I reused the stock push rods on my slim since I was replacing the rocker covers with black ones...I went ahead an installed rock outs while I had it apart....I'm going to change my cams in my street glide an I ordered HD adjustables for this time. I used adjustables on my evo fatboy an that went well...a little awkward at first getting 2 or 3 wrenches in there to adjust them an lock them down but those were V thunder push rods, not sure how they compare to other brands.

 

I've always used 3 wrenches with my S&S.. Insures proper lock down without changing the adjustment...

 

You sure it wasnt because they now have hydraulic lifters instead of solid ones and now theres no adjustment necessary?

 

They quit using solid lifters in the panhead days so yeah I'm sure. Time & money savings with fixed length pushrods, you just drop the correct color coded one in the correct hole and button it up verses having to spend a good amount of time adjusting each pushrod to correct length. Big savings on a mass production assembly line.

Most big changes the moco makes is about cost streamlining not a better part or making a better product.
