4" lift

<< < (8/8)

footman:
so I ordered my lift today.  And I got and email back asking me questions that I need your help with bc i'm clueless, see below.  Plus did you guys have to measure for your CV shaft?



Did you want to Add RE Monotubes to your order for  $250.00 more?
There are a couple upgrades too that are available. Long Travel and Premium. $25 and $40 extra. Let me know if you want to upgrade. If vehicle will be used off road a lot, it is a good idea to at least go up to the Long Travel... Both Upgrades are picture in the Guide I have attached...

 The S spline is a conventional spline stub that will yield a safe, effective and usable stroke of 3”. The X spline is longer than the S spline. The X spline is cut for the full length of the spline stub. This gives a bit more than twice the contact area between the slip yoke and spline stub and a stroke of 4-1/2". This in and of itself will net more than twice the life on these two components.

With the XB configuration, we will use a heavy rubber boot which is banded down with stainless steel banding to seal all of the contaminates out and keep the grease in. The XC configuration uses the same slip yoke & spline stub but instead of using the rubber boot, we drill and tap the slip yoke for a grease fitting and use a dust cap which has convolutions that follow the spline stub for sealing. We consider the XB configuration to be the longest lasting and best value.

He's referring to the shocks here. If you lift your Jeep, it will require longer shocks to get the maximum flex out of the lift. It's not a bad price for a really good set of shocks, however, cheaper shocks are really only about $100 cheaper. Its a personal preference in my opinion.

Somone correct me if I'm wrong, but this refers to the slip joint on the driveshaft between both ends. When your axle flexes, your driveshaft length varies and this slip is where it happens. The salesman is saying its a little more stable and increases the expected life of the driveshaft with the "X spline". The "XB Configuration" he's referring to is the way its lubricated, the XB has a sealing boot that matches the splines on the slip to keep dirt out and it comes with a grease fitting to keep it lubed. If it were me, I'd go with the X spline in the XB configuration...Maintenance on it will be easier and will help it last a longer.

Just my $.02   ;D

Jeeper:
I have the RE 3.5" with RE monotube (long Travel) and they are great. I would spend the $$, and I agree with Seabee about the shaft XB configuration is the way to go.

footman:
how does the RE monotube compare to skyjacker hydros, bilsteins or others

Seabee_BUC:
Not too sure about the ones you mentioned but I just put new Rancho RS5000's on JD's TJ...The ride is soooo nice now...I haven't had them off road yet though. I would imagine the RE ones are a bit better because they are matched to a lift and larger tires. Not that its a defining factor but the RE ones are also like $10-$20 MORE per shock than the Ranchos...
