What Do The Different Grades Mean?

When There’s No Option Available:

We’ve selected the material that offers the best balance of performance and comfort for your vehicle’s needs.

Comfort (Blue 65A):

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.

Dynamic (Orange 75A):

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 (RED 85A):

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!

Machinable Material:

These rods are produced in 90 Shore A which allows them to be machined on a lathe.

Specifications

Upgrade your Land Rover Defender L663, fitting the 90, 110 & 130 (2020-onwards) with high-performance polyurethane suspension bushes from Polybush. Designed to replace OEM part LR113306, our Front Lower Front Arm Bush (Code: 1DU) is engineered for strength, durability and improved handling – ideal for both daily driving and off-road adventures.

Where the original rubber bushes can wear out prematurely – especially under load or rough terrain – our polyurethane alternative offers greater longevity, better control, and consistent suspension geometry. Whether your Defender is used on the road, towing, or off the beaten track, this upgrade helps reduce unwanted movement in the lower control arm, improving steering response and maintaining alignment.

Proudly manufactured in the UK, our bushes are a direct fit with no special tools required and are built to withstand the rigours of modern Land Rover use.

Key Benefits:
Direct replacement for LR113306
Enhanced durability over standard rubber bushes
Sharper handling and improved ride quality
Resistant to oil, fuel, road grime, and temperature changes
Easy DIY or garage install
Ideal for enthusiasts who want to protect their investment, improve performance, or simply avoid premature wear.
