Hey Team Jeep,

Can I get my 06 5.7 flashed /tuned with the programming for the 08 5.7's that offer more horsepower out of the factory b/c of better tuning?

Thanks Guys

The horsepower for 2008 is exactly the same as 2006 - there was no change.

Is this for Commander or Jeep Wrangler Unlimited?

According to the Jeep Press release for the 08 there is more horsepower and the MDS kicks in sooner, the same was said in 4 wheeler, and car and driver as well. Is this misinformation to push the 08's out?

Offroading was of course taken into account, it is a Jeep after all! As with the WK though, we specified a range of tire sizes for the different models/trim levels, but we dont specifically build a vehicle with the intent to put much larger than stock tires on it without modifications....this is where Mopar and the aftermarket step in to meet the needs of customer who "want a little more" so to speak....

What are the technical stats on the rear axle? What kind of suspenion geometry is it set up with?

[Melhar]

Recently, my son was driving his Commander on a residential street. He was traveling at approx. 12 mph while turning a corner. He was hit near the right rear bumper by a car driving approximately 25 mph. The impact flipped the Commander over 3 times, landing on the passenger side of the vehicle. No airbags deployed. Why was the vehicle so easily flipped, and why no airbags? What should my son do now?

[curleycommander]

Is a Jet chip worth it for the 5.7 and what lift do you guys recommend? (Sorry 2 q's)

There is more MDS operation, but there was not a change to the horsepower rating. We are unaware of any press release that indicated a change in power. Our website correctly indicates that the 5.7 is rated at 330hp/375lb-ft of torque. Unfortunately the calibration from one year is not compatible with another year.

The 4x4 Commander has a C213R (Corporate 8 1/4). The ring gear diameter is 213mm or about 8 3/8". It is a full floating design which means that the axle shaft doesn't carry the weight of the vehicle - it has a unit bearing at the wheel end. The ELSD version with QuadraDrive II has the torque capacity of a locking differential.

The suspension design is a 5-link which includes 4 control arms and a track bar.
