Volvo Rubber Buffer OEM 1580214

1. Introduction

In heavy-duty trucking, the smallest suspension parts often decide how long the expensive ones last. The Volvo rubber buffer 1580214 is a rear axle suspension bump stop. It limits axle travel, cushions impact loads and prevents metal-to-metal contact when a loaded truck hits a pothole, a rail crossing or a loading-dock ramp.

For fleet operators, workshops and wholesalers, OEM number 1580214 is a recurring wear item across a wide range of Volvo trucks, from the classic F10, F12 and N10 to the current FH, FM and FMX. It also cross-references to Renault Trucks 74 01 580 214.

Hebei Tongsource International Trade Co., Ltd. is the wholly-owned subsidiary of Hebei Huami New Material Technology Co., Ltd. (Beijing Stock Exchange: 920247), a manufacturer of rubber damping, sealing and engineering plastic components for commercial vehicles. This article explains what the part does, where it fits, how it is cross-referenced and how to replace it correctly.

2. Technical Details

2.1 Structure and function

The buffer is a rubber-to-metal bonded component: an elastomer body vulcanised onto a steel mounting plate with a threaded M12 stud for fixing. Published catalogue data lists a body height of 53 mm, an M12 × 1.75 stud and a 16 mm thread length.

As the axle approaches the end of its travel, the rubber compresses and stiffens progressively. This protects the leaf spring, axle and chassis crossmember, and reduces knocking noise.

2.2 Material and performance

The body is made from a natural rubber (NR) based compound, chosen for high resilience and fatigue resistance under repeated compression. A typical NR compound works from about −40 °C to +70 °C. Keep it away from oil and grease, which swell and soften natural rubber.

Bond quality matters as much as the compound. A poor rubber-to-metal bond is the main reason a buffer separates from its plate in service, so adhesion is checked on every production batch.

2.3 Performance advantages

• Progressive cushioning: absorbs shock at end of travel without a hard stop.

• Fatigue resistance: NR-based compound holds its shape under repeated loading.

• Secure bond: vulcanised adhesion between rubber and corrosion-protected steel.

• Consistent fit: M12 stud and 53 mm height match the OEM geometry.

2.4 OEM and reference numbers

The original number is Volvo 1580214, also listed as Renault Trucks 74 01 580 214. More than 20 aftermarket numbers map to the same part, including Febi 11879, DT 2.61050 and SAMPA 030.081. See Section 4 for the full list.

5. Typical Failure Symptoms

• Cracked or torn rubber: visible splits, chunks missing or deep surface cracking.

• Separation from the plate: the rubber lifts or peels off the steel base.

• Knocking on bumps: a hard clunk from the rear when driving over uneven road or under load.

• Axle bottoming out: contact marks or shiny wear where metal meets the stop.

• Permanent compression: a flattened, hardened buffer that no longer springs back.

• Loose or damaged stud: a stripped thread or a buffer that will not hold its torque.

• Uneven wear on the suspension: springs or brackets showing extra damage on one side.

7. Installation Notes

Step 1 — Prepare. Park on level ground, chock the wheels and support the chassis on stands. Never work under a truck held only by a jack.

Step 2 — Remove. Unscrew the old buffer and inspect the mounting bracket for cracks, corrosion or deformation.

Step 3 — Check the thread. Compare the new stud with the old one. Some catalogues list M12 × 1.75 and others M12 × 1.5, so confirm the pitch before fitting.

Step 4 — Clean. Remove dirt and rust from the seat. Keep oil and grease off the rubber.

Step 5 — Fit and torque. Tighten to the torque in the Volvo workshop manual. Do not over-tighten; it can strip the thread or crush the rubber.

Step 6 — Replace in pairs. Change the buffers on both sides of the axle so the stop height stays even.

Step 7 — Re-check. Inspect the fitting after the first few hundred kilometres under load.

8. FAQ

8.1 Which trucks use OEM number 1580214?

It fits Volvo F7, F10, F12, F16, N10, N12, NL, FL, FM, FMX and FH trucks, and Renault Trucks T, C and K. See Section 3 for years.

8.2 Is 1580214 the same as Renault Trucks 74 01 580 214?

Yes. Both numbers refer to the same part in the catalogues we checked. Confirm by VIN for your truck.

8.3 Are Febi 11879 and DT 2.61050 interchangeable with 1580214?

They are listed as replacements for OEM 1580214. Dimensions and thread can vary slightly between makers, so compare the drawing.

8.4 Why do some listings show M12 × 1.75 and others M12 × 1.5?

Manufacturers publish different thread data for this part. Measure the old stud or ask us for the drawing before ordering.

8.5 How do I know the buffer needs replacing?

Look for cracks, torn rubber, separation from the plate or a flattened body. A knock over bumps is a common warning sign.

8.6 Can I replace only one side?

You can, but replacing both sides keeps the stop height and axle travel even. We recommend pairs.

8.7 Can Tongsource supply samples and small trial orders?

Yes. Send us the OEM number and your target quantity and we will reply with samples and a quotation.
