NM654M1 Shock Absorber Nitro.
Category: Suspension and 4x4 parts


The RAW 4x4 NM654M1 is a Nitro-series shock absorber for the Nissan Navara D40 dual-cab ute, covering all ABS-equipped variants except the STX550. It's a damper-only replacement aimed at restoring control to a D40 whose original shocks have worn out.
Where a spring carries the load, the NM654M1 controls the movement around it — slowing rebound after a hit and keeping the tyre on the road so the Navara doesn't wallow or bounce. It's the part to fit when a D40 feels floaty over corrugations or no longer settles after a speed hump. As a Nitro-series shock it's a straight replacement for the worn factory unit, working with whatever spring the ute already runs rather than altering ride height.
It's listed to fit the Nissan Navara D40 dual-cab ute, all variants with ABS, with the STX550 specifically excluded — that model runs its own damper. The supplier doesn't publish the year span or whether this is the front or rear unit, so confirm your variant and the position you need with the workshop before ordering.
A worn shock fades gradually, so the opposite side is usually tired too. Oak Flats Muffler Men fits Nitro dampers like the NM654M1 across the Illawarra and replaces them in axle pairs so the D40 sits and reacts evenly; we inspect the bushes and mounts at the same time, and verify the truck isn't an STX550.
RAW 4x4 hasn't published a fixed price for the NM654M1, so we treat it as a quote-on-order item: tell us your D40 variant and which corner you need and we'll confirm availability and cost before the part comes in. That keeps you from ordering the wrong damper for an STX550-excluded listing.
