Clutch recommendations?

Hey. It's been a while....

Did an extensive search on the subject before posting this, I'll be brief.

I tow a 3200lb stump grinder with my '89 MJ, 4x4, 4.0, BA 10/5 (75K). Often backing up over curbs, decent inclines, and other assorted backing and jacking to get the machine over the stumps. Lots of clutch work in all transfer case ranges. Smoking the disc lately and getting chatter at take-off even when unladen.

Am I better off replacing the clutch with an OEM type, letting it be the weak link and burn up, before popping u-joints and toasting this light duty tranny? Or should I go with a heavier duty arrangement?

Also, does anyone know whether the LuK Pro Gold series is a double friction clutch like a Centerforce, or is it just a beefier version of a traditional clutch?

Thanks for any info.

i have not had any problems with the centerforce 2 on my 89 with the ba-10 trans.

2X on Centerforce, Hayes is good too but the Centerforce is better. I think the Hayes was also more money, but it's been a while so I'm not sure.

Centerforce clutches only really get the higher clamping force at high RPMs. Not really that much better at low speeds.

I put a Luk Gold in my XJ several years ago, but don't remember any of the friction material details.

I ignored the advice of a few here and went with the Centerforce, and had problems with the weights. When warm, they would not return from the 'deployed' position. It made it difficult to shift, almost impossible to engage first from a dead stop.
Always worked good starting out in the morning, only to piss me off down the road. It did however work normally for the first few weeks installed.

Go with the basic factory(OEM) unit, it's more than good enough for the 4.0.
