The Shocks of Champions!
All PEP shocks come with detailed explanation sheets allowing you to dial in your shocks for different terrain or racetracks. All of the PEP front shocks come with easy spring tuning triple rate springs and crossovers. The short spring on the top of the shock works about 10% of the wheel's travel and soaks up small bumps plus the acceleration of the quad. The medium sized spring in the middle of the shock works about 20-30% of the wheel's travel and acts in mid size bumps, braking bumps, and whoops. The remaining percentage of the wheel's travel is absorbed by the large spring located on the bottom of the shock soaking up landings from big jumps.

The most rugged ATV shock you will ever see! Notice the triple rate springs. Different size bumps, or "hits" are soaked up by three different size springs.
PEP "ZPS" Front and Rear Shocks:
Now into their fifth year of existence, ZPS (Zero Preload System) shocks are PEP's latest creation. Recommended for Pro and "A" level racing. Most recently the ZPS shocks were used to capture the first four places at the prestigious12 hours of Pont De Vaux annual ATV race. These are the shocks that have bogged down all of the PEP distributors. They simply can't make them fast enough. Currently making up 70% of all sales,(and growing daily) these shocks are the best thing to enter the sport of ATV Racing since the fourth wheel. To take full advantage of this superior shock system, PEP recommends that ZPS shocks be used in conjunction with one another. The reason for all the fuss, is that these shocks allow the rider to adjust his ride height without sacrificing any wheel travel. For example an ATV with 12" of wheel travel could be set to sit at a ride height of an ATV with only 8" of wheel travel. What does this mean? With the variable centre of gravity, cornering speeds can increase greatly. Another added bonus with a variable centre of gravity is the ability to obtain more traction than a higher conventional sitting quad. Another way to explain this is that the chassis "floats" on the suspension, allowing for maximum weight transfer. Since the wheel travel remains the same, the shocks provide the same terrain gobbling smoothness, and big hit absorption as the LTD Mass Shocks. There are plenty of technical things that happen to allow for these extraordinary shocks to work the way they do, but we figured we could spare you all the complexities and let British Champion Paul Winrow, say what he thinks of the ZPS shocks:
This is the ATV World Laeger Banshee piloted by Paul Winrow current British Quad Champion and 3 times winner of the 12 Hours of Pont de Vaux World Championship, Paul’s choice of shocks are PEP ZPS.
"It's like riding my Supermoto bike and my Motocrosser at the same time! I can go into a turn fast and hard without worrying about high siding. It's amazing that I can do this, without compromising the quality of the shock's ability to soak up hard landings. With this combination I feel more in control with less fatigue, that results in going faster and winning." –Paul Winrow
Front: Rear:
The ZPS fronts come with the adjustable triple rate springs and crossovers, a unique multi sensing damping, the one-of-a-kind ride height adjustment, and adjustable remote gas reservoirs. All rear ZPS shocks come with unique multi sensing damping and spring characteristics allowing a firm to soft spring rate. The one-of-a-kind ride height adjustment, adjustable remote gas reservoir, and external compression and rebound adjustment all add up to the premier shock for ATV racing. This shock is available for all link and no-link applications.
   
PEP "Limited Mass" Front and Rear Shocks:
The Limited Mass shocks, short for "Limited Mechanical Active Suspension System" account for about 30% of PEP shock sales and are designed for Pro and "A" level riders that demand the most from their suspension. This type of PEP shock has provided pro ATV racers with a championship winning suspension. To be more precise 3 SCORE ATV Championships, 3 Mickey Thompson Entertainment Group Championships, Over 30 Pro and A level AMA Grand National Championships, and countless local and regional championships throughout the world.
Fronts: Rear:
Adjustable triple rate springs and crossovers are used. The mechanical active damping with external damping adjustment increases the ability to turn faster by allowing less "chassis roll". It also allows more of a "lift" for jumps and an anti-bottoming control when landing. This rear shock is available for no-link applications, such as the ones found on Laeger and Lone Star frames. Offering the same qualities of the front LTD Mass shocks, they should be used with LTD Mass front shocks only. It features a dual spring with tuneable crossovers allowing a firm to soft spring rate. Adjustable preload, compression and rebound damping are also found on this popular race shock.
PEP "Standard Race" Front and Rear Shocks:
These are PEP's entry-level performance shocks. They are designed for recreational riders, dune riders, and "B" and "C" class racers. Making up about 10% of PEP's overall sales, don't confuse the name "Standard" as being equal to your stock shocks. These are PEP's lowest price shocks, but are far superior to stock shocks.
Fronts:
All Standard Race front shocks come with PEP's easy spring tuning triple rate springs and crossovers. The shocks offer low maintenance and non-adjustable external damping. Internally they have competition proven bump sensitive damping that is tuned to work with the triple rate springs and crossovers for superior response to small, medium and large bumps. The top two springs have adjustable crossover rings for fine-tuning. Gas remote reservoirs are found for consistent damping and control. Preload is adjustable. They come preset and generally will not need to be adjusted. However they can be if so desired.
Rear:
This shock can be applied to all link and no-link applications. It comes with a single adjustable spring, remote gas reservoir, adjustable multi-stage damping, adjustable preload, adjustable compression and rebound damping.
