Parts for your 2015 Mitsubishi Asx-Bump stops

2015 Mitsubishi ASX bump-stops

Checked against technical sources, bump stops are definitely fitted to the 2015 Mitsubishi ASX. The Mitsubishi Motors Service Manual for RVR/ASX/Outlander Sport (2010–2016) lists a “Bump Stopper (Jounce Bumper)” within the front strut assembly (Group 33 Front Suspension) and a rear shock/suspension “Bump Stopper” in the rear suspension section. The Mitsubishi ASA Electronic Parts Catalogue also shows front and rear bump stoppers for 2015 GA-series ASX variants, and major shock brands’ catalogues include strut boot kits with jounce bumpers specifically for ASX of this generation.

On the 2015 ASX, bump stops (often called jounce bumpers) are small but mighty bits of foam or polyurethane that sit inside the front struts and on the rear shocks. Their job is to gently catch the suspension at the end of its travel so metal doesn’t smash into metal. That protects the struts and shocks, keeps tyres from kissing the guards, and smooths out those big hits from potholes, corrugations, and speed humps.

They’re also part of the ride-and-handling recipe. As the suspension compresses hard, the bump stops progressively add spring rate, helping the ASX stay composed when loaded up, towing a small trailer, or tackling rough country roads.

• Protects shocks/struts and mounts from bottoming out
• Reduces harsh impacts and clunks over big bumps
• Helps maintain tyre clearance and alignment under load

Service-wise, they don’t have a strict replacement interval, but they should get a proper look whenever shocks/struts are inspected or replaced—typically every 40,000–60,000 km, and sooner if the vehicle sees rough roads. Tell-tales they’re due include cracking, crumbling, oil-soaking from a leaking shock, or a missing/torn dust boot. If the boot’s split, grit will chew out the bump stop and the shock rod faster than you’d like.

Front bump stops are part of the strut assembly, so the strut has to come out and the spring compressed to swap them—best done with the right gear. Rears are usually simpler but still worth doing in pairs for even feel. Choose quality OEM-equivalent parts, replace the dust boots at the same time, and have a wheel alignment after any front strut work. If the ASX carries loads, runs roof gear, or regularly sees corrugations, consider moving inspections forward—it’s cheap insurance against bigger suspension bills down the track.

Does the 2015 ASX have bump stops front and rear?

Yes. The front jounce bumpers live on the strut rods under the dust boots, and the rear bump stops are paired with the shock absorbers. Mitsubishi service literature and the parts catalogue list both.

How often should bump stops be replaced on a 2015 ASX?

There’s no fixed schedule. Inspect at major services or around 40,000–60,000 km, and replace if they’re cracked, perished, oil-soaked, or missing. Always replace in pairs and align the front end after strut work.

Can worn bump stops cause a WOF/roadworthy fail?

They can if they’re missing or allow metal-to-metal contact from bottoming out. Even if they just look tired, it’s smart to replace them before they lead to shock damage or unsafe handling.
