I have a con FE that started slipping and then seized to the flywheel. Is there anyway to free them up to move the truck around easier, starting in gear currently to move it. What should be my next clutch no heavy pulling or track time but the FE didn't last as long as i expected.

how did you break in the clutch? was it new from sb?

nc_ram

Break in was 200+ miles of city driving no towing or hard starts. It was new from sb and the flywheel was new also. I should be well below the power rating for this clutch

matthais

If I can recal the fe is rated at 500 or 550 ceramic. I have had issues with them not disingauging but call Peter at sb he should be able to help good people. So you must have been slipping hard and kept slipping to weld it to the flywheel tho.

Spoke with Peter today going with the 3250 dual disc, he was very helpful. It was in the snow of all times shifted to 5th and I didn't feel it slip right away, thought the tires spun instead of the clutch. He said the cold could have been a factor in this but that the 3250 would be better for my driving style.

are they gonna cut you a deal?

i hate my valair...

dont get me wronge its a decent clutch for the price, but for what i wanted this clut ch is def not capable of holding.

i can slip it in 4th and 5th gear and i only dynoed at 450hp/ 936ftlbs.

oh and uh the clutch is 600hp/1100ftlbs...

matthais

every clutch company has there lemons. Ask around talk to the local dyno shops they will know what holds.

i talked to valair they said i may be eating it up due to rpm and torque ranges... my torque curve comes in late rpm

matthais

Do you have a cracked exhaust manifold? I did had no low end same thing happend with clutches they werent being broken in correctly with the tq curve comming in too late.

I was pleased with the sb just went sooner than expected (50,000 miles) but it sounds like I didn't pick the correct one for my driving style. Time will tell if the 3250 is better and I have no complaints with sb or there customer service.

i wish i could have a fforded the sb dd 3850 sfi cltch...


i will be updating to this in the future.....

no exhaust leak just a 16cm housing on a stock charger and it dont light till 1900rpm. does leak aound the echaust housing... i see 3200-3850rpm a lot... truck likes it better up there

Ramdriver15

they have been super great to wok with, just wish i would have gone with what i wanted originaly... their clutch would be outstanding if i daily drove my truck but id like to be able to hook to a sled, or even launch in 3rd gear... but i couldnt...

I also seized my con fe to the flywheel. I wasn't being very nice to it when I did it though. Went with the SB dd3250 after first trying a couple Haisley dd. Very happy with the 3250 now.
