1034 APPLICATION GUIDES RUBBER TRACK Selecting a stud length Woody’s® considers 1/4” to 3/8’’ penetration to be optimum. The penetration is measured from the tip of the stud to the top of the track lug. Review the Penetration Recommendation Cart to determine the appropriate stud length for the track that is installed on your snowmobile. Deviating from the recommended length may cause premature track wear, tunnel damage and /or loss control. Always consult your dealer and your owner’s manual when installing studs and remember to balance the turning carbide length to the number of studs installed in your track.

Deviation from this recommendation can result in premature track wear, tunnel damage and/or loss of control. TRAIL/TRACTION BALANCE RECOMMENDATION CHART Consult your snowmobile owners manual or contact the dealer to determine the snowmobile’s horsepower. It is essential that you have adequate tunnel protection.

Riding style and terrain must be considered. Track Belt Thickness Track Lug height Selecting stud design Woody’s® designs studs specifically for different riding terrain and levels of riding skill. To determine the type of stud to install, the snowmobile rider must evaluate not only the Woody’s® traction and control products available, but also determine personal riding style and the terrain to be traveled. Two categories of studs are available, the conical and directional. Each category has several designs within to accommodate different riding styles and terrain. The conical studs, such as the Gold Digger® Traction Master® and the ExcelTM, are designed to penetrate hard-packed snow and ice, The directional studs, like the Mega-Bite®, are designed to hold more area for traction on softer ice and terrain. Woody’s® studs are available with a 1/4’’, 7mm or 5/16’’ and 7mm are smaller in diameter at both the head and shank, therefore lighter. These studs require a 7mm support plate for a correct fit. Situations where these studs might be considered are racing (light weight) and where ultimate strength of a larger stud isn’t necessary. The 5/46’’ studs have a larger head and shank. These studs require 5/16’’ support plates. Sleds over 100 horsepower (600cc range) and aggressive riding are good benchmarks for a decision to use 5/16’’ studs. Support Plate Selection Consider Round, Square, Double Digger®, Steel or Aluminum when determining the best support plate: 1. Round: use with 7mm or 1/4’’ studs that are .875’’ or shorter in Length; light weight. Available in steel or aluminum. 2. Square Steel: economical and strongest support plate available; recommended for all-purpose trail riding. 3. Square Aluminum: durable and light weight for performance. 4. Double Digger®: added support for performance; available in aluminum only.
