Howdy, I know the 4+ stuff is great from Man-a-fre, but does anyone else make a kit to flip the front u bolts? I may fab up a set for the rear, but with the one ubolt jumping the diff housing I am going to buy a set for the front.

Thanks!

Beware the simple ones everyone else sells. They work for a mini but Cruisers need the extra locating plate! Given your fab skills I'm surprised you are considering buying them! The top plate is super easy and the locating plate just will take some effort but not that big of a deal. The bottom plate could easily be made with some 1/4" strap and some stitches. The ones i sold Sharkbait are the 4+ ones....very good design! Check them out and reverse engineer them. Don't even feel bad about it either as they had no problem screwing us around on the Raffle truck front bumper! :rant:

Well for that matter Drew, for someone with your fab skills, why even run U-bolts? I bet you could whip up a mean coil & 4-link.... :weld:

Man, I think you guys are over estimating my skills... I have always subscribed to the don't mess around with brakes and steering school. Might be simple enough just to buy them and get moving then spending a weekend on ubolt plates.

Thanks! :thumb:

What are you worried about? The U-bolts hold everything together....don't mess with them and the rest should hold! :lmao::lmao: Build your own and the money you'll save can buy 1/2 of your plasma cutter!

Did anyone see the BJ70's U-bolt on Metal Masher? :eek:

Do like the typical PO would - just weld the axle to the springs! Problem solved!

I will probably do the same mod soon. I trashed my u bolts at moab. the drug on a few rocks and i guess i could have prevented it, but oh well.

the 4+ ones look nice.... i think i may just go that route..

The flip kit I fab'd was one of the easier things I've done on my rig. You can see pics of the work in this thread http://risingsun4x4club.org/forum2/showthread.php?t=6861&page=2

I say build it yourself. I got square u-bolts made at Denver Spring, cut out the top plates and welded on some spring perches from 4wp to them. Then cut out the bottom plates. The bottom plates did require a groove cut into them on a mill to hold the u-bolts in place. Cutting the grooves is the only tough part that I couldn't do, but luckily I had access to a machine shop at the time. All steel was 1/4" (maybe 3/8" for bottom plates). The offset front passenger was achieved by cutting the perch in half for one side and fabbing the other side out of a peice of angle.

we could use some pics... I just looked at that ubolt last night. I'll have to snap a pic of the break.

When this subject came up on the CCoT board some years ago, several posters showed their home-brew designs which were simple, easy to fab and much beefier than the store-bought variety.

Are you wanting to flip the bolts just for clearance? Years ago Land Cruiser Advanced Handling made a kit that got the u bolts above the bottom of the axle without the need to flip them. It was a pretty cleaver design that looked quite strong. Now this is from memory about from about 15 years ago, I believe that it consisted of plate steel shaped to fit the curvature of bottom half diameter of your axle tube. Gusseted horizontal flanges with holes for the u bolts were welded onto the curved plate at the half axle tube diameter. The u bolts, which would need to be shortened, clamped the flange leaving the bolts above the bottom of the axle housing.

Hope that this made some type of sense.:)

It's pretty hard to beat the 4+ ones in terms of beefiness. While i'm all for fabbing sometimes it's worth it to buy em and slap em on when you factor in your time, price of steel, scrap etc. No doubt you could probably fab some though Drew.

Wes, your totally on in this case. By the time I drive down to denver, pick up the steel, fab it up, drill, measure, grind, cuss, and paint the plates, then buy new ubolts, and then fab up the spring perches for the top... it is easier to buy them this time around.

I appreciate it everyone! :thumb:

1" for $300 is totally worth it. I just bet you wish you could get 4" for 1200 right ;)

Nope just doing the front... 150 works out about right. And I can get it done in an hour verse a day... :D

You get a full inch of clearance? Wow. If I ever seriously wheel my 40 again, maybe I'll buy these.
