UPPER CONTROL ARMS – WHAT ARE THEY?
The upper control arm is where the top of the suspension strut attaches to the car. It is a pivoting arm that goes up and down with the wheel. This helps with wheel clearance for larger tyres while also correcting the steering geometry of the wheels with a greater level of adjustment and accurate alignment.
With 2 inches of lift, on factory UCAs, we often find that we run out of adjustment to achieve the correct alignment for the camber and caster. This can then result in driveline vibrations, premature wear of vehicle components, and very likely excessive wear on tyres!
DO YOU REALLY NEED THEM?
Just think about how much your top quality, larger all-terrain or mud-terrain tyres cost you. The last thing you want is to be changing the fronts every 20,000kms, right?
This is where good quality aftermarket upper control arms come in…
