Im gonna start rebuilding my tranny pretty soon and I was looking to get a super low gear ratio for my brumby. Does anybody know who sells aftermarket gear ratios for subarus?
 
JG,

If your brumby runs the original 4 speed box I don't think there are many options out there.

If you're running an EJ series gearbox there are plenty of options from changing gear ratios in the forward gears to changing the final diff ratio.

The scorpion low range is basically the L series low range, just re-engineered and priced high IMO. You can get the same thing from an L series gear box, but if you're running 4.111 or 4.44 diff ratios you'll need to shave some meat from the crown wheel to make it all fit and work happily.

Good luck with it, gearboxes still do my head in!

Cheers

thanks for the help. Im currently running a 4 speed which is all but shot so im looking for a new one. Im actually considering changing basically the whole running gear by taking out the ea81 and 4 speed tranny and replacing it with an ej22 and a 5 speed. The transfer case is also shot. Do u know if the engine, tranny, and differential will drop into a brumby running gear without any problems
 
Engine crossmember shouldn't be too much trouble, need lift or a spacer between the chassis and engine crossmember if not lifted.

Gearbox crossmember needs to be fabricated. Radiator port size increased to 40mm. Cut down the EJ wiring and splice in the wires that need power to run the system.

You'll need to sort out a tail shaft and gear linkages. I'm not sure if the tail shaft needs lengthening or shortening and I don't know what happens with the gear linkages.

No, but if it's for the buggy, have a search on USMB for the "T case mod"

Daza.
