10-Pack Stroked Overdrive Drum for Ford 6R140 – Warren Diesel Shop
The stroked 10-pack overdrive drum is a precision-modified OEM Ford component designed for extreme-performance 6R140 transmissions in 2011-2019 6.7L Powerstroke trucks. To accommodate 10 high-energy clutches (vs. stock 7), the drum is carefully disassembled, shimmed for additional clearance, and the halves are TIG-welded back together with expert craftsmanship for perfect alignment and strength.
This modification dramatically increases holding power in the critical 4-5-6 (overdrive) clutch pack, eliminating shift flare, reducing heat, and supporting 800+ RWHP builds for competition, heavy towing, or aggressive street use.

Practical Stall Speed Guidelines for the 6R140 (6.7 PowerStroke)
| Turbo Setup | Recommended Stall Range | Reasoning |
|---|---|---|
| Stock GT37 VGT | 1800 RPM | Extremely responsive; low stall = max efficiency |
| 63–67mm single | 1800 RPM | Still quick to spool; low/stock stall ideal |
| 67–76mm single | 1800 RPM | Slight bump acceptable; 2,000 is overkill |
| 80mm+ single | 2000 RPM | Larger lag; elevated stall needed to help spool |
| Compound/add-a-turbo | 1800 RPM | Big atmosphere turbo needs RPM to energize |
