The Powertrax® Traction No-slip systems are the latest design in traction adding differential technology. It combines the smooth operation of a limited-slip differential, with the traction performance of a locking differential for Astro Van, S10 Blazer, Blazer Jimmy, Silverado, Sonoma, 1/2, 3/4 and 1 ton pickup trucks.

The Powertrax No-Slip Traction System is the latest design in traction adding differential technology, The No-Slip Traction System will deliver engine power to both wheels when coming off the line. Don't let one wheel spin effortlessly anymore, never get stuck again! Our no-slip unit combines the smooth operation of a limited-slip differential, with the traction performance of a locking differential.

 

A precise synchronization mechanism eliminates the ratcheting sounds typical of other locking differentials. Special gear and spring design reduce the backlash and therefore driveline windup. Only ultra strength material is used which is 67% stronger than titanium. The No-Slip Traction System will significantly enhance the traction of your light truck, sport utility vehicle, or van by sending the engine power to the wheels that need it most. Yet on dry pavement, the No-Slip Traction System will allow for full wheel differentiation to prevent additional tire wear. Operation is smooth, quiet and dependable. owing your boat, RV, or trailer is no problem with the No-Slip Traction System installed. Never get stuck on the boat ramp again. It's also ideal for vehicles with plows or that operate in construction areas.

Installation is simple because no ring and pinion set-up is required. In addition, no special tools or oils are needed. Step by step model specific instructions are provided with every kit. The No-Slip Traction System is the ideal solution for just about any light truck, sport utility, and muscle car on the road today. Whether you need the safety of added traction for daily commuting, recreation, work, or just so your muscle car puts power to the pavement instead of burning one wheel up, the No-Slip Traction System is your answer.

  • Gives two-wheel drive vehicles the traction power of 4 x4's
  • Delivers ultimate traction to four-wheel drive vehicles
  • East to install -- do it yourself without any special tools
  • Smooth and quiet operation
  • Precision synchronization control makes friction clutches obsolete
 
  • Proven worldwide by serious off-road and performance enthusiasts
  • State-of-the-art engineering and design for maximum power transfer
  • Space-age Zytanium construction for highest strength and durability
  • Installs inside open, limited slip and locking differential cases

Front Axle Application Information:

 

The No-Slip works well on the front axle of 4-wheel drive vehicles provided a couple important guidelines are followed. The No-Slip should be used only on vehicles equipped with locking hubs on the front axle or with front axle disconnect. In addition, the vehicle must not be equipped with full time 4-wheel drive. Vehicles equipped with a No-Slip on the front axle should not be operated on the highway with the front hubs locked and 4-wheel drive engaged. Steering -- The affect on steering produced by a No-Slip may contributed to a degree of "under-steer" when turning under power. Sudden throttle changes during turns will accentuate "under-steer", especially on slippery or unstable surfaces. Following these guidelines will ensure very on-road derivability while still providing maximum off-road tractions. Be sure to maintain caution and drive carefully under control under all conditions.
