Parts for your 2015 Mitsubishi Lancer-Bump stops

2015 Mitsubishi Lancer bump-stops

Bump-stops are absolutely fitted to the 2015 Mitsubishi Lancer. Mitsubishi’s factory Service Manual for the CJ/CF series (Front Suspension Group 33A and Rear Suspension Group 34) depicts jounce bumpers/bump-stops as part of the strut and shock assemblies. The Mitsubishi ASA electronic parts catalogue for 2015 Lancer likewise lists front and rear “stoppers” alongside the dust boot kits. Major aftermarket catalogues (KYB and Monroe) also supply boot-and-bump-stop kits specifically for 2008–2017 Lancer, further confirming their use on this model.

On a 2015 Lancer, the bump-stops act like soft, progressive cushions that prevent the suspension from bottoming out under heavy loads, big potholes or spirited driving. They’re usually microcellular foam pieces sitting on the strut rod up front and on the shock piston rod at the rear, often tucked inside the dust boots. When the suspension nears full compression, the bump-stop compresses smoothly, protecting the strut or shock internals, helping the car keep its composure, and reducing nasty knocks that travel through to the cabin.

For servicing, they’re small parts that make a big difference. If they’ve perished, cracked or collapsed, you’ll feel harsher impacts, hear a dull thud on big compressions, and potentially stress the dampers and mounts. It’s smart to check them any time the wheels are off—say at tyre rotations, brake work, or during a WOF/roadworthy check. Many workshops in Aus and NZ treat bump-stops as “replace with” items whenever fitting new shocks/struts because the front MacPherson setup has to be disassembled anyway. That saves labour later and keeps the dust boots fresh too.

Typical inspection pointers:

• Look for crumbling foam, splits, or a dust boot that’s torn or missing.
• Note any bottoming-out feel over speed humps or with a loaded boot—often a sign the stopper’s had it (or the damper is weak).
• If the car’s lowered, ensure shortened or compatible bump-stops are used so there’s proper travel.

Replacement is straightforward at the rear and more involved up front because the front struts need spring compression. Always follow the factory torque specs and orientation in the Mitsubishi manual. Fresh bump-stops help preserve ride quality, protect expensive dampers, and keep the Lancer feeling tight and tidy over Aussie and Kiwi roads.

Popular questions about 2015 Mitsubishi Lancer bump-stops

Do all 2015 Lancer variants have bump-stops?
Yes. Whether it’s an everyday commuter trim or a sportier variant, the front MacPherson struts and the rear shocks use bump-stops. Designs can vary slightly by suspension type and market spec, but they’re present on every model year 2015 Lancer.

How often should bump-stops be replaced?
There’s no strict kilometre interval. Inspect them during routine services. Replace them when they show cracking or collapse, the dust boots are torn, or whenever you’re fitting new shocks/struts. Many techs replace them proactively around the time dampers are renewed.

Can bump-stops be changed without replacing shocks?
Yes. Rear ones are usually simple. Front ones can be replaced on their own, but the strut must be removed and the spring compressed, so most owners pair the job with new struts or mounts to maximise value on labour.
