We just got back from a month long trip to the Southwest and the ride on mild washboards was very poor. I'm looking into rear end suspension upgrade/replacement options.
The wheel/tire setup of Rickson 20" wheels and Continental MPT81s were great. We are using the Fabtech 6" Radius Arm/4.0 Coilover Kit (w/ front and rear DirtLogic shocks). I wanted to go with 3-4" lift, but none was available at the time so we opted with a 6" lift. The front end of the Fabtech kit has been good. The rear portion of the kit (which uses the stock springs, a spacing block, and new shocks) has not met our needs. It looks like the Kelderman air-ride kit used on the Earthroamers may now be available. It was my first choice in 2009, but was not available then. I may also look into new rear springs (from Deaver Springs) and supplemental air bags. As soon as I finish unpacking I'll add a more detailed post.
Bob, a few questions if i may
1. what is the wear like on the conti's.
2. Also do you have detailed pics of the trimming required at the front in order to get the tires to fit.
3. What is the backspace or offset of the wheels, and what model of the ricksons are they?
4. Finally do you have a link on the front flares? And any idea if there is a gen 3 dodge version?
Thanks in advance!
Love the rig, it's been my inspiration for my build
Hi Bob.
How many miles o you think you will you get out of the conti's?
What's a good source for them tires?
Also how the wheels balance out?
Any issues with vibrations?
Thanks again!!
1. The MPTs are wearing evenly. I'll rotate them before our next big trip. They won't last as long as the OEM tires, but are much better suited to our application.
2. We used the front fender flares from Earthroamer as no others were available. We were in a rush to get on the road when they came in, so I didn't take detailed measurements and pics of the process.
3. The custom 20" Rickson wheels were designed so that they are reversible to allow me to carry a single spare. The front and rear track are now 79.5". With a 13.2" wide tire this puts the outside edge of the tires at 92.7". I would need to go back and check the drawings to determine the offset numbers. It will vary by truck and model year. Contact Rickson if you need help figuring it out for a specific truck.
4. Flares were from Earthroamer. They will build on a Dodge platform, though I'm not sure if anyone has ever ordered one. You may want to contact Bushwacker. They carry a wide range of fender flares, just not one for my model.
