Product Description

With these replacement/optional differential o-rings, you can improve the consistency and predictability of your 2.0 Buggy or Truggy! TKR5144B differential o-rings were used during development to boost stability when landing jumps or in rhythm sections, as well as give more acceleration and consistency during long runs or bash sessions. They achieve many of the same benefits as the new differential shims (TKR5144) by moving some of the resistance “work” from the oil to the o-rings and allowing the use of lighter differential oil.

TKR5144B is a direct replacement/option for TKR5144 and is compatible with all other new differential parts (TKR9115B, TKR9145 and TKR9150B) and existing 2.0 differential parts (TKR5112X, TKR5114XB, TKR9115, TKR5144, TKR5145B, TKR9112, TKR9114, TKR9115, TKR9149, TKR9149A, and TKR9150). They are also compatible with the EB/ET410 line of vehicles and are recommended to be used on all track surfaces.

Feel of TKR5144B

Initial/Breakaway Resistance Higher than TKR5144
Continuous Resistance Higher than TKR5144

With TKR5144B you may feel additional resistance before the internal gears begin to rotate and the added resistance will stay once they begin spinning.

Recommended Oil

Please read the setup documents below for our recommended configuration and oils if using several of the new differential parts together (TKR9115B case, TKR5144B o-rings, TKR9145 shims, and TKR9150B gears).

During testing, we observed that TKR5144B feels as if heavier was used than the prior TKR5144 o-rings. When transitioning from TKR5144 to TKR5144B, please reduce the oil weight by 1,000 to 2,000 cst.
