Over time due to the high stress of holding the suspension and axle together, U-bolts can stretch in the threaded section, rust in harsh environments or if raising the vehicle a longer a U –bolt is sometimes required.
For a small investment a set of new U-bolts will give you peace of mind that your leaf springs are securely fitted to your vehicle.
When fitted poly bushes are coated with a generous amount of grease to reduce friction. The grease inside the bushes can be diluted through river crossing, harsh dusty or sandy environments which more often than not results in a noisy suspension.
Greasable shackles allow you to relubricate the bushes from an easy accessible grease nipple on the side of the shackle getting new grease to the pivot point.
