I bet you’re right. My bro-in-law is working in the oil boom up industry in ND and runs Duratracs on his 2010 RAM 3500 crew cab long bed. He claims his last set of dirtytracs lasted 52,000 miles on a heavy Cummins truck albeit the last few months they were definitely onion skins. 50K on a heavy diesel truck running 50% dirt roads is pretty good in my opinion. He is anal about rotations so that probably helps.

I was happy (and surprised) how well the Fierce Attitudes have lasted given the fact the K10 has a Detroit locker in the back and eats tires like crazy. Those tires made one trip to California, two trips to Arizona and 2 trips around Utah and they still look practically like new. I would guess they have close to 10K on them. Very minimal wear and zero cupping.

Well, it’s quite funny actually. Both are running the ORD front HD shackles, ORD sway bar disconnects, el cheapo Superlift 6” lift shocks but the K10 has a set of Superlift 6” soft ride springs while the Burb has a set of 4” Rancho springs that were actually on the K10 when I bought it back in 1996. The funny thing is they are about the same height even though one has 4” springs and the other has 6” springs. The K10 with the 6” Superlift springs rides so much better and flexes like crazy. The burb is pretty stiff and doesn’t flex very well although the newly added weight of the 8.1L did help the ride quality on the burb quite a bit. Also helped with the wondering issue at road speed it has had since I installed the lift springs. The K10 is in dire need of new shocks badly. On the desert trips these shock heat up within the first 20 minutes of off-roading then are like not having shocks at all after that but I blew my whad on the Burb’s engine swap and new tires for the K10 so new shocks for the K10 won’t happen for a while.

Of the two I like the Superlift Softride springs the best. Not sure about shocks but I’ll have a better idea once I start shopping for a set for the K10 later this summer. The Superlift shocks are just nice because they are cheap and work fine for the lighter burb but with the weight of the K10 and type of off-roading it sees, they are not enough shock.
