Longfield Chromoly Front Axle Kit 33-Spline / 22-Spline – Suzuki Samurai & Jimny JB31

Eliminate one of the most common weak points in Suzuki Samurai and Jimny front axles with the Longfield Chromoly Front Axle Kit (33-Spline / 22-Spline), designed for Suzuki Samurai (1986–1995) and Suzuki Jimny JB31 (1993–1995).

SKU: 304095-3-KIT

Factory front axles are known to fail when running larger tyres, front lockers, or tackling demanding off-road terrain. This upgraded kit solves that problem by combining 22-spline differential-side shafts (for direct fitment into stock differentials) with a 33-spline Birfield design that improves torque distribution and significantly increases strength.

Built from high-strength chromoly steel and engineered for extreme use, this kit is ideal for serious off-road builds, rock crawling setups, and anyone looking to future-proof their drivetrain.

Key Features

• Heavy-duty chromoly front axle upgrade
• 22-spline diff-side fitment – installs into stock differentials
• 33-spline Birfield design – improved strength and torque handling
• Approx. 21% stronger than OEM axles
• Dual heat-treated components for durability
• Designed for larger tyres, lockers, and aggressive off-road use

Vehicle Compatibility

• Suzuki Samurai (1986–1995)
• Suzuki Jimny JB31 (1993–1995)
