flm bulks
 

has anyone have these combo bulks,do they need any work to make them fit.am asking about the ones that take stock gearing,thanks

As far as I know, you will not need to do any modification on theses things to make them work. They are ready to install.

I have not had to modify anything to make them fit. I ran mine with the maximizer cups for added strength.

thanks guys just havent had much luck recently with other products by them. alum.trans,diff.cup

I'm having a bad feeling about this.

in what way

Honostly, don't bother. I have them and they don't come supplied with the correct hinge pins:

Today I had to hacksaw the "kick up" part off the rear bulkhead, so the normal hinge pins fit and I can fit my UE Widetrac arms.

Other bulkheads don't have a kickup on them and allow the use of ordinary hinge pins, the FLMs don't.

You mean the FLM hybrids wont accept the hinge pins of the UE racerX suspension?

just want to clear this up.am asking about the regular combo diffs not the hybirds.do you need to modify them to work.i have the gm chassis. thanks

no you dont.

The UE suspension fits so well but the Bulks have some daft design.

I had to modify mine to use them properly, other wise you will either get alot of play or they will be really stiff. There are better bulkheads out there for the price.
