Parts for your 2010 Holden Commodore-Bump stops

2010 Holden Commodore bump-stops: what they do and when to replace them

Yes, the 2010 Holden Commodore (VE series) is fitted with bump-stops front and rear. Technical sources including the Holden VE Service Manual (Chassis and Suspension), Gregory’s VE Commodore Service & Repair Manual (2006–2013), and parts catalogues from GM Holden and Monroe (Strut-Mate boot and bump-stop kits) all specify jounce bumpers/bump-stops as part of the MacPherson strut front and rear shock assemblies.

On a 2010 Commodore, the bump-stops act like soft, progressive cushions that prevent the suspension from crashing into its mechanical limits on big hits, full loads, or when towing. They protect struts, shocks, control arms and mounts from damage, help keep the tyre contact patch stable at max compression, and tame that harsh “bottom-out” thud. On the VE’s front MacPherson struts, the bump-stop sits under the dust boot on the strut rod, at the rear, the shock absorber carries its own bump-stop under the boot. Many quality boot kits bundle a new bump-stop because the foam or elastomer ages and cracks over time.

Servicing-wise, bump-stops deserve a look any time the car’s on a hoist, or whenever shocks/struts are being replaced. They don’t have a strict kilometre interval, but a quick inspection every 20,000–30,000 km is smart—especially if the car tows, carries loads, cops rough roads, or runs lowered springs. Lowered VE setups, in particular, rely more on the bump-stops to control travel, so using the correct height and rate is crucial to avoid harshness or unpredictable handling.

• Signs they’re due: cracked or crumbly foam, missing/detached bump-stops, torn dust boots, frequent bottoming-out, new clunks over speed humps, or uneven tyre wear that coincides with harsh impacts.
• Best practice: replace in axle pairs (both fronts or both rears), fit new dust boots at the same time, and check strut mounts/bearings. After front strut work, get a wheel alignment.
• Compatibility: stick with genuine GM Holden parts or reputable aftermarket kits specified for VE. If the car is lowered, choose bump-stops matched to the spring and damper travel.
• Safety tip: suspension work requires proper spring compression tools and torque specs from the manual. If unsure, leave it to a qualified tech.

Keeping the Commodore’s bump-stops healthy helps the shocks live longer, smooths out the sharp hits, and keeps the big Holden riding and handling the way it should on Aussie and Kiwi roads.

Popular questions about 2010 Holden Commodore bump-stops

Do VE Commodores have bump-stops on both axles?
They do. The front MacPherson struts use a jounce bumper under the dust boot, and the rear shocks have their own bump-stop. They’re part of the factory suspension design noted in the VE service literature and parts listings.

How often should bump-stops be replaced?
There’s no fixed schedule. Inspect them at each major service or whenever shocks/struts are changed. Replace if the foam is perished, split, missing, or if the car bottoms out. Heavy use or lowered setups may need earlier attention.

Can worn bump-stops damage other parts?
Yes. Without effective bump-stops, the suspension can hit its travel limit hard, stressing shocks, mounts and bushings, and contributing to harsh impacts that can upset tyre contact and wear.
