i just installed a PC 6" lift on my 05. the front sits a tad higher than the rear as i have the Pro 4 x Coilovers in the front. i have the 3" rear blocks that came with the PC kit. i put Bilestine 5125's 2-4" as well. i have my 1.5inch rear blocks from my mini lift left over can i stack them on the 3"pc block? ill have enough u-bolt to bo so but is it safe? will it work with the shocks?

I don't know about the shocks, but stacking blocks is a BAD idea...If you need more lift, look into a Deaver Mini-Pak....Not only lift, but added performance...

stacking block not only will cause axle wrap, which is an easy fix, but the will twist. get you a 5" block, mini-pack, add-a-leaf

or use fabtech's 4 inch block from prg. I asked greg about stackin blocks, he said the same things they said^^^^ so its not recommended. taller block, or a spring pack is your best bet. you should post pictures of your truck!

ok ya i know about stacking front spacers. i was just sondering. thanks everyone! ill post pics soon. im getting the rocker pannels rock guarded tomorrow and need to install new mud flaps and get an amp for my subs then ill post pics when shes "kinda" finished. haha

stacking leveling kits dont do anything wrong if done with the correct kits. all it does it cause your uca to hit your coil bucket at full droop. i have a leveling kit stacked on mine and has been for oh 40k miles or so and not 1 issue. stacking prg or ncd kits NO. stacking polyurethane kits wont hurt a thing

People stack leveling kits?......How Pep Boys can you get?....

Sorry, if you're stacking level kits, you're a tard...plain and simple...

really from the people that know so much about lifting titans? if you run a polyurethane spacer like a daystar, then you can stack them cause they go on top of the spring not between the coil bucket and top hat! also it dont matter. like a ball joint spacer is bad also but people are running them on their titans! yamatitan has a 3/4" ball joint spacer from his uca to spindle. this forum never gets old. some kits CAN BE STACKED! SOME KITS CAN NOT BE STACKED! but what do i know, i dont sell lifts, work on trucks, own a 4wd company, have a heavily modded titan, or know anything about suspension at all! im just another dip**** with a lifted T! lmao

Read and understand a little deeper...

I'm assuming your referring to a plastic spacer bolted on top of the front shock assembly, and you still think it's a good idea to bolt ANOTHER one to it?....There's a reason you can't buy one spacer the same thickness as both...it's poor engineering....

like a ball joint spacer is bad also but people are running them on their titans! yamatitan has a 3/4" ball joint spacer from his uca to spindle.
Is that so his UCA doesn't hit anything at full droop?...But that's not a "stacked spacer"....is it?....Does he also have a lift spindle?...The only ball joint spacers I've seen are for bolt in upper ball joints(actually riveted from the factory) and many of those have issues with the ball joint running out of travel...Does anyone have a picture of this type of ball joint spacer?...

but what do i know, i dont sell lifts, work on trucks, own a 4wd company, have a heavily modded titan, or know anything about suspension at all! im just another dip**** with a lifted T! lmao
No, I don't what you do or know, BUT I do know what I know....

1) Just because some people have done poorly designed and executed lift kits doesn't mean they know a dang thing at all...And I've fixed more "professionally installed" kits then I can re-call...all from shops in the business for years and all who claim to be suspension experts...:ftard:

2) Because you or someone else has spent a lot time "modding" their truck doesn't automatically make that person an expert in engineering someone else's suspension...

3) Just because you ( not really picking on "you"...) can lift something doesn't mean it has anything to do with performance....and many times I hear "I don't care about performance, it's just going to be for around town..."...and the real difference between lift at any cost (read stacking spacers) and performance is design & engineering...

4) My favorite part..ME!....I don't claim to know it all, but I've been in the automotive trade for over 35 years ( spent some years in the Aviation field and even have a FAA Certification to prove it...) and it has ALWAYS been about performance....design...and engineering...I don't know how to take a truck and slam it to the ground with "bags n' dubs"...nor do I know how to take a great sports car and lift it to run 40 wheels...BUT I do know how to take a vehicle and make closer to it's true potential in the performance direction....

Hell haven't even got to "Loufish"...the racing years...:)

BTW...I hope you don't think stacking rear blocks is "alright" because others have done so...

Last but not least....let me share a few photos of a guy who thought he really knew what he was doing...

well the welding work definetly isnt the best to hold up to the suspension that is for dang sure, but the idea is correct IF the correct material is used, the geometry is symetrical, and true. the right idea(so to speak) but piss poor design by that guy. i mean people get 11" out of a 6" lift kit all the time! piss poor engenering on their part? cause titanup your bf had i think it was 10 or 11" on the front from "custom" work done! so i mean just cause things can be done that the application isnt designed for does not make them engenering flaws by the people that do them.

no stacking rear blocks is a BAD idea and i said that in my first post!

polyurethane leveling kits like the DAYSTAR go between the spring and the top hat of the spring. you compress the smaller, put the polyurethane spacer in and release the spring! so on that application you can add as many as you want! just going to make the ride stiffer, and at some poing will have the spring compressed so far it will not add anymore lift. not saying it is the way to do a lift by anymeans, but am saying certain leveling kits can be stacked if so desired!

Beautiful welds.
...To behold....

Have you seen the spacers YamaTitan is running on his UCA's?...Is he running lift spindles with a longer upper bolt with a spacer?...
 
#22 ·
He posted that he now uses a different, shorter spacer:
Thanks for the pic...That's what I had in my mind...If he had run a tapered spacer, wider at the bottom where it sits on the spindle, it would have been much stronger...

wow this thread got very angry very quickly. Its just a question about stackin rear blocks. and it was answered like 5 times lol. But thats why i love this forum. I'm glad loufish kept his professionalism and explained it all, you other people just make me laugh though.

If I recall correctly, PRG sells a spacer specifically designed to bolt up between the coil bucket and coilover (for added lift). What is the difference between the spacer used to level the front end and the one for added lift? I dont have any interest in adding to an argument, rather I'd like to hear an expert opinion on this...

I've got the PC kit too and was looking to get a few more inches all the way around.

If I go with a deaver pack what shocks should I be running in the rear, the bilstein's say they're good up to like 5 inches. Will that be enough?

Are coilovers the only way to add a little more height in the front?

This is more about semantics..."Level Kits" for the front of the Titan are simply a minor lift kit. The term "Level" imply's a minor lift to bring up the front just enough to level the vehicle height front and rear. Most "Lift kits" raise both the front and rear, although most of the time not the same amount...

Another term used now is "Performance Kit" which usually lifts the vehicle some what, but is more focused on improving the suspensions ability to handle more speed, ride better, and even rock climb better depending on the application...

Hey! You side-stepped my question! lol... Let me rephrase... Someone suggested that they were succesful in stacking a poly level spacer with a bracket lift coilover (or bracket lift spacer, I'm not sure which). You suggested that he was, uuhhmm, "a tard" for having done such a thing. We know that PRG makes a spacer to be used in conjunction with an extended length coilover. So my question is, what is the difference between the two spacers, semantics aside?
