[CSXT802]

Anyone use Aluminum valve spring retainers on there heads.? I'm getting parts together for my cam swap. I have a set of the 061 valve springs. I'm waiting for my F-3 cam to ship out. I just ordered up a set of mopar performance 2.2/2.5 Aluminum valve spring retainers . Has someone used these retainers before.?

Sorry it has been too long since I ordered the titanium ones. I think they were in the MP catalog though.

I looked up the titanium ones they are NS1. There were still Aluminum ones left. So I ordered up a set.

So are these good to use or not. Someone on TD replyed with this "Aluminum valve spring retainers are kinda known for splitting in half or pulling through. Most engine builders won't use them"

You got a picture of them? I just looked and the ones I have on the shelf are the Chrome Moly ones, but I have different ones in the car.

You can still buy the Ti ones, I was going to but the price stopped that. I was told not to use al ones on a street car, they will wear out or pull thru. The chrome moly ones weigh the same as stockers so no point getting those.

That was me

I was an automotive machinist for 20 years specializing in cylinder heads

Use the stockers, chrome moly or titanium.

The aluminum retainers work very well as spacers for engine stand bolts

Why would you risk your engine?

they have them all available here still in Canada, but when I asked for price on the Ti my jaw dropped!!! I wouldnt dare use aluminum, too soft and will be all mushed up after a few thousand K

What was the price? I got them like 5 years ago. I think they were $11 each or something from memory but I could be way off...

Steve M. suggested not to use Aluminum, and he is the expert!!

The dampeners in the springs will chew their way right through the aluminum. Go with steel or titanium.

[CSXT802]

Well that was money wasted. They will be something shinny on the shelf.

The Ti retainers from Dodge are like $28 each. Steve M has a kit for around $100 I think.
