Anyone see the new show Exteme 4X4 yesterday, 1/1/05? They installed the Kelderman air suspension on a new 2500, 10" of lift and some huge tires, pretty cool setup. The show showed all the parts and what is involved in installing it. The show always has the same episode on on Saturday and Sunday so it will be on again this afternoon, it shows here at 1:00 EST. Then on Trucks TV at 1:30 they put a complete Bully Dog system on a Duramax and then towed a 130,000 lb trailer!! pretty crazy stuff. Check it out today if you have a chance.
