Spring Bush

Caravan spring bushes are vital components in the suspension system that cushion impacts, absorb vibration, and maintain proper alignment.

They are typically made from nylon, polyurethane, or steel, and their selection depends on your spring width and shackle bolt size.

Material Types

The material chosen affects ride quality, durability, and maintenance needs.
Nylon Bushes: These are a common, inexpensive option, often used in standard caravan and trailer setups.

They are typically non-greaseable and suitable for light-duty, on-road use. A common product is the Nylon spring shackle bush 5/8inch 45mm spring, available from suppliers like Couplemate Trailer Parts.

Polyurethane Bushes: Praised for their strength and longevity, these are ideal for heavier caravans, off-road conditions, and long-distance touring. They are resistant to oils, water, and abrasion, offering firmer handling and greater stability. The SuperPro Leaf Spring Bush Kit is a highly-rated polyurethane option, known for being durable and well-made.
Steel/Bronze Bushes: These are heavy-duty options that often require greasable (wet) shackle bolts to ensure smooth operation and longevity. An example is the 60mm Outback Spring Bush, a high-tensile steel bush used in off-road applications.
