Default Shock Suggestions?


I am interested in new Shocks for my 2001 Raptor, but am not quite sure what I want or need. Little about me and machine:

2001 Raptor (+3/+1 A-arms, Big Gun Exhaust)
70% Dunes, 30% Dirt ridding
225# rider (Beginner to Intermediate)

Been looking at a couple different setups PEP Limited Mass, Works tripple rate, and the Elka not sure which one (All of ebay).

Another note, any comments on the PEP Steering Stabalizer?

Any help would be greatly appreciated.

Don

Default Shock Suggestions?

I also mostly ride the dunes and have been running TCS for a while now. They work great!
Here's more info:
Deatiled Description:
<FONT face="Times New Roman, Times">So just what are Sag Control System shocks, and what makes them so good? This is a good question, and difficult to answer without getting too technical and confusing. Quad shocks are all “coil over” shocks, with springs on the outside, which push on the shock body at one end and on the shock shaft at the other end. At the end of the shock shaft inside the shock body is a piston. As the piston is moved up and down in the shock body oil moves through valves (holes) in the piston. These valves control how fast the oil can move through the piston, and this controls the dampening. SCS shocks are different from most shocks both in the way the springs work and in the way the valves work

Stock shocks have one spring. Most stock and aftermarket shocks have adjustable preload settings to change how much the spring is compressed, which allows you to set ride height and change the spring rate at the same time. Aftermarket shocks with multiple springs have collars, which slide on the shock body where the springs meet and allow the transfer of force from one spring to another while keeping the spring ends together. When one spring is compressed the next spring takes over. Usually most of the shock travel compresses one long spring, and when it’s fully compressed a second shorter and stiffer spring takes over. As this spring compresses, the collar slides up the shock body. On triple rate shocks a third spring takes over when the second spring is fully compressed. On SCS shocks, which come in both double and triple spring versions, the top spring is very soft and just serves to stretch the shock out when the wheels come off the ground. When the weight is on the quad this spring compresses. The sag of this spring is controlled by an aluminum spacer tube around the shock body which stops the sliding collar and transfers the load to the one or two main springs when the suspension is compressed to the selected ride height: Sag Control System. Changing the “preload” settings on an SCS shock will change the ride height but will not affect the spring rate.

The second way in which SCS shocks differ from most aftermarket shocks is in the valving. One time-honored way to control how fast the oil can move through the piston is to control the size of holes in the piston. Smaller holes produce greater dampening and larger holes produce less dampening. Compression dampening and rebound dampening can be controlled separately by putting one-way check valves on these holes, so one set of holes lets oil through the piston when the shock is being compressed, and another set of holes lets oil through when the shock is rebounding. Many high quality, premium shocks use this system. SCS shocks use another approach. Stacks of small metal shims are placed on both sides of the piston. When the compression or rebound force is light, these shims let oil through the piston for minimum dampening. However, when the compression or rebound force is hard, such as when landing a jump, the shims will bend and restrict the oil flow. The faster the oil tries to get through the shims the more the shims bend and restrict the oil flow. This makes the dampening proportional to the force on the shock. SCS front shocks provide additional adjustment by using reservoirs with compression dampening adjustment ***** similar to those found on rear shocks.</FONT>
