Stabilizer bar is a part of many automobile components that helps to reduce the body roll of a vehicle during fast cornering or over road irregularities. It connects opposite (left/right) wheels together through short lever arms linked by a torsion spring. The stabilizer bar extends across the front underside of the chassis and connects to the frame cross member. The ends of the bar are mount to the lower suspension arm. All mounting points of the stabilizer bar are isolated by bushings.

  Spring pins is used to retain a shaft as a journal, and act as mechanical fastener that secures the position with leaf spring & Bracket /Shackle relative to each other. The spring action of the pin allows it to compress as it assumes the diameter of the hole and force exerted by the pin against the hole wall retains it in the hole, therefore a it is also considered a self-retaining fastener.

A lift axle is a way in which the axle can be raised so that its tyres aren't touching the road surface. This improves fuel economy, and reduces maintenance and tyre wear, although it increases road wear. The advantage of a lift axle is that it provides more scope for carrying heavier loads without having negative impacts when the truck and/or trailer are empty. The lift axle's function is to raise and lower the axle with the compressed air used by the trailer. It improves the efficiency of the trailer operation by grounding and floating the tires. This is made possible through a sensor which perceive the weight burdened on the axle. Air will be automatically filled up with the air suspension when the sensor perceives that the cargo weight is lighter than the certain amount.

Shackle Bracket is part of leaf spring assembly, which accommodates leaf deformation, i.e. when subjected to operational load it's allow leaf spring's length changes during suspension articulation. It is an integral component of the suspension system that attaches between leaf spring and vehicle frame. It help you get the stability under dynamic condition as well. They act as a part which holds hanger & spring assembly together.

A Parabolic Z-Spring suspension system is composed of many components that are designed, created and assembled together in a manner that every component works together to soften the effects of rough road conditions, improve the comfort of the ride and protect other parts of the vehicle by absorbing and reducing the shocks and vibrations. This improve driving condition makes handling vehicle easier which ultimately improves safety.  The right suspension system also allows a vehicle to stay grounded which further improves handling and safety.
