OK, so im a little curious. I have a LSD rear end WITH ventilated disc brakes, and LSD. Im guessing GLS-SE. What i basically want to know is, are there any differences from GLS-SE and GSL? I know axle lenghts are different, but is the LSD the same unit? Do the axles use the same splining?

 

Look at the bottom of the page. You will see related threads.

 

GSL-SE LSD's have 3 clutch plates and the GSL's have 4 IIRC. Different rear end gear ratios and depending on what year GSL you get, the axles will have smaller bearings . All -SE's came with Big bearing axles. All GSL's came in 4x110, -SE's in 4x114.3

Hope that helps

 

All the info is here =

The only difference is the LSD side gears , GSL-SE / S-3 = 26 spline & S-2 small axle = 24 spline !

 

axles are different, bolt pattern is different for 14-inch wheels on SE. GSL has 4-wheel disc, 3.90 ratio, SE has 4.10 ratio.
