It's not so much that the struts are the limiting factor. CV angle is THE limiting factor. That's why the big top spacer only lifts aren't good for the 4x4 trucks. Put a big enough top spacer on the truck, I think .75" thick is the max, and your CV's will lock up at full droop. To be more specific, the stock struts can exceed the other limits of the front suspension/drive train already.


I know the cv's are the limiting factor, been contacting companies to get a set of high angle cv's made which should allow up to 44* with no problems.

Now your question makes sense. My apologies.

Still poking around with other companies, I thought I could try and piece something together but the 930 joint i was going to use doesn't plunge like a normal cv shaft does. That kind of blew my whole idea up and back to the drawing board for ideas.

hey guys i dont know if anyone has asked this yet or i may have not seen it but i was wondering if you can mix these coilovers with a lift kit, such as the lift meister 3" suspension lift? or do those top spacers of the coil prohibit it?

As I understand it, Radflow can build the coil over to meet your lift needs, why would you add a spacer?
Anything much over 3-4 inches of suspension lift and you run into binding issues with front CV axle.

No need to mix them with a lift. You can get them any length you want (I went 1/2" longer than stock), and any spring rate you want, and the springs are adjustable for ride height, so you can be either stock or 3" lifted or whatever you want with them.

Thats good to hear! In the future i would like to purchase this because of the look and performance of a coilover over an aftermarket strut. The question is now what would be the right option to order with my lift kit?

The only lift kit you will need is for the rear... The coilovers will take care of the front

Coilovers provide the lift and you can adjust the height where you want it. If you want to keep your lift kit you can't do coilovers

Why would you want both? Do you not understand that the coil over is a better replacement for our lift kits and render the lift as totally unneeded.
I hate to advocate weird chemicals, alcohol, violence or insanity to anyone...but
they've always worked for me.

Coilovers replace a lift, you don't need a lift kit if you have coilovers... Not sure why you would want both

I've had to put this on the back burner for a while. RCV can do it, but I was also going to contact http://www.driveshaftshop.com, and then a local shop called Ontario Engine and Machine http://www.ontarioengine.com/ . The last one built a set of custom cv's for a friends RWD Grand Prix, plus they are only an hour away from me i could just leave them my truck.

I've accrued a lot of debt living paycheck to paycheck for the past 4 years, now I have a new job putting me into the positive side of things, I'm trying to knock my debts down first before I spend frivolously. I don't want to seem un interested to these guys by not having the cash up front and wasting their time, as these will need to be custom. Even if I only need to have some machined flanges made to adapt parts, I can assemble the shafts myself. I feel RCV is just overkill with their race quality shafts, I'm not planning on bouncing off rocks at full throttle.

Ultimately this is what we need...but with our style input shaft.

Interesting, I kind of have the ability to pay to play in this area. However I don't plan on going beyond my current ride height, and I'm mostly interested in improving things for long term durability. I don't want broken CV axles on the trail but I don't have plans of stuffing 36s or 37's under my car either. I'm happy with the 35's. But I'm just now getting into readying about improving the front weak points and I'm very interested in improving the IFS. No one has pushed the limits there.
