Hey guys so I need a little advice here. I am building a 2001 Chevy Blazer LS 4x4 2 door with the 4.3 vortec. About 6 months ago I put a two and a half inch rough country suspension lift kit on it and to do this you know the bracket for the front diff must be cut and a new one bolted on. Now I have the money I have decided I want to get the 6" lift from RC. So my question is does anyone know if the front differential will still work with the 6-in kit or is it garbage and will I have to get a new one and start over? Thanks

Also I'm having problems with my fuel pressure regulator going bad over and over so I know my spider is bad what is the best spider upgrade for a 2001 4.3 vortec I use this vehicle in a lot of off-road and mudbug events?

 

Regulator constantly blowing would not be caused by a bad injection spider, though upgrading to an MPFI spider is a good thing anyways, check your fuel lines for kinks and flow issues, especially the return. as far as the lift, you should be fine, just bolt on whatever bracket it comes with or reuse the current one, just keep your CV and UV axle/joint angles as flat as you can.
