Laser-cut, CNC-bent 4130 chromoly replacement upper control arms with self-lubricating bushings and 1-ton spring-loaded ball joints, for added leveling-kit clearance and durability over the stock stamped-steel arms.

why this one — This is the one ReadyLift product found this session that spans BOTH the 2011-2014 GMT900 and 2015-2019 K2 HD chassis generations in a single SKU (2011-2019 fitment) - a real cross-generation part, unlike the leveling kits which are chassis-specific (2020-2026 T1 only).

why no number is shown

Suspension/control-arm upgrade, not a power-related part.
