Ok after hours of wrenching i replaced the thick fluid and went 7k and 5k and its much easier to handle but i realized that the diff was locking up when i installed the drive cups soo i took the dremel to the cup where it rides against the bearing and its really smooth. I guess someone didnt do there homework and see that the FLM cups would work with the diff that comes with the kit!

I'm gonna go out on a limb and say that the Hybrids haven't been altered in order to use the caster racing diffs, in which case the Hybrids would still work with other brands like ofna & hotbodies ( and LST diff internals too ). In that case you could start from scratch with new internals which are easier to find parts for ( never known someone make such a meal out of assembling diffs... ), or you can go to ebay & type in 'caster racing'- you will find various bits of diff including the ring, pinion & spider gears. Trouble is they sell various different models with different didds, so that complicates things.

You may be able to look up part numbers on the caster website, though you won't get any joy when it comes to asking about compatibility; FLM could have gone with any brand of diffs to fit their hybrid bulks, but that brand has no input or affililation with FLM. I'd just try and find out exactly which model(s) the diffs are for, that will make it easier to find the right spares.

Our Slipperential internal gears will work with the FLM diffs - the gaskets and cross pins are different, but the pins should work if needed - the actual gears, shims and O-Rings should be a direct replacement.

Quick note on the crunchy gears - the gasket that seals the ring gear and diff cup is important - if it is too thick, the gears inside will have a loose mesh and will therefore be prone to stripping. The diffs are prebuilt with paper gasket IIRC, but include a blue thicker gasket which may or may not cause backlash issues - make sure the gears have a smooth, but not sloppy mesh(I like a slight notch on a new diff build to allow for break-in).

Guys, please give the part number of the differential, which can be replaced.
I strongly twisted bolt in the differential housing and damaged threads. Ordered this one, it does not fit. I want to buy the whole assembly, and to know what is suitable for replacement in the Ultimate Hybrid Bulk (FLM18750)

Thank you very much !!!

You need a Caster racing diff case- unfortunately I don't know which one exactly; if you contact FLM directly they may be able to help...
