Looking for thoughts on rough ride
Looking for thoughts on rough ride Well after all the hard suspension work I've done, I'm looking for ideas on what the main culprit is to change out to help with ride comfort. Only reason is I'm giving my daily driver ranger to my fiances son for 16th bday so driving this daily for a bit. I'll list what mods I've got
LT1 pro kit springs- thinking this is it
KYB adjustables all the way around
Subrframe connectors bolt in
double adjustable panhard bar
Founders On-Car Adjustable Lower Control Arms Poly/Rod
Founders On Car Adjustable Panhard Rod Bar Rod/Rod Style
Founders Lower Control Arms Relocation Brackets
BMR trans mount adj torque arm
Since dropping with the springs and now with LT headers and Texas speed Y I'm scraping often. So i'm looking to maybe go back to factory springs to help comfort if this seems to be culprit.
Don't get me wrong I love the drive but getting older and the fact that fiancé refuses to ride in it lol, need to make some changes. Besides heard these springs are bad for launch anyways.
Hook me up with some thoughts and thanks in advance.

LT1 prokit is not "bad", but there are better out there. All else equal stock springs are going to ride the best compared to lowering springs.
your KYB's are not helping the cause, as they adjust compression with rebound on the same ****, so the higher you go the more compression you are dialing up, other single adjustable shocks are not like that.
And your rear LCA's are not helping either, go back to the stock ones and see if thats any better.
Keep tire pressure around 30psi ideally as well.

Ok ty for the reply... I will probably pick up some regular LCA's from Founders... Won't need the adjustables or anything...Going back to factory springs too...Shocks are going to have to ride it out since I don't have that much to spare atm...Surely better than the factory decarbons I pulled off...

^^This....I chased a noisy rough ride and it turned out being the "aftermarket" LCA's. I braced the stockers and reinstalled. Quiet as a mouse and dead hooks/no wheel hop using LCA relocation brackets on lowest hole. Try it.
wow back to stockers for LCA's huh? I'll shop around for some don't think I kept the originals... I'm sure I'll go back to stock springs though since its too low for y-pipe and I get really annoyed Scraping when I do by accident. I loved the look before headers but now I love the headers more lol... I'm going to try and dig up some parts if I kept them but may be back tomorrow looking for parts...

Either that ... or try to find some rubber bushings that will fit the tubular LCAs in place of the poly. If you find something ... let me know ... I would love to put my Founders LCAs back on it ... if I could find the right size rubber in place of the poly.

Verdad Gallardo And I just realized in my original post I put LT1 prokit... yea its the LS1 prokit... is that going to make a dramatic difference in ride from you gurus opinion? I heard the LS1 prokit was dramatically different in terms of quality...
FYI, the Founders LCAs with the 3 Piece Poly Joints on both ends would be as quiet as stock.

LS1 Prokit has a softer spring rates.
The LS1 Prokit has a 400 lb.in. front and, 80-137 lb.in. rear spring rates.
The LT1 Prokit has a 366-600 lb.in front, and 94-160 lb.in. rear spring rates.

I have actually been looking at those today and comparing...I don't want to lose too much performance but getting older so these od ends gotta go... Most people could handle the noise nope not me...Thanks for the reply I am ordering right now... Still undecided on springs.... thinking I need the additional clearance for headers now anyways
Stock LCA for the win!!! I had a jittery knocking ride with roto joints. I switched back to the stock ones and it is quiet and smooth. I am pretty low also. It honestly rides better than stock just a little more firm.
Alright so I just go back from the muffler shop.. Had a new muffler installed since flowmaster is beyond crap with headers and ORY. Also had them Do some tucking on y-pipe and a little fabbing and now its almost factory clearance.... So prolly stick with the springs for a bit.. Got some different LCA's coming that aren't rod end... All in all rdy to drive it a bit... It's at shop for about a week getting AC completely worked over so I'll update when I can.
got the new 3 piece poly from Founders installed and gotta say, loving the ride now! No more noise from rod end LCA's. Perfect for my daily driver now. Thanks for the recommendation 99Bluz28!

OP, Your problem (as far as lower control arms go) is the rod end, they aren't practical for a street car and are known to cause harsh/noisy rides.

That's potentially part of your problem. The LS1 engine is somewhat lighter than the iron-block LT1, so the additional weight of the LT1 has you sitting lower, with the LS1 springs in place...

I'm debating taking my umi tubular non adjustable poly rear lca's out and swapping the stock rear control arms with rubber bushings back in. Even with new Bilsteins on stock springs the rear end feels so harsh over less than perfect pavement. Also considering removing my sub frame connectors. I daily drive mine and am starting to hate it because of the rough ride. Any feedback from anyone who has gone back to stock rear lcas/removed subframe connectors?
