How will this control arm affect steering and alignment?

Replacing a worn upper control arm like the RK622128 helps restore proper suspension geometry, which improves wheel alignment and steering precision. That regained alignment reduces unpredictable steering pull, minimizes uneven tire wear, and returns a more direct steering feel.

• Pre-assembled ball joint for correct pivot point and fit
• Maintains factory suspension geometry for accurate toe and camber
• Reduces steering wander and compensates for worn arm-induced play

What makes this MOOG assembly durable for heavy-duty use?

MOOG designs this control arm with reinforced materials and a protective coating to resist corrosion and endure road impacts common to heavy-duty trucks. The assembly’s components are selected and assembled to handle the extra loads from towing, hauling, and off-road exposure without premature failure.

• Robust construction to withstand daily and heavy-duty driving stresses
• Corrosion-resistant finish extends service life in wet and salty conditions
• Precision-assembled components to reduce early wear under load

Is installation straightforward for a DIYer or technician?

The RK622128 arrives as a pre-assembled control arm and ball joint, which shortens installation time versus separate components. Basic suspension tools and a torque wrench are required; alignment is recommended after installation to ensure correct handling and tire wear.

• Pre-assembled unit reduces assembly steps at installation
• Fits directly to factory mounting points on specified GM HD models
• Post-install wheel alignment advised to maintain optimal handling

Which vehicles and model years does this part fit?

This control arm is manufactured to fit specific heavy-duty GM pickups from the 2011 through 2019 model years. Confirm fitment with your VIN or vehicle application guide before purchasing to ensure a correct match.
