Revolution Gear & Axle REV-JK-NON-456-K 4.56 Ratio Gear Pkg 07-18 Jeep Wranger

Vehicle Fitment

• 2007-2018 Jeep Wrangler JK Non-Rubicon (all trims, 4WD) - Dana 30 front & Dana 44 rear differentials

Features

• 4.56:1 gear ratio engineered for enhanced low-end torque, improved off-road performance and compatibility with larger tires
• Comprehensive gear package covering front (Dana 30) and rear (Dana 44) ring & pinion sets for the JK Non-Rubicon
• Includes master install bearing kits (Koyo bearings) for both front and rear differentials - simplifying rebuild process
• Manufactured from premium 8620 alloy steel and heat-treated to OEM-style durability standards
• Precision-lapped gears for smooth engagement, reduced noise and long service life
• Optimised for lifted JK builds, heavy-load use and off-road applications where factory gearing is insufficient
• Backed by a 2-year limited manufacturer warranty against defects
• Front carrier required when upgrading from factory 3.21 ratio (Dana 30) only - ensures correct setup in such cases

Product Description

The Revolution Gear & Axle REV-JK-NON-456-K gear package is built specifically for the 2007-18 Jeep Wrangler JK Non-Rubicon models with Dana 30 front and Dana 44 rear differentials. With a 4.56:1 ratio, this kit offers a strong balance between off-road capability and on-road usability, making it ideal for larger tire setups, lifted suspensions or heavy-load use where the stock gearing no longer performs optimally.

Constructed from high-grade 8620 alloy steel, heat-treated for strength and longevity, and precision-lapped for smooth operation, the gear set also includes high-quality Koyo bearings and full master install kits for both axles. This makes it a true front-and-rear rebuild solution rather than just a ring & pinion swap - reducing the number of parts to locate and improving installation consistency.

Installation should be performed by a qualified technician using proper differential-setup tools: bearing preload, backlash and gear pattern must be correctly set to achieve optimal performance and longevity. Fitment is confirmed for the years listed above; coverage for other models or years beyond 2018 is unconfirmed at time of listing.
