Hi all !!
I was just doing some work on my rear suspension and decided to go with the 0704-938 & 939 springs that were sugested in an earlier post. (I am 6' 1" and around 235) When I got the springs they seemed to be just like the ones in my sled (98 zrt 600) only the one leg was longer. Seemed to be the same diameter and number of coils and real close on the angle of the short leg ???? Any ideas ?

I also was wondering about where to mount the rear suspension arm. There are 5 holes in the rail to mount it. Is there one place it should go or what changes if you use the holes closer to the front or further to the back ???

Thanks !!

The stock rear arm sp's for a 1998 Zrt 600 are 1604-050-051 which has a wire dia. of .437". The 0704-938-939 sp's have a wire dia. of .452". So they are a heaver sp. The recommended heavy duty sp. for your sled is 1604-194-195 (R/B 1704-088-089) and that sp. has a wire dia of .460" All the other diemensions of the sp's are the same except for your longer arm. The stock rear arm to rail mounting position is the second hole back but in your case I would mount it the third hole back and leave the over center cross brace in the second hole.

The 194/195 are not worth a crap for riders over 180lbs in my opinion. A better HD spring is the 076/077 these are the listed HD spring for the 97 ZR 440...which incidentally comes stock with 194/195's. I was about 200lb when I got my 440 and the stock springs were not up to the job at all for a hard rider. The 076/077 were the best springs I ever ran and I'd still be running them if I could.

Ok, I found them (R/B 1704-074-075) but that sure is a strange sp. because of the 97* angle and nine coils insted of the 8.750 coils and the 90* angle?? You would think it would be weaker but it is listed as a H/Duty sp.

I have those springs ordered (1704-074/075). I'll be able to let you know how they feel in the garage :nosnow: after I pick them up and get them installed.

You'll be surprised. They are the freaking bomb if you are a hard charger. But they beg to be matched up with a 110-125lb straight rate spring on the ski shocks too. Balances out really well. More then likely require some valving changes in the shocks, but thats personal preference. So many people get this whole suspension tuning thing so backasswards it just perplexes me.
