The factory limited slip differential in the 92-2006 Vipers should be replaced with the torsion biased Quiafe
for ultimate strength, power distribution, and safe power delivery. We have tested these units in extreme drag
and street conditions with out failure over the years and feel this is the best unit on the market.

Remind us to do our differential cover support bracing also if you are planning on doing hard launches with slicks.
This is a nice upgrade to keep from shattering the support arms under hard launches with big power.
