After some long threads and lots of measuring I got hold of some shocks for the rear of my tracker
I have given my self 5  inches and a bit more drop around 13 and abit total travel in all.
I had to slightly adjust the brake line and the A arm to get a better angle on the prop.
Also cut to slots in the bottom spring base to allow me to clamp the spring. I may add some cones as the spring drops out the top by 3 inches just on the stock bump stop.
Here are a couple of pics on the HI LIFT I will take some out on the trail this weekend,
You can also see my rear winch that was added a few weeks ago.
This picture has the new shock on the right and the old one on the left



Will do the strut mount flip at the weekend and maybe look at what i can do to gani a little more on the front
