Parts for your 2012 Holden Colorado-Coil springs

2012 Holden Colorado Coil Springs

Based on the Holden RG Colorado Service Manual (2012–2016), Holden Australia’s 2012 Colorado media information, and common spec listings used by local workshops, the 2012 Holden Colorado ute runs coil springs on the front (independent double-wishbone with coil-over struts) and leaf springs on the rear for load carrying. The Colorado 7 SUV variant (also launched in 2012) uses rear coil springs on a five‑link live axle. So coil springs are absolutely relevant to the 2012 Colorado’s front suspension, and to the Colorado 7 at the rear.

Up front, the coil springs support vehicle weight, set ride height, and work with the shocks and control arms to keep tyres planted and steering feel consistent. They’re tuned for a balance of comfort on bitumen and control on corrugations or work sites. Add-ons like a bullbar, winch, or dual batteries can nudge the nose down, that’s when heavier-rate front coils may be worth a look to restore ride height and handling.

Coil springs don’t have a fixed replacement interval, but they should be inspected at each service (or about every 20,000 km). Tell-tale signs they need attention include:

• Nose-down stance or uneven ride height side-to-side
• Clunks, creaks, or a harsh, crashy ride over bumps
• Uneven tyre wear or vague steering on turn-in
• Cracked paint, rust pitting, or a broken coil “pigtail”

When replacing, best practice is to do both front coils as a pair and match them to suitable shocks. After any spring work, a wheel alignment is a must. Inspect and, if needed, replace related bits like strut top mounts/bearings, spring isolators, and bump stops. Springs should be compressed with the proper tooling, and all control-arm and strut fasteners torqued at normal ride height to avoid bush bind.

If chasing a small lift or heavier rate coils for accessories, keep changes sensible to protect CV and ball-joint angles. Stay within legal and certification requirements (ADR/VSB guidelines in Australia, LVVTA rules in NZ) and ensure the setup maintains safe handling and braking. Note that the ute’s rear is leaf-sprung from factory, rear coil conversions are a specialised job, whereas the Colorado 7 already has rear coils and different spring specs.

Popular questions about 2012 Holden Colorado coil springs

Does a 2012 Holden Colorado have rear coil springs?
The ute uses rear leaf springs for load capacity, with coil springs on the front only. If it’s the Colorado 7 SUV, that model uses rear coil springs on a five-link axle. Always check the exact variant before ordering parts.

How often should front coil springs be replaced?
There’s no set kilometre interval. Inspect every service for sagging, damage, and corrosion. Many last well past 150,000 km, but replace immediately if the ride height drops, a coil breaks, or handling turns sloppy. Always replace coils in pairs and get an alignment.

Can heavier-rate or lifted coils be fitted to a 2012 Colorado?
Yes—common when adding a bullbar or winch, or for light touring. Match coils to appropriate shocks, keep lift modest, and ensure legal compliance. After fitment, check alignment, headlight aim, and that steering and ABS/ESC behaviour remain predictable.
