I wasn't happy at all with a Hayden clutch. Friggin thing wouldn't come on unless I pulled a huge hill, loaded, temps up near 240 and even then I had to pull over, idle for 30 sec or so and THEN it could come on. I got a Horton through work and will never go back unless it's OEM. The Horton clutch was a bit pricey but worth it. I'll see if my boss still has the receipts tomorrow and post the part #.
Which grade Hayden did you put on? They have three different lines IIRC in addition to duty rating and thermal vs speed. I have one waiting to go on my GMC. I'll let you guys know what I think of it.
