I added viper shocks to my 2000 srx
you need longer transfer rods, otherwise they bottom out on the bushing and don't allow the full rebound. ( threrefore sled sets jsut as high as original)
I made simple steel bushings to effectively extend the rods on the transfer rods. ( same daimeter as the rod, with thru hole for the end bolts. simply makes the rods 10mm longer. I then made ( you can buy) different plastic bushings to get the gaps just right. sit on the sled and measure the gaps after installing the extensions. you ideally want the same gap top and bottom. you end up thinning up the bottom and adding some width to the top.
I weigh 190 without gear. I set the fra to the stiff setting and on the first ride it was tippy. ( thought what have i done !!

)
i set the fra to the softest setting, giving a little more setin, and a softer ride on the supposedly "stiff" viper shocks and it rides AWESOME. corners on rails again and much more travel.
I flipped the front shock mounts over and then left to right. did some shimming and grinding to clear the shock ends. this raises the front the appropriate 1"
you can buy shock extensions too or use viper front shocks with new mounts.
5 turns of the limit straps made a difference in ski pressure vs. lifting a little out of the corners, so play with stuff on the trail and you will be amazed at how adjustable things are
I left the original spring preloads when installing. maybe backed off the front skid shock preload a little.......
hope this helps
