In our full competition builds, safety is always at the forefront. One of the biggest upgrades to this kit is the addition of our Ultimate Weapon Billet Direct Drum. This billet direct drum is made from 4140 billet steel; this is to ensure the utmost safety when you consider the direct drum is traveling 2.2 times the speed of the engine. As you can imagine, when things let go at that speed, the results are catastrophic, and we've all heard the stories of severed limbs with transmission failures. This drum also maintains conformity at higher RPMs, reducing deflection when the band is applied. This combination has proven to dramatically reduce shift times. In addition to the safety features, this drum has an extended snap ring groove to allow the inclusion of more clutches. This is matched perfectly with the extended height of our 27 spline input shaft and hub, also included in this kit.

We also replace the factory intermediate shaft with a billet one. Designed for high torque & heavy towing applications, the shaft is precision machined and ground from 300 Maraging steel (VASCOMAX) and heat treated for superior surface toughness and durability. It is made for high torque engines and is an ideal replacement part to satisfy the demands for extreme off-road service and high performance applications. The intermediate shaft is spline-machined with large blended radius to reduce common fractures associated with the OEM design.

Lastly, we include a billet output shaft. Designed for higher horsepower/torque engines, this performance product has been tested in excess of 1,400 ft/lbs of torque. Shaft is machined from 300M material then Heat Treated for torsional strength and precision ground on all critical diameters.
