    Hey guys, 
    Anyone used these adj PRs with the stock oem pushrod tubes? 

    I read about the adj PRs being fatter and rubbing on the stock PR cover tubes? 

    Is there any way of getting around this problem other than chucking them on a lathe and boring out the tops of the tubes? I don't have access to a lathe. 

    Bike is '02 softail
    Cheers

    Sorry, 

    Std adjustables (not the EZ install or quickies). 
    2002 TC 88 Softail with 96" later model heads.

    Or perhaps these would work.... looks like the adjuster nuts are right down the bottom of the rods.

    Thanks Magnum,

    Good info. I might have to look into machining the tops of my tubes if I can find someone who knows how to do it...
    I just can't work out why the aftermarket tubes are so expensive. Otherwise I'd haves just bought a set already.

    Sharp 5/8 drill bit and a steady hand will do it, one of mine rubs and because of the rocker lockers I can't push the support plate across a little to alleviate it, on the list of one day jobs.

    I have found using the S&S standard style pushrod in all applications the most stable. They are .437"ø compared to stock .375"ø, i have not found fouling in the cover an issue with these. Tapered pushrods are also good.
    The shorter the adjuster the more rigid the pushrod. Easy installs are just that, easy to install, the only real benefit is that you set the lifter at its optimal point but trade off rigidity. The old Crane adjustable pushrods were one of the best. The stock pushrod is very rigid as any one piece is, the problem with any fixed length is that the lifter set down is variable with stack up of tolerances and build, we have seen custom fixed length pushrods ride when cold to the point starting presents issues.
