HELP... Building my 08 JK

After saving $$$ for the past year and a half. I am finally modifying my Jeep, and I need some help. I am not mechanically inclined so bare with me.

I have a 2008 Wrangler X with the S package which added options including the 17 inch alloy wheels.

To date, this is what I have ordered in the past week:

Rugged Ridge Modular XHD front and rear bumper in powder coat black
Rugged Ridge XHD rear tire rack
Rugged Ridge 4 inch tubular side steps
Front skid plate
Rough Country 3.25 inch suspension lift kit
Rough Country Perf. Dual Stabilizer
1.5 inch wheel spacers to accomodate running my stock rims with 35 inch tires

Most of these things have either arrived in the past few days or are hopefully being shipped soon, but I have some questions.

I believe my gear ratio is 3.73. I plan to run 35s which will be a 3 inch increase over the stock 32s. Do I need to start considering upgrading my gear ratio to 4.10 or higher to accomodate the 35s? I don't want my JK to be a slug on the road. It is my only vehicle and I will be using it mostly for regular highway driving.

:rolleyes: I'm not ignoring you Tpr, but you're driving a 2dr and spec's like 2.5" Vs 3.25" are better handled by JB or HD

It's pretty accepted on the 4dr's that 2.5 " lift has a 99.9% NIL effect, on ANYTHING other than wheelwell size, but I'm clueless on your jeep

:rofl::rofl: JIMBO

You'll have to find out if the shocks will still be the right length. Other than that though, the less you lift it, the fewer knocked-over dominoes there are.
You shouldn't have to mess with driveshafts with 2.5" at least.

Well I pulled the trigger on 305/70R17 tires...which transfer out to be 33.8 inches. I think I will leave out the .75 coil spacers too and just go with the 2.5 inch lift. The added weight from the XHD front and rear bumper and XHD tire rack will probably make the 305/70R17's look faily proportionate.

I am going to put off regearing as long as possible. Unless I hit the lottery

Bear in mind that those springs will sag a bit after a few weeks.

Have you read all the requirements for anything over 2.5" lift? You can put on a Tereflex 2.5" coil lift and run up to 35" tires. Over 2.5 and you will need drive shafts plus you will have may have many other handling and alignment problems that a simple lift does not address.
