Isn't it time for a new Radflow group buy?

BDS, ReadyLift, Smaxx... You name it, we know about it here.

I remember standing next to James when he took those pics... I thought we were seeing the last of TBYoda before he rolled off the mountain... Had me a bit nervous, Rob. You young kids and your wheelie shenanigans. Or as the Roadie once called me, "young whippersnapper"

"We can definitely do a group buy on some of our Trailblazer coil-over kits. The standard retail price is $1280.00 for the pair. If we can get 10 sets pre-sold we can do these for $1050.00 per pair. Thanks"

So if people are interested, I would like to purchase a set as early as 1st week of March. Let everyone have time to file taxes or whatever the fuk it takes them to get the funds together, if we get 10 beforehand we can go ahead and pull the trigger.


OK - so are doing this? Let's see if we have 10!!

Bummer - well, looks like I'll be paying full price :) After testing out the winch last week, it's enough weight with the bumper/skids that I need stiffer springs for sure. Might has well get something adjustable and be done!! :excited:

Yea it is a bummer. As far as your springs, you could get a set of moog114's. Thier stiffness is between an 87-88 I've read. They are like $50 on eBay.

Make you own coil over say from a FOA shocks or some other type like this and just pick your spring rate. Would just need to mill top shock mount and the bottom mount that attaching in the yoke. The end of these shocks unscrew and should be pretty easy for metal shop to make the ends. A few of us have talked about it and think you could make a set for about half.

I even have a set of strut mounts I grabbed from the Pull A Part for that reason. Anyone with a lathe and a brain should be able to make the lower mount.

A couple people did that with some other coilovers before Radflo jumped in and made a solution for us, and the ends of their shafts broke. Obviously, the stock setup is the other direction, because the larger bending force is in the middle, where the offset and damper meet, not at the top. I think the only reason the Radflo works and the others didn't is that they use a 5/8" rod and full diameter threads, whereas the other ones used cut down threads. I think I'd also want the aluminum to go up the shaft a little bit, vs. stopping at the base of the threads, for more support. (i.e. a counterbore)

I'm not sure I'm following, although I did see where Roadie had a Icon coilover for awhile and it busted at the bottom.

My idea was simpler, just turn a piece of steel to fit in the lower strut mount, then machine a mount for a "Normal" eyelet on the top (where the bottom of the shock would go). One piece of billet, easy peasy. The upper mount should be pretty easy and straight forward. Finding a coilover that's appropriate might be more difficult.

Then I realized that I would likely outcycle the Tripot pretty easily, and still wouldn't be able to get a front locker, and thusly a SAS with a 3 link seems more worthwhile to me lol.

But, if my idea doesn't seem utterly idiotic, and anyone is interested, I could draw it up in CAD.

You can't do that, though, with the lower strut mount. The lower mount needs to be solid. The joint between the offset that goes around the half shaft and the lower mount of the strut is floating, so the joint needs to be something that can't bend in any direction.

I already have plans scribbled down, it's something I've had sitting on the to do list for I think easily over a year now.
The FOA shock has a .75 shaft, so I assumed it would hold up as well as the radflo shock.
Putting a counter bore on the adapter was kinda a given in my mind cause you wouldn't really want to put all the stress in the threads. Maybe it would be fine, maybe not, wouldn't be a big deal to add the counter bore so it seems silly not to.

The upper mount can be as simple as a piece of plate that bolts to the body in the stock location, with a rod end shock mount welded on. Or a pretty machined piece like the radflos.

If we're talking about a rod ended shock like the foa or radflo, just bolting an adapter onto the rod end would probably amplify any side loading and make the assembly extra long and if you were machining it to fit around the rod end mount of the shock to make it rigid like it needs to be it'd be extra complicated. In my mind it would just be easier to thread the adapter and screw it onto the shock rod. But I may be misunderstanding too LOL


When I was toying with the idea originally I found I could get a lil more angle outta the CV and the balljoints (after the upper was flipped) and the tie rods, but the shock was the limiting factor, I dunno if in practice you can squeeze another .5 inch or a full inch outta it, but there was more available on my vehicle.

Beyond that you're looking at some custom rcv jammies to get a little bit more angle, and considering nobody wants to pay for radflos I can't see many going this route. Especially for the limited gain.

At that point you might as well extend the A arms 3 or 4 inches per side to make the add to the travel gained and to make the custom CVs worthwhile.

Of course you're still stuck with a front diff without a locker and of questionable strength as you get more and more retarded with the setup. At this point you'd have 2-3k in the setup at least and is it worth it? I dunno... I think it's probably the next logical step without going full retard. You could end up with a pretty nifty setup that's probably still fairly reliable on 33s though.


Of course this is how I've ended up where I am though, so you probably shouldn't listen to me or my rational.

Duur, I really hadn't thought of that, that idea would have been a disaster lol.

My logic chain led me down the same path more or less. That's why I decided to go full retard lol.

But, i will say, my Trailblazer, on 32's and lifted the same as everyone else's, does quite well in medium difficulty offroad settings. I mean, I've been to all the offroad parks in Michigan and haven't required any extraction's sticking to the 5-6 out of 10 trails. Ultimately though, the only two ways to get down the trail are traction or momentum, and I don't want to use momentum lol.

I see this thread went down the path of fab'ing our own coilovers (would be very cool btw), but I decided to call Radflo and order up a set!!! :friday:

They said they had enough parts in stock to build a set so they should have mine done in a week!! :excited:

Also, even though we didn't get enough for a group buy discount, they offered them up to me at $1200 + shipping.

Mike Crosby at Radflo also said they will be more than happy to offer anyone here the same discount... but they will just have to wait about 3 weeks.

Thought I would let you guys know!! :thumleft:

I really don't think I am legendary by any means. i just did a crazy jump and luckily didn't brake anything major or die going down the hill to right in the video.
