Suspension & Steering Parts: Car Suspension Parts, Steering Systems, and Automobile Suspension Components

What Your Vehicle's Suspension and Steering System Actually Does

The automobile suspension system is not merely a comfort feature. It is a precision safety structure that manages stability, tyre contact with the road, braking performance, and load distribution at every moment of driving. When any single component begins to fail, the effects spread through the entire automobile suspension system, accelerating wear on neighbouring parts and compromising the vehicle's behaviour under braking and cornering.

The suspension of the car and its steering counterpart operate as one interconnected unit, divided into two core functions:

• The suspension system absorbs road impact, controls body movement, and maintains ride height under varying loads.
• The steering system translates the driver's input at the wheel into precise directional response at the tyres.

Both systems share common pivot components, including bushings, ball joints, and control arms, which is why a single worn part often presents symptoms across both handling and steering at the same time.

Dampers, Springs, gs and Ride Support Components

These are the load-bearing and shock-absorbing parts at the core of how your vehicle rides. Failure in any of these components affects not just comfort but vehicle safety and tyre wear.

Shock Absorbers

Shock absorbers control the oscillation of your springs after an impact, preventing continuous bounce and maintaining tyre contact with the road surface. At CBT Auto Parts, shock absorbers from Monroe, Dobinson, and OEM-spec suppliers are available across car, truck, and 4WD applications. Electronic shocks and rubber bushing shock absorber configurations are stocked, with front and rear options covering a wide vehicle range.

Struts

A strut integrates the function of a shock absorber with a structural suspension role, making it a critical component in MacPherson strut assembly designs found across the majority of modern passenger vehicles. We carry front struts, rear strut assemblies, and complete strut replacement options that simplify the replacement process and protect wheel alignment geometry.

Coil Springs

Coil springs determine ride height and carry the weight of the vehicle body. Whether you need a standard automotive coil spring for a daily driver or lowering springs for a performance application such as a Focus ST, Mustang, or MK7 GTI, the spring rate must match the vehicle's suspension design. Our car coil spring range spans OEM replacements through to aftermarket performance setups.

Leaf Springs

Leaf springs are the heavy-duty spring format used on trucks, utilities, and trailer axles where load-carrying capacity is the priority. We carry parabolic leaf spring options, trailer leaf spring kits, and leaf spring bushings for platforms, including the Silverado, Jeep YJ, and commercial trailer axles.

Air Suspension System Components

Air suspension replaces or supplements conventional coil springs with pneumatic bladders, enabling ride height adjustment and load-levelling capability. It is a popular choice on RAM trucks, luxury SUVs, and custom builds that demand a variable ride profile.

Air Suspension Components

This covers the mechanical and electronic elements of an air ride setup, including air suspension compressors, air lines, ride height sensors, and control modules. Our air suspension kits cover RAM 1500, RAM 2500, and RAM 3500 fitments, as well as rear air suspension options and general air ride suspension kits for custom applications.

Suspension Air Bags

Suspension air bags are the pneumatic chambers that replace or supplement coil springs in an air ride system. Our range includes airbag suspension kits for the Chevy Silverado 1500, RAM 1500, and classic builds like the 1969 Chevy C10. Load assist air bag options are also stocked for trucks and work vehicles needing additional payload capacity.

Steering Linkage and Suspension Geometry Components

These components control how your wheels are positioned relative to the chassis and how your steering inputs are transferred to the road. Wear in this group causes vague steering, premature tyre wear, and geometry instability.

Control Arms

Control arms are the pivoting structural links between the wheel hub and the vehicle chassis, guiding the wheel through its full range of suspension travel. We stock lower control arm and upper control arm assemblies, including options with pre-fitted ball joints for a complete replacement. Front and rear options are available for passenger cars, utes, and trucks across most common platforms.

Ball Joints

Ball joints are the rotational pivot points between the control arms and the steering knuckle. A worn ball joint produces a distinct knock over bumps and, in severe cases, can result in sudden wheel detachment. Our ball joint range covers upper and lower fitments for RAM 2500, Ford F-250, Ford Territory, and a broad range of cars and SUVs.

Sway Bars

The sway bar, also known as the anti-roll bar, links the left and right sides of the suspension to resist body roll during cornering. We stock front sway bars and rear sway bars, adjustable panhard rods, Whiteline sway bars, and heavy-duty panhard bar kits for lifted 4WDs, including the GU Patrol.

Sway Bar Links

Sway bar links, also called drop links, connect the sway bar to the suspension leg or control arm. They are a frequent wear item on vehicles driven on rough terrain. Standard and adjustable sway bar link options are available for front and rear fitment across a wide vehicle range.

Tie Rod Ends

Tie rod ends transmit the lateral movement of the steering rack into directional change at the wheels. Inner tie rod and outer tie rod options are stocked, including heavy-duty tie rod replacements for Jeep Wrangler, Land Cruiser 80 Series, and heavy-duty Chevy truck builds.

Steering Mechanism Components

The steering mechanism translates driver input from the wheel through the column, rack,k or box, and power assistance hardware into directional movement of the vehicle. Failures here affect steering precision, vehicle control, and driver fatigue.

Rack & Pinion Assemblies

The rack and pinion assembly converts the rotational motion of the steering shaft into the lateral movement that turns the wheels. Power steering rack options are available for the Volvo XC90, VW Golf Mk4, Subaru WRX STI, and VW Jetta, among others, alongside manual rack and pinion assemblies for vehicles without power assistance.

Steering Columns

The steering column carries driver input from the steering wheel down to the rack or box through the steering shaft and intermediate shaft. OEM and aftermarket steering column options are stocked for Vauxhall Corsa, VW Touareg, VW Passat, and Chevy truck applications, including electric steering column replacements for modern conversions.

Power Steering Pumps & Hoses

The power steering pump generates the hydraulic pressure that makes steering manageable at low speeds, while power steering hoses carry fluid between the pump and the rack under sustained pressure. Our range includes electric power steering pump options such as ZF electric power steering pumps, semi-truck power steering pump replacements, and complete power steering hose sets.

Steering Boxes

Steering boxes use a recirculating ball steering mechanism and are the standard configuration on trucks, commercial vehicles, and older passenger cars that do not run a rack and pinion setup. Heavy-duty steering gearbox options are available for trucks, classic builds, and electric power steering gearbox conversions.

Steering Knuckles

The steering knuckle, also called a spindle assembly, is the pivot component that joins the wheel hub, ball joints, and control arms. Front steering knuckle and rear steering knuckle options are stocked for Honda Civic (2002, 2003, 2005), Mazda 3, Ford Focus, and Subaru Forester platforms.

King Pins

King pins are the vertical pivots used in solid axle and commercial vehicle steering systems, performing the function of ball joints in those applications. Semi-trailer kingpin options, Holland kingpin placements, and Chevy Dana 60 kingpin kits are available for both commercial and solid axle conversion builds.

Wheel Hub and Bearing Assemblies

Your wheels do not simply bolt to the vehicle. They sit on bearing assemblies that allow rotation while managing the full weight and cornering loads of the vehicle. Worn components here are a direct safety concern.

Wheel Bearings

Wheel bearings allow frictionless wheel rotation under load. A worn bearing typically produces a humming or grinding noise that intensifies with vehicle speed. Hub bearing assemblies, front hub bearing assembly options, and trailer wheel and hub assembly sets are all stocked, alongside complete wheel bearing hub assembly replacements covering a wide vehicle range.

Wheel Hubs

The wheel hub is the mounting surface for the wheel and the housing for the bearing assembly. Wheel hub assembly and hub assembly options are available for passenger vehicles, utes, and trailers. Whether it is a single hub replacement or a full hub assembly with bearing included, our range covers the most common applications.

Suspension Bushings and Repair Kits

Bushings and suspension repair kits are among the most cost-effective ways to restore handling precision and ride quality on high-kilometre vehicles without replacing entire assemblies.

Bushings

Suspension bushings are the rubber or polyurethane sleeves installed at every pivot point across the suspension system. They control movement, absorb vibration, and prevent metal-to-metal contact. Our range includes SuperPro bushes, polyurethane bushings, and standard suspension bushes for lower control arm bushings, rear differential mounts, and shackle bushings. Polyurethane suspension parts from brands like SuperPro are widely chosen for their extended service life in demanding conditions.

Suspension Repair Kits

A suspension repair kit consolidates the most commonly replaced components into a single purchase, making it the efficient choice for a full overhaul. We stock suspension rebuild kits and suspension overhaul kits for the VE Commodore, 65 and 66 Mustang front suspension kits, and air ride suspension kit configurations, as well as individual platform-specific repair kits across the range.
