Engine & Powertrain Parts | Car, Diesel & Automotive Engine Parts

What Are Engine & Powertrain Parts?

The engine is the heart of any vehicle, and the powertrain is the system that converts combustion into movement. Together, they include dozens of precision components that must work in exact coordination to deliver power, efficiency, and durability. When any one of these auto engine parts wears out, the entire system feels the impact from poor performance and misfires to catastrophic engine failure if left unaddressed.

At CBT Auto Parts, our engine spare parts range is structured around the full powertrain family so you can find exactly what you need without confusion. Below is a complete breakdown of every component category we carry.

Engine & Powertrain Parts We Carry

Pistons

Car pistons are among the most high-stress components in any engine. They move thousands of times per minute inside the cylinder, converting combustion energy into mechanical force. We stock standard, forged, and diesel piston options for a wide range of applications, whether you need a direct replacement or an upgrade.

Piston Rings

Piston rings seal the combustion chamber and regulate oil consumption. Worn or broken piston rings lead to blue smoke, poor compression, and oil burning. Our engine piston ring sets are available for petrol and diesel engines, including heavy-duty and truck applications.

Connecting Rods

Connecting rods link the pistons to the crankshaft, bearing some of the highest mechanical loads in the engine. We carry standard and forged connecting rods, including H-beam and I-beam designs, with diesel and petrol con rod options available across multiple engine families.

Crankshafts

The car crankshaft converts the reciprocating motion of the pistons into rotation. We stock forged, billet, and automotive crankshaft options built for both factory replacements and performance builds. Each crankshaft is precision balanced and dimensionally verified before dispatch.

Main Bearings

Main bearings support the crankshaft within the engine block, keeping it centred and reducing friction. Worn main bearings are a common cause of engine knock. Our range includes crankshaft main bearings, rod and main bearing kits, and brand options such as King and Taiho across a range of engine codes.

Rod Bearings

Rod bearings, also known as big end bearings, sit between the connecting rod and the crankshaft journal. Failures here often announce themselves as a deep knock. We supply rod bearing kits and individual sets compatible with most common petrol and diesel engines.

Camshafts

Engine camshafts control the timing of intake and exhaust valve operation. Whether you need a direct OEM replacement or a performance camshaft for a modified build, our range includes VVT camshafts, aftermarket grinds, and application-specific options for trucks, four-wheel drives, and performance vehicles.

Cylinder Heads and Gaskets

Cylinder heads house the combustion chambers, valves, and coolant passages. A blown head gasket or warped head will take an engine off the road fast. We stock cylinder heads and head gaskets, including Cometic head gasket options, for a broad spread of diesel and petrol engines.

Engine Gasket Kits

For full rebuilds or top-end work, a complete engine gasket kit ensures every sealing surface is refreshed in one go. We carry full gasket sets and top-end gasket kits for LS, Cummins, Chevy, and many other platforms, eliminating the need to source individual gaskets separately.

Timing Belts and Chains

The timing belt or timing chain keeps the crankshaft and camshaft synchronised to within fractions of a degree. Failure here is catastrophic. We carry timing belt and timing chain kits across a wide range of makes including Toyota, Ford, Hyundai, and Subaru, as well as cambelts, tensioners, and full timing replacement kits.

Oil Pumps

The engine oil pump is responsible for maintaining oil pressure across every bearing and moving surface in the engine. Without it, internal wear accelerates rapidly. Our range includeshigh-volumee oil pumps, standard replacement units, andMellingg oil pump options for LS and other popular platforms.

Valve Train Parts

The valve train governs how and when the engine breathes. Components in this category include rocker arms, valve springs, pushrods, valve lifters, and tappets, all available individually or as kits. Cummins-specific valve train parts are a strong part of our range.

Flywheels

The flywheel links the engine to the transmission and stores rotational energy to keep the engine spinning between power strokes. We carry billet flywheels, dual mass flywheels, and flywheel housings including Cummins ISX and 5.9 variants.

Harmonic Balancers

Harmonic balancers, also called harmonic dampers or crankshaft pulleys, reduce torsional vibration along the crankshaft. Failure leads to destructive resonance throughout the engine. Our range covers Cummins, LS, and a wide spread of car and truck applications.

Engine Mounts

Engine mounts keep the engine secured to the chassis while isolating vibration from the cabin. Worn car engine mounts cause excessive movement, noise, and drivetrain stress. We stock motor mounts for passenger vehicles, trucks, and swap applications.

Engine Sensors

Engine position sensors, crankshaft sensors, and camshaft sensors are critical for engine management. A faulty cam or crank sensor will throw fault codes, cause misfires, or prevent the engine from starting altogether. Our engine sensor range covers the most common OEM failure points across multiple makes.

Ignition System

The ignition system initiates combustion. For petrol engines, this means spark plugs and ignition coils; for diesel engines, glow plugs are the key to cold starting and combustion stability. We stock a full ignition system range including car spark plugs, diesel glow plugs, and vehicle ignition coils.

Fuel Rail

The fuel rail distributes pressurised fuel to all injectors simultaneously. Leaks, pressure loss, or blockages here directly affect fuelling accuracy and power delivery. We carry performance, billet, and OEM-spec fuel rails for Cummins, LSA, and a range of other applications.

Fuel Injectors

Fuel injectors meter fuel delivery with precision. Worn or fouled injectors cause rough idle, poor fuel economy, and emissions issues. We carry diesel injectors and petrol fuel injectors across a wide application range, including Denso fuel injectors and high-demand ZD30, 5.9 Cummins, and 6.7 Cummins fitments.

Intake Manifolds

The intake manifold distributes the air-fuel mixture or charged air evenly across all cylinders. Carbon build-up in diesel intake manifolds is a known failure point. We supply performance intake manifolds, OEM replacements, and diesel intake manifold options across multiple engine families.

Turbochargers and Superchargers

Forced induction is one of the most effective ways to extract more power from an engine. Whether you need a diesel turbocharger replacement, a variable nozzle turbocharger, or a petrol supercharger, our range covers OEM-spec and upgraded units. Wastegate solenoids and turbocharger gasket kits are also available.

Intercoolers

After compression, charged air needs to be cooled before it enters the engine to maximise density and reduce the risk of detonation. We carry front mount intercoolers, top mount intercoolers, and truck intercoolers for diesel and turbocharged petrol applications, including popular fitments for Ford Ranger, Ram 2500, and Ram 3500.

Engine Rebuild Kits

When an engine has reached the end of its service life, a complete engine rebuild kit restores it to factory specification in a single order. Our motor rebuild kits and engine overhaul kits include pistons, rings, bearings, gaskets, and seals matched to your specific engine. Cummins overhaul kits and full gasket set options are a major part of our rebuild inventory.

OEM vs Aftermarket Engine Parts: What You Should Know

One of the most common questions from buyers is whether aftermarket engine spare parts are a safe choice. The answer depends entirely on the supplier and the specification of the part.

OEM parts are made by or for the original vehicle manufacturer and carry the manufacturer's warranty. They are the benchmark. Aftermarket parts, when sourced to the correct specification and manufactured to the right tolerances, can match or in some cases outperform the OEM equivalent, particularly in high-stress applications such as forged pistons, performance camshafts, and high-volume oil pumps.

At CBT Auto Parts, every aftermarket component in our range is selected against the OEM specification. We do not list a part unless it has been verified for dimensional accuracy, material quality, and application fitment. For buyers running modified or high-output engines, our aftermarket range offers performance options that the OEM catalogue simply does not carry.
