Parts for your 2012 Mitsubishi Outlander-Bump stops

2012 Mitsubishi Outlander bump stops — what they do and when to replace them

Yes, the 2012 Mitsubishi Outlander is fitted with bump stops (also called jounce bumpers) front and rear. This is confirmed by Mitsubishi’s factory documentation for the CW-series (2007–2013) Outlander: the Workshop/Service Manual sections for Front Suspension (MacPherson strut) and Rear Suspension identify the bump stopper on the strut/shock assembly, and the Mitsubishi ASA electronic parts catalogue lists dedicated front and rear “stopper” components in Group 33 (Suspension). Major aftermarket catalogues for Australia and New Zealand also supply boot-and-bump-stop kits for the 2012 Outlander, further verifying their fitment.

On a 2012 Outlander, bump stops act as a secondary, progressive spring right at the end of suspension travel. When the suspension compresses hard — say, over a deep pothole, heavy load, or a fast corrugation — the bump stop cushions the last bit of movement. That protects the shock absorber, control arms, strut mounts and body from a harsh metal-to-metal bottom-out. It also helps keep the tyre in contact with the road longer, which smooths the hit and improves stability. Because they’re made from microcellular polyurethane or rubber, they can age, crack, or crumble over time, especially if soaked in oil or exposed to UV and dust.

There isn’t a strict replacement interval, but a good rule is to inspect bump stops whenever shocks/struts or dust boots are serviced, and at least every 40,000–60,000 kilometres. Many workshops replace them proactively when fitting new struts, as access is straightforward with the assembly out. Signs they’re due include:

• A sharp thud or harshness on big bumps
• Visible cracking, missing chunks, or they’ve gone mushy
• Torn or missing dust boots (often the bump stop shares this kit)
• Evidence of oil contamination from a leaking shock

Service tips for a 2012 Outlander bump-stop job:

• Replace in axle pairs to keep ride and handling balanced
• Use quality OE-spec components for the correct progressive rate
• Torque fasteners at normal ride height to avoid bush preload
• If struts are disassembled, book a wheel alignment afterwards
• If the vehicle is lifted or lowered, choose stops matched to the new travel to stay legal and avoid premature bottoming

Popular questions

Do all 2012 Outlanders have front and rear bump stops?
Yes. Both the front MacPherson struts and the rear shock/suspension assemblies include bump stoppers, as shown in the Mitsubishi CW-series service manual and the Mitsubishi ASA parts catalogue. They’re standard fitment to prevent bottoming and protect the suspension.

How often should bump stops be replaced on a 2012 Outlander?
There’s no fixed interval. Have them inspected at regular servicing and any time shocks or struts are replaced. Many owners refresh them around the 80,000–120,000 km mark or sooner if they’re cracked, oil-soaked, or the ride gets noticeably harsh on big hits.

Are aftermarket polyurethane bump stops OK for this model?
They can be, provided the part is designed for the 2012 Outlander and maintains a progressive rate similar to OE. Overly hard universal stops can cause a choppy ride and extra stress on mounts. Stick with reputable brands and ensure modifications remain compliant with local regulations.
