Performance (continued)

As shown on the previous page, when a wheel loses traction, an “open” differential di-

rects all engine power to the slipping wheel, and virtually no power is applied to the non-

slipping wheel. The “limited-slip” differential also directs most of the engine power to the

slipping wheel, but does apply a minimal amount of power to the non-slipping wheel. The

amount of torque transferred decays as the friction clutches inside the “limited-slip” dif-

ferential burn up or wear out. Both the “open” and “limited-slip” differentials can cause

the slipping wheel to spin up wildly, worsening the vehicle’s condition and making it more

difficult to gain traction. The Powertrax No-Slip Traction System directs engine power

to the non-slipping wheel to provide the vehicle with the traction required. It transfers

minimal power to the slipping wheel and eliminates unwanted wheel spin-up. Traction

output is optimized.

Wheel spin-up and abrupt stoppage can cause severe driveline trauma. This occurs easily

with “open” and “limited-slip” differentials that rush power to a wheel that is slipping or

becomes suspended in mid air, even momentarily. When abruptly stopped by the wheel

re-connecting with a high traction surface, the driveline attempts to absorb the extreme

shock. Damage to driveline components can occur. Axle shafts may flex, bend or break.

It is not uncommon for vehicles with bent axles or damaged gears to continue to be op-

erated by unknowing drivers. Breakage of axles, gears or other driveline components is

extremely dangerous, and the vehicle should not be driven. The Powertrax No-Slip Trac-

tion System gets rid of troublesome wheel spin-up and improves driveline durability and

reliability.

Be aware that excessive power can break any driveline component. Vehicle owners that

choose to increase engine horsepower, install larger diameter tires or make other vehicle

modifications without increasing driveline capability are especially subject to driveline

failure. The Powertrax No-Slip Traction System is designed for reliable and durable use

within the specifications intended for the specific size and make of the vehicle’s original
