B44.1 diff gears

[topher2009]

Hi, is there a secret to the b44.1 bevel gears or an upgrade option from another car?

Running a b44.1 in the club off-road champs and going very well but keep killing the rear bevel gears. I am running a 5.5t in it so maybe a bit powerful but the diff seems to hold up, just the gears that don't! Might be the slipper a bit tight but just wondering if anyone back when these were newer did any gear upgrade!

Thanks

Chris
