Machined Leaf Spring / Rear Shock Mounts - Got a photo?

[Alpha X]

Who has a decent photo of a machined Leaf Spring / Rear Shock Mount?
Not a factory mount, or a bent and welded mount. Here's an example in this picture. They exist, I'm just looking for better photos of one.
Made from what appears to be a block of steel, machined to mount the Leaf Springs, and keep the U-Bolt nuts protected, and raise the Shock mounting for clearance. Thanks in advance.

Those are called Tomp low profile shock mounts

If anybody has these low profile shock mounts sitting on a shelf collecting dust and would like to sell them, feel free to PM me.

Yeah good luck with that!

I was looking for awhile too. If you want photos to make your own they can be found using a Google search with a focus on some of the other forums.

Yea, I know it's a long shot. But hey, I gotta ask anyway. Thank you both for the info. I did find some good photos.

If I recall some of the folks at the forum gained rights to the design but could not find an economical shop to make them.

I’d love to find a source, it’s kinda hard to justify a 3axis mill without a real business plan to my wife[emoji6]

What about Hunner Mounts?

What about Hunner Mounts?

I'm familiar with the two other popular styles of mounts. Hunner style which bolts under the factory ones, and the other high clearance fabricated/welded style. I'm particularly interested in the low profile machined style so I was just investigating. I like the idea of one machined plate.

The Tomp mounts are great. He was able to get runs of them made during the recession but as the economy picked up the machine shops couldn't afford the time to make these, at least not at a reasonable price. He also probably made the heaviest package to ever ship in the USPS flat rate shipping boxes. They are heavy!

Hunner makes a great product too and I've been running his front leaf spring protection for a long time. So while you keep an eye out for Tomp mounts maybe consider investing in something like Hunner's product.

Here's another photo of them

That’s a work of art!

They arent impossible. Have a set in my garage

Are you planning to use them?

I've learned a little bit of the history of these. I'm going to launch a task force and investigative committee to see if there is interest and/or feasibility in manufacturing a few sets of these in the 2019 calendar year. Maybe there's some renewed interest.

 

[Bowser-II]

I would be in for sure.

Thanks everybody, for the info and photos.

 

[alrock]

I'm already working with Tomp to see if another run is feasible. Hope to have an answer next week. Minimum 10 sets would be needed.

Stay tuned.

CNC milling is expensive. The plate stock (.750”?) is also very heavy and expensive. Given the use, I think a laser cut and formed (.250”) version would be much cheaper and easier to fab.

Personally, I would abandon the idea of trying to combine the shock mount and spring plate. Instead I would make a simple (cheap) flat spring plate, and then weld-on separate shock mounts to the axle tubes. This is what I do for SOAs...works great. Once you commit to using separate pieces, the spring plate can be made very cheaply from .250” steel. No forming. No milling. Super simple. The shock mounts can be bought for $17...

Another option is to use square u-bolts and flip them, so the ends are pointing upwards. This way there is no spring plate on the bottom of the springs. There also is no threaded ends of the u-bolts hanging down. This would yield even more ground clearance...

This is what I elected to do on my Xterra (been keeping quite on that mild build) when I put some OME rear spring pack in.

It uses a billet aluminum "retainer" to keep everything where it should be:

These are great options to consider, thanks to you guys for sharing.

At the present time, I'm interested in a strictly bolt on option. I have the Hunner style, not currently installed, and the 1/4" thick bent steel/welded/fabricated version style which are installed on my truck. Pros and cons to these different styles.

If I decide to get the welder involved, I'd strongly consider a Spring Over Axle set up. I'm just not ready for that right now.

 

[4speedfunk]

The problem with the spring over is that you can’t do it for less than 4.5” to 5”. So you need a Rancho or SAS in the front to even things out.
Many years ago I did see an H3 for sale in CA, that had a stock IFS front with a very poorly done SOA in the rear. It looked absurd. It was so horrendous that it was made fun of (and that’s why I remember it). Wish I had saved a pic of it. The headlights were probably useless.
You could try “frenching” the springs into the frame or doing some sort of shackle flip to compensate for the SOA but, neither will be easy or simple.

+1 I'd be in for a run if it happens.
