Any interest in 4wd front coilovers to replace tbars?

So if you know the ride height,(top mount to the bottom mount) what is the number that needs to be subtracted to get the proper shock length? I would want to go with the stud mount on the top.

I'm pretty sure you don't have to subtract anything if you using the stud mount. The 1.5 inch subtraction from your shock was if you were using the adaptor from stud to eyelet mount.

But his new lower mount moves the shock mount up, so the shock need to be shorter by the same amount. also if you use his upper mounting bracket it moves the mount lower so again, you need to subtract that amount. I'm sure Atomic will chime in and set us straight.

I guess what I need to know is how far up is the lower shock mount moved? Going by the pictures it looks to be 2" why I want to know is if I go this route, I can measure my setup as it is now, do the subtractions for the mounts and get the new length for the coil overs. I don't want to take things apart more times than I need too. I can order my shocks and springs and be very close the first time.

The lower bracket moves the shock up 1.75" and the top bracket moves the surface down about 1/2". So if you measure from the bottom to the top and use the stud mount subtract (1.75+.5=2.25") 2.25" from that number to give you your shock length. If you use the procomp shock adapter, that piece shortens the distance 1.5"

A guy on PT just finished doing this swap on his RCSB and this is what he had to say about it:

Well, first off, I need an alignment bad.

I think it's silly how good the front suspension is compared to the rear. I was playing with it off camber a bit, ramping over the bumps on the edge of my parents driveway. It just absorbs it. I can jump up and down on the front bumper and there's more travel than it's ever had. I think the liner way a coil spring works is better than the twisting way a torsion bar works.

Like I said, I need to get it aligned. When the ride height is exactly where I want it, I'll drill the lower a-arms and install some bumpstops. I can't really do that until I'm 100% sure the height is correct. I may need to trim the bumpstops I bought.

The sale im having ends on Tuesday!

Do you have a link to it. Would love to read it. (found it)

Looks like a problem w/ the bushing.

 

[Bomba02]

I wonder if he has drop spindles. Been looking for the article on PT. could one of you post the link please. It's gotta be way better then the T-bars. Regardless of the sale I will be purchasing a set sometime!

Yes he does. McGaughy's drop spindles. Read his thread, unless he changed them out, but did not see a mention of it.

Im with you, its got to give a better feel driving.

Thanks man. Looks like it would be a go for drop spindles. I wouldn't be to worried about the top bushing they make washer that cup them as well. Could use those instead of the flat fender washer which would work fine to. Have to let him get some miles on it and ask him how its holding up and feels.

He is the first one to finish an installation with the stud top I think, so its normal to run into minor issues like that. Similar to the issue I ran into with the included plastic bushings.

Here is his build thread for anyone looking, http://www.performancetrucks.net/fo...hevy-silverado-project-charlie-murphy-489579/

You must of edited your OP i guess, b/c on it, you suggest getting a the better bushing for the stud mount. Unless that is the one he has, do not remember at the time.
Either way, im keeping an eye on his thread. He is very hands on.

Glad you brought this over here Atomic, thanks.

 

[Atomic]

Yes I suggested that based on feedback from him. It looks like in addition to the better bushing you want to use some sort of large fender washer or williams washer to better distribute the weight.

No problem, let me know when you want to try them out for yourself!

I am going to try them for sure. After the holidays and having a Tahoe full of people, i have to do something to fix the ride. Front and rear shocks. Currently the shocks are way to long and have about 2" of rebound if that.
Thinking adjustable shocks for the rear and your kit for the front w/ adjustable shocks. But confused on what springs & what size shocks for my application. As taking them all off and measuring is not going to be the easiest, but assuming that is the best way to order the correct shocks.

Just awaiting someone on GMFS to get back with me other wise i will be ordering from you soon.

I was on the RideTech site tonight, and there airbag/shock setup for the Yukon mounts to the stock upper shock mount with no extra reinforcing bracket. either the upper OEM mounts are very strong or, they haven't had any issues yet.

Amongst my research there are a couple people that have no reinforcement on the upper perch. Sure atomic can chime in on his experience.
Looks like they use the Eye to Stud Adapter to mount to the upper, which to me is not a reinforcement, but not straight to frame either. So that could help.

Interesting bottom bracket they use.

Here is ridetech coil overs on a truck. Wonder what mount is on the top of this one?

I tgink this is the right solution for the upper wear you could face

Shocks are sized based on the ride height you want. If you can measure from the lower shock bolt on the LCA to the top of the shock hoop I can tell you about what size you need. Springs are based on the shock used and the weight of the vehicle. You can adjust the height somewhat by increasing or decreasing preload on the spring.

I was on the RideTech site tonight, and there airbag/shock setup for the Yukon mounts to the stock upper shock mount with no extra reinforcing bracket. either the upper OEM mounts are very strong or, they haven't had any issues yet.

Both most like, but how much do you trust a mount that was designed for shock only and not to carry the full weight?

I have seen plenty of people that do nut use any type of upper reinforcement, but how much do you trust that part? They all seem hesitant about it, which is why I made the upper mounts anyway. You dont have to use my uppers if you want to switch to coilovers.

The LCA for the 2wds are much different than the 4wds.

 

[Atomic]

I believe that upper mount is specific to ridetech coilovers, which are fine by all means, but I designed the top mounts with qa1s in mind. If the ridetech style will work with my brackets I dont know.

Sale ends tomorrow at midnight!

I think that upper is ridetech only. Cant find much else on it.

I will try to measure what you stated and get back with you.

This may be a question most will know, but i do not and if i dont know something i ask regardless of how simple it may be. One can always learn, but what is "Preload" I see that a lot searching springs? Could someone simplify that.

Hey guys, I have been making these for a while but wanted to see if there was any interest on this forum for this sort of thing. Its a bolt on kit that allows you to use aftermarket coilover shocks instead of the factory torsion bars on 4wd gmt800 trucks/suvs.

I did this on my truck (99 silverado) and have about 1000 miles on it and it works great. I have mine set up for drag racing so the CVs are perfectly level, but the same idea will work if you want to go lower or higher. You can get around a 4" drop with the factory spindle and LCA, or a 3-4" lift in front with the factory hardware. And the best part is you have dozens of spring rates and shocks to choose from so you can have your truck ride exactly how you want it. Weight savings is about 40lbs but that wasnt really the point of me making these.

I am at work so I cant post pictures, but they are fully welded 3/8" steel with 1/2" grade 8 hardware and powdercoated flat black. I sell the seperate lower bracket (which you need), and an upper bracket that reinforces the shock hoop (optional). Both together are $350 and either seperate is $200. The whole swap can be done for around $700-800 depending on what parts you use (brands of shocks/springs). I only sell the brackets.

Anyway, let me know if there is any interest and I will post up my full write up. I sell these on a couple other forums, mainly GMFS and performancetrucks.net.

I am new to this forum, but not to others, im a supermod on PT with close to 10k posts, and have almost 7k on FSC and about 1k on gmfs.

Thanks

glad to see you on this forum, this is "sleeperlqx" from PT. And this was actually one of my questions I had for you besides my turbo stuff, cause Im going with the brackets and this kit possibly for better handling.
