B4.1 Gear diff
 

Have any body tried the gear diff from AE in their B4.1:drool:

Yep, I'm using it since 2 months. Works great! Without any changes can you put the metrical beared diffgear in your B4.1! No leaking, very smooth!

If it's not too much trouble, what are the product numbers we're looking for to purchase every needed bit for this mod? (And will it work on the old B4 too?)

For old B4 you will need: 1 x ASC9818 Team Associated Rear Arm Mount/Chassis Plate, 1 x ASC9827 Team Associated Complete Gear Differential, 1 x ASC9832 Team Associated 10x16mm Ball Bearing (2), 1 x ASC9826 Team Associated Transmission Case for Gear Differential.

I use stadard setup filled with black grease, and 100% satisfaction.

I used a geared diff all last season in my B4, filled it with black greae and it worked really well.
