I started the clutch thread on other forum.
I’ll like to make a quick update on LuK’s Cerametallic clutch kit (part# 05181) I used in my truck.
I emailed Schaeffler tech support on what it’s rated at, shockingly they replied quickly, said approximately 740 ft•lbs
almost 2 years now with ~15k miles with this clutch
This cerametallic clutch HATE to slip! More like grabby on/off when hot (stop and go traffic). I need to use the granny low despite when not towing to take off from a stop to keep it happy, not a huge deal. I also use 4low (front hubs unlocked) to maneuver the trailer without slipping the clutch. Towed at over 20,000 lbs GCW locally with no issue. Towed my 18’ car trailer with my XJ (roughly 6,500-7,000 GTW) up 10% grade at full power to grab 4th gear (and just cuz its fun) and the clutch did not slip whatsoever.
Truck info: 12v Cummins with the big stick cam, 17* timing, fuel plate deleted, AFC LIVE tuner, nv4500, 4x4, 3.55 axle ratio, 315/70r17
Valair, south bend, etc. are gimmicks (other than their dual/triple disks) imho. I thought someone here may appreciate to know there’s something off-the-shelf that can work for you and nowhere near a grand to buy and can hold up to normal tow rig use with modest power adders.
