Bulky Truck Parts Require Extra Care and Maintenance


A vehicle that conveys the heap without anyone else, without a trailer is known as a truck. Vehicles exceeding 26001 pounds are known as heavy duty trucks, such as city transit buses, cement mixers, dry vans, and other vehicles. These type of vehicle are primarily used for heavy-duty use and can be categorized as follows:

Class7 – 26001 to 33000 pounds

Class 8- 33001 or heavier

Class9 – Vehicles of more than 60,000 pounds 

Understanding the class of vehicles is necessary for safety and compliance needs as specific laws, rules, and regulations are prevalent depending upon the class of trucks. It also determines the maintenance and repair that are required on the vehicle.

The Raw Materials Used In The Manufacture of Heavy-Duty Truck Parts are :

  • Trucks use steel for the body for strength and durability, aluminum as it is lightweight and non-corrosive, stainless steel for a bright finish, and plastic for complex shapes.
  • High-tensile steel is used for cross members and frame rails. 
  • Either cast or fabricated and welded steel is used to produce suspension components, axles, and engine mounts.
  • The outer structure is made from either steel or aluminum. The steel, if used, is coated with another layer to prevent corrosive substance.
  • The front fenders are plastic molds because of the complex shape.
  • The front bumper may be drawn from steel or aluminum or plastic molded with the support of a steel substructure.
  • Other parts such as outside mirrors, handles, sun visors are usually made from stainless steel to ensure longevity and durability.
  • The interiors are generally designed using cloth or vinyl, and the floors are covered with fiber or rubber mats. 
  • The dashboard is made from molded plastic, and windows are made up of laminated safety glass.

The present most well known substantial truck was monetarily evolved during the 1910s. Most heavy duty truck parts move along an assembly line in today’s date, where different components are added to by various workers. The assembly line starts with a frame that serves as the backbone of the production and finishes as a fully operational vehicle.

The Typical Activities Of An Assembly Line Are:

  • The casings are amassed first; robotized machines are modified to interface cross-part sections, motor mounts, and other casing mounted segments. Then the axles are clamped to suspension, and the shock absorbers are installed between the shaft and the frame.
  • The frame is now put on free support and is ready to move down the assembly line; this frame with the axles, suspension, and the other mounted components are known as chassis.
  • The frame is then painted utilizing air shower firearms, and all the parts which are not to be painted are secured with covering tape or paper. 
  • After the paint dries and the masking tape or paper is removed, the chassis moves down the assembly line to install the engine.
  • Almost all the heavy duty truck parts use a diesel engine, the clutch, fan, alternator and other parts of the engine are then introduced, and then the fuel lines, air hoses, coolant hoses, and starter cable are connected to the engine.
  • After finishing the chassis, the cab, hood, and sleeper are assembled, where the cab and sleeper substructure are welded. The hood is usually a molded piece of plastic required for rough surfaces sanded as necessary.
  • The following stage of the mechanical production system is to paint the taxi, hood, and sleeper and introduce it. 
  • After all the associations are finished, the hood is brought down on the suspension and made sure about its turn point. 
  • The engine and other reservoirs are filled, steering wheels are installed, and batteries are connected, and the truck is now ready to be driven off the assembly line for a test drive.

Heavy-duty truck designs and parts keep evolving in a few years, better parts or models that make the trucks fuel-efficient or improve the performance are bought in the market.Some of the popular brands, when it comes to heavy duty trucks parts companies are Jones performance, Valley Chrome, Titan Hoods, AlphaRig, Depo, Fuel Tanks, Protech,Acme Corporation, Eagle Eyes,AlumiTank, United Pacific and Trux. Heavy-duty trucks are one of the most conservative methods of delivering a wide assortment of materials all around, its economical nature is the reason for it’s worldwide popularity.
