Keep hardworking trucks on the road with this Sonnax Smart-Tech Overdrive Housing Kit. The unique billet aluminum housing holds a physically taller clutch pack and increases OD apply area by 16%. Plus, 2X thicker clutches increase clutch pack steel mass by 28% for unrivaled heat dissipation.
This groundbreaking kit is the only top of the line upgrade that eliminates clutch problems without relying on valve body/pump modifications or adding the expense of extra components.
- Modified housing holds physically larger clutch pack for 20% more clutch capacity
- 2X thicker steels and double sided clutch pack increase steel mass by 28% for unrivaled heat dissipation
- Bolt-on anchor plate eliminates clutch pack flexing and distortion that contributes to heat build up
- 16% more OD apply area for firmer, more controlled shifts
- Combine with Sonnax Line Pressure Booster Kit RFE-LB1 for even higher levels of performance
- UnderDrive Piston
- Low/Reverse Piston
- UnderDrive Balance Piston Retainer
- 4th Clutch Piston
- 2nd Clutch Piston
When diesel trucks are modified for either racing or street use, OE clutch plates slip and just do not hold. Limited damper capacity further cripples performance.
Upgrading to an aftermarket multi-plate converter is the only solution.
Enhanced design features include:
- Fully-machined, forged piston and custom damper rivets won’t bend under extreme lockup pressure.
- Piston is tested and proven to withstand bending up to 400 psi.
- Spring end caps limit how far springs compress under load to prevent breakage.
- Increased oil flow improves cooling and lubrication of clutch plates.
- Patented piston/damper assembly absorbs up to 1,250 ft-lbs. of torque. That’s nearly twice the stock capacity of the 68RFE.
- Three solid, non-segmented, high-thermal, high-torque capacity friction elements.
