TeraFlex 3209430 Tera CRD60 HD Rear Full-Float Coilover Axle Assembly 4.30 R&P JL

The TeraFlex Tera CRD60 HD Rear Coilover Full-Float Axle Assembly (Part #3209430) is a complete, ready-to-install rear axle solution engineered specifically for use with a TeraFlex Coilover Suspension System. This variant comes pre-configured with a 4.30 ring & pinion gear ratio, a pre-installed ARB air locker, full-float outer axle shafts, inner axle shafts, and all necessary sensors for a seamless installation.

Built around TeraFlex's exclusive Constant Radius Design (CRD), this 70" wide axle housing maintains maximum ground clearance regardless of pinion angle adjustments—a critical advantage when navigating rocky trails and extreme terrain. The assembly is engineered to integrate directly with TeraFlex JL Coilover Kits, featuring integrated Coilover Mount Brackets, bump-stop strike pads, high-clearance lower control arm brackets, and reinforced upper control arm mounts capable of handling the increased loads and articulation of a TeraFlex/Falcon Coilover Suspension System.

Key Features:

• 70" WMS-WMS width with 8x6.5" wheel bolt pattern
• Constant Radius Design (CRD) for high ground clearance unaffected by pinion angle changes
• Integrated Coilover Mount Brackets for direct bolt-on compatibility with TeraFlex/Falcon Coilover systems
• Full-float axle design with 35-spline inner and outer axle shafts
• Pre-installed 4.30 Super 60 ring & pinion gears and ARB air locker
• Includes 1350 series pinion yoke
• HD bearing caps increase rigidity and reduce ring & pinion distortion
• Built-in oil skimmer cuts ring gear oil halo and forces it into pinion bearings
• Outer pinion bearing pocket with renewable oil reservoir for continuous bearing lubrication
• Oversized outer pinion bearing for increased torque and high-load conditions
• High-capacity housing with high-flow oil passages and bottom drain hole
• Ductile cast iron housing with increased rib gussets
• HD ductile iron differential cover with increased cover mounting area
• Integrated lower control arm skid plates
• Bump-stop strike pads and reinforced upper control arm mounts
• Pre-installed inner axle seals and upper control arm bushings
• Designed for 0–6" lift applications

This axle is a true bolt-on solution for JL Wrangler and Unlimited models—including Rubicon editions—eliminating the fabrication and guesswork typically associated with axle upgrades when paired with a TeraFlex Coilover Suspension System.
