No-Slip Positraction System

Never get stuck again!

RodMiller

Powertrax No-Slip is the breakthrough technology that SUV, Pickup, Car Owners and serious Off-roaders have been waiting for. Over three years in developoment and testing Powertrax now brings precise synchronization to extreme traction output. You can feel the difference as soon as you hit the road -- and as soon as you leave it. Rod Miller

Powertrax performance positraction systems.

Expanded view of no-slip traction system.

Exploded View

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 Aerostar, Bronco, Excursion, Expedition, Explorer, F150, F250, F350 pickup trucks, Ranger and Vans.

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.

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 Powertrax® Traction No-slip systems are 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 Powertrax® Traction Systems are your answer.

The Powertrax® Traction No-slip systems 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 Powertrax® Traction No-slip systems will allow for full wheel differentiation to prevent additional tire wear. Operation is smooth, quiet and dependable.

The Powertrax® No-slip performs under a variety of rugged conditions. Whether it’s snow, ice, mud, sand, gravel, or the street, the POWERTRAX® Traction System will help get you to your destination. Its extremely rugged for towing your boat, RV, or trailer is no problem with the No-slip system installed. Never get stuck on the boat ramp again. It's also ideal for vehicles with plows or that operate in construction areas.

  • 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 contol 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

Identifying Vehicles Equipped with OE Traction Adding Differentials

Ford cars and trucks from 1968 on have an axle code on the Certification Plate that can be used to determine if the vehicle is factory equipped with a limited slip differential. The Certification Plate can be located on the lock face of the left door edge. The plate layouts vary depending on the year, but in every case the axle code section is clearly marked as either "axle" or "ax". Ford axles codes contain one or two character. Any code beginning with a letter (an alpha code) indicates the vehicle is equipped with a limited slip differential EXCEPT as shown below. Some trucks with axle codes that are numbers only (numeric codes) are equipped with limited slip differentials. Please refer to the information below:

Cars, all alpha codes are limited slip except:

1968, all except L 1975-76, all except E, G 1982, all except B, F, Y
1969, all except B, C, D, E, F 1977, all except B 1983, all except A, B, F, J, Y
1970, all except B, C 1978, all except B, Y 1984-1990 all except F, Y
1971-72, all except B, G, H 1979-80- except B, F, G 1991-95 all except B, F, Y
1973-74, all except A, G 1981, all except A, B, F, G, Y  

Trucks, all as shown below are limited slip equipped:

1970-82, Rear, all alpha codes, no exceptions
1980-95, Front, all code 2
1983-85 Rear, all alpha except F9, G2, G3. Codes 22 &24 are also limited slip
1986 all alpha codes
1987-92, all alpha codes except R5, R6
1993 all alpha codes. Codes 18 & 19 are also limited slip equipped
1994 all alpha codes. Codes 17, 18, 24, 52, are also limited slip equipped
1995-96 all alpha codes. Codes 16, 17, 18, 24, 25 are also limited slip
1997 all alpha codes. Codes 17, 18, 24, 52 are also limited slip equipped

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.

* UPS Ground Freight charges will be added.
