Detailed Description

Moog RK100217 is engineered for the front upper position on 2007-2017 Jeep Wrangler and 2018 Jeep Wrangler JK models. The adjustable design allows plus or minus 3 degrees of caster and plus or minus 3 degrees of pinion angle, making it a practical choice when suspension changes, lift kits, or alignment correction are part of the repair. The forged steel body adds strength, while the rubber bushings help maintain controlled suspension movement and ride quality. If you are replacing a worn Jeep Wrangler front upper control arm, RK100217 provides a precise OE replacement path with the fitment and geometry needed for proper suspension setup. This part cross-references Mevotech Supreme CMS251207 for the same application.

Common Problems It Can Address

• Excessive front-end play from worn control arm bushings
• Alignment issues after suspension lift or geometry changes
• Clunking or knocking from a damaged upper control arm
• Uneven tire wear caused by incorrect caster settings
• Pinion angle correction needs on Jeep Wrangler suspension setups
