Infiniti M56 Bare Strut Sets

Infiniti M56 Bare strut sets

Bare strut sets for your Infiniti M56 start at $101.95, with 3 options in stock from FCS. A bare strut is the structural shock-absorbing tube without a spring or mount — the core component that controls wheel movement and keeps tires planted. When struts wear out, handling degrades and tire wear accelerates, making timely replacement important for safety.

Signs your Infiniti M56 needs new bare struts

  • Nose dives sharply under braking or squats heavily during acceleration
  • Steering feels vague or floaty, especially through curves and lane changes
  • Uneven or cupped tire wear patterns visible across the tread surface
  • Bouncing continues for two or more cycles after hitting a bump or dip
  • Clunking or knocking sounds from the front or rear suspension over rough pavement
  • Visible oil streaking or wet residue on the outside of the strut body

Which bare strut set should you buy for your Infiniti M56?

Because a bare strut set ships without a spring, mount, or bump stop, you are either reusing your existing hardware or sourcing those pieces separately — so fit and valving are the two decisions that matter most. Consider how and where you drive your Infiniti M56: daily commuting, light hauling, or spirited driving each call for a different valving tune. Confirm whether you need front, rear, or a complete four-corner set before ordering.

Replacing bare struts on a Infiniti M56

Replacing a bare strut on your Infiniti M56 involves safely compressing the coil spring, separating the old strut from the knuckle and upper mount, then assembling the spring and hardware onto the new bare strut before reinstallation. All fasteners should be torqued to the manufacturer's specification for your specific Infiniti M56, and the spring must be fully seated in its perch before any load is applied. Schedule a professional wheel alignment immediately after the job to restore proper suspension geometry.

Frequently asked questions

How much does it cost to replace bare struts on a Infiniti M56?
Parts alone start at $101.95 for a bare strut set for your Infiniti M56. Because a bare strut requires transferring or purchasing the spring, mount, and bump stop separately, total part costs vary widely. Professional labor typically adds one to three hours per axle, depending on spring compressor access and strut design.
What is the difference between a bare strut and a complete strut assembly for a Infiniti M56?
A bare strut is only the damper cartridge and housing — no spring, no upper mount, and no boot. A complete strut assembly includes all those components pre-assembled. Bare struts cost less upfront but require a spring compressor and additional parts, making them better suited for experienced DIYers or shops reusing serviceable hardware.
Can I replace just one bare strut on my Infiniti M56, or do I need a pair?
Replacing struts in pairs — both fronts or both rears together — is strongly recommended. Installing one new strut alongside a worn one creates uneven damping side to side, which causes pulling, uneven braking response, and inconsistent handling. Paired replacement ensures balanced performance and maximizes the lifespan of both new units.
Do I need a spring compressor to install bare struts on a Infiniti M56?
Yes. Because a bare strut ships without a spring, you must safely compress and transfer the existing coil spring — or install a new one — onto the new strut body. A spring compressor is required for this step. Improperly compressed springs store enormous energy and can cause serious injury; renting a proper tool or using a shop is advisable.
How long do bare struts last on a Infiniti M56?
Strut lifespan depends heavily on road conditions and driving habits, but most quality units remain effective for a broad range of miles or years before damping performance degrades noticeably. Vehicles driven frequently on rough or unpaved roads, or used for towing, will wear struts faster than those driven on smooth highways under normal loads.
Does replacing bare struts on a Infiniti M56 require a wheel alignment afterward?
Yes, a four-wheel alignment is recommended after strut replacement on your Infiniti M56. Struts are a structural part of the front — and sometimes rear — suspension geometry. Removing and reinstalling a strut can shift camber and caster settings enough to cause premature tire wear and pulling, even if the new strut appears to seat identically to the old one.
