Vehicle Fitment

• 2014-2024 Ram ProMaster 1500 (Cargo Van, Window Van, Cutaway, FWD, 3.6L Pentastar V6)
• 2014-2017 Ram ProMaster 1500 (Cargo Van, Window Van, Cutaway, FWD, 3.0L EcoDiesel I4)
• 2014-2024 Ram ProMaster 2500 (Cargo Van, Window Van, Cutaway, FWD, 3.6L Pentastar V6)
• 2014-2017 Ram ProMaster 2500 (Cargo Van, Window Van, Cutaway, FWD, 3.0L EcoDiesel I4)
• 2014-2024 Ram ProMaster 3500 (Cargo Van, Window Van, Cutaway, FWD, 3.6L Pentastar V6)
• 2014-2017 Ram ProMaster 3500 (Cargo Van, Window Van, Cutaway, FWD, 3.0L EcoDiesel I4)

Fitment Notes

• Fits Ram ProMaster models with Leaf Spring rear suspension only - OEM eye-to-eye extended length 469mm (LMax 469mm / LMin 307mm)
• Does NOT fit Ram ProMaster models equipped with Torsion Bar rear suspension - those require a different KONI part number
• Does NOT fit Ram ProMaster City (smaller platform, unrelated suspension)
• The 3.0L EcoDiesel I4 engine was discontinued after the 2017 model year; 2018-2024 ProMasters use the 3.6L Pentastar V6 exclusively
• Sold as 1 shock absorber - recommend replacing in axle pairs for optimal performance and balanced handling

Features

• KONI Special Active technology utilizes the latest generation of Frequency Selective Damping (FSD), automatically adjusting damping force based on real-time road conditions without electronics
• Controls large body motions, cornering forces, pitching, and swaying while simultaneously smoothing out expansion joints and rough road surfaces for improved comfort
• Provides superior ride quality improvement over factory OEM shocks, which are widely known to be too soft for loaded or upfitted ProMaster applications
• Electronics-free adaptive damping technology - delivers performance rivaling expensive OEM electronic damping systems at a fraction of the cost, and can be retrofitted to any ProMaster in the fitment range
• Proven technology factory-fitted on over 10 million vehicles worldwide, including platforms from Alfa Romeo, Mercedes-Benz, Jeep, Fiat, and Lamborghini
• Engineered specifically for the unique weight distribution and load dynamics of full-size commercial vans, camper vans, and upfitted ProMaster builds
• Reduces noise, harshness, and banging associated with hard roads, unpaved surfaces, and commercial driving conditions
• Improves overall vehicle safety and road holding by reducing body roll and enhancing stability during cornering, braking, and acceleration
• Designed to work in paired conjunction with KONI's 8705-1332 FSD front struts for a complete, balanced suspension upgrade across both axles

Product Description

The KONI 8205-1006 Special Active Rear Shock Absorber is a direct-fit, performance-grade replacement for the rear suspension on 2014-2024 Ram ProMaster 1500, 2500, and 3500 vans equipped with leaf spring rear suspension. One of the most consistent criticisms of the ProMaster platform has been that the factory shock absorbers are too soft for real-world commercial, fleet, and camper van use - often resulting in excessive body roll, instability under load, and the van riding on its bump rubbers when converted or upfitted. The KONI 8205-1006 solves this directly by replacing the OEM damper with KONI's patented Frequency Selective Damping technology, which automatically and continuously adapts the damping rate to road conditions in real time - all without any electronic sensors, wiring, or calibration required.

KONI's Special Active FSD technology works by sensing the frequency of suspension inputs: it stiffens damping during large-amplitude movements like body roll, cornering loads, and pitching - while simultaneously remaining compliant over small, high-frequency inputs like rough pavement, expansion joints, and washboard surfaces. The result is a single shock that delivers the best of both worlds - sharp, controlled handling for the driver and a smooth, comfortable ride for passengers and cargo alike. This is the same foundational technology that KONI supplies as factory-fitted equipment to multiple global OEMs, and it is proven on over 10 million vehicles worldwide. When paired with KONI's 8705-1332 FSD front struts, the 8205-1006 completes a full-system suspension upgrade that transforms the ProMaster's ride and handling dynamics.

Installation is straightforward for any technician familiar with full-size van suspension service, and the 8205-1006 is confirmed to fit all three ProMaster series (1500, 2500, and 3500) across all available body styles - cargo van, window van, and cutaway - as long as the vehicle is equipped with the standard leaf spring rear suspension at an OEM extended length of 469mm. Vehicles with the torsion bar rear suspension configuration require a different part number and are not compatible with this shock. For best results and to maintain balanced axle damping, KONI recommends replacing rear shocks in pairs. This shock is sold as a single unit.
