Titanium Pushrod ends are far lighter and yet stronger than Steel
With the Big Bird Kit You get 16 Titanium Pushrods ends with 4-40 threads and 2 Carbon Fiber Tubes that are 32" long.
The Pro Series Pushrod Ends from Abell RC are far superior to any others on the market today. Carbon Fiber tubes are very strong and light but they do have a weakness, They can easily split lengthwise with the grain when subjected to lateral forces. The Crashis Clay Pushrod ends completely eliminate this weakness because they fit over the ends of the tube rater than inside of it, this design also has another benefit, by design there is three times the surface area for the recommended JB Weld to bond to!
