5.0 definitely getting one for the front

the product is great it eliminates the spider gears. i think the less moving parts there are the less can go wrong. i was suprised of the quality of the steel. you dont see steel like that every day unless your the machinist that makes the product. a varey hard steel and a nice blueish tint

Q: I just found out about this product and looking like what I have been looking for sense I purchased this truck in 1990. My truck is a 1990 3/4 ton, extended cab, Chevy Silverado 6 lug K2500. I plan on counting the rear end bolts when I get home. But this looks like the correct spider replacement for my applicaton. Can you confirm? thanks, Brad Answer this question
