Stiff Diff

[Mudder]

I just installed a TR Quick diff along with a Vertigo Monster Locker Differential Spool, Installed FLM diff cups,Dark Soul Axles and FLM drive cups. When i rotate the axles it seems real stiff. Is this normal??

The FLM drive cups are really tight/stiff in mine. Like crazy tight. Runs fine. Always wondered myself.

When i had them in the stock diff it wasn't that tight

Best think to do, I think, Is rotate and check the drive train during assemby when adding or even just building. Any binding, rubbing or tightness is not good.

your drivetrain needs to be smooth and turn easy, or you will fry your clutch, get reduced hp to the wheels, and possibly overheat components in the drivetrain. it is not good.
