Sonnax Big Input Shaft Kit

The Sonnax Smart-Tech big input shaft kit 22121B-08K is the ultimate solution to prevent input shaft spline-twist and breakage in high torque Chrysler 47RH, 47RE and 48RE diesel applications. Compared to the best 300M 23-spline shafts, the Sonnax input shaft is 35% stronger at both the spline portion of the shaft and the sealing ring/cross-hole area of the shaft, eliminating all concerns of failure at these critical points.

The larger sealing ring and cross-hole area requires a custom stator/pump cover assembly. The stator assembly features standard 48RE tube splines made of high-strength steel, improved retention in stator body, 48RE matched pump porting and special rubber seals to eliminate oil leakage between cover and pump body.

The longer direct (front) clutch hub portion of the shaft has longer splines that allows for one extra (OE-thickness) direct friction plate when used with included thinner billet aluminum direct piston, all while keeping OE-thickness steels, backing plate, OE waved retaining ring and OE clutch clearances.

Some common aftermarket modifications designed to include extra clutches require reduced steel thickness and decrease the heat absorption capacity of the clutch pack, others reduce clearance and eliminate the waved retaining ring, which contributes to excess 2-3 shift overlap. The Sonnax kit avoids these problems by increasing the number of frictions from five to six, adding to the steel mass of the clutch pack and maintaining the OE thickness backing plate and clearances for the optimum combination of increased capacity and durability.

  • Extreme duty, 1-1/8” diameter 35-spline input shaft
  • .100” larger diameter at sealing ring cross hole area
  • One-piece shaft forged from ultra-high strength 300M billet steel eliminates weak connection between shaft and clutch hub
  • Keeps OE oil flow areas and eliminates leakage for predictable, trouble-free lockup, release and apply
  • Custom stator assembly optimizes performance and long-term durability
