I have a SAS conversion on a 90' Amigo, with the stock 2.6L, 5-sp manual MUA5, toyota 85 solid axle, with the minimal modifications. Foothill offroad in Auburn, CA did the conversion. It was their first Isuzu, after several Toyotas. They ended up replacing the Toy PU brakes with Land Cruiser components, and spacers. The easiest, straight-forward axle replacement, with Foothill custon crossover sterring, located the front axle in approximately the stock IFS position. This utilizes the stock Isuzu steering box with a custon pitman arm, drag link and. The front axle, spring over, makes for aprox a 6-inch lift, with a very short front driveshaft, and a very steep front driveshaft angle. To keep the unit from pulling apart at droop, they clearanced the stock t-case brace, ground the Toyota front drive shaft u-joint within an RCH <img border="0" title="" alt="[Big Grin]" src="images/icons/grin.gif" /> of splinter, and installed a limiting strap. With the STOCK front axle location,
I don't see how you can get by without the limiting strap . On a 30 deg ramp, the front ramps "604", and the strap is tight as a drum. Any more and the front shaft goes, BING $$$$$$$$$$ <img border="0" title="" alt="[Big Grin]" src="images/icons/grin.gif" /> <img border="0" title="" alt="[Big Grin]" src="images/icons/grin.gif" /> The rear was completed SAS, with the stock springs, and custom u-bolt flip, stainless brake lines, etc. Rancho 9000s were used at all 4 corners. They are at their softest settings, and I would consider going to a softer shock, as the tunability is wasted on the 5/5 setting. The vehicle is stable at 65 mph with 33-inch Dunlop MTs, and averages 18 MPG. I have locked the brakes at 65 mph in a wet parking lot and skidded in a controlled straight line to a stop. The more I wheel and progress to harder, 3-dimensional off camber boulder terrain, and see exploded driveshafts due to improper setup, and then drive 65 mph to work on the freeway, the more I appreciate the exellence of the Foothill project. I can't recommend their work highly enough. Hope this is informative. If I didn't worry about giving my son the option of a college education, I would convert the Toy axle birfields to Dana U-joints and a TLC Reverse pinion setup to reduce the driveshaft angle. $$$$$$ <img border="0" title="" alt="[Smile]" src="images/icons/smile.gif" /> <img border="0" title="" alt="[Smile]" src="images/icons/smile.gif" /> <img border="0" title="" alt="[Smile]" src="images/icons/smile.gif" />
