Hard steel is what it is. The stock clutch bell on my Trooper Nitro started to show some wear as I replaced the stock spur gear from plastic to hardened steel. Easily to replace and the price is very affordable. Think about getting this as spare if you are planning on buying the 1/10 scale Turnigy Trooper Nitro SCT.

It does fit the engine, but doesn't align properly with spur gear. Proper installation is possible, but slight modifications are needed. Illustrated on tummi . pl / trooper
