(700+ hp; 33.50-lb. case)
|
The Pro-Iron package is our assembled third member for performance applications
nearing or exceeding 700 horsepower. The assembly features a heavy-duty,
nodular-iron gear case with chromemoly caps. Pro-Iron cases are created
from D-4512 nodular iron, 8% stronger than nodular iron used in OEM cases.
Additional ribbing and increased material around bolt holes and bearing
bores create a virtually indestructible case suitable for any performance
application. Stud holes are spot-faced for even fastener-clamping force
and improved sealing. Chromemoly bearing caps are designed with increased
thickness for added strength and ring-gear stability. The case features a large 3.250”
bore for street/strip 35-spline axles. Standard
components include chromemoly yokes and forged aluminum pinion supports with 35-spline steel spool. Ring-and-pinion-gear
selections range from 3.40-4.86:1 and are professionally adjusted when
assembled.
