TRW endurance tests highlight concerns over quality

ZF Aftermarket brand TRW claims there is an “influx of low-quality suspension parts” entering the aftermarket, and is urging bodyshops and technicians to prioritise quality and safety, particularly as demand increases.

To back up its claim and to “highlight the importance of quality”, TRW said it recently conducted a series of “rigorous endurance tests, revealing the superior performance of its products compared to competitors”.

For example, in the tie rod endurance test, TRW suggests its parts successfully passed 1,000,000 cycles without any fracture or cracking. Similarly, TRW’s control arms are said to have completed 500,000 cycles without any signs of wear or damage.

In contrast, TRW claims competing products failed to meet the “same high standards, particularly in critical areas such as torque performance and ball stud retention”.

According to TRW, its “in-house production and rigorous testing processes offer the aftermarket industry the reassurance of unparalleled quality and reliability”.

Mark Hallam, marketing manager at ZF Aftermarket, said: “As the aftermarket braces for a busy season, it’s essential that workshops remain vigilant about the parts they choose. Inferior components may appear cost-effective initially but can lead to costly and dangerous failures down the line.

“TRW’s commitment to quality and safety ensures that our customers receive products that meet – and often exceed – the highest industry standards.”

TRW boasts a comprehensive range of linkage and suspension parts. So far this year, TRW has launched 13 stabiliser links, 12 ball joints, 65 control arms, 20 tie rod ends, and 10 axial tie rods – with 120 additional part numbers in the launch process and another 80 in preparation.

The ZF brand also provides workshops with ongoing support, including training, guidance and installation instructions, ensuring technicians are fully equipped to handle the increasing complexity of modern vehicles.
