What rockers do you like the best and why ?

Do not want to go with the cost of jessel so it is T+D or Harland sharp.

T&D with a bushing, not the bearing.

They'll make them, you just have to ask.

I have both and have had zero issues with either sets and I love the bearings in both

Love my T&D rockers. Why the bushing? I run the bearings

Are you wanting to buy the single shaft systems from both? If so either one will work, I've had and used both
I have two motors now with Harland Sharp 1.6 ratio and one set of heads with a set of T&D single shaft system with 1.7 ratio and another untested motor with Jesel 1.55 ratio paired shaft system on it
The motor with the Jesel rockers rotate a lot easier once broken away than any other motor I have built or tested
I am gathering parts now for a all out go fast motor with B1-MC heads and I will probally buy a set of the stainless steel(chrome moly maybe?) T&D 1.7 ratio paired rocker arm set up from them for this motor

Unless the HS setup is a lot less expensive and there's a budget issue, IMO the T&D is a better designed and machined rocker.

The T&D paired are the nicest rocker system I've ever used. Nice to be able to remove them a pair at time if needed. In my experience they will wear the shaft before they hurt a bearing. I replaced the bearings in mine last year. I have no idea how many passes they had before me but I'll bet they were somewhere around 1000. Cost $96 to replace all 32 bearings. All looked and felt fine. I had 3 shaft that showed brinelling. They were $25 a piece.

The short answer is never run a needle bearing on a reciprocating shaft. GM had a system so [censored] that the needle bearing was actually a step up. And the industry followed right along and the rest of us get the same garbage.

If you're going to run springs that are larger than about 1.580, and installed heights taller than about 1.950....... And the T&D system you're considering is the "single shaft" set-up, then you'll more than likely have to do some relieving of the rockers to clear the springs/retainers.

The HS rockers clear 1.625 springs with no issues.

If I remember right Harland Sharp will also clearance the rockers for more if asked to do so.

T&D will do a spring relief on the rocker arm as an option. I had that done on the T&D rockers for my Trick Flow heads.

I've used both T&D and Harland and there isn't any power difference between them. T&D rockers are smaller and lighter and work with pushrod oiling. The Harland rockers are big and beefy and designed to work with shaft oiling.

T+D hands down............ive broke HS with a solid flat tappet never any breakage with T+Ds

I have both and did break a HS once. It took about 700 runs though. I bought the T&D's for my -1 setup and haven't had an issue in three years. The LSM tool is golden for proper torque and adjustment.

Harland Sharp can be ordered with pushrod oiling and cup adjuster as an option at no extra charge. Just remember the HS do not come with mounting bolts or studs. T&D come with all mounting hardware. Best price for HS was found thru Don at FBO.

Thanks for all the input looking for the best in my budget regretfully paired rockers may be a little out of reach right now.

I was leaning toward T+D I have heard good about them I have also had good luck with harland sharp but never used them on 440-1 heads.

Thanks for the heads up on spring diameter. How they fit clearance and geometry wise was another question....

Now to price them.

I've owned and raced both T&D and Harland Sharp single shafts set ups on Indy heads, I'll buy another set of Harland Sharps for my next single shaft Indy headed motor build

As was posted on another site....
Quote "with all the steel rockers available today, why would anyone run aluminum?"

I'd also add why would any one run needle bearings. They are so 1977.

And which bushed steel rocker system do you recommend to use on the OP's Indy 440-1 heads?

He is probably stuck with aluminum but he could at least use a bushing instead of needle bearings.

I'd be surprised if Jesel didn't have something.


This is why no one runs chryslers. If someone made a steel rocker, would any one buy it? I doubt it. When I begged for a set of Norris stainless rockers people made fun of me.

Aluminum was only good for the manufacturers.


So, my point should have been if I ever do another race car, it will have other than a Chrysler in it. You can only cobble junk along so much and then you just say [censored] it.

No one runs Mopars. Give me a break and come to Ohio or Pennsylvania and see how many Mopars run at our tracks. Lol. And we run the crap out of our aluminum roller bearing lifters. 40 years and never broke an aluminum roller bearing rocker but I don't run crap either. Harland Sharp or t&d rockers for me
