I am getting ready to install some s&s 583 cams in my 07 ultra with about 25000 miles with only stage 1 work has been done before. After doing all the research and not finding what I am looking for I decided to ask those who have done it. Do the lifters need replaced or will the stockers be OK? Thanks in advance.

 

Lifters and pushrods

Replace them .... Gaterman , S&S , Feuling, Woods .... Anything but stock C lifters. Don't forget new tensioner shoes.

 

If you really want to do it right, go with a Fueling cam plate and oil pump, S&S gear drive cams, lifters and S&S adjustable push rods

it isn't going to be cheap, but it will resolve any oiling system concerns, gets rid of the tensioners, you won't have to pull the rocker boxes, and you will be able to set the valve lash to spec.

the sound of gear drives is like music to me....

 

Comp Cams 870-1 lifters......working for me.

 

IMHO It would be best to replace lifters and push rods. I just completed a Stage II at 24K and didn't consider for a second reusing original lifters on new cams. I was taught long ago to never reuse lifters with existing wear patterns on new camshafts. Even though this is not a racing engine application it should be a consideration or question as to the quality of the OEM parts.

 

Thanks for the info. That's what I thought. The comp lifters are good for me then.

 

Pretty sure an 07 didn't have C lifters since my 2010 had B lifters? C lifters are made in Mexico and a few issues, A & B lifters were made in the US and had little to no issues. Rule of thumb is if your going to be in there anyways might as well just change them at the same time as insurance. Went though this back when I was putting my TW-555 cams in my 96". At the time the same threads were split between those that said you should and those that didn't. Never saw anyone post that they didn't and all hell broke loose, just you should and that I didn't with no issues. That was back during the Harley A&B lifters, after the C's came out even the stock ones had issues with no upgraded cams. I had the money at the time and went with Woods lifters, not sure if I really needed them or not but for my first cam install I wanted it done right and didn't want to cut corners if I didn't need to.
Pretty sure all your going to hear is what folks decided to do not because they had issues from staying with there stock lifters. Up to you if you can afford new ones or not.

 

Along the same lines, Crane Cams 10530 lifters work great as well. Been running them in my Sporty for quite some time (same lifters the Twinkie takes) with no issues at all.

They are basically identical to the "A" lifters. You can see some pics and detail HERE

The only real reason you should need new lifters is if you have a failing one, want to run solid/semi-solids, or are expecting clearance issues with the anti-rotation flats due to high lift cams.

 

The old " dont reuse the lifters" was for non roller cams, when the lifters and cam did wear in together.

I would not have an issue reusing roller lifters, I actually did when I installed the TW222's in my bike.
