EFS MRP 2.5 assembled front strut, 50 mm lift — RAM 1500 DS Classic

On a 1500 DS the front axle carries everything: engine, accessories, often a bar and a winch. Once the standard strut loses control of that, the truck starts rocking over holes and floating when the surface turns rough.

This EFS MRP 2.5 strut arrives assembled — a monotube shock with a 700 lbs spring and a remote cooling canister. It lifts the front by 50 mm, is rated for an extra 50-110 kg, and the damping is set by dial: 24 compression clicks and up to 36 rebound settings.

Key benefits

• Factory-assembled McPherson strut — shock and spring arrive as one ready unit, no spring compressor work in your driveway.
• 24 compression settings — a dial on the reservoir changes the damping character without removing anything from the car.
• Up to 36 rebound settings — you decide how fast the wheel returns to the ground after a hit, which is how much grip you keep on gravel.
• Heavily finned remote canister — the oil runs cooler, and cooler oil holds consistent damping far longer on a long corrugated stage.
• Monotube layout allows a larger piston, which translates into extra control over suspension movement.
• Adjustable front ride height through spring preload — you set the car up for the load it actually carries.
• Zinc-plated seamless steel body and a solid aluminium top hat — built for salt, mud and years of service.
• Fully serviceable: it can be stripped, rebuilt and re-gassed instead of being thrown away.
• A 700 lbs spring matched to this strut by the manufacturer — you buy a complete, balanced assembly.
• Headroom for an extra 50-110 kg up front, roughly what a bar with a winch adds.

Vehicle fitment

• RAM 1500 DS "Classic" 3.0 diesel and 5.7 petrol from 01.2012 — 50 mm lift, additional load 50-110 kg

What you get

• Fitting instructions with a QR code for warranty registration

Technical data

Who it is for

For a RAM 1500 DS Classic that actually works: hauling, towing, unsealed roads and more than a factory bumper up front. The 50 mm of lift restores clearance, and the 700 lbs spring is matched to this exact strut, so there is no guesswork in the pairing.

The adjustment earns its place when the truck runs empty one day and loaded the next — the damping character changes by dial, with no trip to the hoist.

Fitting and notes

• The price covers one piece — a full front axle takes two of these.
• Register the shock with the manufacturer after purchase: scan the QR code from the instructions in the box and fill in the form. Without registration the extended warranty cannot be activated.
• The extension runs through servicing: the first service before 2 years and 100,000 km adds 2 years and 50,000 km, a second one before the next 2 years and 50,000 km takes the total up to 6 years.
• Set compression and rebound after fitting, to suit the load the vehicle actually carries — both dials stay accessible.
• Any change of front ride height is a good reason to check the alignment; our workshop can do it together with the fitting.

Why choose it

• The strut comes complete: shock, 700 lbs spring and reservoir as one matched assembly.
• 24/36-click adjustment and a finned remote canister are competition-grade hardware applied to a loaded daily 4x4.
• Full serviceability plus a warranty of 2 years or 100,000 km, extendable up to 6 years — this is a component bought for years, not for one season.
