About G2 Axle & Gear
For serious off-road enthusiasts and 4x4 builders, few names carry as much weight as G2 Axle & Gear. Rooted in the belief that stock drivetrain components simply aren't built to keep pace with today's lifted, tire-stacked, high-output 4x4 builds, G2 set out to engineer aftermarket solutions that meet — and routinely exceed — OEM specifications. The result is a product lineup that has earned a loyal following among Jeep, Toyota, and GM off-road enthusiasts alike.
Precision-Engineered Drivetrain Components
G2's reputation was built on its differential ring and pinion sets. The company's Performance Series gears are forged from 8620 steel, precision-machined to tight OE tolerances, heat-treated for durability, and lap-finished to minimize friction and noise — a level of refinement that makes installation straightforward and long-term reliability exceptional. Whether you're re-gearing for larger tires or chasing maximum torque multiplication on the trail, G2 ring and pinions cover a broad range of axle families and gear ratios.
Complementing the gearing upgrades are G2's axle shafts, which are forged from high-tensile alloy steels and heat-treated for maximum strength. Available in upgraded spline counts, they are designed to handle the increased loads that come with larger tires and aggressive trail use — replacing the factory shafts that are often the first weak link in a modified drivetrain.
Protection and Performance for Your Differential
G2 also produces a well-regarded lineup of differential covers in both high-strength, heat-treated aluminum and super-strong nodular iron. The aluminum covers are engineered to help cool gear oil for prolonged bearing life, while the nodular iron versions are built to absorb direct hits on the most demanding terrain. Both styles add a layer of protection that stock stamped-steel covers simply can't match.
Suspension and Air System Accessories
G2's expertise extends beyond the differential itself. Their suspension track bar brackets are constructed from heavy-duty steel and designed to maintain the factory track bar mounting location — an important detail when adding axle truss systems or reinforcing the front end of a Jeep for high-clearance builds. For wheelers running G2's pneumatic locker and CORE DRS Sway Bar systems, the brand's shop air compressor provides the compact, reliable on-board air supply needed to activate up to four solenoid-controlled devices, complete with a sealed, maintenance-free assembly and a universal mounting bracket.
Built for Those Who Push Harder
Every G2 product is manufactured with hardcore users in mind. The brand's commitment to precision, strength, and quality means that whether you're a weekend warrior tackling rock crawls or a daily driver pulling heavy loads, G2 Axle & Gear provides the confidence that your drivetrain can keep up.
