Parts for your 2014 Mitsubishi Asx-Bump stops

2014 Mitsubishi ASX bump-stops — fitted and worth looking after

Technical sources confirm the 2014 Mitsubishi ASX is fitted with bump-stops front and rear. The Mitsubishi Motors Service Manual for RVR/ASX/Outlander Sport (GA-platform, 2010–2015) lists a “bump stopper/jounce bumper” within the front MacPherson strut assembly and a rear suspension “spring bumper.” Genuine parts catalogues (Mitsubishi ASA/EPC) show dedicated part numbers for these components, and major suspension suppliers’ protection kits for ASX models include the foam jounce bumper with the dust boot. So, yes—bump-stops are relevant and used on the 2014 ASX.

On a 2014 ASX, bump-stops act like soft limiters for suspension travel. They’re usually microcellular polyurethane foam that compresses progressively on big hits, stopping the strut or shock from bottoming out. That protects the damper internals, keeps the tyre off the inner guard, and helps the car hold its line when it cops a heavy load or a nasty pothole. In day-to-day driving around Aussie and Kiwi roads, that translates to less clunking, better ride quality, and more predictable handling when the suspension is near full compression.

Because bump-stops quietly do their job out of sight, they’re easy to forget—until they crumble, crack or go missing. Heat, age, oil contamination and rough tracks can degrade them. When they’re perished, the ASX can feel harsh on big bumps, make a hollow thud over speed humps, or show scalloping on tyres from repeated hard bottom-outs.

As part of routine servicing, it’s smart to inspect the front strut protection kits and rear bumpers every 20,000–30,000 km, or any time shocks/struts are replaced. If the dust boot is torn, there’s a good chance the jounce bumper is on the way out too. Replacing in axle pairs keeps the car balanced. Fit quality OEM-equivalent parts, seat them correctly on the piston rod or body, and check related hardware like top mounts and spring insulators. After front strut work, a wheel alignment is recommended to keep tyre wear tidy.

For ASX owners who tow, carry gear, or venture onto corrugations, healthy bump-stops are cheap insurance. They help the suspension survive big compressions and keep the ride composed—exactly what’s wanted on long kilometres across Aussie highways or winding Kiwi backroads.

• Watch for: cracking or missing foam, oil-soaked bumpers, harsh thuds on compression, and uneven tyre wear.
• Good practice: replace with the struts/shocks, renew dust boots, and verify torque settings with the service manual.

Popular questions about 2014 Mitsubishi ASX bump-stops

Do the front and rear of a 2014 ASX both have bump-stops?
Yes. The front MacPherson struts use a foam jounce bumper under the dust boot, and the rear suspension uses dedicated spring bumpers. Both are there to control end-of-travel and protect the dampers from hard bottom-outs.

How often should ASX bump-stops be replaced?
They don’t have a strict interval, but they should be inspected at each major service and replaced whenever the struts or shocks are changed, or if there’s visible cracking, collapse, or oil contamination. Many owners renew them around the same time as dampers, typically between 80,000–150,000 km depending on use.

Can worn bump-stops cause a WOF/roadworthy issue?
Potentially. If a bump-stop is missing or severely deteriorated, the suspension can bottom out, which may be flagged during a WOF/roadworthy for safety reasons. Replacing them restores proper suspension travel control and helps pass inspection.
