The pinnacle of 4wd/AWD front axle limited slip differential, now available through Loganbuilt! The wavetrac provides added traction by powering both front wheels of your 4x4 but allows for needed torque differentiating when one wheel begins to lose traction. When one wheel begins to spin, torque loss is detected and power is directed to the wheel with traction. This is the OPPOSITE of how traditional limmited slip differentials operate. Traditional LSD's transfer all the power to the already spinning wheel causing that tire to go up in smoke, forcing you to abort the run! The wavetrac LSD we have proven to perform flawlsely here at Loganbuilt with our 4x4 diesel,1.17 60' & 4.97 1/8 mile at over 142 MPH
