after buying the coach last year, i added the 1.75" roadmaster sway bar to the rear to work with the stock one, and replaced the front sway bar with the roadmaster upgrade. in addition, i replaced the stock blisteins with Koni FSD's. These improvements made quite a difference over stock. the rear roadmaster bar is not cheap, but worth it, IMHO.
i have been reading about the sumo springs, and how great they are. i decided to try the jounce replacement version, for both the front and rear. they are a simple swap, no drill application (unlike the outboard, rear only full bracket version, which is also much more expensive). the front ones fill the space completely between the axle and the springs (where the current jounce stop is); the rear completely fills the space between the bottom of the frame and the axle, (also where the current jounce stop is). as soon as the coach tries to move, they begin to provide progressive resistance. i had them put on today, filled the water tank, hooked up the jeep, and took her for a test tow.
difference, IMHO, and well, well
worth the roughly $400 for them. if you want to put them on, you can save the labor; i just didn't have time to do it before our trip after easter down to charleston, SC for april school break. if anyone wants to improve their handling, i highly recommend them. you can really feel them working in the front, holding you steady, and they smoothen out the back quite nicely, too. i found the bigger difference in the front, at least initially. but you know there are there in the back, too....
the part #'s for the XL are:
also, for reference, the full outboard rear only kit is:
but it requires 8 holes to be drilled into the frame, 4 on each side. more money and much more labor; rear wheels need to come off in addition to the drilling. but they are supposed to be even better in the back, as they are outboard of the frame, over the spring, vs. under the frame and over the axle. and given how the back has really smoothened out with the jounce application, i may jump in all the way and put the outboard ones on, too. it's only money, after all
, and i love a smoother, more stable ride just as much as the next guy
will see after this trip where i go from here, but i am a very happy camper right now with them on.....
