What power and torque will it hold?
Typical rating is around 400 HP and ~800 lb-ft with towing up to ~15,000 lb GCW when set up correctly. For more headroom, consider HD organic or OFE variants.
Will it work with the OEM dual-mass flywheel?
No. Conversion kits like this require the South Bend solid mass flywheel for the ZF-5.
Is pedal feel close to stock?
Yes—full organic facings provide smooth, predictable take-up and daily-driver manners compared to more aggressive materials.
What if I tow heavy or plan to add more power?
Choose the F/C 1944-5OK-HD or F/C 1944-5OFEK kits for additional clamp load and heat capacity.
