just for the record, i tried foam shocks way back when and was less than impressed. the adjustable units might be better, i have not tried them.
the shocks that i do recommend are the adj Rancho RS9000. i have installed dozens of these over the years and they do the job extremely well. what i have found is that you adj them once but the idea that you can fine tune the ride and handling is well worth the extra $$$. AND they take forever to start rusting.
think of it this way:
2 things i don't screw with (read cut corners), steering and brakes.
the way your suspension handles affects the steering AND braking. if you have too much body roll then you loose the control (or at least some of it) on corners, over wash boards and stopping. if you have to panic stop and the vehicle wabells around then you can not stop as fast or as safe as a vehicle that stays firm. too firm and the ride is uncomfortable.
with adj shocks you can dial in for YOUR driving style and ride want.
i don't know if anyone remembers the Black Diamond lift kit from 20 some years back. we could only get them in Canada for a very short time. the kit was complete and very nice, ride was great, cost was up there but what made me REALLY like the kit was the shocks were plated. they never did rust. they went on all shinny and purdy and 3 years later they still looked like new.
the shocks that come with most kits have a "Powder coated" white coating that rusts almost immediately after coming out of the box. s***ty fawking job and even though the kits are complete and nice the shocks look like crap after a year. even stock factory shocks look nice for years before rusting.
if i could make a recommendation, if you are designing a high end kit (and i feel Dob is one of these) then supply shocks that match the market you are targeting.
