Tom, I think I am missing something here. I am not challenging you here, I just am trying to understand.
If someone adds 2.5" Daystar lift , all it does is make the strut 2.5" taller than original, thus moving the suspension down 2.5" lower in the control arm travel (IE raises the Jeep). Why is this ******* upper control arms? I do understand this solution still has factory suspension travel of X inches, so you should add bump stops that are 2.5" longer as well to prevent over compression of the spring.
Now I have read that adding a EMU spring and there strut strut, that also sits the vehicle 2.5" higher than stock is not going to be ******* the upper control arms and does not require any taller bump stops?
But this solution will still lower the suspension 2.5" into its Travel.
Does the different strut used with the EMU end up giving you 2.5" additional travel over that of the stock spring/strut?
If this is the case, I can see why you would NOT need different bump stops on front. But if it is not 2.5" of additional travel, why does the EMU strut not need replacement bump stops? does it rely on the spring going into total compression to act as a bump stop?
Also if your actual are adding 2.5" of travel to the suspension, allowing the suspension to compress back to the max factory compression, your over size tires are going to hit inside body in this compressed state correct?
Thanks
CLASS NUMBER 9,324 BEGINS AGAIN
TOPIC TODAY SPACER LIFTS AND WHY THEY JUST PLAIN SUCK ( AGAIN )
FEW THINGS TO THINK OVER test on Friday
As we all know spacer lifts compress the spring which pushes the spring up to give lift.
Now they do not increase travel and is now stretching your factory shocks to the limit.
Add in that factory shocks are not very stron, can be worn out etc then they do little at all in controlling the bouncing of the springs.
As we know factory springs and shocks we border line even when new.
So any changes at all to the front suspension and the shocks simply can not and will not do their intended job.
NOW TO THE SPACER
You only have so much room in the actual coilover themselves , so with the stock springs / shock combo it did its job. ADDING a 2.5 inch spacer now compresses that spring 2.5 inches. They were designed to operate in say a 9 inch space but now only have a 6.5 inch area in which to compress etc when going down the road . VERY LIMITED!
THE RESULT is that the coil winding spacing will be in turn less and end up being stacked coils on almost every bump. When a coil become compressed that much , then it is known being stacked , coil upon coil
So less suspension travel , worn weak springs and shocks ( have actually seen a 2.5 inch spacer lift installed that gave 3/4 inch over new height . Springs were sagged that bad but he was telling everyone it rode great, which you could clearly see did not.
So in the end, coils / shocks bad which in turn makes every front suspension work harder/ parts wear out faster , you go boom at 65 MPH and wreck your family.
All for today's class feel free to comment / argue / tell me I'm an idiot heard it all since I first went to Brake/Suspension/ Alignment school back in 1973 :happy175::happy175::happy175:
