Parts for your 1987 Suzuki Jimny-Bump stops

1987 Suzuki Jimny (Sierra/SJ413) bump-stops

Yes—bump-stops are absolutely used on the 1987 Suzuki Jimny (sold locally as the Sierra/SJ413). Technical sources including the Suzuki SJ413/Sierra Factory Service Manual (suspension section), the period Suzuki parts microfiche/parts catalogue, and mainstream workshop guides like the Haynes Suzuki SJ410/SJ413/Samurai manual all show front and rear rubber bump-stops mounted to the chassis to limit solid axle up-travel. They’re a normal part of the leaf-sprung suspension on this model and are there from factory.

On this ’87 Jimny, bump-stops act like soft landings for the axles. When the springs compress hard—think rutted tracks, a whoops section, or hitting a pothole—the stops prevent metal-to-metal contact, protecting spring packs, shocks, chassis rails and the diff housings. They also keep tyre-to-guard clearance in check and help the shocks stay within their usable stroke, so you don’t smash a shock on full compression. In short, they save parts, save money, and make the ride less harsh when things get bouncy.

Servicing-wise, they’re simple but worth a look every time the Jimny’s up on stands for a fluid change, brake check, or wheel rotation. Factory-style stops are rubber blocks bolted to the chassis, with age they can crack, harden, or tear. If they’re perished or missing, replace them before the next off-road run. It’s a cheap job with basic spanners and penetrant, and a dab of anti-seize on the hardware makes the next change easy.

• Check for splits, chunks missing, or flattened/hard rubber.
• Confirm mounting studs and brackets aren’t bent or rusted out.
• Inspect shock and brake hose clearances at full droop and full stuff.
• If the Jimny is lifted, choose extended bump-stops to suit the new travel and protect longer shocks.

Don’t ignore ride changes—clunks on hard bumps, tyres kissing the guards, or dented spring clamps often point to dead bump-stops. Replacements are straightforward: support the axle, unbolt the old stoppers, clean the pad on the chassis, then fit new OEM or quality polyurethane units to the specified height. Matching the stop height to spring arch and shock length keeps the suspension geometry happy and the truck dependable, whether it’s a beach run, a Coromandel gravel road, or a weekend up the High Country.

Popular questions

Do the 1987 Jimny/Sierra have front and rear bump-stops from factory?
Yes, both axles have them. The factory service manual and parts catalogues show rubber compression stops on the chassis above each axle to limit up-travel on the leaf-sprung setup.

How often should bump-stops be replaced on an ’87 Jimny?
There’s no fixed kilometre interval—inspect them at each service. Replace when the rubber is cracked, hardened, torn, missing, or if you’re hearing harsh bottom-outs. Off-road use, UV, and oils speed up ageing.

Can extended bump-stops help with a lift kit?
They can. With longer shocks or re-arched springs, extended stops protect shocks from bottoming and prevent tyre-to-guard contact. Choose heights that match your shock stroke and tyre size rather than going overly stiff or tall.
