Truck Block

Truck Block Overview

Scan-Pac Manufacturing is pleased to announce the addition of Gemini truck block sets to their product offerings. Our high quality truck blocks are designed to perform on over-the-road semi-trucks and buses. We are releasing two truck block materials, GEM200 and GEM301. GEM200 has been independently tested to FMVSS 121 and approved for semi-trucks up to 20,000 lb. axle weight. GEM301 has also been independently tested to FMVSS 121 and approved for 23,000 lb. axle weight. Both materials offer excellent fade and recovery in addition to low wear rates on the friction and mating surfaces.

These product offerings represents another addition to Scan-Pac Manufacturing’s family of Gemini friction products. Our blocks perform at a high level on truck braking systems, while maintaining the competitive prices offered by the Gemini family of products.

Scan-Pac is pleased to offer several of the most popular truck block sets on the market. All sets are available in both 20,000 and 23,000 lb. axle weight ratings. In addition, all of our block sets come carefully packed in individual boxes. Truck blocks usually ship within 1-2 days of the order date.
