Your Diesel’s Power Is Limited By The Factory Transmission
Have a strong truck and need it to do what you bought it for? Then you want a diesel enthusiast — not just anyone — involved in your next build or upgrade.
At Sun West you can speak with the owner directly and go over your usage needs and goals. We build custom 68RFE transmissions for Ram 2500, 3500, 4500 and 5500 trucks.
Heavy-Duty 68RFE Builds In Glendale
No heavy-duty diesel is complete without a strong, reliable transmission. Whether your 68RFE is nearing the end of its service life or you are planning upgrades for more payload and performance, Sun West Transmissions is your choice for HD transmission builds. We have served Glendale and Phoenix since 1979.
Our rebuilders go beyond the usual repair process to give you a 68RFE that can take punishment — a transmission better than a factory-built unit. Our rebuilds exceed OEM specifications, and we correct every known factory defect, plus more depending on how you use your truck.
Recommended 68RFE Upgrades
LuK By Schaeffler TorCon Quad-Disc Converter
The LuK TorCon TC0011 is built with all-new components for consistent performance and is designed specifically for the diesel 68RFE. Where the factory converter uses a dual-plate lockup clutch, the TC0011 uses a quad-plate clutch with more torque capacity than even some triple-plate billet converters. Inside are LuK friction material, INA thrust bearings and fully furnace-brazed fins for long-lasting durability.
We also build billet torque converters to your needs, with or without extra clutches.
Billet Overdrive Clutch Housing Kit
Adding power and pulling heavy loads puts the overdrive clutch at high risk of burning up. The stock clutches are thin (.034-inch, single-sided), and even small amounts of extra heat and torque can distort the clutch pack and make overdrive failure inevitable. The billet OD clutch housing fixes that:
- Billet aluminum shell holds a larger clutch pack for 20% more clutch capacity.
- Steel plates twice as thick as stock and double-sided — 28% more steel mass for better heat dissipation.
- Bolt-on anchor plate eliminates clutch-pack flexing and distortion.
- 16% more overdrive apply area for firmer, more controlled shifts.
Part No. 72960-16K replaces OE part number 68029262A and fits Chrysler, Dodge and Jeep 45RFE, 545RFE, 65RFE, 66RFE and 68RFE transmissions.
