Description
CASE: Our Nodular Iron center sections will give you the perfect foundation for a high-quality, bulletproof rear differential, with a through bolt design and extra material is added to the bearing caps. These cases are offered in 3.062" & 3.250" bearing diameter to accommodate 28, 31, and 35-spline carriers and spools.
The lightweight SPOOL gives you the traction you need by locking the axle shafts together, forcing your rear tires to turn at the same speed. They"re CNC-machined from forged chromoly steel to provide a more rigid ring gear mounting. This eliminates gear failure caused by case deflection or differential side-gear failure.
The GEARSETS used are HI-PERFORMANCE 8620 Chrome-Nickel-Moly Steel. CNC machined from high-quality forgings to our exacting specifications and then heat-treated to obtain high impact and durability. Then lapped to allow for correct tooth contact and smoothness and for use in the performance market. The 8620 Gearset has proven itself in all forms of motorsport over the past 30 years.
YOKE: Speedmaster TDS Billet yokes are a long style unit fully CNC machined to our specifications.
NOTE: These 3rd members are to be used with a mineral-based oil of a range of EP140 Extreme pressure at a minimum, NO split grades eg. 85/140 (These are not recommended), failure to use the correct oil can result in gear damage, noise and may void your warranty.
