u can fit the hardened steel genesis spur gears to ur hubs that the green and yellow gears have (the red ones dont have them) that will sure cure the stripping prob, so long as everything else on the car is up to scratch and tight - especially engine mounts and correct gear mesh.

u will need to find some hardened steel pinions too really, but cens single piece 14/18 is steel, sorry i dont have a part number for it handy, but its the plain one, not the blue and black geared one - theyre alloy and will die in seconds on those genesis spurs.

expect the weight of the spurs to effect performance tho, they are heavy things...

before u go rushing out to get the bits - are u sure ur gear mesh is spot on and the engine is tight, threadlocked and set square to the spurs? Diff housing and brake seat are solid and holding the shaft well? Is the chassis still straight?

just checkin...
