I am about to buy some lockers for my 86 CJ7, I has the original Wide Trac Dana 30. I think the Wide Trac Dana 30 is a 30 spline and the Narrow Trac is a 27 spline but not 100% sure. Can somone confirm this or correct me if im wrong.

If it is stock you have 27. AFAIK - 30 splines are strictly after market and require a carrier upgrade.

Great article here -->> Jeep Drivetrain Components - Jp Magazine

You can see axle kits that have 30 splines say only for after market carriers -->> G2 Axle and Gear Axle Kits - Axle Upgrade Kits

And here -->> Alloy USA Chromoly Axle Kits - Axle Upgrade Kits

CJ is correct, both narrow and wide tracks come stock with 27 spline axles.

If your going to buy a locker you might want to up grade to the 30 spline now and not worry about it anymore.

If you're running big HP V8 - ditch the D30 and go for a D44 or bigger.
