I agree with sorenson1610..search the topic as there are litteraly dozens of threads on this topic. I don't think you can go wrong with anyones kit, however some give better customer service than others...Ulmers would be at the top of the list in that case. The Super Torquers stuff is very popular ( Drag n Flys ) I use them with Turks black spring setup and I really like how it performs, perfect for 1000' drag racing and trail riding.
