2019-2025 Ram 1500 Shocks: A Buyer's Guide to Coil, Air Suspension & Off-Road Variants

Understanding Your 2019-2025 Ram 1500 Suspension Before You Buy

The single most important step in buying a replacement shock absorber for a 2019-2025 Ram 1500 is correctly identifying the suspension system your truck is equipped with. Unlike older trucks with one-size-fits-all options, the modern DT-platform Ram 1500 has several distinct, non-interchangeable suspension setups. Choosing the wrong part will result in wasted time, money, and a part that simply will not fit.

Suspension System Variants

Before purchasing, you must determine which of these systems your truck has:

• Standard Coil Suspension: This is the base system. It uses a coil spring and a separate, conventional shock absorber at each rear wheel. The front uses a coilover strut assembly (where the coil spring is mounted over the strut). These are simple, reliable, and the least expensive to replace.
• Active-Level™ Four-Corner Air Suspension: This is an optional factory system. It replaces the traditional coil springs and shocks with integrated air spring/shock assemblies, often called air struts. These are electronically controlled to adjust ride height for entry/exit, aerodynamics at speed, and load leveling. They are identifiable by the 'Up/Down' ride height buttons on the center console and will display a "Service Air Suspension" message on the dash 🎬 See how to troubleshoot and fix Ram air suspension issues if there's a problem.
• Off-Road Package (e.g., Rebel, 4x4 Off-Road Group): Trucks with these packages come with upgraded shocks from the factory, often supplied by Bilstein. These shocks are designed for better heat dissipation and control in demanding off-road conditions. They are physically larger and more robust than the standard shocks. The OEM part numbers 68262589AC and its successor 68262589AD are for these rear off-road package shocks.

Most Common Symptoms of Failure

How you know your shocks are failing depends heavily on which suspension system you have.

For Standard Coil & Off-Road Package Shocks:

• Bouncy, Uncontrolled Ride: After hitting a bump, the truck continues to bounce up and down instead of settling immediately. This is the classic sign of a worn-out shock.
• Nose-Dive and Squat: The front of the truck dips excessively during braking, or the rear squats significantly during acceleration.
• Fluid Leaks: A visible film of oily fluid on the outside of the shock body indicates that the internal seals have failed and hydraulic fluid is escaping. A leaking shock is a failed shock.
• Unusual Noises: A clunking or knocking sound from the suspension area when going over bumps can point to worn shock mounting bushings or a loose shock.
• Uneven Tire Wear: Worn shocks can cause a specific type of tire wear called "cupping" or "scalloping," where patches of tread are worn down in uneven spots. This happens because the tire is literally bouncing off the pavement as you drive.

For Active-Level™ Air Suspension:

• "Service Air Suspension" Message: This warning on the instrument cluster is your first and most obvious clue that the system has detected a fault.
• Vehicle Sagging: One or all corners of the truck sit lower than normal, especially after being parked overnight. This indicates a leak in an air spring or air line.
• Compressor Runs Constantly: If the air compressor is trying to compensate for a leak, you may hear it running much more frequently than usual, or for extended periods after starting the truck.
• Hissing Sounds: A faint hissing noise from a corner of the vehicle when parked can indicate a small air leak.

Known Issues, TSBs, and Recalls

While no major safety recalls exist for the shocks themselves, Ram has issued several Technical Service Bulletins (TSBs) related to the suspension systems:

• TSB 08-009-21: This addresses a software issue in the Active Level Air Suspension (ALAS) Control Module that could cause a false "Service Air Suspension" message. The fix is a software flash performed by a dealer.
• TSB 17-003-21 & 17-002-21: These bulletins address clunking noises from the left or right rear shock area on some 2021 models, resolved by replacing the affected shock absorber.
• TSB 02-004-22: For 2021-2022 Ram 1500 TRX models, this TSB addresses a condition where the vehicle leans to the left, fixed by replacing the left front and rear springs.

Buying a Used Suspension Shock Absorber

Purchasing a used shock absorber can be a smart way to save money, especially for the expensive air suspension components. However, you must be a careful shopper.

What to Physically Inspect:

• Check for Leaks: This is the number one red flag. Wipe the shock body with a clean rag. If it comes away oily and grimy, the shock's seals are blown. Do not buy it.
• Inspect the Rod: The shiny piston rod that extends from the shock body should be perfectly smooth and free of pits, rust, or scratches. Any damage to this surface will quickly destroy the new seal and cause it to fail.
• Examine the Body: Look for major dents or deep scrapes on the shock's main body. A significant dent can interfere with the internal piston's movement.
• Check the Mounts: Ensure the mounting loops or studs are not bent, cracked, or excessively worn. The rubber or metal bushings should be intact.
• For Air Suspension: Carefully inspect the rubber air spring bladder for any cracks, chafing, or signs of dry rot. Check the electrical connectors for bent or corroded pins and ensure the air line fitting is clean and undamaged.

Compatibility and Mileage:

• Verify the Part Number: Match the OEM part number on the used shock to your original part or the number specified for your truck's VIN and suspension type.
• Mileage Matters: Shocks are a wear item. A used shock from a truck with 30,000 miles is a great value. One from a truck with 150,000 miles is likely near the end of its life. Aim for parts from vehicles with under 75,000 miles if possible.
• Why Used OEM is a Good Choice: For the complex Active-Level™ air struts, a low-mileage used OEM unit is often a more reliable and affordable alternative to a brand new OEM part, which can be prohibitively expensive. For standard shocks, used OEM guarantees the factory ride quality, which some aftermarket parts fail to replicate.

Replacement Information

Installation difficulty varies dramatically depending on the location and type of shock.

• Rear Shocks (Standard & Off-Road): This is a very straightforward job, often requiring only a couple of wrenches and sockets. The shock is typically held in by just two bolts.

• Front Struts (Standard & Off-Road): This is a much more involved and potentially dangerous job. It requires disassembling a significant portion of the front suspension. The coil spring is under extreme tension and requires a special spring compressor tool to safely remove. Many DIY mechanics opt to buy a complete "quick strut" assembly to avoid this step. An alignment is recommended after replacement.
• Air Suspension Struts: This is also an advanced job. It requires safely depressurizing the system before removal and ensuring air lines and electrical connections are handled correctly upon reinstallation. An alignment is also recommended.

Cost Breakdown

Prices can vary significantly based on suspension type and where you buy the parts.
