Suspension bushes in focus with Polybush
When it comes to vehicle suspension, says Polybush, the smallest components often have the biggest impact.
“Suspension bushes, although relatively simple parts, play a crucial role in maintaining the ride comfort, handling, and overall safety of a vehicle,” said the company.
“For years, mechanics have wrestled with the limitations of traditional rubber bushes—leading to frustrated customers and repeat repairs.
“Polyurethane suspension bushes, like those produced by Polybush, represent a smarter, longer-lasting solution.”
Rubber has been the go-to material for suspension bushes since the earliest days of the automobile, says Polybush.
“Its initial flexibility allows it to dampen vibrations and noise effectively, but it comes with a significant drawback: rubber degrades over time (which can be as short as 6 months).”
Contributing factors highlighted by Polybush include environmental damage, and the tendency of rubber bushes to soften and deform with repeated compression.
Polyurethane addresses all the shortcomings of rubber, says the firm, and provides several unique advantages.
“Polyurethane is immune to oil, grease, UV, and weather conditions and is far more resistant to deflection than rubber,” it said.
“Polybush bushes have been proven to last well over 10 times longer than traditional rubber bushes, with some lasting hundreds of thousands of miles…
“Unlike rubber, polyurethane doesn’t suffer from significant compression set or deformation. This stability ensures consistent handling, improved steering response, and reduced tyre wear—factors that are especially crucial for performance vehicles and workhorses like vans and 4x4s…
“While rubber bushes crack or disintegrate within a few years, Polybush products continue to perform for decades, reducing the need for replacements and callbacks.”
A further claimed benefit of Polybush bushes is easier and quicker fitment compared to other aftermarket options. They are designed to be installed with only basic workshop tools, unlike some products that require hydraulic presses or specialised equipment. Polybush bushes also come pre-lubricated, and many feature a split design for easy fitment.
“When you fit Polybush, you’re not just installing a bush—you’re giving your customer peace of mind,” said the company.
“You’re fitting a product that won’t come back to haunt you after a few months, saving time and boosting customer satisfaction.”
