Well we all here have been wondering what is the best replacement shock for tricks to do one our 660's to make them handle better.

1) dampers, i found that the stick style for yfz450's work great.

2)springs, i tried the high lifter ones and was not a big fan, them do stop the body roll, but the performance still sucks.

3) shocks yeah right who has $600 or more for a pair of shocks, hmm, well maybe you dont need to spend that. I am here to tell you that the stock yfz450 shocks work on a grizzly.

Igot a pair of 05 yfz450 shocks off his bike (he got fox evols) We want to try and see if they worked on my grizzly, with a little work you can get them in there. they are alomst an 1" taller, so take the spring rate down and take all compression and rebound out.

We got them in and rode for 60-80 miles today, and i had the ride height a little low, so i took the pre load up to 1 1/4" on the spring, and compression at 1 click, and 6 on the rebound for now.

These shocks do what the high lifter spings do with the body roll, but also add performance, and adjustablity. I was flying through the rough stuff today, and the fast you go the better the keep get, wish i would have tried sooner.

So for $150 -$250 you can pick up a set of front shocks and have a fully adjustable piggy back shock that works great, oh and they can be rebuilt, and revalved to any way you want them.

Sorry for the dirty bike, was riding all day. and my 686 can run down a piped, clutched, and pod modded grizzly 700, 2 of 3 hole shots wonand never lost in the drag. grizzly tech better mod the 700 more! LOL

By the tape I got 2" at the center of the bumper. I have dampner and rebound at 2 clicks off closed and the nuts compressing the springs at 1" off the top.

The ride quality is great. They worked great and gave me the added clearance I needed for the 29.5s. Everything was great up front, but I tore the rear end all to ****!!

Jasson, I just purchased a used set of raptor shocks, that look the same as what is on your unit there--I've read that the yfz ,banshee, and raptor use the same, or same dimensions. Do you know this to be true? I purchased these for only 100.00 for the pair, I guess even if they dont fit I could sell them for a small profit on ebay

I did this 3 1/2 years ago. Nothing new. They work good for A wile then start to get soft from the weight of the grizz(can be rebuilt though). I ran them with high lifter rear springs and it seamed to have good balance.
