Coil springs

[Stocksuspension66]

Truck flexes pretty good. That is basically what I’m trying to achieve. I’m on d1 seats in the back but might switch back to d2 so it can seat the spring better. Are you retaining the springs on the top or bottom in the rear?

 

[discostew]

I do the bottom

I retain the top in the rear. That keeps the spring straight up and down. Makes the spring reseat easier.

I ran retained uppers in the rear and QT short pointy cones at the bottom. Always reseated, but I also had wedge spacers under the spring seat to make them parallel with the upper seat.

 

[Stocksuspension66]

nice flex fisheh. I retained the rear uppers and coned the bottoms. Which wedge are you using?

 

[robertf]

I do top and bottom

I thought about that as well but wondered about articulation.

4" solid round aluminum cut into wedges and drilled. DIY.

I think I’m going to have explore that option

So who is preferred in the driveshaft department. I contacted Tom Woods and was quoted 625 for a front multiple Cardan driveshaft. Seemed a bit stiff but if that’s what it cost then that’s what I pay.

 

[robertf]

Do you need multiple cardan?

Well. Being that the truck was vibe free at 3 inches and stock front radius arms. 6 degree caster arms installed then driven. Vibration at 40mph was noticed. Additional lift has been installed and vibration is still present. Pinion angle has been changed due to radius arms. Drive shaft is an aftermarket but newer. A few guys have also mentioned they are using a multiple Cardan drive shaft at +4 lift. Vendor of radius arms also mentioned it might be necessary. During inspection definitely noticed the pinion take a dive. Used an angle finder to confirm angle of pinion, shaft, and tbox. I am aware that the multiple Cardan is a “band aid” but optimistic. Tom Woods mentioned possible high speed vibration due to mass. As of right now I guess I’m going with Tom Woods but will contact a few other driveshaft guys for more info

I have a Tom Woods on a 4"+ lift with the single Cardan front and rear and don't experience any vibration. I have caster corrected radius arms in the front.
You may not need a multiple joint drive shaft, just a better one.

Did you try GBR? If memory serves I paid $450 for a front dbl cardon.

 

[robertf]

Mine seems ok with regular tw cv and 5” springs with rte arms, but its high pinion diff so doesnt exactly apply here

I will submit my measurements to Tom Woods and a few other driveshaft shops and go based on there expertise. Trust me, if I could stay conventional double Cardan I will. The driveshaft I have on looks like an amazon replacement. Came with the truck. Definitely not top tier but is vibe free under standard geometry.

I did check out gbr’s website. I will contact them. It took all of 10 seconds for Tom Woods to tell me I need a multiple Cardan drive shaft that is 625 and will not rid the vibrations. So, yeah. I will be contacting a few d-shaft shops.
