; after installation let the height control system re-level; 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, axle and side by VIN.
