A limited slip differential with exceptional strength and durability designed to launch harder and corner faster

Rialto, CA (November 1, 2023) — Speedmaster®, a leading global automotive performance brand, is gearing up to introduce yet another trailblazing product at the 2023 SEMA Show – the DANA 30, 27 Spline Torque Worm Helical Gear Limited Slip Differential is a torque biasing 6 pinion gear type limited slip unit.

The Speedmaster Torque Worm LSD addresses some of the most common challenges faced by traditional differentials by setting a new benchmark in durability, reliability, and performance to allow for harder launches and faster corners. 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.
Product Features Include:
• Unique 6-Pinion Gear Design: Breaking away from the industry norm of 3 or 4-pinion gears, Speedmaster’s 6 pinion gear arrangement significantly reduces stress on the internal components, providing an enhanced lifespan.
• High-Caliber Material Selection: Components crafted from premium EN36 Material, trusted in elite racing tiers like V8 SUPERCAR. An outer case built from 8620 Chrome-Nickel-Moly steel ensures exceptional strength and durability.
• Responsive Performance: As a preloaded unit, the TorqueWorm promises prompt responsiveness during torque shifts, ensuring impeccable traction and gear transitions, essential for high demand driving conditions.
As a part of Speedmaster’s ongoing commitment to pushing the boundaries of race performance, this innovative limited slip differential is among one of the latest entries for this year’s SEMA New Products Award competition. Offered at a MSRP of $500.50, this LSD blends both superior engineering and cost-efficiency.

To discover more about the DANA 30, 27 Spline TorqueWorm LSD, visit Speedmaster at one of two locations at the 2023 SEMA Show. Speedmaster’s inside booth is located at #22753 in Racing and Performance in Central Hall, and the outside location is booth #81020.
For more information, visit www.speedmaster79.com, email info@speedmaster.com, or call (909) 605-1123. For more information about Speedmaster, view this video.
