  Phantom Grip - Limited Slip Differentials
Max Performance, Minimum Price
Our Limited Slip Differential will provide you with:
  1. Increased Towing Capacity
  2. Maximized Tire Wear
  3. Safer, Wet Weather Driving
  4. Fun To Drive in Conditions

The Phantom Grip LSD, otherwise knows as Limited Slip Differential, conversion kit, installs into your non-LSD Differential, converting it into a proven and competitive limited slip differential that enhances your traction needs.

Phantom Grips 2-way LSD will considerably improve handling in daily driven, street/strip warrior, or full race vehicle:

  • In cornering and braking, it functions as a disc-type limited slip.
  • In hard acceleration, the Phantom Grip works as a locker causing  both wheels to receive equal power instead of just one wheel spin.
Every Phantom Grip LSD is constructed of only the highest-quality aerospace alloys. With over 500,000 miles of vigorous performance testing (SCCA, drag, rally, hill climb, ice, rain, etc.), we have been able to fine tune each application through specific heat treating and rockwell testing to achieve maximum performance and reliability. Each Phantom Grip unit is assembled with blueprinted matched sets of progressive-rate springs to achieve equal load distribution to the disc plates, which dramatically enhances reliability and performance. With such a passion for perfection, we at Phantom Grip are confident that when you choose a Phantom Grip unit, you are choosing, by far, the best limited slip conversion kit on the market.
