i believe my rear springs are getting weak,my sled has a bad case of the droopes.was wondering if anyone had the part # for the heavy duty springs.

I have the same issue with the 02' ZL800.....also looking for part # and good online supply source...

Need more information so as to suggest a particular spring..........how much do ya weigh / how do ya ride / have you had your shocks serviced yet?

I'm in the 225-230 range (too much good food as of late) and have this year gone to the 1604-050 / 051 rear springs combined with stock shock valving but medium wt instead of light oil in all my shocks. During my 100 or so mile ride yesterday the sled rides like a Caddy but handles like a Ferrari with no bottoming while set on the lightest sping setting and my rear clicker on #3. Sled is an 02 ZR 800 cce.
The spring specs are
.437 wire
83 degree
These are the stock springs used in the 98 / 99 / 00 standard ZR's. While they are a smaller wire than the stockers (.452) then have a fair bit more preload due to the 83 deg instead of the factory 90 deg angle leg.
Last year I ran stock valving / stock light shock oil and a set of 1604-194 / 195 (.460 wire at 90 deg) which are a stock Sno Pro spring. I found the sled was far too stiff for general riding and nothing short of brutal in the rough stuff.

IMHO the biggest issue is with preload not wire size of course when combined with a quality shock overhaul.

Rick,

Thanks for the reply. I'm at 185 lbs and the sled only has 2100 miles on original shocks. No rebuild to date. Being new to this, how often should the shocks be rebuilt/replaced and approx how much should this run $$$?

The shocks should be done first at about 500 miles (so the manual says but I usually dont' do em until the start of the second season unless I've had an issue) and at the start of every season after for peak performance. If you ride easy and or don't ride very many miles, every second season would be lots.
I made a mistake in my post as I'm running the springs in the medium position which makes me confident they would work 100% for you using the softer setting. When having the shocks done I would go with medium wt oil in all 4. The extra bit of dampening it adds seems to really suit the sled while maintaing a very plush but totally controlled ride.
Shock rebuilt / servicing prices vary depending on where you go, I would seek out a local "shock guy" and stay away from dealers.
Where abouts are you located and are you capable of taking them out yourself? If so I've got a buddy in Lewiston NY that does quality shock work, his prices are fair and he only uses top quality oil and seals.
The reason so many are not aware that their shocks are not performing up to snuff lies in the fact that the real good feel fades away so slowly that they don't notice until the shock totally fails leaving the sled riding like a buckboard.
