Rock Krawler RK08346 Adventure X Pro Lower Long Control Arm PB&J

The Rock Krawler RK08346 Adventure X Pro Lower Long Control Arm is a premium, service-free suspension component built for off-road enthusiasts who demand the best in strength and durability. Part of Rock Krawler's legendary PB&J (Pure Beef and Jealousy) lineup, this long arm is CNC machined from billet aluminum for an unbeatable combination of lightweight construction and maximum toughness.

Key Features:

• CNC machined billet aluminum construction — provides exceptional strength while reducing unsprung weight
• 100% service-free design — no greasing required, eliminating routine joint maintenance
• Adventure Series joint at the frame-side connection — features OEM-style vulcanized rubber compression molded over a precision machined housing with service-free Garlock Bearings and a polished nitride-coated pivot sleeve
• High misalignment capability — Adventure Series joint provides up to 35 degrees of misalignment at the frame end; total misalignment up to 70–95 degrees depending on axle-end joint configuration
• Long arm length — improves suspension geometry, caster correction, and overall articulation compared to stock or mid-arm configurations
• High-clearance formed design — bent profile adds critical ground clearance for rock crawling and trail use
• Adjustable length — allows precise pinion angle and caster tuning for optimal on-road and off-road performance
• Durable black powder coat finish for corrosion resistance

Rock Krawler's Adventure X Pro lower long arms are engineered to bridge the gap between a comfortable daily driver and a hardcore trail rig. The long arm geometry significantly improves suspension travel and axle articulation, while the service-free joint design means less time wrenching and more time on the trail. A professional alignment is recommended following installation.
