Some say they are shocked I didn’t have one by now, let’s just say i needed to ensure the route I wanted to go is all!

There was no way I wasn’t going to get one, it will be one of the best modifications for me in the traction category. I shouldn’t get stuck as much with an LSD providing me significantly more traction than not having one!

The Limited Slip Conversion Kit installs into your non-LSD open differential, converting it into a proven and competitive limited slip differential that enhances your traction needs. The Limited Slip 1.5 way LSD will considerably improve handling in daily driven, street/strip warriors, or a full race vehicle. All products are constructed of only the highest-quality hand-selected materials. With over 500,000 miles of vigorous professional performance testing (SCCA, drag, rally, hill climb, ice, rain, etc.), they have been able to fine-tune each application through specific heat treating and Rockwell testing to achieve maximum performance and reliability. Each LSD Kit is assembled with pressure-tested 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 are confident that when you choose the Limited Slip Conversion Kit, you are choosing, by far, the best-limited slip conversion kit on the market.
