once in the car i dropped the outer bars. but when moving the spring around the garage, and decompressing it out of the car they are very helpful. but with the 1" all thread i didn't feel unsafe removing them to manhandle it into the car.

when decompressing it the plates of steel wanna spin, one is locked to the all thread with a castle nut and a grove that holds the nut. and the other plat is getting the impact of the compression nut rotating down the all thread. so having those plates stay aligned while decompression is helpful. i need to take better pictures. it works pretty darn well.

Also, the compression nut is welded to a 2ft section of pipe, and a bolt is welded to the other end of that. making it really easy to compress the spring with a huge wrench about 10 inches above everything in the engine compartment. and it slips through the hole and out the bottom of the car with the spring.
