Fitting Dual Range caseings to the Vortex SR FT box .

Featured Replies

Hi all , I lucked out and located a turbo spider full time 4WD manual Vortex here in Aus . I can't get anyone to part with a dual range full time L box here so this is the next best thing .

 

When changing the front Vortex gearbox caseings for the dual range pair am I likely to strike problems getting the diff pinion height right in relation to the crownwheel ? I do realise that I'm going to need the mainshaft and gears from an RX part time box to match up with the Vortex's layshaft gears .

Actually I'd prefer the non turbo ratios because they're closer and up the box a little shorter which helps with larger diametre wheels and overall "gearing" . I'm not quite sure which gears are part of the shafts In an L box but suspect 1-2 are which leaves 3-4-5 possible to mix n match .

 

Just in case anyone wants to know part of the reason for wanting the dual ranges its because of the lack of front diff ratios with the propper full time boxes . 3.7's are around but 3.9's are rocking horse doo doo here in Kangaroo country . I also want to go off the beaten track ocasionally and need to have something to help the EA82T "torque mountain" get me there in one piece .

 

Any help appreciated , thanks Adrian .
