Carli Suspension Performance 2.5 System | 2019–2026 Ram 1500 Standard Trims 4WD

Is This for You?

• You're on a 2019–2026 Ram 1500 standard trim — Big Horn, Laramie, Limited, or Lone Star — running stock configuration without RamBox, Multi-Function Tailgate, or a constant bed load. This SKU uses standard-load rear springs calibrated for the unloaded DT standard-trim platform.
• You want King 2.5" Remote Reservoir coilovers up front and King 2.5" Piggyback rears with Carli-fabricated Uniball UCAs, 17-4 stainless shafts, 9" of front travel, and 12" of rear travel.
• You are NOT on a Rebel or Off-Road Group trim and you do NOT have factory 4-corner air suspension — Rebel and Off-Road Group trucks have a factory 1" lift and a different front coil perch height that requires a separate SKU (CS-RAM15PERF25-RBL-19). Air-ride trucks are incompatible.

The Result

• 2.5" front lift on HEMI / 2.0" front lift on EcoDiesel / 1.0"–1.25" rear lift — 9" front wheel travel / 12" rear wheel travel.
• King 2.5" Remote Reservoir coilovers with 17-4 stainless shafts and Carli Uniball UCAs — full 9" down-travel requires the included UCAs; factory UCAs bind at the increased droop angle produced by 2.5" of lift.
• Standard-load multi-rate rear springs matched to King 2.5" Piggyback rears — calibrated for the unloaded DT standard-trim platform, not the Rebel perch geometry or HD load rating.

The lift height differential between HEMI and EcoDiesel on this SKU — 2.5" vs. 2.0" — reflects the difference in front axle weight between the two engine configurations. The 3.0L EcoDiesel carries more front axle weight than the HEMI, which compresses the front coils further at static ride height, resulting in a lower net lift figure from the same spring. This is not a tuning compromise — it is the correct outcome of a spring rate calibrated for the standard-trim DT platform across both engine variants. The Carli Uniball UCAs (CS-RAM15UCA-09) are included and required: the factory Ram 1500 UCAs use a rubber ball joint that binds at the increased droop angle produced by 2.5" of lift, restricting down-travel and placing alignment geometry outside OEM spec. The Uniball replaces that rubber joint with a zero-bind spherical bearing. The King 2.5" Remote Reservoir coilover provides more oil volume than a standard 2.0" unit, raising the thermal ceiling before fade onset. The 17-4 stainless steel shafts offer higher tensile strength than standard chrome-moly and significantly better corrosion resistance. Standard-trim DT trucks have a lower front coil perch than Rebel/Off-Road Group trucks — the spring rate and coilover length in this SKU are spec'd for that lower perch. Installing this system on a Rebel or Off-Road Group truck will produce incorrect lift height and geometry.

Verified Fitment

✔ 2019–2026 Ram 1500 4WD — Big Horn, Laramie, Limited, Lone Star (Standard Trims)
✔ Engine Compatibility: 5.7L Hemi | 3.6L Pentastar | 3.0L EcoDiesel

✘ Does NOT fit: Ram 1500 Rebel or Off-Road Group — different front coil perch height; order CS-RAM15PERF25-RBL-19
✘ Does NOT fit: Ram 1500 with factory 4-corner air suspension
✘ Does NOT fit: Trucks with RamBox, Multi-Function Tailgate, or constant ~500 lb bed load — order HD SKU (CS-RAM15PERF25-RBL-19-HD)
✘ Does NOT fit: Ram 1500 2WD models
✘ Does NOT fit: 2014–2024 Ram 1500 Classic (DS platform) — different suspension geometry
✘ Does NOT fit: Ram 2500/3500 — incompatible platform

Installation Notes

• Uniball UCAs (CS-RAM15UCA-09) are included and required for full 9" front travel. Do not install without UCAs — down-travel will be restricted and alignment geometry will fall outside spec.
• Front braided brake lines (CS-RAM15BBL-19) must be installed with the front coilovers — factory lines do not have sufficient length at full down-travel.
• Verify trim level before installation. Standard-trim DT trucks have a lower front coil perch than Rebel/Off-Road Group — installing on a Rebel will produce incorrect lift height and geometry.
• Full front-end alignment mandatory post-installation. UCA geometry change affects caster and camber.
• Torque all fasteners to Carli specification. Re-torque all suspension fasteners at 500-mile break-in interval.
• Factory wheels are compatible with stock tires only — larger-than-stock tires will contact Carli UCAs on factory wheels.

Engineering Question: Is your Ram 1500 a standard trim (Big Horn, Laramie, Limited, or Lone Star) with coil spring (non-air) suspension, running without RamBox or Multi-Function Tailgate? Also confirm your engine — HEMI vs. EcoDiesel — as front lift height differs between the two. If you are on a Rebel or Off-Road Group, this SKU does not fit.
