Ok heres the numbers
Current Rear Upper CA 19 inches TF max 19 1/4
Current lowers CA 20 1/4 inches. TF max 22 1/16
I have already have Frameside Trackbar brace to weld and relocate and lower spring perches 3 inch length extended
Upper rear shocks already relocated back
My question Is to push farther back 2 inches to hit the 100" wheelbase mark I'm thinking of buying TF Upper LongArms which start at 21 inch
Run upper LongArm and lower short arms
Humm thinking

 

Anyone ever come across something like this

 

I must be the first

 

Ok so I looked up specs to just change out my rear upper to a LongArm and the min is 19 11/16 and my current rear upper is 19
The rear upper max length is 21 inches.
I'm thinking of installing just rear upper long arms and lengthening out my rear lowers from the current 20 1/4 to the max length of 22 1/16
This should push my rear axle back just a 1/8 shy of 2 inches with a total of 99 3/4 - 100 inch short arm stretch
Of course if you read the previous posts I already have a Frameside Trackbar relocated ( cut stock off and weld on new) also I have rear spring 3 inch relocate forward weld on rearend and rear shock relocated !!
Rear DS needs to be relengthen after control arms installed
Also bumpstop pads moved!!!

 

I would love some pics of this when you get working on it.

 

Yeah I sure will get done pics posted!!!

 

Still considering this build but been put on backburner. I've come to realize to put a rear coil over system at the same time as stretch so I'm waiting a bit . I did however buy a set of 39's to squeeze under my jeep

 

To make life easy check out the Rock Krawler stretch systems.

They have an 8" stretch as well as a 3" stretch now.

PM us for more details.

 

Nope sorry talked to them many a time and that's not the route I want to take.
I don't want to weld on +3 pads , or mess with coils in rear anymore. If I goto a rear coil over its the ticket for what I want to do.
That way I have more options as I build it like starting short arm stretch and later on install long- arms if I want to.

 

bubba, you got the right idea. call tf and ask them regarding the shank lengths. i went through this or deal recently and the cost to do all this because i cant weld verses the little performance benefit wasn't worth it.

the teraflex rear upper control arms from their flex kit has about 3 1/2" of shank before it runs out.

teraflex rear lower control arms have about 5" of shank before they run out.

i'd buy the rear upper long arms and run their flex arms for the rear lowers.

youre absolutely right, though.

you'll need to lengthen the rear drive shaft

you'll need to cut off the rear trackbar frame side bracket

remove and re weld new coil perches

remove bump stops

remove rear sway bar

and you will have to re weld on the upper coil mounts as they will need to be relocated.


for me........... the benefits to doing this stretch was just not cost efficient for the minimal gain.

this is pics from when i pushed the axle back a few inches. big issues
