Parts for your 2015 Nissan Navara-Bump stops

2015 Nissan Navara bump-stops — what they do and when to replace them

Based on technical sources, bump-stops absolutely are fitted to the 2015 Nissan Navara (D23/NP300). The Nissan D23 Series (2015) Service Manual names them as “Bumper – Jounce” in the Front Suspension (FSU) section and as “Bump Stopper” in the Rear Suspension (RSU) section. The Nissan Electronic Parts Catalogue (EPC) for the 2015MY also illustrates these components for both front and rear setups, across coil- and leaf-sprung variants. Major aftermarket parts catalogues for the D23 list direct-fit front jounce bumpers and rear axle bump stops as well.

On the 2015 Navara, bump-stops act like compact safety cushions. They prevent metal-to-metal contact at full compression, protect shocks, control arms, springs and the chassis, and help keep handling predictable when the ute bottoms out over big hits, towing or carrying heavy loads. The fronts are typically mounted to the chassis or lower control arm as jounce bumpers, while the rears sit above the axle (leaf or coil rear variants both use them) to cap the last bit of travel and maintain clearance for tyres and driveline bits.

As part of routine servicing, they’re quick to check and cheap insurance for the rest of the suspension. Look for perishing, cracks, chunks missing, hardening, or the bump-stop permanently “squashed” and not rebounding. If a bump-stop has detached from its bracket, or if there’s fresh witness marks where the axle or arm is hitting the frame, it’s time to replace.

• Inspection: have them checked at every service or tyre rotation, and always after harsh off-road use, beach work, or big towing trips.
• Replacement triggers: visible cracking, oil contamination from a leaking shock, collapsed or missing bump-stops, or frequent bottoming-out noises.
• Fitment tips: clean the mounting face, use new hardware where specified, and torque to the values in the Nissan service manual. If a stop uses a press-in or keyed mount, ensure full seating and correct orientation.
• Upgrades: progressive or microcellular polyurethane bump-stops can smooth the last portion of travel and help with load support, but they’re not a substitute for tired springs or shocks.

Keeping the Navara’s bump-stops healthy helps the shocks last longer, reduces harshness at full bump, and protects alignment and bushes from hard hits — a small part that makes a big difference on Aussie and Kiwi roads and tracks.

Popular questions about 2015 Nissan Navara bump-stops

Does the 2015 Navara definitely have bump-stops?
Yes. The Nissan D23 (2015) Service Manual lists front jounce bumpers and rear bump stoppers, and the Nissan EPC shows them in both front and rear suspension diagrams. Aftermarket catalogues also supply direct-fit replacements, confirming they’re standard equipment.

How often should they be inspected or replaced?
Have them inspected at each service or at least every 10,000–15,000 km, and after heavy off-road or towing work. Replace when cracked, hardened, oil-soaked, deformed, missing, or if the vehicle is bottoming out. There’s no fixed kilometre interval — condition and use are the best guides.

Will upgraded bump-stops help with heavy loads?
Progressive bump-stops can soften the hit at full compression and add a bit of support when loaded. They can improve control and comfort, but they won’t fix sagging springs or worn shocks. For regular heavy hauling, consider springs and shocks rated for the job, with the bump-stops as part of the overall setup.
