Default High-clearance U-bolt/spring plates

Other than the Dynatrac setup, who else makes high-clearance U-bolt/spring plates? I saw a setup that mounts the spring plate under the spring (not over like the Dynatrac), but can't remember who made it.

You want the plate under the spring, but still want your bolt threads facing up?

Or are you talking about the old Con-Ferr design that had a skid built into the plate with the u-bolt buts recessed?

Get some square u-bolts and make your own plate to go over the axle.

I used a set (ubolts and mounting plates) from a 2003 Chevy 1/2 ton pickup. I flipped them over and they fit my 8.8 tubes perfect. I will try to get pics later.
And they were much cheaper than that.

That's an option. I still have the spring plates from the '90 GW (which was spring-over), and could probably use those. Any suggestions on where to find square U-bolts?

The Dynatrac setup places the spring plate up top. The other design I referred to (it's a name brand product, too) leaves the spring plate under the spring, but the sides of the spring plate "step up" to get the bolt heads above the lowermost part of the spring. I'm not referring to the Conn-Ferr design with the skid plates (which essentially leave the nuts in the same relative position as a normal spring plate. Hopefully, my description here makes sense...it's kind of difficult to describe without a pic.

I know what ones you are talking about. They run 250 for a set of 2. I looked into them in the spring.

Can't remember the name though.

Problem that most run into is in the front. I have yet to see a flip kit for the front d-30.

Thanks for the pics, Nvrenuf. I'll look into that option.

MuddyPaws - If you look at the Dynatrac link in my first post, there's a version for the Dana 30.



I'm looking at options for my CJ-10a conversion project. I'll reuse the front setup, as everything's rust-free and in nice shape. I have to buy U-bolts for the Isuzu D44 rear axle, and just thought I'd consider a high-clearance setup in the process. However, the existing setups are too pricey for the benefit I'd get from them (with the exception of the OEM setups from other vehicles (e.g. - Nvrenuf's Chevy setup, Dodge spring plates, etc.). Since I have the front & rear spring plates from the '90 GW donor vehicle, would square U-bolts work with these flat plates? I can't tell from the Dynatrac photo of the top plate is just flat and has a very small contact patch with the axle tube, or of there's a shaped piece that mounts in between the plate and the axle tube.

Do it like the dynatrac and add a perch under the flat plate on top and parallel to the bottom one.

I have mine made at a spring shop by me- they end up around $5-6 each, IIRC

Dodge trucks... I think late 70's. Not sure if it's still a dealer part or not. I would think no.
