What would be the ideal gear ratio for off-roading in the desert ( no rocking ) for my 06 manual sport.

Currently have 33" tires on D30 & D40. As they came from the previous owner am not sure of the existing Gears.

Why I ask , at times I feel under powered to get over sand dunes where FJ cruisers sail thru.

What else can be done to increase its power ?

It's a balance really. The higher the ratio, the more seat-power you feel via quicker acceleration. But that cuts down your top end (limited to 108 I believe anyways...)
A 4.56 is the general go-to for 33s to get your Jeep close to stock performance. If stock isn't good enough, you'll have to do mighty engine upgrades.
Those FJs have a newer, more powerful engine with a higher redline so more time to stay in a gear.
You could stroke it out to 4.7, some new internal parts along with it. I think gains are in the 70s for BHP and torque. You could get a RIPP supercharger or a Banks turbo. I think again about 70 for gains. Or even an entirely new engine.
Toyotas...hmph.

Oh as for current gears, if it's the Dana 44 (not 40) then you likely have 3.73 gearing, if it's limited slip.
If it's maybe not a 44 and a 35, you are more likely to have 3.07.
Send an email to Jeep with your name and VIN and they can give you a build sheet for free.

It was upgraded to D44 by the previous owner , jeep doesn't have the details.
As its not my DD , i really don't have any highway expectations from it.
Its our weekend toy.

Will changing the header make any difference ?
How to check my gear ratio ?
