When it comes to modifying your truck, upper control arms (UCAs) are a well-known upgrade for lifted applications. But now, they’re becoming essential for lowered trucks—especially on newer platforms like the 2019+ GM 1500 Silverado & Sierra.
So why are upper control arms needed on lowered trucks? Do they actually improve performance, or are they just another add-on? Let’s break it down.
Why Lowered Trucks Need Upper Control Arms
With every new truck generation from Chevy, GMC, Ford, Toyota and Ram, suspension design continues to evolve. Engineers are constantly improving fuel efficiency, ride quality, handling, and payload capacity—but these changes also impact how aftermarket modifications perform.
One major change in modern trucks is how the front suspension geometry works.
At ride height, suspension movement is divided into:
- Bump travel (upward movement)
- Droop travel (downward movement)
Older trucks followed a predictable camber curve. As the suspension cycled up or down, camber gradually became more negative in a consistent way.
However, more recent suspension designs, (such as with the 2019+ GM 1500 trucks) behave differently.
During bump travel, the suspension quickly moves into extreme negative camber, while droop travel remains relatively stable. This creates a problem when lowering your truck.
The Problem: Camber Issues on Lowered Silverado & Sierra 1500 Trucks
When you lower the front of a 2019+ Silverado & Sierra 1500 more than 1 inch using our adjustable lowering struts, the factory suspension geometry no longer allows for proper alignment.
This can lead to:
- Uneven tire wear
- Poor handling performance
- Reduced suspension longevity
Without correction, your truck may not align back to factory specifications.
The Solution: Max Trac Part# 351900 Upper Control Arms
To solve this issue, Max Trac Suspension is introducing part# 351900 Upper Control Arms, specifically designed for lowered 2019+ GM 1500 trucks.
These forged aluminum upper control arms are engineered to correct camber and restore proper suspension geometry—while also improving durability and performance.
Key Features:
- Camber correction for lowered trucks
- Extended arm length for proper alignment geometry
- Improved ball joint angle for better suspension travel
- +3 degrees of positive camber adjustment
- Helps bring alignment back to factory specifications
Available as a Complete Lowering Solution
The Max Trac 351900 UCAs will be available:
- As a standalone upgrade
- Or included in our 2”/4” (w/ struts) and 4”/6” lowering kits for GM 1500 trucks
This makes them an ideal solution whether you’re upgrading an existing setup or building a complete lowering kit.
Coming Soon from Max Trac Suspension
At Max Trac Suspension, we continue to develop high-quality, affordable suspension components for both lifted and lowered trucks.
Our new part# 351900 Upper Control Arms for 2019+ GM 1500 trucks are the latest addition to our growing lineup of forged suspension products—with more innovations coming soon.
