Parts for your 2009 Holden Colorado-Struts

2009 Holden Colorado struts — what’s actually fitted and what to service instead

For the 2009 Holden Colorado (RC series), front struts aren’t used. This ute runs an independent double wishbone front suspension with torsion bars (most 4x4 and High-Ride variants) or coils (some 4x2 trims), and a live rear axle on leaf springs. In every case, it uses separate telescopic shock absorbers rather than MacPherson-style strut assemblies. That makes “struts” not relevant for this model year and platform.

Technical sources that document this layout include factory workshop manuals for the Holden Colorado RC and its Isuzu D‑MAX TFR/TFS twin, which specify double wishbone front suspension with torsion bar or coil spring and separate shock absorbers, plus a leaf-sprung rear axle with separate shocks. Aftermarket catalogues for this generation (e.g., Monroe and KYB) list front and rear shock absorbers by part number and do not list strut assemblies. Period specification sheets for the RC Colorado likewise state double wishbone front suspension and leaf rear, with no reference to strut towers.

Why no struts? On ladder-frame utes like the 2009 Colorado, wishbones with torsion bars or coils and separate shocks offer ruggedness, payload headroom, and easier ride-height tuning for accessories, towing, or off-road work. A strut would need a reinforced upper tower in the body shell, the Colorado’s chassis design suits control arms and separate dampers instead, keeping components tough and serviceable for harsh Aussie and Kiwi conditions.

What should owners service instead of “struts”? Focus on the shock absorbers and the surrounding hardware: upper and lower control arm bushes, ball joints, torsion bar mounts, sway bar links and bushes, and rear leaf spring bushes and U-bolts. A wheel alignment after front-end work is a must. Quality shocks typically last 80,000–120,000 km, but heavy corrugations, towing, or big loads can shorten that. Look for oil misting on the shock body, longer stopping distances from nose-dive, extra bounce after bumps, steering shimmy, or choppy tyre wear.

• Key checks: shock leaks or dents, uneven tyre wear, perished bushes, excessive bounce, clunks over corrugations.
• When replacing shocks: choose valving to match use (touring, towing, off-road), replace in axle pairs, and re-torque mounts after a short shakedown.

Note: Some 4x2 RC trims use coils up front, but they’re still not MacPherson struts. They remain wishbone-based with separate shocks.

Popular questions about 2009 Holden Colorado “struts”

Does a 2009 Holden Colorado have front struts?
No. It uses a double wishbone front end with torsion bars or coils and separate shock absorbers. There are no MacPherson strut assemblies on this model.

What should be replaced when doing the front shocks?
Alongside the shocks, it’s smart to inspect and, if needed, replace upper and lower control arm bushes, ball joints, sway bar links and bushes, and torsion bar bushes. Finish with a wheel alignment to protect tyres and steering feel.

How often should the shocks be changed on a Colorado?
Many owners see 80,000–120,000 km from quality shocks, but rough roads, towing, and accessories can shorten that. If there’s oil misting, extra bounce, brake dive, or cupped tyres, it’s time to test and likely replace them.
