Overview

The Rock Krawler 4.5" X-Factor Pro Elite Coilover Mid-Arm System is designed for Sport/Overland owners seeking a complete bolt-in system with excellent articulation. It features PB+J (Pure Beef and Jealousy) mid-arms machined from 2" x 3" billet 7075 Aluminum for lower control arms, and all other four control arms machined from round 7075 Aluminum with X-Factor built-in. The system offers 95 degrees of misalignment with Pro-X Krawler Joints and Adventure Series joints, reducing factory control arm bind. Maintenance-free Adventure Series joints are used at the frame connection, while PRO Krawler Joints are at the axle connections, allowing for precise tuning of caster and pinion angles. Gen 2 front sway bar disconnects maximize axle travel. Front and rear track bar geometry corrections ensure centered axles and uncompromised on-road handling. The system provides excellent highway ride and handling, improved rear roll center, 14.44 inches of front axle travel, and up to 15 inches of rear axle travel. It is upgradable to an RK Long-Arm System and includes a lifetime warranty.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
