Parts for your 2020 Holden Colorado-Strut mounts

2020 Holden Colorado strut-mounts — are they used on this ute?

Short answer: no, the 2020 Holden Colorado doesn’t use MacPherson struts, so “strut-mounts” in the classic sense aren’t fitted. The factory front end is an independent double-wishbone setup with a coil-over shock absorber, and the rear runs a live axle with leaf springs and separate shocks. That architecture means there’s no strut tower carrying steering and suspension loads, so there’s no strut mount to replace like you’d see on a small car with a MacPherson front end.

Technical sources that describe this layout include Holden/GM service information for the RG Colorado (2016–2020) under Front Suspension – Description and Operation, as well as OEM parts cataloguing that lists front shock absorber upper mounts/insulators rather than strut top mounts. Those references make it clear the hub is located by upper and lower control arms, with steering loads managed through ball joints and the knuckle, not through a strut.

Why that matters: a strut mount is a structural and rotating top mount for a MacPherson strut. The Colorado’s coil-over shock doesn’t locate the hub and doesn’t rotate for steering, so the top mount is simply a shock absorber mount/insulator. Different job, different wear pattern, different service approach.

What owners should look after instead:

• Front shock absorber upper mounts/insulators and top plates – can squeak or clunk when perished, especially on corrugations or after a lift.
• Upper and lower control arm bushes and ball joints – key to alignment stability and tyre wear.
• Stabiliser (sway) bar links and bushes – common sources of front-end knocks.

Service tips: inspect the front shocks, upper mounts and control arm bushes at regular services (every 20,000 km is a good cadence for mixed on/off-road use). Replace shocks and upper mounts in axle pairs for even handling. A wheel alignment is recommended after any front-end work, and is essential if control arms are removed, camber bolts are touched, ride height is changed, or bushes/ball joints are replaced.

If an online catalogue calls a Colorado part a “strut mount”, it’s usually referring to the shock’s top mount or insulator kit. It’s compatible language-wise, but it isn’t a MacPherson strut mount.

Does a 2020 Holden Colorado have strut mounts?
The Colorado uses a double-wishbone front suspension with a coil-over shock, not a MacPherson strut. That means there’s no traditional strut mount. The top component is a shock mount/insulator, which doesn’t carry steering loads.

What should be serviced instead of strut mounts on a Colorado?
Focus on front shock absorber upper mounts/insulators, the shocks themselves, upper and lower control arm bushes and ball joints, and sway bar links/bushes. These items influence noise, ride quality and alignment.

Do you need a wheel alignment after replacing front shocks or top mounts?
It’s best practice to get an alignment. If you’ve changed ride height, removed control arms, or adjusted camber bolts, an alignment is essential to prevent uneven tyre wear and poor steering feel.
