Whether you're assembling a daily driver, street rod, or race car, Speedamster's third member assemblies will provide the durability that your vehicle deserves. 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 TORQUEWORM is a torque biasing 6 pinion gear type limited-slip unit. This is a preloaded unit allowing for a faster-reacting unit. Unlike our competitors that only use 3 or 4 pinion gears. The use of 6 pinion gears means the stress on gears is spread over a greater surface area, reducing the load on all internal components. The internal components are made from EN36 Material as used in racing such as V8 SUPERCAR. The outer cases made from 8620 Chrome-Nickel-Moly steel and the case hardened for long life and improved strength. The GEARSETS used are HI-PERFORMANCE 8620 Chrome-Nickel-Moly Steel.
