The hoses are not the expensive part,it's the junction blocks required that are expensive.Those kits have everything needed and trying to piece a kit together yourself will always end up cost more $$$.

Skip anything as important like brake lines on fleabay.Get good lines that are DOT approved.

You really want to buy cheap parts that your life depends on?

Nope lol. I am leaning towards purchasing the Goodridge G-Stop 4" extended SS braided brake line kit. Out of curiosity, why does JBA's kit cost twice as much?

From the link you posted looks like a halfa$$ed kit with straight blocks.Will require modifing from the look at the pics.I'd be wary also since in '06 and '07 the KJ requires 4 brake lines and not 3 like '02-'05's.The JBA kit comes with the correct OEM looking junction blocks so it is a total bolt in kit with no mods needed,hence the higher cost.I bought that same kit from JBA second hand(new in box though) and came in very handy when I SFA'd my KJ since it then just needed longer hoses and the correct banjo ends for the Ford and Chevy calipers.

I know my rear brake line was a bow string(really maxed out,almost broke) with the standard length OME rear lifted shocks(not the N132L's),totally unsafe.The fronts are long enough but the braided lines help with the braking feel anyways so change all 3.

Do they make extended rubber brake lines for the KJ? If they do, I am having a hard time locating them.

No.

The fronts are really not needed,the rear(s) are.Changing the fronts to braided lines will produce a much firmer pedal feel since they won't expand like rubber lines.

Well, it looks like I have no other option but to buy JBA's SS braided brake hose kit for 4-6" lift. Just digging the endless money pit deeper. Thanks for the help!
