Superior Engineering uses 35mm 4140 High tensile steel for their steering rods, other manufactures use as small as 30mm steel (figure 1).
Superior Engineering's "comp Spec" rods use heavy duty female tie rod ends as opposed to the factory tie rod ends which screw into the bar, the cheaper and smaller male threaded tie rod ends can bend when pushed hard. The heavy duty female ends also use a clamping system to hold them in place rather
than a lock nut.
All Superior Engineering's 4140 Comp Spec rods are CNC machined to ensure accuracy in the thread, and then they are zinc plated to increase resistance to corrosion.
When you buy a Superior Engineering solid bar drag link or Tie Rod you receive everything you need to fit it to your car.
We supply a bolt on steering damper bracket to suit your particular model, we believe if it is a required item it should be included in the price, NOT as an optional extra!
Don’t get bitten by lower quality products on the market
Go with a Superior Comp Spec rod and steer with confidence.
