Ironman Polyurethane Bushes feature a unique high density injection moulded polyurethane material, providing precise location and a durable bearing surface for your leaf springs, making them very durable in hot temperatures whilst providing soft comfortable vehicle ride.
All Ironman spring bushes also feature the special spiral and flange grooves - incorporated grooves and spiral bore rifel - to distribute lubricating grease evenly throughout the bushing surface when combined with greasable shackles and pins.
Ironman Adjustable Offset caster Bushes are made from a high density injection moulded Polyurethane and laser cut notched Steel Tube. Easy to fit and adjustable to 3 different settings, Standard, 2.5 Degree & 3.5 Degree. Adjustment is achieved by the rotation position of the inner steel tube. caster angle is the backward or forward tilt of the differential steering axis. Positive caster is needed in most applications within front suspension in 4x4 vehicles. When a vehicle is lifted via raised springs, this positive angle is reduced. The reduced caster angle will detract feeling and response through the steering wheel. This will also cause reduced self-centring and possible wheel shimmy in extreme cases. The offset in the bushes will tilt the differential (positive) back toward manufacturers specification thus greatly improved handling and feel. Highly recommended for raised height 4x4`s up to 75mm lift to permanently cure vehicle wonder.
