It is an XJ dana 30. Where did you see the build? A YJ would have the spring perches already, but where would the fun be in that.
Just a quick update so everyone knows.
I am doing a solid axle swap on my blazer. The RC lift caused me too many problems and I am running tougher trails now so custom IFS or SAS.
Dana 30 front diff with 4.56 gears open for now because I drive on icy streets and I can't justify a selectable yet.
Stock 8.6" 10 bolt with 4.56 gears and a yukon grizzly.
Front will be 4" waggy leaf springs in a spring under configuration
Rear will be a stock s10 blazer pack with an extra main leaf cut off at the eyes in a spring over configuration.
T case will be a first gen 233 with the fixed front yoke out put.
Tire size will be the 33x10.5x15's I have now with a plan to go to 35x12.5x15 KM2's.
I hope to keep the blazer as low as possible but with the 2" body lift I may have a couple of issues.
