Parts for your 2015 Holden Colorado-Coil springs

2015 Holden Colorado Coil Springs

Per Holden/GM technical specifications and the RG-series workshop literature used by dealers and suspension manufacturers, the 2015 Holden Colorado runs an independent front suspension with coil-over shock assemblies and a live rear axle on leaf springs. So coil springs are absolutely relevant on the 2015 Colorado—at the front—while the rear uses leaf packs.

Up front, the coil springs carry the ute’s nose, set ride height, and help control body movement over corrugations, kerbs and tracks. Paired with the front dampers, they keep the tyres planted, steering sharp and braking consistent. Whether it’s a tradie’s tray or a weekend tow rig, healthy front coils matter for comfort, control and tyre life.

There’s no fixed replacement interval for front coils, they’re wear-and-tear items that should be inspected at service time. Look for chipped paint and rust, broken ends, sagging ride height, or coils that have shifted in their seats. Any Colorado running a bullbar, winch or dual battery can overload standard-rate coils, so heavier-rate options may be sensible to restore ride height and travel.

• Typical signs they’re tired or damaged: front end sitting low, clunks over bumps, uneven tyre wear, floaty steering, or the ute bottoming out.

When replacing, it’s smart to do coils in pairs and assess the struts/shocks at the same time—worn dampers will kill new springs quickly. Always refit new insulators/top mounts as needed, torque fasteners with the suspension at ride height, and book a wheel alignment straight after. Because coils store a lot of energy, safe removal needs a quality spring compressor and proper technique—most owners will be better off letting a pro handle it.

Chasing a lift or extra payload? Match spring rate to accessories and intended use, and pair lifted coils with compatible dampers to maintain travel and CV angles. Keep local rules in mind: modifications must comply with ADRs in Australia and may require LVV certification in NZ. A quick chat with a suspension specialist can save tyres, time and cash down the track.

As part of routine servicing, a visual check every 10–15,000 km for corrosion, cracked powdercoat, distorted seats and leaking struts keeps the Colorado’s front end tight and tidy.

Popular questions about 2015 Holden Colorado coil springs

Does the 2015 Colorado have coil springs front and rear?
It runs coil springs on the front independent suspension and leaf springs on the rear live axle across 4x2 and 4x4 variants. Rear coils weren’t fitted from factory.

Do I need a wheel alignment after replacing front coils?
Yes. Changing springs alters ride height and geometry. An alignment restores correct camber/caster/toe to protect tyres and keep the steering tracking straight.

When should front coils be upgraded?
If the ute has a bullbar, winch or spends life towing or on rough roads, heavier-rate coils help maintain ride height and control. If the nose sags, bottoms out, or the coating is cracked and rusty, it’s time.
