2012 Jeep Wrangler: How RTI Compares To A 4-Door Rubicon
March 24, 2012
Our 2012 Jeep Wrangler is a of course a short wheelbase 2-door model, and we've run it up the RTI ramp in many configurations. But how does a long-wheelbase 4-door compare?
I recently got my hands on a Wrangler Unlimited. It's a Rubicon, so it's equipped with a factory front stabilizer bar disconnect mechanism.
A word about the color: It's Dozer Clearcoat, a.k.a. bright orange. It may look like some kind of white-to-orange fade, but that's just my point-and-shoot and the overhead skylight butting heads.
The Electronic Stabilizer Bar Disconnect acts as a bridge between the two halves of a stabilizer bar that has been split in two. It's one of the off-road features you get when you buy a Rubicon. I have my 18mm wrenches, Rubicon owners have a switch on the dash.
Stabilizer bar connected. Wheel lift = 20.56" Distance up ramp = 60.12"
RTI = 518
Stabilizer bar disconnected. Wheel lift = 27.25" Distance up ramp = 79.67"
RTI = 687
|Vehicle Configuration||Wheel Lift||Ramp Climb||Wheelbase||RTI|
|Wrangler Sport, BFG, stab off||26.75||78.21||95.4||820|
|Wrangler Unlimited Rubicon, stab off||27.25||79.67||116.0||687|
|Wrangler Sport, BFG, stab on||20.44||59.76||95.4||626|
|Wrangler Unlimited Rubicon, stab on||20.56||60.12||116.0||518|
This chart compares the 4-door Wrangler Unlimited Rubicon with our 2-door Wrangler when it still had its stock suspension but after we fitted similar BFG tires. The wheel lift is virtually the same in both conditions, but the 4-door's longer wheelbase does a number on its RTI value. Both vehicles gain about 7 inches of lift once the stabilizer bar is out of the picture.
|Year||Make/Model||Wheel Lift||Ramp Climb||Wheelbase||RTI|
|2012||Wrangler Unlimited Rubicon, off||27.25||79.67||116.0||687|
|2010||Toyota Land Cruiser||24.81||72.55||112.2||647|
|2012||Jeep Wrangler Sport||18.31||53.54||95.4||561|
|2011||Lexus GX 460||20.19||59.02||109.8||538|
|2012||Wrangler Unlimited Rubicon, on||20.56||60.12||116.0||518|
|2011||Nissan Juke SL AWD||8.75||25.58||99.6||257|
The Wrangler Unlimited Rubicon tops our list of stock vehicles if we focus on the RTI number measured with the stabilizer bar disconnected. We can do that because it's a factory-installed stabilizer bar disconnect system. The Toyota and Lexus SUVs have a factory stabilizer bar disconnect systems too, but their KDSS system is automatic so they have just one RTI value.
