Parts for your 2013 Mitsubishi Lancer-Bump stops

2013 Mitsubishi Lancer bump-stops — what they do and when to replace them

Yes, the 2013 Mitsubishi Lancer uses bump-stops. Technical sources that confirm this include the Mitsubishi Lancer CJ platform Workshop Manual (Front Suspension Group 33A and Rear Suspension), which specifies “bound bumpers” on the strut/shock assemblies, the Mitsubishi ASA/ CAPS parts catalogue that lists front strut and rear shock bumpers as service parts, and major shock catalogues (e.g., KYB and Monroe) that supply strut-boot kits with integral jounce bumpers for the 2013 Lancer. So, bump-stops are absolutely relevant to this model.

On the Lancer, bump-stops act like compact safety cushions. They’re mounted on the front MacPherson struts and rear shocks, engaging only on big hits or heavy loads. Their job is to prevent metal-to-metal bottoming, protect the dampers and towers, and add a progressive “last line of spring” so the ride stays controlled when the suspension runs out of travel. They also help keep tyre contact more consistent and cut down on clunks and harshness over Aussie and Kiwi backroads.

For servicing, they’re a “check when you’re in there” item. Whenever shocks/struts are replaced, the bump-stops and dust boots should be inspected. If they’re cracked, crumbling, oil-soaked from a leaking damper, or missing pieces, replace them. Most owners will see them wear out around the same time as struts—often between 80,000 and 150,000 km depending on use and road conditions. If the car’s been lowered or regularly carries loads, consider heavy-duty or shorter bump-stops designed for the setup.

• Typical symptoms they’re shot: a hard thud on big bumps, sudden bottoming-out, split boots, or visible perishing of the foam/urethane bumper.
• Best practice: replace in axle pairs, use quality OE or reputable aftermarket kits, and torque everything to spec. An alignment is wise after front strut removal.
• DIY note: front strut bump-stops sit under the top mount—spring compressors and care are required. If unsure, let a pro handle it.

Sorting tired bump-stops won’t magically cure every knock, but it protects new shocks, smooths out sharp hits, and helps the Lancer feel tight and composed over rough surfaces—exactly what’s wanted for daily commuting or weekend missions.

Do all 2013 Lancer variants have bump-stops?

Yes. Whether it’s an ES, VR, VRX, GSR, Ralliart, or other CJ-series variant, the platform uses bump-stops on the front struts and rear shocks. Performance models may have different rates or part numbers, but the function is the same—protect travel and keep things controlled on big compressions.

How often should bump-stops be replaced?

There’s no strict interval, but a sensible approach is to inspect them whenever shocks or struts are replaced—commonly around 80,000–150,000 km. Replace them if they’re perished, cracked, or oil-soaked. If the car’s lowered or sees rough roads, check more frequently.

Will new bump-stops fix a knocking noise?

They can help if the noise comes from bottoming-out or a destroyed bumper. But many knocks come from top mounts, sway bar links, or worn bushings. A proper suspension inspection will pinpoint the culprit so you’re not guessing.
