Carli Suspension King 2.5 RR Shock Package | 2013–2022 Ram 3500 Diesel 4WD (2.5" Leveling)

Is This for You?

• You're running Carli leveling springs on a 2013–2022 Ram 3500 Cummins and need the matched King 2.5" Remote Reservoir shock package — front and rear damping spec'd to the Carli leveling spring rates, not a generic shock tune.
• You want King 2.5" Remote Reservoir shocks front and rear with Carli-specific valving for the Cummins diesel platform weight — not a gas-engine tune running in the wrong application.
• You're on a SRW Ram 3500 — this package is geometry-specific to the single rear wheel configuration. DRW (Dually) rear suspension geometry is incompatible.

The Result

• Matched front and rear King 2.5" Remote Reservoir damping — Carli-tuned valving calibrated for 2.5" leveling spring rates on the Cummins diesel platform.
• Remote reservoir canister increases oil volume over a standard 2.0" shock body, extending the thermal ceiling before fade onset under sustained towing and hauling loads.
• Includes reservoir mounting hardware — complete bolt-in package for the 2013–2022 Ram 3500 4WD platform.

The King 2.5" Remote Reservoir shock runs a 2.5" body diameter with a remote reservoir canister connected by a high-pressure hose. The reservoir adds oil volume beyond what the main shock body can hold — directly increasing the thermal ceiling before damping consistency degrades under repeated impacts or sustained towing loads. Carli's valving specification for this package is not a universal King tune — it is mapped to the spring rate curve of Carli's leveling coil springs and calibrated for the front axle weight of a Cummins diesel Ram 3500. Running this shock package against non-Carli springs or on a gas-engine Ram will produce a damping ratio that does not match the spring rate, degrading both on-road compliance and load control. The package includes reservoir mounting hardware specific to the 2013–2022 Ram 3500 platform — this is a complete shock package, not bare shocks requiring separate mount sourcing. The 2013–2022 application window covers the DJ/D2 platform Ram 3500; the 2023+ Ram 3500 moved to a revised platform architecture and is not covered by this SKU.

Verified Fitment

✔ 2013–2022 Ram 3500 4WD — Cummins Diesel SRW

✘ Does NOT fit: Ram 3500 Gas engines — valving calibrated for Cummins diesel front axle weight
✘ Does NOT fit: Ram 3500 DRW (Dually) — rear suspension geometry incompatible with SRW shock package
✘ Does NOT fit: 2WD Ram 3500
✘ Does NOT fit: 2023–2026 Ram 3500 — revised platform architecture; different shock geometry
✘ Does NOT fit: 2012 and earlier Ram 3500 — different suspension platform
✘ Does NOT fit: Ram 2500 — different spring rates and shock geometry; see Ram 2500-specific SKU
✘ Does NOT fit: Trucks running stock-height springs or non-Carli leveling springs — valving is matched to Carli leveling spring rates

Installation Notes

• Requires Carli leveling springs. Shock valving is matched to Carli spring rates — running against non-Carli springs will produce unbalanced damping.
• Install reservoir mounting hardware per Carli specification. Verify reservoir hose routing clears all suspension components through full travel before finalizing.
• Full front-end alignment recommended post-installation if springs are being installed simultaneously.
• Torque all fasteners to Carli specification. Re-torque at 500-mile break-in interval.

Engineering Question: Are you running Carli leveling springs on a 2013–2022 Ram 3500 Cummins 4WD SRW? This shock package is valved specifically for Carli spring rates on the Cummins platform — confirm your spring configuration and model year before ordering. If you are on a 2023+ Ram 3500 or a DRW, this package does not fit.
