Need some advise ... looking at purchasing a 2006 QC 4x4 and am wondering if I should be looking for one with LSD & ESP? Is the LSD (Anti-Spin Differental) a good factory option or are they trouble? Is a aftermarket LSD a better way to go? Also, is ESP worth it? Can you turn ESP off if the truck comes equiped with it?

I'm not a big off road person but I do live in Canada where snow is on the ground atleast 5 months of the year and I do take my truck on the frozen lakes to do ice fishing. I want somethingthatwill notget mestuck and make me hang my head in shame.

 

I would recommend getting an aftermarket lsd like an auburn.

 

I realize a after market LSD would be better, but is the stock LSD adequate? Have others experienced any problems with it? What would the cost be to change or add a aftermarket LSD?

 

Yes there are tons of problems with the mopar limited slip. C-clips break in them all the time then what happens most often is it comes apart and your rear end is trashed. Get one with an open diff and get an auburn limited slip. I have a mopar posi in my 98 ram and an auburn in my 06 and the auburn grips MUCH better. I have instant traction and the mopar unit have never engaged right from the start, it always took like 2 feet to engage.

 

I've read in other posts that the c-clip issue has been resolved in the 06 and 07's. Is this true?

 

The stock LSD is the Dana TrackLoc and is a $405 CDN option on my truck. As far as factory LSDs go, this is one of the better ones in that it uses twin clutch packs with a moderate amount of load. Basically, this means that it provides a good middle ground between off road and on the highway performance.

The Auburn is a nice unit that uses a single clutch pack attached to the housing. Basically, this means that it engages that much faster than the Dana; however, the load setting may have something to do with that as well. Load is how much slip the gears will allow before shifting the torque to the other wheel. Although the Auburns are considered pretty reliable, in theory if the clutch pack goes (which is by far the most likely point of failure) then you have to replace the whole differential because it bolts dirrectly onto the casing. An after market install of an LSD can run 2 or 3 times the price of a factory option, mostly for the labor.

Depending on your application, you may also consider going with a viscous diff. This type of LSD uses a fluid that reacts to heat generated by wheel slippage to lock the wheels. There are a number of advantages to a viscous LSD, mainly due to the simplicity of the design and its progressive engagement. This type of LSD is usually associated with rally racing.

 

Thanks canram for the info. So I guess your saying that the stock LSD is not all that bad. Does anyone know if the C-clip issue was resolved in the 06 model year?
