Carli Suspension Performance 2.5 System | 2014–2018 Ram 1500 EcoDiesel 4WD

Is This for You?

• You're on a 2014–2018 Ram 1500 EcoDiesel 4WD and you need a coilover system valved and sprung specifically for the 3.0L diesel engine weight distribution — not a HEMI tune, not a Pentastar tune, an EcoDiesel-specific spring rate and damper calibration.
• You want King 2.5" Remote Reservoir coilovers up front and King 2.5" Piggyback rears with 17-4 stainless shafts, 10" of front travel, and 13" of rear travel on the DS platform.
• You do NOT have factory 4-corner air suspension — this system is incompatible with air-ride equipped trucks. Verify your suspension type before ordering.

The Result

• 2.0" front lift / 0.75" rear lift — 10" front wheel travel / 13" rear wheel travel.
• King 2.5" Remote Reservoir coilovers with 17-4 stainless shafts — EcoDiesel-specific linear rate front coils and Carli-tuned valving for the 3.0L diesel chassis weight distribution.
• Multi-rate rear coil springs matched to King 2.5" Piggyback rears — includes rear track bar drop bracket and extended sway bar end links for correct geometry at lift height.

The 2014–2018 Ram 1500 EcoDiesel carries meaningfully more front axle weight than the HEMI or Pentastar variants — the 3.0L diesel engine and its associated hardware shift the front weight distribution enough that a HEMI-spec spring rate will sit too high and a HEMI-spec damper tune will be too soft under the diesel's front load. Carli's EcoDiesel-specific calibration addresses this directly: the linear rate front coils are spec'd for the diesel chassis weight, and the King 2.5" Remote Reservoir valving is mapped to that spring rate. Running this system on a HEMI or Pentastar Ram 1500 will produce an oversprung front end that sits higher than advertised and rides harshly — this is an engine-specific SKU, not a universal Ram 1500 fitment. The King 2.5" Remote Reservoir coilover provides more oil volume than a standard 2.0" unit, raising the thermal ceiling before fade onset under repeated off-road impacts. The 17-4 stainless steel shafts offer higher tensile strength than standard chrome-moly and significantly better corrosion resistance in high-moisture environments. Carli strongly recommends the Uniball Upper Control Arms (CS-RAM15UCA-09, sold separately) — without UCAs, the factory rubber ball joint binds at the increased droop angle produced by 2.0" of lift, restricting down-travel and placing alignment geometry outside OEM spec.

Verified Fitment

✔ 2014–2018 Ram 1500 4WD — 3.0L EcoDiesel ONLY

✘ Does NOT fit: Ram 1500 HEMI — spring rates and damper valving are EcoDiesel chassis weight specific; will sit too high and ride poorly on HEMI
✘ Does NOT fit: Ram 1500 Pentastar (V6) — incompatible spring and damper tune
✘ Does NOT fit: Ram 1500 with factory 4-corner air suspension — verify suspension type before ordering
✘ Does NOT fit: Ram 1500 2WD models
✘ Does NOT fit: 2019–2026 Ram 1500 DT (New Body) — different platform geometry; see DT-specific SKU
✘ Does NOT fit: Ram 2500/3500 — incompatible platform

Installation Notes

• Carli strongly recommends Uniball UCAs (CS-RAM15UCA-09, sold separately). Without UCAs, factory rubber ball joint binds at increased droop angle, restricting down-travel and placing alignment geometry outside OEM spec.
• Not compatible with factory 4-corner air suspension. Verify suspension type before ordering.
• Engine-specific valving — do not install on HEMI or Pentastar models.
• Full front-end alignment mandatory post-installation.
• Torque all fasteners to Carli specification. Re-torque all suspension fasteners at 500-mile break-in interval.

Engineering Question: Are you running the 3.0L EcoDiesel on a 2014–2018 Ram 1500 4WD with coil spring (non-air) suspension? This is an engine-specific SKU — spring rates and damper valving are calibrated for EcoDiesel chassis weight distribution only. Also confirm whether you are sourcing the Carli Uniball UCAs (CS-RAM15UCA-09) — down-travel and alignment geometry depend on it.
