3.92 LSD for 2008 1500
I want to put a LSD in my 2008 1500, 5.7, 5 spd auto trans [545RFE], 3.92 gears, Build sheet shows DMHS 3.92 Axel Ratio, DRBS corporate 9.25 LD Rear Axel. Is this an LSD or is it Light Duty? I tow 6500 lb travel trailer. Cost? who makes it? How difficult? Thanks!

The DRBS is the axle housing, Corporate 9.25 LightDuty rear axle
i believe the 9.25 is the PINION Ring size

Mine is DMD with 3.55s
I don't believe that you have the Limited Slip Differential with the DMHS, ?
are you sure that you don't have sales code DMH 3.92 ? all axle codes seem to have 3 letters

then there are the LSDs
DSA $$ Anti-Spin Differential Rear Axle
DSD $$ Vari-Lok Progressive Rear Axle
DSE $$ Tru-Lok Front & Rear Axles
DSF $$ Elec Ltd Slip Differential Rr Axle
DSG $$ Elec Ltd Slip Differential Frt Axle

i believe these are for a Jeep (2 letters)
KJ Trac-Lok Differential Rear Axle
TJ Trac-Lok Differential Rear Axle
WJ Trac-Lok Differential Rear Axle
XJ Trac-Lok Differential Rear Axle
ZG Trac-Lok Differential Rear Axle
ZJ Trac-Lok Differential Rear Axle

these codes came from a 2008 PDF file

All codes have an S as the last letter on my paper work. Looking at it I think the S stands for standard equipment. Dropping the S I have DMH 3.92 Axel Ratio, and DRB Corporate 9.25 LD Rear Axel. If this is not an LSD how can I get one? Cost? Who makes it? Etc?? Thanks!!
