VHR + FD Gear Ratio upgrades - 3.9 and 4.08

blumango · 11-13-2013, 04:23 AM

Hi,

Does anyone know what the correct space between the gears should be? Without this info, I won't know how much I should shim.

Please advise.

Thanks.

I have no clue but if I were you I would take it to someone who knows what they are doing. I know if you don't have the backlash set right you will have catastrophic failure. Just my $0.02

I'm well aware. But I can't find some one in Singapore who has done this mod. If I can have these info, I can advise them and they can measure and shim accordingly

Got the Quaife on order. Can someone verify this is the OEM ring and pinion gear set I need to order from my local dealer? It is going into a 6M Diff.

M/T w/15" wheels = 4.083 = part number 38100-0C760

What is the main difference in the gears?

Did any one else who did this swap have the ABS and Traction slip lights come on after install? I've had it checked by Nissan and they said they found the lights and codes but couldn't find anything wrong. I did the gear swap and switched from open to the VLSD at the same time. The only thing I didn't replace was the drivers side output shaft, I had the passengers side ground down.
