Upgraded precision components. The new Weddle HV2 gearboxes feature upgraded internal components for improved shift performance including:

• Stronger and stiffer billet shift forks
• Heat treated and precision ground shift rails and shift shafts
• Bronze shift rail guides
• Hardened and ground steel shift gates
• Improved HV2 shift rod, ball and cup

Centrally positioned shift rod. We relocated the shift rod on the new HV2 gearboxes within 1.75 inches of the centerline. This enables a simple, direct and efficient linkage from the shifter to the gearbox.

Mid engine ready. We left the original offset shift shaft on the side of the HV2s for use in mid-mount applications. A specially designed shifter and bolt-on linkage are available. 

Internalized ball/cup. We relocated the ball/cup mechanism from the external adapter of the HV1 to inside the main case in the new HV2s. This allows the ball/cup to remain lubricated and grime free.

Other Weddle HV2 features include:

• 27mm wide forward gears - all gears ground after heat treat
• Torsional 300M input shaft
• Mid-plate bearing support between 2nd and 3rd gears
• Tapered roller bearings on mainshaft to handle end thrust
• Heavy duty synchronized reverse gears
• Weddle Racing 10" Klingelnberg Palloid ring & pinion
• Optional 934 flanges
• Chevy bell housing option
• Internal oil pump option
