SOA finished (and the YJ passes emissions) pics

So I've only been working on the Jeep all summer [img]/ubbthreads/images/graemlins/crazy.gif[/img] but now it's finally done (mostly), inspected, passed the emissions dyno test today, and is on the road again.

Specs:
1990 dana 30 front, 4.10, '95 half shafts, lockright.
Ford 8.8 rear, 4.10, lockright.
258, weber 32/36, GM HEI, EGR, cat, no pulse air system.
33s, soon to be 35s.
SOA on stock YJ springs. 5 leaf in front, 6 leaf in back (5 leaf with extra main leaf with eyes cut off)
AA SYE, Cherokee front CV shaft shortened and balanced.
Homemade flat belly skid.
1.25" JKS body lift.
1" longer shackles.

Before:
SUA, sagging.



Springs and perches ready to go in:



After:



Flexing it up:




Emissions results:

HC: 1.15 grams per mile (limit 3.20)
CO: 16.87 grams per mile (limit 80.00)
NOx: 1.23 grams per mile (limit 3.50)

Not the biggest or best, but I'm pretty stoked. [img]/ubbthreads/images/graemlins/grin.gif[/img]

No real tech here, just sharing some pics, and taking up my allotted bandwidth for the day. [img]/ubbthreads/images/graemlins/grin.gif[/img]

Re: SOA finished (and the YJ passes emissions) pic

Yes, 35s are in my near future.

For steering -- right now it's just the stock parts. "Low Steer" [img]/ubbthreads/images/graemlins/wink.gif[/img] With the drop pitman arm that came with my original 4" SUA lift.

Doesn't seem too bad, but it does have a bit of bump steer. The well-documented problem with the link from the pitman arm to the passenger knuckle hitting the passenger side spring is the worst on passenger side wheel flexing up (stuff), and with the wheel turned to the right.

It's really not as bad as I thought it would be though, and right now it doesn't even hit unless she's flexed up quite a bit, and turned hard right. I'm going to try a small solution in the next week. I read about it in one of the rags.

Take an additonal leaf - the smallest leaf spring in a stock pack, and cut it so it's as long as the spring perch. Put it in the pack right next to the perch. Yes, it's essentially a lift block, if you want to call it that, but it's bolted in with the spring in the pack - held by the spring center pin, so it's really not an unsafe condition. It'll give you the lift of a single leaf - about 1/4", which is about all I should need. Won't miss by much, but it should miss.

Here's a shot of the interference, which I'm sure you've all seen before.



And yes, I'm goign to get thicker spring plates. [img]/ubbthreads/images/graemlins/grin.gif[/img]

Looks pretty good to me. Maybe next summer's project? This place is a bad influence. :P

How's it drive with no track bar?
