AST Zip, ARC, MINI ARC & Rider Cams

The Twin Cam system is engineered to allow both top and bottom cams to act as one without independent movement. 

With both cams acting as a single unit, our engineers were able to focus on specific characteristics on each of our cams in order to provide a well-balanced platform.

AST Zip Cam

The AST Zip (Accu Speed Technology) cam is the driving force behind our pro-shop series bows.   Exceptional arrow speed while maintaining a smooth draw cycle is paramount to any serious archer, the AST Zip cam delivers flawlessly.

Draw length-specific modules in one-half inch increments allow adjustability to accommodate different statures.  Adjustable let-off offers increases fine tuning for preference.

ARC / Mini ARC Cam

Sharing the great qualities of the AST Zip cam, the ARC & Mini ARC (Advanced Rotating Cam) system allows for a convenient draw length adjustment using a rotating module.  The Mini Arc cam accommodates shorter draw lengths from 24” to 26.5”, while the ARC cam accommodates longer drawn lengths, while maintaining exceptional performance and an unmatched draw cycle.  Although the ARC & Mini ARC cams need to be pressed for draw length adjustment, the simplicity of the rotating module is a favorable option.

Rider Cam

Incredible adjustability while maintaining performance is what makes the Rider cam a great compliment to our entry-level bows.   As the draw length is increased through its 13” of adjustment using a rotating module, the draw weight range increases to match the growing archer.  The Rider cam provides reliable performance in at all settings with speeds up to 315 fps.  All aircraft T-6 aluminum construction on the Rider cam and its module provide unsurpassed adjustability and reliability on our entry-level bows.

Additional Technology

Directional Venting

The beautifully machined lightening holes, or vents, in the risers of every Winchester Archery bow are not only good looking but serve a very important function. They are specifically designed to direct vibration towards the stainless steel stabilizer bushing so that your stabilizer can be most effective. This important feature allows you to use a smaller stabilizer and get better results.

Optional Grips

Standard on Quicksilver bows and as an option on other models, three different grips allow you to customize your bow and find a grip shape that meets your needs. Whether you prefer a narrow 2-piece style target grip in rubber or wood, or a solid insulating 1 piece grip, both are available for all Winchester Archery adult bows.

Stainless Steel Hardware

The use of stainless steel hardware on all Winchester Archery bows and Crossbows demonstrates our commitment to quality. Normal steel components rust…period. Stainless steel gives you the confidence to hunt in less than ideal conditions without concern for rusting screws ruining your bow. Why settle for anything less on a high quality hunting tool?


These simple but effective accessories are found on all Winchester Archery bows and crossbows. Speedsters help increase bow speed by increasing string momentum during the shot. In turn, the soft material acts as a silencer for the string and helps reduce residual string vibration after the shot.

Ultra Glide Dual Roller Cable Guard

The dual rollers in the Ultra Glide cable guard are mounted on nearly frictionless stainless steel sealed bearings to provide the smoothest draw possible and to enhance arrow speed. Capturing the cables during and after the shot helps reduce noise and vibration in what is already an exceptionally quiet bow.

Stabil-Lock Limb Pockets

Locking the limbs in a vice-like grip is the first job of these beautifully engineered limb pockets. Creating a stable platform for those limbs while shaving as much weight as possible was the challenge and clearly the challenge was met successfully. Limb pockets that are solid, secure and lightweight enhance the performance of each bow.

“Sudden Stop” String Dampener

Lateral adjustment on the Sudden Stop allows the bowhunter to find the ideal “sweet spot” for the string to land on the noise killing control cushion dampener. True 3K Carbon Fiber Weave extension rods (not fiberglass like other string stops) contribute to the dampening characteristics of the Sudden Stop & allow Winchester Archery bows to be the quietest ever.

The Pro-Link Pocket System

Winchester Archery, a leader in advanced technology has developed a new pocket system and has integrated this advancement into many of our line up of Pro Shop Series models. The U.S. Patented Pro-Link Pocket System provides multiple benefits to the archer. First, the design eliminates threaded limb bolts that may strip, fatigue or break. Traditional limb bolts provide merely 10 lbs. of adjustment, while the new Pro-Link Pocket System offers more than 16 lbs. of adjustment in just 3 simple revolutions of the center barrel.  Aside from the ease of weight adjustment, the 7075 T-6 Aircraft Aluminum-grade pocket eliminates any limb vibration from making its way down to the riser and eventually to one’s hand, making every shot a “dead-in-your-hand” shot.
