Precision Shim Pack for BMW Type 215 Final Drive – MF-TRS-SKE92

Build your drivetrain the right way. This dedicated MFactory shim pack is the essential setup kit for correctly dialling in ring and pinion lash on BMW Type 215 final drives when fitting an MFactory helical centre. Expect quieter gear mesh, consistent side bearing preload and long-term reliability. Custom engineered to cut installation time by around 50 percent and not supplied by the dealer, this is the right tool for a proper limited slip conversion.

Perfect for fast-road, track-day and daily-driven builds on popular 1 Series, 3 Series, 4 Series and Z4 applications that run the 215 carrier, this 4-piece pack delivers repeatable results and a clean, noise-free mesh when setting backlash on your torque-biasing unit.

Why this shim pack

• Essential for accurate backlash adjustment and side bearing preload during an LSD conversion
• Purpose-designed by MFactory to speed up installation and ensure a precise, repeatable setup
• Tight tolerances for smooth gear engagement and reduced gear whine
• 4-piece assortment for straightforward carrier alignment and ring gear positioning
• Genuine MFactory quality with limited lifetime warranty
• Not available from BMW – the correct solution for performance builds and helical upgrades
