Parts for your 2020 Honda Civic-Bump stops

2020 Honda Civic bump stops — what they do and when to replace them

Yes, the 2020 Honda Civic uses bump stops (also called jounce bumpers) at both ends. They’re a standard part of the suspension: in the front MacPherson struts they sit on the damper rod under the dust boot, and on the rear multi‑link they’re on the shock shaft. This is documented in the Honda Civic (2016–2021) Service Manual under front/rear shock absorber disassembly, and in Honda’s Electronic Parts Catalogue, which lists the bump stop (rubber stopper/jounce bumper) as a serviceable component for 2020 models.

On the road, these compact foam pieces act like a progressive secondary spring. They prevent metal‑to‑metal bottoming, help the Civic keep its geometry tidy under big compressions, protect the dampers, and smooth out the nastiest hits. Made from microcellular polyurethane, they compress predictably and work with the Civic’s spring and damper tuning to keep the tyres planted and the cabin calm. On lowered cars, they come into play more often, so the correct length and density matters a lot for ride and grip.

They don’t need constant attention, but they do age. Oil from a weeping shock, heat, and road grime can make them crumble or bind. Signs they’re past their best include a dull thud over speed humps, the suspension “crashing” on full load, squeaks as the dust boot rubs, or scalloped tyre wear after repeated bottoming. If the Civic is carrying people and gear regularly, tired bump stops can really show up in ride quality.

As part of routine servicing, a quick look every 20,000–30,000 km is a smart move, or any time shocks, springs or dust boots are off. Replace them whenever shocks are replaced, or if the foam shows cracking, chunks missing, or a permanent squashed shape. Stick with genuine Honda or quality aftermarket bump stops matched to the Civic’s damper travel—don’t delete them. If the car is lowered, trimming or changing bump stops should be based on measured suspension travel, not guesswork. After any suspension work, book a wheel alignment to keep tyre wear and handling on the money.

• Check under the dust boot for splits, crumbling, or missing pieces.
• Look for oil on the bump stop—often a clue the shock is leaking.
• Replace dust boots with the bump stops to keep grit out of the damper.

Popular questions about 2020 Honda Civic bump stops

Where are the bump stops on a 2020 Honda Civic?
They’re hidden under the dust boots on the shock absorber shafts. Up front (MacPherson strut), the bump stop slides over the damper rod beneath the boot. In the rear (multi‑link), it’s on the shock shaft as well. You’ll usually need to unseat the boot or remove the damper to see them properly.

How long do Civic bump stops last?
Often they’ll go 100,000 km or more, but lifespan depends on road conditions, loads, and whether the shocks are leaking. If the foam is cracked, crumbling, oil‑soaked or permanently compressed, it’s time to replace—ideally when doing shocks so everything is fresh together.

Can the Civic be driven without bump stops or with lowered springs?
Driving without bump stops isn’t recommended—they’re part of the Civic’s tuning and protect the suspension on big hits. With lowered springs, correct bump stop length and rate is critical. The wrong setup can cause frequent bottoming, harshness, and reduced grip, so match the stops to the new ride height and damper stroke.
