Parabolic Spring

Basically, a parabolic spring is a spring that consists of two or more leaves. The leaves touch only in the center where they are fixed to the axle and at the outer ends, they are fixed to the vehicle. In between those two points, the leaves do not touch each other as they do with conventional leaf springs.

Conventional Leaf Spring

A leaf spring is a simple form of spring, commonly used for the suspension in wheeled vehicles. It is also one of the oldest forms of spring. Sometimes referred to as a semielliptical leaf spring (SELS) it takes the form of a slender arc-shaped length of spring steel of rectangular cross section.

Hanger & Shackles

It's a key part in centering the truck's axle and supporting the weight of the vehicle. The shackle lets the springs of the vehicle extend as the car moves through different surfaces of the roads like bumps, rocks, uneven potholes etc

Bolt & Nuts

Bolts are a type of fastener. Fasteners are used to secure or fasten materials together. There are many types of bolts and hardware nuts. Most, if not all, bolt types have machine threads. A threaded bolt screws into nuts to hold or fasten materials together.

Spring Pins

A spring pin is a mechanical fastener that secures the position of two or more parts of a machine relative to each other. Spring pins have a body diameter which is larger than the hole diameter, and a chamfer on either one or both ends to facilitate starting the pin into the hole.

Silent Block

Silent Block Bushes are very important components of an automobile, and are also known as Silent Block Bushings and Silent Block Rubber Bushes. These bushes are made from premium quality two concentric steel sleeves with rubber that ensures strong design and construction. The rubber is flowed into the gap between two sleeves in order to fill up the void and further vulcanized at constant temperature & pressure. Moreover, the pressure will be added to ensure maximum dynamic strength as well as endurance. The silent block bushes used in automobiles are capable of taking varied types of load intensity such as torsional movement, axial & radial load.



Diesel exhaust fluid (DEF; also known as AUS 32 and marketed as AdBlue) is a liquid used to reduce the amount of air pollution created by a diesel engine.



A washer is a thin plate with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener, such as a bolt or nut.
