Why upgrade the 19+ Silverado's upper control arms
The factory stamped arm and sealed ball joint on 2019+ Chevy and GMC 1500s are the weak links once the truck is lifted or driven hard. These arms replace them with a 1.25-inch FK uniball in a fully sealed outer pivot — our proprietary rubber boot and aluminum cover cap keep the grit out — plus fully sealed 3/4-inch FK uniball inner pivots with 17-4 stainless misalignment spacers. Race-truck bearing hardware, sealed so it stays quiet on the street.
Installation
Completely bolt-on: the arms reuse the factory UCA bolts and install with hand tools — no cutting, no welding. They run at stock height or lifted, with factory or aftermarket coilovers, and year/arm-style-specific 17-4 stainless misalignments are included. Get an alignment after install.
Common Questions
Do these uniball arms squeak?
No — the outer FK uniball is fully sealed behind a rubber boot and aluminum cover cap, and the inner pivots are sealed assemblies. Uniball strength with factory-arm quiet.
Which trucks do they fit?
2019-and-up Chevy Silverado and GMC Sierra 1500. They work at stock height or lifted, with factory or aftermarket coilovers.
Are they serviceable?
Yes — when the FK uniball eventually wears you press in a new bearing, unlike the factory sealed ball joint that forces a whole-arm replacement.
