Brabus Monobock II Wheels for Mercedes-Benz

Brabus Monoblock II (often nicknamed “The Blade” or “Tri-Spoke”) is the definitive 1990s statement piece for Mercedes-Benz tuning. While modern Brabus wheels favor multi-spoke “Platinum Edition” designs, the Monoblock II remains a high-value collector’s item for those building period-correct “Pre-Merger” style W124, W126, or R129 cars.

1. Technical Specifications

The Monoblock II is famous for its massive, flat tri-spoke face that mimics the three-pointed star of Mercedes-Benz. It was produced in both single-piece (Monoblock) and ultra-rare 3-piece versions.

• Common Diameters: $17″$, $18″$, and $19″$.

• Common Widths: $8″$, $8.5″$, and $9.5″$.

• Bolt Pattern: $5\times112$ mm.

• Center Bore: $66.6$ mm (Standard Mercedes).

• Manufacturing: Produced for Brabus by Ronal in Germany.

• Key Offsets (ET):

  • $17\times8″$ ET30: The standard fitment for W124 (E-Class) and W201 (190E).

  • $18\times9.5″$ ET26: The aggressive “deep-dish” fitment designed for the R129 SL and W140 S-Class.

2. The 3-Piece Variant (The Holy Grail)

While the one-piece Monoblock II is iconic, Brabus also commissioned a 3-piece version with visible perimeter bolts. These are exceptionally rare in 2026.

• Construction: Forged centers with spun aluminum lips and barrels.

• Repairability: Unlike the one-piece version, you can replace or upsize the lips on 3-piece units to create custom offsets.

• Value: A set of 3-piece Monoblock IIs in good condition can fetch double the price of the standard one-piece versions.

3. Verification & Authenticity

Because of their simplicity, “reps” (replicas) were common in the late 90s. Genuine Brabus Monoblock IIs will feature:

1. Face Engraving: The “BRABUS” logo is deeply engraved into the face of one of the spokes (usually near the center).

2. Rear Casting: Flip the wheel over; you should see “Made in Germany” and the Ronal logo cast into the back of the spokes.

3. Part Numbers: Authentic part numbers typically follow a format like 9518-32 (for a $9.5\times18$ wheel).

4. Center Caps: Genuine caps are metal and often use a specialized security bolt to prevent theft.
