We’ve selected the material that offers the best balance of performance and comfort for your vehicle’s needs.
Our Comfort grade bushes are designed to enhance ride quality and minimise road noise, making them ideal for everyday driving. They are softer, providing maximum suspension articulation and a cushioned feel that absorbs bumps and vibrations effectively. This softer composition ensures a smoother, quieter driving experience, especially in Classic cars or Land Rovers. Comfort bushes maintain a balance between originality and ease of driving, catering to those who value a relaxed Factory-Fresh drive.
The Dynamic grade bushes offer a middle ground between Comfort and Performance. They are slightly firmer than the Comfort bushes, which improves handling and cornering response without sacrificing too much ride comfort. These bushes are ideal for drivers who enjoy a more engaging driving experience while still needing a level of comfort for daily use, whilst also being suitable for spirited driving & light track use.
Performance grade bushes are the stiffest of the three, designed for enthusiasts who demand the utmost in handling and control. They offer minimal deflection, enhancing vehicle response and stability during aggressive driving. These bushes are perfect for high-performance or track vehicles where precision and handling are critical. While they might sacrifice some ride comfort, they deliver superior driving dynamics and control, ideal for those who push their vehicle to its limits – Including Towing!
These rods are produced in 90 Shore A which allows them to be machined on a lathe.

Specifications
The Opel Combo K9 represents the latest generation of one of Europe’s most popular light commercial vehicles, widely deployed across UK trades, delivery services, and small business operations.
Modern Combo vehicles operate in demanding commercial environments where suspension reliability directly impacts safety, cargo security, handling stability, and operating costs. Original rubber suspension bushes deteriorate under the stresses of commercial use, leading to suspension noise, vague steering response, and reduced vehicle control that compromise driver safety and comfort during extended working days.
Polybush manufactures polyurethane suspension bushes specifically engineered for the Opel Combo K9 (2018-Onwards) platform, providing exceptional durability in contemporary commercial vehicle applications. Our bushes address critical suspension attachment points: front lower arms, subframe mounting, anti-roll bar connections, and engine isolation points. Polyurethane construction offers significant advantages over factory rubber components: resistance to oil and fuel contamination from engine systems, salt spray exposure from winter road treatment, temperature extremes from outdoor parking, and mechanical fatigue from loaded cargo cycles. These superior material properties extend service life to approximately 4-5 times that of rubber bushes, directly improving business economics through reduced maintenance frequency.
Commercial operators report substantial practical benefits after upgrading to Polybush suspension bushes. Steering response sharpens noticeably, body roll diminishes during cornering even when carrying loads, and overall vehicle control improves dramatically. Cabin noise reduces as suspension components no longer rattle and clunk, enhancing driver comfort during long working shifts. Braking feel improves through firmer suspension geometry, improving safety margins when responding to traffic. The Combo K9’s contemporary platform responds particularly well to polyurethane upgrades, with operators appreciating the enhanced stability when navigating challenging terrain or congested urban environments.
Our three-tier material grading system accommodates different operational requirements and fleet priorities. Comfort-grade bushes provide refined ride quality prioritising driver comfort during extended daily use, ideal for mixed-duty applications. Dynamic-grade bushes optimise handling responsiveness and body control, suitable for Combos operating in more challenging conditions or carrying variable loads. Performance-grade bushes deliver maximum control and minimal deflection for intensive commercial operations, offering enhanced safety margins and exceptional durability.
Many commercial fleet operators adopt mixed specifications across their Combo fleet, selecting appropriate grades based on individual vehicle operational profiles and expected usage patterns. Installation utilises original mounting points without requiring suspension geometry modifications, allowing straightforward fitment during routine vehicle maintenance windows.
Whether operating a single Combo or managing multi-vehicle commercial fleets, Polybush polyurethane bushes deliver reliability, durability, and improved operational performance that rubber components cannot provide.
