Subaru R180 Rear Differential Block Disc Set – 100% Lock for Drifting & Drag Racing

For Subaru WRX STI drivers looking to eliminate slip and maximize traction, the R180 rear differential Block Disc Set is the perfect solution. The OEM clutch-type LSD allows some slip, but for hardcore drifting and drag racing, you need a permanently locked differential. This Block Disc Set replaces the clutch plates, forcing full power transfer to both rear wheels at all times, just like a welded diff—but without the risk of failure.

If you still want LSD functionality with improved grip, check out our Subaru WRX STI R180 LSD Clutch Plate Upgrade Kit. However, if you’re all about 100% lock for drifting & drag racing, this Block Disc Kit is the way to go.

Why Choose the Block Disc Set for Your Subaru R180 Differential?

• 100% Lock – No Slip, No Delay – Keeps both rear wheels spinning together at all times for full traction
• Ideal for Drifting & Drag Racing – Ensures instant power transfer for hard launches & controlled slides
• Stronger & More Reliable than Welding – Won’t crack or break like a welded diff, offering lifetime durability
• Reversible Installation – Easily removable if you want to restore LSD operation

This ensures a simple installation process with everything needed to lock your Subaru R180 LSD permanently for maximum performance on the track or strip.
