NO NEEDLES TO WORRY ABOUT!!!!

These new bushing LS trunion kits for factory LS rockers are shipping the 3rd week of January. Engineered to provide maximum lubrication to the trunion while also providing maximum load capabilities, the NEW bushing LS trunion UP-grade kits give the LS world piece of mind. The proprietary bushing material is fed with an oil channel at the 10 and 2 positions of the trunion. This channel constantly feeds oil to the bushing surface ensuring proper lubrication. The greater surface area will support 300X the load of what a needle will. Also there is NO CHANCE of needle bearings destroying the engine when using much more aggressive cam profiles with stock type rockers.

Kit includes the trunion, bushings and C-Clips and can be used with the stock rocker bolt.

Pricing will be set at 159.00 per kit. Contact SRD directly for ordering!

Awesome! I will be trying these out on my build for sure. I'll be calling for a cam anyhow.

Nice Martin! I'm interested to get a set for some testing!

How are these better than what is already available on the market?

I'm not an engineer. But to me it looks like less moving parts.
How does it work?
It just does😅

What kind of bushing material are you using? I like the idea..

Oh course they come out with a new one after I did mine a year ago

Realistically do you think if you did the trunion upgrade a year or 2 ago you need this?

Will these perform/last just as well in vehicles with a lot of idle time at low oil pressures? Seems like we are basically taking the lifter bearing/bushing consideration and moving it up top..though losing a rocker is not as catastrophic as losing a lifter.

Thanks

I like seeing new products on the market!

for the guys above... do a search and see how many people complain of the comp cam trunnion upgrade failing... I haven't seen one yet..

If you are getting quite serious with cam and spring pressures, I have a feeling aftermarket heads/rockers are also in the equation.

It is a nice alternative and look forward to the reviews!

Since the trunion is no longer encapsulated by needles, it's ability to handle higher pressure and friction from higher spring rates and engine speeds is greatly enhanced. With needles, the load isn't as evenly distributed as it is with a bushing. Thus its increased load capacity.

Just like when solid roller lifters started being made with a bushing instead of needles to better distribute load and handle more spring pressure, now we're taking that same thought process to the rocker arm. With a needle bearing design there will always be a high point of pressure since pressure isn't distributed as evenly, and pressure is placed on a few needles instead of all of the needles encapsulating the bearing. With a bushing, that load spreads out much more uniformly.

I'd like to know this as well. I understand that it might be somewhat proprietary, I'm not looking for an exact alloy, just something like "bronze".

Sorry guys, but the material is proprietary.

I can guarantee that this will be the best trunion upgrade on the market in terms of quality and bang for the buck.

Martin,
How's things?

I'm curious about the reliability testing done on this design?

When you speak of needles you are speaking of the stockers, right? The last trunion upgrade before this didnt have needles either, correct?

Ron,

Things are going good! Hope all is well with you on the other side of the country sir.

I will be giving a set of these to a few customers who are utilizing stock rockers currently with high lift, fast ramp rate and high spring pressure applications to see how they hold up.

My initial feelings on them are that they will be leaps and bounds better than anything on the market currently. Aside from CHE there are no other companies utilizing a bushing style trunion bearing design.

No, I am not.

Comp, BTR, Summit, TFS etc. all use needle bearings to encapsulate the trunion. At this time only CHE utilizes a bushing design to encapsulate the trunion.

I'm willing to be a guinea pig. I'm running the BTR 660 springs with the Tick stage 2 truck cam that I bought as a package from you when you still worked there.

Granted my car is not in running condition right now, but should be there in a few months tops.

Sent you a PM about these. Willing to buy a set of course but also willing to test them. About to pull the 6.0 and rebuild it. Already have a TU2 turbo cam and BTR 660 springs and Ti retainers. Turbo setup going for close to 1000rwhp on SBE.

You mean encapsulate the trunion

That's what I get for posting too quickly and not re-reading what I typed!

So, you claim to have the best trunion upgrade, but as a client - I'm unable to know what the "bushing" material is? I'm intrigued, but I don't install components in mine, or ANY high performance engine where materials are kept secret from the end user.

You can "guarantee" that you have the best trunion upgrade on the market, yet you cannot even disclose what a simple bushing is derived from??

Not trying to bash, I just don't get it.
