Question uca question

what exactly is the major difference between a tc uca and the stock one. I dont really understand why they need to be changed when a truck is lifted.

From totalchaos
When aftermarket lifts are installed on these model vehicles the OEM suspension design looses caster. By altering the factory caster, the vehicle will lose on road handling & performance and has a tendency to wander when driving down the road. TC developed the UCAs to add caster to the suspension when aftermarket coil over shocks and other lifts are installed. This will increases overall handling and aids in the alignment of the vehicle.

The Light Racing arms are the closest you'll find to that solution. They use a stock-style joint rather than a uniball where they mount to the top of the spindle.

The stock ones are stamped steel. If you're gonna modify them yourself, you're better off starting from scratch and designing something from the ground up as it'll be faster to develop and the end product can be far stronger than what came from the factory.
