MOOG RK643074 for Ram 1500
This MOOG front left upper control arm and ball joint assembly is best for owners of listed Ram 1500 applications who want the ball joint included with the arm. The stated fitment covers 2011–2018 Ram 1500, 2019–2020 Ram 1500 Classic, and 2009–2010 Dodge Ram 1500.
MOOG describes the arm as designed to support suspension geometry, wheel alignment, and stable handling. Its durable construction is intended for road stress and everyday driving. These features make it a relevant replacement candidate when the existing driver-side upper arm needs service.
Limitation: The fitment list includes specific model years and Ram versions. Verify the exact vehicle before purchase rather than relying on the Ram 1500 name alone.
MOOG RK80306 for Ford F-150
Choose this MOOG assembly if you need a front left upper control arm for a listed Ford F-150 application. The supplied fitment includes F-150 model years from 2004 through 2014, with year ranges specified in the product listing. It also lists 2007–2017 Ford Expedition and 2006–2008 Lincoln Mark LT.
The assembly includes a ball joint. MOOG says its control arms are designed to help maintain proper wheel alignment and stable handling, with construction intended to withstand normal road stress. It is best for buyers prioritizing a listed vehicle-specific assembly rather than a bare control arm.
Limitation: The year ranges vary by model, and the listing does not establish fitment for every trim or configuration. Check exact application details before ordering.
MOOG RK623125 for Newer GM Models
This MOOG front left upper arm is best for buyers whose vehicle appears on its GM fitment list. Applications include 2014–2018 Chevrolet Silverado 1500, 2019 Silverado 1500 LD, 2015–2020 Chevrolet Tahoe and Suburban, 2015–2020 Cadillac Escalade models, and 2015–2020 GMC Yukon models.
The product combines the control arm and ball joint. MOOG states that the component supports suspension geometry and stable handling, and is built to handle everyday road stress. Its broad listed coverage makes it a useful option to compare for compatible GM trucks and SUVs.
Limitation: The listing separates certain model years and vehicle versions. Confirm that the exact model and year are included before selecting this assembly.
Youxmoto Left Arm for Older GM Vehicles
This Youxmoto control arm is best for owners of listed 2007–2014 GM trucks and SUVs seeking a front upper left driver-side part. The fitment list includes select Chevrolet Silverado 1500, Avalanche, Suburban, and Tahoe models, along with GMC Sierra 1500, Yukon, and Yukon XL, plus Cadillac Escalade variants.
Unlike the MOOG items above, the provided features emphasize vehicle coverage rather than construction or handling claims. Use the detailed model-year list to assess whether this part is a match for an older GM application.
Limitation: Some 2014–2017 fitment entries apply only to vehicles with forged steel arms. Check the arm type on the vehicle and match it to the listing before ordering.
A-Premium Left Arm for GM Vehicles
A-Premium is best for buyers checking fitment on select 2014–2020 Chevrolet, GMC, and Cadillac vehicles. The listed component is a front upper left driver-side arm made of steel, with a ball joint and bushing included. It is described as pre-greased and supplied with original dimensions for installation.
Its application list covers certain Silverado, Sierra, Suburban, Tahoe, Yukon, and Escalade models. The product details also call out stamped-steel-arm requirements for some 2014–2016 applications and aluminum steering knuckles for specified vehicles.
Limitation: Fitment depends on configuration, including arm type and steering knuckle. Compare those details with the vehicle before buying.
Buying Guide: How to Choose a Left Upper Control Arm
How do you confirm fitment?
Start with the vehicle’s year, make, and model, then check the product’s full application list. Also verify the driver-side position and any configuration notes, such as stamped steel or forged steel arms, or aluminum steering knuckles. Similar model names do not guarantee that the same part fits every version.
Should you choose an assembly with a ball joint?
Several options here include a ball joint, and A-Premium also lists a bushing. An assembly may suit buyers seeking the listed components together. Check what is included and compare it with the repair need; do not assume every control arm listing includes the same parts.
How should you compare brands and applications?
Use fitment first, then compare the stated features. MOOG highlights suspension geometry, alignment support, and durable construction. Youxmoto’s provided details focus on its GM vehicle coverage, while A-Premium specifies material and included components. These descriptions are not a substitute for verifying application.
What should you check before installation?
Confirm the replacement is for the front left, or driver side, and matches the existing setup. If fitment remains uncertain, consult a qualified parts supplier or mechanic using the vehicle identification number and suspension details. Follow appropriate service procedures for suspension work.
Frequently Asked Questions
What does a left upper control arm do?
It is a suspension component that connects parts of the wheel assembly to the vehicle and helps maintain suspension geometry. The listed MOOG products specifically describe support for wheel alignment and stable handling.
Is the left side the driver side?
For these product listings, left-side placement is identified as the driver side. Confirm the product’s stated installation position before purchase.
Do these products fit every trim of the listed vehicle?
Not necessarily. Several listings include configuration-specific notes, and a model name alone may not confirm fitment. Check the full year and configuration details.
Does every control arm include a ball joint?
No. The MOOG assemblies and A-Premium listing specify a ball joint. Review each product’s included-component details before choosing.
