There is a winch bumper for the Alpha. It is at Towbin Hummer in Las Vegas. Call them for the brand name and price. I think it is aroubt 895.00 w/o winch. The winch that works with it is the WARN 9000ti.
35's will fit. They will rub under extreme supsention flex. You can count on about a 15%-20% worse gas mileage. If you run 35"s on a H3 with an I5...it will be a DOG. With the Alpha 5.3 V8, you definately notice it being a little sluggish. If I put 35's on my Alpha, I would go up to a 4:35 in gearing to offset the tire size. As far as I know, there is NO programmer or Chip for the Alpha. I tried a Chevy Silvarado 5.3 EDGE programmer. It worked until I told the programmer to load the new programs into the Alpha's computer. At that point the programmer would not continue.
I have heard that the Magnaflow exhaust give you alittle more up top (3000 +RPM). But because of less back pressure you lose some torque. I am keeping my stock exhaust. I will upgrade the air box when something comes out.
Towing - 6000lbs, Acceleration - 8.65 0-60mph.
The I5 engine is great for offroad, less power but better MPG. The offroad situation where the Alpha's big engine pays off is in sand or deep mud.
I hope that helps. I came from 5 years with a very modified H2 ; (See my H2 Picture under the post about my new H3 Alpha), and I LOVE IT
