They were both Richmond Street Gears, so do you think the added weight had any effect on this breakage??

It may have but I doubt it, how much does the car weigh and what kind of RPM are you leaving at? .004 is kind of tight on the BL this may have had something to do with it breaking so soon. Also what kind of rear cover do you have the housing could be moving around and that is not going to help.

Car weighs 3300 with me in it. When it broke I was launching at 3200 rpm, It just has the stock cover on it.

Use billet caps and US GEAR (Strange) Pro gears, and go racing.Joe

I'd go back to.012 and easy out of the water!

I used Mark Williams(part #58100) needs minor machining as I remember. I think Moser also makes them. I would spend money on the caps before I spent on the preload covers.
