4WD S10 Frame Swap
We no longer sell kits specifically for the 4wd S10 frames!
The front frame half is completely different on the 4WD. Stock S10 frame holes are different, requiring new reference points for mounting of our cab stands. Shown is a 2.8l V6 and 4WD trans with transfer case attached. A new transmission crossmember would have to be constructed. The frame also angles out a few degrees requiring minor modifications to the front cab mount washers on the cab floor. When running a V8, the transfer case will sit directly above the torsion bar crossmember. A "clocking ring" will be required to rotate the transfer case to a horizontal plane. Any good 4WD shop should be able to tell you if this is available for your transmission. Without the clocking ring the downward angle of the transfer case will force you to raise the engine quite high and cause all sorts of interference issues.
Rear track width works fine. The front will require a slightly larger backspace measurement on the front wheels.
The front frame horns are also completely different.
A few notes to keep in mind regarding the use of an 4WD S10 frame under your AD truck.
• No billet wheel spacers are required although you may still use them depending on your wheel of choice.
• ADE does not build 4WD trucks normally but the S10 is a tried and true platform with many off-road upgrades available in the aftermarket. We would not be a good source for questions regarding what is the largest tire size that will work, is the transfer case strong enough for a V8, etc, etc. You'll need to consult off road specialists for these questions.
• You may need to adjust the position of the engine/trans package so the transfer case output clears the torsion bar crossmember. This may require minor modifications to the firewall or floor. This will require a clocking ring.
