Why upgrade the 2500HD's upper control arms
Heavy trucks eat front-end parts, and the 11-19 GM 2500HD's factory arms are the first to complain once the truck is lifted or run loaded off pavement. These replacement uppers pair Moog Problem Solver ball joints on the outer pivot with fully sealed inner pivot assemblies running 3/4-inch FK uniballs and 17-4 stainless misalignment spacers — a smooth, quiet setup built around the loads an 8,000-pound truck actually generates. Track width stays stock, and the arms allow more droop than factory (ultimately limited by OEM-replacement shock length).
Installation
The arms arrive as ready-to-install assemblies and bolt on reusing the factory UCA bolts — no cutting, no welding. Budget an alignment after install.
Common Questions
Which trucks do these arms fit?
2011-2019 Chevy Silverado and GMC Sierra 2500HD. A separate version covers the 99-10 trucks, and full 2500HD race kits are available for both generations.
Why Moog ball joints instead of a uniball on the outer pivot?
On a heavy tow-and-chase truck the Moog Problem Solver joint gives sealed, greaseable durability at the loads the outer pivot sees, while the sealed FK uniball inner pivots handle misalignment. It is the right combination for how HD trucks get used.
Do they change track width?
No — stock track width, with more usable droop than the factory arms allow.
