Product Details

The ReadyLift 4" SST UCA is made for the 2019-2026 GMC Sierra 1500.

ReadyLIFT is excited to release SST Upper Control Arms(UCA), sold in pairs, as part of our ever-expanding suspension accessories. SST UCA " are designed for and compatible with most lifted trucks. ReadyLIFT UCA kits are the same arms included in our full SST Lift Kits; however, they are now available standalone for customers seeking to upgrade their lifted truck with superior UCAs. Upper Control Arms are a great addition to lifted trucks.

They provide improved suspension geometry for improved tire wear, increased stability, better handling, and exceptional road feel. Upper Control Arms are an integral part of independent front suspension (IFS) vehicles and generally connect the top of the knuckle to the frame. The UCA continually locates and guides the knuckle in a pre-determined path when the suspension cycles up and down during driving.

Features

  • DOM tube steel upper control arms
  • TCT Terrain Control Technology maintenance-free pivot bushings
  • HD ball joint for better durability
  • Designed for vehicles with ARC D suspension system
