TRW steering linkages

The steering linkage is a crucial part of the steering system, connecting the front wheels and enabling them to move in a functional way. Given the importance of the steering linkage, it is critical that all cars are fitted with high quality parts, which TRW can provide to help you offer great service for your customer.

With TRW Aftermarket steering linkage you get
TRW Steering linkages
  • Improved performance of tyres which lowers the chances of vehicle-roll
  • More than 4,800 parts to choose from
  • Corrosion resistant stabiliser links made from glass-fibre reinforced plastic
  • Reduced weight and damping vibrations
  • Two-seat design for tie-rod ends which means no spring and therefore longer life

Our standing as an industry leader in steering systems is highlighted by our huge product range, covering more than 4,800 parts and 92% of the European vehicle parc. This means you can trust TRW to deliver exceptionally high standards of performance and safety. The benefits of choosing a TRW steering linkage includes:

  • Guaranteed safety improvement
  • Continuous advancement through outstanding research and development
  • Original equipment (OE) quality
  • Extreme testing process
  • Expert training and guidance

If the steering linkage in a vehicle isn’t working properly then the occupants could be in danger. The chances of vehicle-roll during cornering are increased by a failing stabiliser link due to possible over steer, while a broken stabiliser link can also knock out or tilt away. As well as generating an annoying noise while the vehicle is running, a damaged steering linkage could affect the performance of the tyres or braking, which also has the potential to be dangerous for the driver.

With a wide and varied product range, we cover a huge selection of requirements, which is why we’re your one-stop solution in the aftermarket. Manufacturing all sorts of linkage products from Tie rod ends to control arms and ball joints, we have developed forged aluminium, forged steel, nodular cast iron and stamped steel to give you lightweight parts for efficient and flexible performance.

With corrosion resistant stabiliser links made from glass-fibre reinforced plastic, you can give drivers safe, efficient and strong performances at all times. The use of such high-quality materials allows us to reduce the weight and damping vibrations of our stabiliser links. And where glass fibre material is unsuitable due to space restrictions, we’ll supply proven steel steering linkages.

Our tie rod ends use a two-seat design as standard, which means there is no need for a spring, which will extend the life of the part. A 24-hour salt spray test means that they can be trusted at all times, but to be sure we’ll also perform dynamic and elasticity tests as well. TRW tie rod assemblies are all adjustable to the needs of each individual chassis, and with a large selection, we’ll even provide a full OE standard repair kit to go with them.

Other products in the portfolio include:

  • Front and rear toe links – offering better straight-line stability
  • Centre links – ensuring an efficient, straightforward connection with the idler arm
  • Idler arm – providing pivoting support for the steering linkage
  • Pitman arm – converting the angular motion of the sector shaft to linear motion
  • Bellows – allows expansion and compression of a joint

The key to producing such market leading products is all in the intense testing process that we carry out on all of our steering linkage parts. Visual checks help us to assess quality variances where we examine physical performance for the following:

  • Break away torque
  • Rotational torque
  • Radial elasticity
  • Pull out force
  • Endurance test

TRW Track control arms

Choosing TRW Aftermarket is a simple and straightforward choice, with our control arm parts providing the following tangible benefits for drivers.

  • Improved fuel economy with optimised weight and shape through finite element techniques
  • Temperature resistant parts that perform in all conditions
  • More than 1,000 types of control arm components to choose from to cover all vehicle types
  • Enhanced ride handling and performance with a collection of rubber, metal and hydraulic bushes

With the most rigorous testing process employed across all of our parts you can be sure that TRW products are the best in the business.

A track control arm is the hinged suspension link that connects the chassis and the suspension that carries the wheel. Attached with a single pivot, normally a rubber bushing, the control arm can adjust the position of the outboard end while sustaining the radial distance from the inboard mount. A track control arm is one of the most mechanically impressive parts of the suspension system, which means it is important to replace them when they become worn or broken.

Often the reason a replacement is required is due to the ball joint or bushing being worn out, but it can be very difficult and expensive to replace these components separately. This is why TRW believes that replacing the whole part will be more efficient and provide a longer lasting fix. Drivers should also consider changing the control arm when the wheel has been damaged due to an accident.


Our selection of Upper and lower Track Control Arms features:

  • Aluminium forged Track Control Arms
  • Aluminium cast Track Control Arms – which are extremely low weight to ensure high performance levels
  • Steel forged Track Control Arms
  • Steel stamped Track Control Arms

Ball Joints also feature in our steering and suspension range of parts, which are crafted using state-of-the-art techniques to make sure that they deliver an exceptionally high performance. These parts are all temperature resistant so that they can perform in any conditions as well as offering low-torque and high comfort solutions. With a range from 25mm to 42mm, and with integral as well as non-integral designs, TRW caters for every vehicle type. TRW also produces a mixture of rubber, rubber and metal and hydraulic bushes as part of the range.

TRW stabiliser links

A stabiliser link performs a crucial role in the performance of any vehicle, connecting other parts of the suspension set up that absorb the shocks from potholes or bumps in the road. Therefore stabiliser links or stabiliser bars need to be performing at their best to guarantee driver safety and comfort.

TRW stabiliser link offers
TRW stabiliser-link

The replacement of a faulty stabiliser link with a new TRW stabiliser link on a car has an immediate, easy to identify effect on the quality of driving. The benefits of a TRW stabiliser link are:

  • Improved fuel economy
  • Lower emissions
  • Enhanced driving comfort and support

With years of experience in the aftermarket, TRW can supply high-quality, efficiently produced parts that make a real difference to driver safety on the road.
