EFS MRP 2.5 Rear Shock Absorber, 50 mm Lift - RAM 1500 DT from 2019

A RAM 1500 DT is in its element on the highway. The trouble starts on gravel and forest tracks: the long wheelbase, the mass and comfort-biased factory damping leave the rear floating and pumping instead of working.

The MRP 2.5 rear damper changes that. It lifts the rear by 50 mm, cools the oil in a finned remote reservoir and lets you set compression and rebound separately, rather than living with one factory compromise.

Key benefits

• Remote finned reservoir - the oil has somewhere to dump heat, so damping does not vanish after a dozen kilometres of corrugations.
• 24 compression and 36 rebound clicks - 60 settings instead of one factory compromise.
• Monotube with an oversized shaft - more working area and calmer behaviour at full load.
• Rebuildable construction - the damper was designed to be serviced, not replaced.
• Bonded rubber bushes and a shaft boot come with every unit.

What is in the box

• MRP 2.5 damper with a hose-mounted remote reservoir
• rubber shaft boot
• steel reservoir bracket
• hose clamps and mounting hardware
• instruction sheet with the registration QR code

The listing covers one damper. A complete axle needs two.

Who it is for

For RAM 1500 DT owners who genuinely use the tray and the tow bar: hauling gear, pulling a trailer, or covering enough unsealed road that the factory dampers start to give up. It also suits trucks carrying a camper build.

Fitting and tuning

Damping is set with two knobs: 24 clicks of compression and 36 clicks of rebound. Clockwise (marked H+) adds damping, counter-clockwise (S-) takes it away. The manufacturer gives starting points: 0-10 compression and 0-12 rebound clicks for town use, 10-20 and 12-22 off-road, 15-24 and 22-36 for extreme driving. Treat them as a baseline - load and driving style will move them.

The reservoir mounts on the supplied bracket and clamps, somewhere protected from impacts. Our workshop can handle selection, fitting and the later rebuild.

Warranty and registration

The distributor states a 2-year or 100,000 km warranty which can be extended to 6 years in total. The condition: register the damper with the manufacturer after purchase (QR code in the instruction sheet), then carry out and report a service before 2 years / 100,000 km, and a second one before the next 2 years / 50,000 km. Each reported service adds another 2 years and 50,000 km of cover.

Why it is worth it

• 60 damping settings - one vehicle, several personalities.
• Oil cooling solved by hardware rather than by a marketing line.
• A serviceable design, so the cost of ownership spreads over years.
