At Polybush, we’re excited to announce our latest product release — high-performance polyurethane suspension bushes for the Land Rover Defender L663, covering the 90, 110 and 130 models from 2020 onwards.
Whether taking on tough terrain or simply navigating the school run, your Defender deserves a suspension setup built to last. That’s where Polybush steps in.
One of the most common points of failure on the modern Defender L663 is the front lower front arm bush, part of OE reference LR034219. Designed to replace a long list of OEM part numbers — LR034220, LR072468, LR072469, LR072470, LR072471, LR073463, LR073465, LR109038, LR109039, LR113306, LR113307, LR113702, LR113703, LR126101, LR126102 — our polyurethane Front Lower Front Arm Bush (Polybush Code: 1DU) is engineered to outperform the original rubber in every scenario.
Rubber bushes can wear out rapidly, especially when faced with the strain of towing, heavy loads, or rugged off-road driving. This leads to vague steering, alignment issues and a rougher ride.
Our polyurethane alternative is designed to retain comfort while delivering enhanced performance and longevity. The result? Sharper handling, reduced bush deflection and dependable suspension geometry — whether you’re on the road or exploring off the beaten path.
Direct replacement for LR113306 – fits without modification
Longer lasting than OEM rubber – no more premature wear
Improved handling and ride quality – perfect for daily driving and off-road
Resistant to oil, fuel, road grime and extreme temperatures
DIY-friendly installation – no special tools required
From utility to luxury, the Defender L663 is a serious bit of kit. But even the best needs proper support. Our bushes are ideal for:
Road-going Defenders that need precise, reliable suspension
Adventure builds that tackle trails, ruts and river crossings
Towing applications where stability and alignment matter
If you’re fed up with replacing tired rubber bushes or want to tighten up your Defender’s handling without sacrificing comfort, our polyurethane bush kit is the smart upgrade. No squeaks, no compromises — just robust, road-ready performance that lasts.
