Source Engineering Arms and REK gets my vote.

[jpsageusa]

Last summer I took the plunge to install the Source Engineering trailing arms and REK. We finally got out on the road. It was worth the money! The drive from Whidbey Island, WA to Portland, OR was much improved. I5 through Seattle is no picnic and I the porpoising was all but eliminated. I would hit a rough spot and it was less severe than in my Ford based Class C.

Now would I pay someone else to do the work? Yes if the price was right. It is not a difficult job but it is hard work. And you have to have large tools. You have to have 33mm, 34mm and 1 1/8" sockets. I spent a good amount of money on tools. I bought a torque multiplier that worked good for the lug nuts but unless you can get the coach high enough it is too long to use on the vertical bolts. I ended up building a torque wrench extension that allowed me to apply the 450 ft lbs needed for tires and suspension nuts.

The REK is easier to install but you have to be aware of what air lines do what. My installation got complicated because my air compressor governor failed at the during the installation.

Finally, since I am driving by Source Engineering tomorrow I am going to stop by and have them do a safety inspection of my install.

Bottom line is that the coach is now feels much safer. It is still a full time job to drive since it does like to wander but it feels safe to drive. I plan on getting it aligned just because it shouldn't hurt.

Yes the REK makes a huge difference. I think if you changed to the TRW steering gear you'd notice a big difference. I've done "everything" to mine and still have slight wander when pulling toad on really windy days. You can do a search for "rr4r chassis upgrades" and read a thread I started about our 4 bag chassis. Feel free to contact me if you have questions.
