Sized for the GSJ15/GSJ15R FJ Cruiser, the RAW 4x4 NM540 is a Nitro-series shock absorber — a single nitrogen-charged damper for one corner of Toyota's 4.0L V6 wagon.

Will the NM540 suit my FJ Cruiser?

It's listed to fit the Toyota FJ Cruiser GSJ15 and GSJ15R wagon with the 4.0L V6. The FJ Cruiser is a coil-sprung wagon, so the damper works alongside the coils to control body movement rather than setting ride height. RAW 4x4 sells the Nitro range per unit and per position, so the NM540 covers a specific corner — tell us whether you want a single shock or a set and we'll confirm the part and quantity.

What the Nitro name covers

Nitro refers to the nitrogen gas charge inside the damper body, a design intended to resist the fade a plain hydraulic shock develops under sustained corrugations or load. It's a construction descriptor, not a tested figure — our record holds no bore, stroke, valving or sound data for the NM540, so we don't publish any.

Is a new shock a compliance concern?

Shocks are suspension parts, not exhaust or emissions hardware, so the exhaust road-legality rules don't apply to a straight replacement. Renewing tired dampers is normal maintenance; if the shock is going in as part of a lift, broader NSW modification rules can come into play and we'll walk you through them.

Fitting at our Illawarra workshop

Oak Flats Muffler Men supplies and fits Nitro dampers in-house across the Illawarra. We support the suspension, remove the old shock, fit the new unit with fresh bushes where needed and torque the mounts. Because feed data can be imperfect, we confirm the NM540 matches your FJ Cruiser before it goes on.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.

Common questions

Is the NM540 sold individually?
Yes — RAW 4x4's Nitro shocks are listed per unit. How many you need depends on the corners you're replacing, which we'll confirm with you before ordering.
Are any power or sound figures available?
No. This is a suspension damper and our record carries no dyno, valving or sound data. We describe it only as a nitrogen gas-charged Nitro shock for the FJ Cruiser.
