Tillotson 196cc 68mm reinforced racing block designed for high-performance kart racing engines. Featuring a cast iron sleeve and strengthened casting, this block provides superior durability and reliability compared to standard clone or Predator crankcases. See full product details below.
The Tillotson 68mm racing block is engineered as a high-strength foundation for 196cc kart racing engines. Designed specifically for performance applications, this reinforced crankcase provides significantly improved durability over standard clone or Predator engine blocks, making it ideal for high-RPM racing environments.
This block features a 68mm bore with a cast iron cylinder sleeve and reinforced casting throughout high-stress areas. The additional material and structural support help prevent flex and cracking under extreme load, allowing builders to safely push engine performance to higher levels.
Designed with kart racers in mind, the Tillotson block includes mounting provisions for standard top plates and fuel tank setups, making it compatible with many existing GX200 and clone engine components while offering a stronger platform for performance builds.
This block is widely used in AKRA, NKA, and WKA racing classes and is considered one of the strongest crankcase options available for clone-style engines.
This block is designed to work with a wide range of GX200/clone-style components, allowing flexibility in engine builds:
