im in prosses of building a 9" for my XJ. i think the name of the company i saw before was blue torch. really nice conversion kit. does anyone know of any other kits out there? TIA,
Bill

 

i know theres a metric ton of universal weld on disc brake kits to use chevy 3/4 ton calipers.

 

Bill whats the 9" out of ? Some the Lincolns had a factory 4 wheel disc set up on them.

i dont know. i bought it from jake king. all i know is that the WMS-WMS is the same. im going to get perches in the month and get them mocked up. then weld the shock mounts up higher so there will be nothing lower than the pumpkin. pull the axles, and have the housing hot tanked. and then let it sit till next year or when i can afford alloy axles and a locker. im not sure about gears though. any suggestions on that? i want to stay between 3"-4.5" and know bigger than a 33" tire.

 

I think you are limited to 4.56 in the front d30 and 4.56 was what we put in Derek's w/33s. It worked nice together and felt slightly more aggressive than stock tire/gear setup. A 9 inch will be sweet in there and I bet you can get some brake ideas from Currie but they don't care how much it costs.

 

d30 will support 4.88's

 

dereks did feel quite a bit more aggressive. i was leaning towards 4.56's. ididnt think that going from 3:55 up to 3:73 would be worth it. but if i stay with 31" tires, is going to a 4:56 setup worth it?

 

If you go to 4.56 and stay w/31s it'll pull real good but you will be running higher revs out on the highway.

 

so what about a 4:10 setup? am i right that 3:73 would be a waste of time?

 

You said you may potentially go with 33's correct? If so go 4.56's.

 

Yep, if you maybe go 33's then go 4.56. I can tell a difference in mine from 31's to 32's with the 3.55's.

 

ok, so if i go from a 31 to a 32 and straty away from the 33's, would i go to a 4:10 setup? im just trying to get some ideas. i did forget to mention that this would be driven approximately 20 miles a day.

 

Thats exactly what I have Planned. 4:10's and 32's until I can build and not use it as a DD

 

Not that it's needed but you can get 5.38's for a Dana 30

thats for a low pinion dana 30, 4.88 is max for the high pinion dana30 found in 84-99 cherokees.

and putting money into a low pinion 30 is a poor investment anyway
