Parts for your 2022 Subaru Impreza-Bump stops

2022 Subaru Impreza bump-stops: what they do and when to replace them

Short answer: yes, the 2022 Subaru Impreza is fitted with bump-stops (also called jounce bumpers). Technical documentation backs this up. The Subaru Impreza (GK/GU, MY2017–2023) Service Manual – Suspension lists “Bumper” components on both the MacPherson front struts and the rear shock absorbers. Subaru’s genuine parts catalogues for these model years also show the front strut bumper and rear shock bumper as separate service parts, often supplied with or alongside the dust boot. Major damper suppliers’ catalogues for the Impreza (e.g., KYB, Monroe) likewise list compatible bump stops/jounce bumpers for the platform. So bump-stops are relevant and fitted to the 2022 Impreza.

On this model, bump-stops act as a secondary spring right at the end of the suspension’s travel. When a big pothole, speed hump or a fully loaded boot pushes the suspension close to bottoming out, the bump-stop progressively cushions the last bit of movement. That protects the strut/shock internals, keeps the tyres in better contact with the road, and stops nasty metal-on-metal knocks. They also help tuning body control, so the car feels calmer mid-corner over sharp bumps—handy on Aussie and Kiwi backroads.

They’re made from microcellular foam or rubber and live under the dust boot on the front struts and on the rear shocks. Over time they can harden, crack, or get chewed up—especially if the dust boot tears and lets in grit, or if a leaking damper soaks them in oil. Typical signs they’re done include harsh bottoming, thuds over big hits, or visible crumbling during an inspection.

• Inspection timing: check bump-stops whenever struts/shocks are inspected or replaced, and at roughly 40,000–60,000 km intervals if driving on rough roads.
• Best practice: replace them any time you fit new struts/shocks, or if the dust boots are torn. Do them in axle pairs.
• Parts choice: genuine Subaru or reputable aftermarket that matches OE length and rate. Many come as a boot-and-bump-stop kit.
• Fitment notes: support the hub properly, torque fasteners to spec, and book a wheel alignment if a strut is removed. Avoid jacking methods that crush the bump-stops.

Staying on top of bump-stops keeps the Impreza riding quietly, protects pricey dampers, and helps it track true when the road gets ordinary.

Popular questions about 2022 Subaru Impreza bump-stops

Does the 2022 Impreza actually have bump-stops, or are they built into the shocks?
It has dedicated bump-stops. They’re separate service parts and sit beneath the dust boots on the front struts and on the rear shocks. Some replacement kits bundle the boot and bump-stop together, which can make it look “built-in”.

When should bump-stops be replaced on a 2022 Impreza?
Replace them when they’re cracked, oil-soaked, or misshapen, or automatically when fitting new struts/shocks. If you hear bottoming thuds over big hits, add them to the shortlist. Regular inspection during scheduled servicing is smart, especially after 40,000–60,000 km on coarse-chip or gravel roads.

Will changing bump-stops affect ride height or WOF/roadworthy?
They don’t alter static ride height, but healthy bump-stops improve end-of-travel control. Damaged or missing bump-stops can contribute to suspension defects that may attract attention at WOF/roadworthy. Fitting correct-spec parts helps keep everything above board.
