Am in the middle of DIY'g a set of front-and-back SUMO Springs which I purchased l March of this year. Before starting the process I called the
manufacturer in California about a tech question and explained to the very
nice lady there that I was just getting around to it in my driveway now because
of a short shot of wonderful weather. They are going on an '11 Solera 24S. We double
checked the numbers on each set of springs just to make sure I had the
right ones, which I did...however...she offered a new free, updated set for the rear's
as evidently after three yrs. or so some owners have been getting distortion
and mis-shaping of the rubber blocks(less efficiency). She said that as of a
few months ago they changed the design slightly(more "ribs" now...) to remedy this problem. Since I had not put them on yet she politely told me to send her
a pic of the shipping box and a copy of the bill of sale. I offered to return them
but she said that is all her boss needs...keep them. The updated free set is
on the way as I type and am looking foward to getting them on too. Not bad and a little bit of luck, eh?
My point it this tho
...make sure you REGISTER the springs...so that they can
contact you in case something like this crops up. Super company and super
PS: Just hope the old rear Sumo's pop out and the new one's go in as easy as described. In contrast the front's are held in with a nut\screw combo at the jounce locations and was rather tedious because of the prone position I was
in and then having to reach up to find the nut with the socket...this is hidden
from direct view and inside the axle a bit. When I hit the other side I smartened up and reached in over the hanging tire from the outside and
using the braille method found the nut a little easier. Nonetheless, am stiff and sore today!
...the instructions call for a 10mm socket for the nut but I think a plain ol'
1/2 deep socket worked fine for me and was a snug fit(no rounding of corners...). Otherwise you will be using around a 12mm metric, or so, but
not a 10mm! Now...where did I put my registration papers??
