5.9L Cummins (1994-07) Torque Converter & Sonnax Extreme Duty Kit
**If you already own a Sonnax Extreme Duty "Big" Input Shaft Kit, you must call in to order the mating converter - you may ONLY purchase both the converter and shaft "as a kit" through this online listing** (563) 778-2719
Shaft Kit Includes:
Sonnax Smart-Tech® Big Input Shaft Kit with Goerend Lube Modification
Part No. 22121B-08K
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.
YOU MUST PURCHASE THE MATCHING 35 SPLINE GOEREND CONVERTER - DO NOT BE FOOLED, THIS INPUT SHAFT WILL NOT FIT A CONVERTER WITHOUT A 35 SPLINE TURBINE HUB!

The most versatile converter offered. It is loose enough to spool most turbos, in most elevations and climates, while maximizing low end grunt and keeping the torque converter tight enough when the turbo lights and horsepower is being made. This converter should go in trucks that TOW and WORK HARD. Approximately 200-400 RPM lower than a stock converter.
This converter works well with:
Stock turbos from 0-11,000 foot elevation
2nd generation dodges (0-4,000 foot elevation) with stock to 58mm turbos
3rd generation dodges (0-4,000 foot elevation) with stock to 62mm turbos
Used for light to heavy towing. This converter stall is equivalent to a stock converter stall.
This converter works well with:
2nd generation dodges with 60-62mm turbos at 0-4,000 foot elevation
3rd generation dodges with 63-71mm turbos
0-4,000 foot elevation with 67-71mm turbos
0-11,000 foot elevation on 63-66mm turbos
This converter will be approximately 300 RPM looser than stock. It is a higher stall to help get large turbos spooled. This stall is not recommended for towing.
TO SHIP TO ANY LOCATION OUTSIDE OF THE LOWER 48 STATES - PLEASE CALL FOR A QUOTE BEFORE PURCHASING. Fixed freight cost ONLY applies to UPS Ground Shipping. If you select anything other than ground freight on a converter order we will need to contact you to discuss availability & adjust freight amount. If you need a rush order, please call us to order!
