Title: Finding out whats inside your Rancho box Post by: Stefan Rossi on October 19, 2012, 01:17:34 am Is there any way of finding out from Rancho what my gearbox has in it?
It's a pro street but the guy I brought it off (brand new) didn't know the spec. When I drove it for the first time I found it has a close 3rd gear, then I thought 4th would be close too but I shifted and 4th was very long. maybe 0.89 not sure. I have no idea on the r&p or anything and I'm looking at selling it to upgrade to a pro drag. Can I phone up Rancho with the serial number and will they have the spec? All the other pro streets I've driven didn't have a close 3rd in them :s Regards, Stef Title: Re: Finding out whats inside your Rancho box Post by: Stefan Rossi on October 23, 2012, 01:52:55 am Can anyone help at all?

Lol here's what you do, is the trans in the car with an engine? If so, it's much harder. If there is no engine, stick a clutch disk on the input shaft and make a mark somewhere on the outside of it. Mark one of the splines on the axle, or mark the drum and backing plate. Put it in 1st and turn the clutch disk until the axle turns 1 time. Make note of how many times the clutch disk turns. Do it in every gear and post them here. We will be able to tell you what the most likely ratios are.
