PRODUCT DESCRIPTION
Spacer for BMW LSD carrier conversion for high gear ratios
Unlock the full potential of your BMW's differential with the RacingDiffs LSD carrier conversion spacer. Designed specifically to facilitate a seamless transition from low to high gear ratios (from 3.15 to 4.45) when installing a high-ratio LSD carrier, common in BMW E30, E36, and E34 tds models.
This indispensable spacer solves the problem inherent in the difference in crown wheel position between low-ratio (2.64 to 3.07) and high-ratio carriers. It allows enthusiasts to easily use LSD carriers from TDS models, overcoming the limitations of low gear ratios such as 2.64, 2.93, and 3.07, without the need for machining.
Main features:
Precision engineering: CNC machined from high-quality tool steel, ensuring exceptional durability and hardness, a precise fit, and long-lasting performance.
Complete kit: The package includes a meticulously crafted spacer along with 10 high-quality crown wheel bolts for a complete and hassle-free installation.
Simplified customization: The spacer eliminates the need for machining, simplifying the process of transitioning between different gear ratios, making it the ideal solution for customizing your gear ratio.
Included in the package:
1 x Precision spacer
10 x High-quality crown wheel bolts
Experience effortless gear ratio transitions and optimize your BMW's differential performance with the meticulously designed RacingDiffs LSD carrier swap spacer, a must-have for any differential customization project.
