FS: Z31T axle adapter flanges for S30 + R200. Slim design

Recommended Posts

Had a post about the design process and checking of clearance in the Drivetrain section. Now here's the sale post of the adapters I've made several sets of.


Quick Description:

Z31T weld on adapter Flanges to fit Z31T CV axles into S30 chassis with the use of an R200.


Long Description:

They weld onto the outboard axle flange to provide a bolt pattern that will fit Z31 Turbo axles. The axles are NLA but you can find them on forums, craigslist, car-part.com, ebay, etc. They are a very strong axle. It is for an R200 diff, not stock R180. Rockauto has recently has some new style axles. The CV type is tripod which is a little weaker and the axle shaft diameter is fair bit smaller. no idea how much power they will support.
1) They are weld on style. They must be welded by someone with a little experience since you're welding to the stock CAST flange. They also must be bolted down if you want the flange to remain flat. They also must be centered into the square relief. The Square flange IS NOT concentric to the rotational axis and it must be shimmed and positioned correctly so that there is minimal runout.

2) They require grinding the stub axle nut and shaft between 1/16-1/8" depending on if its 240 or 280 style. Basically enough so that the flange is flat.

3) They still require flipping the cages inside the CV. I've measured that on the Driverside it would be fine (only 2.5mm of clearance) without, but I'd do it anyways. Passenger side is tighter and needs it.

4). Material is mild steel. Paint or powdercoat (if you remove the stock flange to weld) at your own will to prevent corrosion.


I've got a PDF of the instructions for install attached.


Sets are $195 USD shipped.

I have 1 set that is already welded to the 260z/280z companion flange. It's not painted but perfectly centered and has quality tig weld on it. $295USD shipped.

I also built a jig to help in welding. It locates the flange on the stock locating ring on your stock companion flange. I can rent it out for shipping costs and security deposit and such, but if you know how to shim something and use a Dial indicator to check runout, may not need it.
