#4 Flat Blades 4/32in 12 Pack

The #4 Flat Blades 4/32in 12 Pack from Allstar Performance is the professional-grade replacement blade set engineered for heated tire groovers used in drag racing, circle track, and serious street performance applications. When tire grip and heat management are non-negotiable, these flat blades maintain consistent groove depth across the entire contact patch, allowing drivers and teams to dial in traction characteristics and monitor tire wear patterns with precision. This 12-pack ensures you have plenty of replacement blades on hand for race weekends, testing sessions, or high-volume shop operations without downtime delays.

Each blade in this set features a flat profile geometry that cuts consistently at a 4/32-inch depth, the critical threshold where many racing tire compounds show optimal performance characteristics and thermal behavior during high-speed acceleration and cornering. Manufactured from hardened steel, these blades resist dulling during repetitive grooving cycles and deliver clean, precise cuts without chattering or inconsistent depth variation that would compromise tire performance. The flat blade design—as opposed to angled or specialty profiles—provides straightforward groove formation ideal for tires requiring standard racing grooves, making these blades compatible with most Allstar Performance heated tire groover systems and similar aftermarket equipment.

Competition mechanics, performance shops, and racing programs that run consistent tire programs benefit most from keeping a full inventory of these replacement blades. Whether you're prepping slicks for a weekend event, maintaining a fleet of test tires, or running a high-volume tire service operation, the 12-pack quantity minimizes reordering frequency and ensures blade availability during critical preparation windows. Blade replacement is straightforward on Allstar groovers; these #4 flats integrate directly into the standard groover chuck system without modification, keeping your tire prep workflow efficient and your groove depth specifications within tolerance.
