18404-08 Screamin' EagleŽ Premium Tapered Quick-Install Adjustable Pushrods
These premium pushrods are tapered for enhanced clearance at the cylinder head, allowing the use of higher lift cams. The one-piece chrome moly tube adds rigidity and durability, and the threaded adjustment feature provides easy cam installation without removing the cylinder heads or rocker boxes. To simplify adjustment, the tube features six flats, with one flat marked with a large dot for tracking the adjustment. The threaded rod features 4 flats to reduce wrench swing. Each pushrod features the Screamin' EagleŽ logo and is marked for "Intake" or "Exhaust". Kit includes 4 pushrods and required pushrod tubes.

I have a HD-Visa; I just exchanged 10,000 points ($1,000) for a Stage II 103ci Big Bore (27532-08). I am considering SE Pushrods. There are two listed; rather than asking which a better option is, I am just asking for some Pushrod insight? can anyone assist me?

TIA

 

Different views and opinions, but I will say that when I did my cam a few months back I choose option two. The reason being, I have seen only a few failures in the past couple of years with any SE adjustable and each time it was with the tapered ones. This made my decision for me, without this info I would have chosen the tapered ones because of what they describe, but I know what I have seen.

 

The -99A's can rub the tube tops and cause some noise. The nuts on the -08's have been suspect, but can be replaced with stronger which many do. If I had to do it over again and the -08's were available when I did my cams, I would have went with them. They are tapered so they don't rub and they are for higher lift cams.

 

Alas, depending on which cam you go with and who is doing the work, etc. you may not even need adjustable rods and can reuse stock or go with perfect fit rods.

 

the first ones u listed are the tapered one. I out those in my engine build. the only problem is the locking nuts are extremely brittle and break. after one split in half and one cracked while locking them down. i got 3/8-24 industrial nuts. which are long too. i ground the corners off for more clearance.

 

I like the tapered rods because they're easier to adjust for me.

 

Go with the Premium tapered pushrods. Most techs I believe will tell you the same thing. I have heard stories of the others collapsing.

 

Just checking, the 08's seem to be the consensus, do I need shorter tubes of can I use the same ones?

Pretty sure they come with new tubes.

 

They do come with new tubes, shorter ones.
