Hello
I've been searching all over to see if there is a way to put larger diameter front rotors on a k5. However my search has been to no avail. I have found out that the 3/4 ton dana 44 spindles can be swapped to incorporate the larger 12.48 inch rotors. The 3/4 ton calipers are also a D52 style and could be replaced by willwood dual piston calipers.

However the biggest problem with this is I do not want to have an 8 lug rims in the front and 6 in the back. I already have a well built 12 bolt in the rear so I have no intention of swapping axles ether. So is there some other options I could explore? I've run out of ideas and could use some experienced advice.

Thanks, Cyrus

i know the last of the k5's had larger rotors and could only use 16" rims try looking up for a 91 or 92

As far as I can tell the only rotors you can buy for blazers are the 11.85's. And the next gens actually decreased in diameter. However you were somewhat correct because 89-91 suburbans did change and have 11.90" rotors. Don't know if it would make any significant difference to braking but it looks like my best option. Thanks for the help=)

is the reason you are going with bigger rotors is to have greater stopping power? because a power assist sytem off a chevy diesel will do it, they work great, it uses the power steering pump to power the brakes

I figure that having larger diameter rotors would help allot to keep temps down as well as provide better braking capacity. I have looked up gm's HydroBoost and it is pretty intriguing, but it is a fairly costly set up=( I might just have to try it out though.

look in the junkyards for a diesel chevy, if you get the big stuff there, and plumb it all in that could keep the cost down, as for temps, if you went with slotted (not drilled they eat the pads) with non ceramic pads it will help with the heating and warping. i recently was talking to a napa parts guy and he told me the premium ceramic pads eat rotors from excessive heat, the power brake setups are waesome, you will be amazed at the extra stopping power
