You can put manual hubs on the gen 2's and just unbolt the rear drive shaft when towing and tie it up on the frame. Another option is to get a driveshaft disconnect which any driveshaft shop can Do for you
Watching these two trucks move across the terrain with animal like prowlness and they ride every bit as good as my basically stock none lifted 95. The king's just soak up every pot hole and divet in the road truely solid builds
well that cam gear being off will either advance or retard that cam by 5ish degrees not really a good thing to be out, its kinda hard to tell by the picture could be camera angle to me it looks like half a tooth which could mean either one head maybe both have been milled over spec so it is...
It's your ride buy it new buy it now because in 10 years there may not be a oem replacement.... then you'll have to buy the carling and just not ever replace it again.
Also when it stops working you also lose brake lights and it happens without you knowing it. I've been driving these trucks a long time trust me that hazard switch is no good. But if you want to keep it stock buy a new one don't keep that brittle old switch in there.
