Broad range

Today’s modern vehicles contain many different rubber-to-metal components, which is why we’re focused on the continued development of our range. Our current line-up includes control arm and suspension mount bushes, anti-roll bar bushes and engine mounts … with more to come.

The right material

Rubber-to-metal components are subject to high dynamic stresses day-in, day-out. And is why we only ever use the highest quality materials. By carefully balancing the precise quantities of steel and rubber, our rubber-to-metal parts provide the optimum combination of strength, flexibility and noise reduction, tailored to the application they fit.

Preparation is key

To ensure a perfect bond between rubber and metal, both materials go through a rigorous cleaning process. All bonding surfaces are washed, sanded, degreased and painted. And that’s just the start.

Super strong bond

For superior mechanical properties, we chemically bond the rubber to a pre-coated metal surface. Under high temperatures and pressure, the adhesive reacts to provide a powerful bond between the rubber and metal part – so much so, that the rubber should tear before the bond breaks.

Pushed to the limit

We know our parts are strong and durable, but just to be sure, we subject them to extensive fatigue testing. We also conduct push tests to check the cohesion of the rubber to metal. As a rule, OE push out levels for bushes are 1000 Nm of pressure minimum. Ours can withstand 1800 Nm.

Three-year warranty

Available in UK only. Like all our steering parts, our rubber-to-metal range comes with a three-year or 36,000-mile warranty. So you can fit Delphi with complete confidence, for an OE quality repair you know will last.

Rubber to Metal Durability Test

Confirms the integrity of the part design and manufacturing process used to make it.
After 220,000 test cycles, the Delphi bush remained intact with a small amount of rubber cracking.
In contrast, one competitor suffered a complete failure of the bonding in less than 30,000 cycles.
This can result in the failure of the component assembly into which it is installed.

Why suspension components take so much punishment and how to spot when they need repairing

In this piece, we’ll look at seven critical components within a vehicle’s suspension system, and what can go wrong with them.

Symptoms of poor or damaged suspension

One of the most obvious signs that a vehicle’s suspension needs attention is when your customer can feel bumps in the road more acutely. Suspension is a complex, multi-component system on the vehicle and this can add difficulty for the customer to describe the squeak, groan, or grind noise they’re experiencing. It’s best to replicate the fault on a short test drive with the customer if you can, to be sure you’re identifying what they’re reporting. This test drive time can be accounted for in the technician’s time, can increase first time diagnosis FTD, and can make all the difference in a positive customer service experience too.

An obvious symptom is when the vehicle drifts or pulls during turns. This means that the shocks are no longer up to the job of keeping the vehicle body stable when it’s turning. In extreme cases (and this is particularly true of commercial vehicles), this increases the chances of losing control of the vehicle, or even turning it over.

Problematic suspension can also increase stopping distances by up to 20% - a serious hazard. If your customer has noticed the vehicle’s bonnet lurching downwards while stopping, it’s a clear sign that the suspension needs attention.
