Parts for your 2017 Holden Colorado-Coil springs

2017 Holden Colorado coil-springs — what they do and when to replace them

Based on technical sources — including the Holden RG Colorado Owner’s Manual (2017), GM Holden media specifications for the 2016–2017 update, and workshop references such as Gregory’s/Max Ellery manuals covering Colorado/D-Max (2012–2019) — the 2017 Holden Colorado ute runs coil springs on the front suspension (independent double wishbone with coil-over struts and a stabiliser bar) and leaf springs on the rear live axle for load carrying. So coil-springs are absolutely relevant on this model, just at the front end. The Colorado 7/Trailblazer SUV variant uses rear coils, but the ute retains rear leaf packs to support payload.

Up front, the coil springs support vehicle weight, hold the ride height, and let the shocks do their job keeping the tyres planted. They work hard on Aussie and Kiwi roads — corrugations, worksites, towing and beach runs — so staying on top of their condition keeps steering feel sharp and braking stable.

There’s no fixed replacement interval for front coils, but they should be inspected at each service or at least every 20,000–30,000 km. Look for chipped coating, rust, broken pigtails, uneven ride height, or a nose‑down stance. If fitting a bull bar, winch, dual batteries or a canopy that shifts front axle load, consider springs with the correct rate to suit the added weight — keeping things legal and within GVM.

• Common signs they’re tired: clunks over bumps, bottoming out, increased body roll, wandering or tramlining, and scalloped front tyre wear.
• Best practice when replacing: do both front springs as a pair, use quality springs matched to Colorado’s RG chassis, and renew strut mounts/insulators if worn.
• Always follow torque specs and orientation from the service manual and finish with a wheel alignment.

Avoid quick fixes like cutting or heating springs — they weaken the steel and can fail. If chasing a lift, use properly engineered coil/strut kits rated for the vehicle, keep CV and caster angles sensible, and check local rules (e.g., NZ WoF/VIRM, Australian state regs) for certification thresholds. With the right coils under the nose, the 2017 Colorado tracks straighter, brakes truer and soaks up the rough stuff without drama.

• Are front coil springs the same across all 2017 Colorado trims?
  Most 4x2 and 4x4 ute trims share the coil-over front layout, but spring rates can vary with engine, cab style and accessories. When replacing, match the spring rate to the vehicle’s build and any added front-end weight.
• Can worn front coils cause uneven tyre wear?
  Yes. Sagging or broken coils alter ride height and wheel alignment angles, which can chew out tyres and affect braking stability. After any spring work, get a proper alignment.
• What’s a sensible lift for a daily-driven 2017 Colorado?
  About 40–50 mm using rated coils and matched dampers keeps geometry and CV angles happy for most on-road and mild off-road use. Check local regulations for certification and keep within GVM and ESC requirements.
