Part # Main Caps

[Mike from Jersey]

I've looked everywhere and can't find the Part # for the SYTY main caps. Can anyone help me out?

Thanks,
Mike

do you have the part #'s for the 4 bolt caps (while were on the subject) Did u just do the center caps or the front and rear main also?

Here's a few PNs:

- Milodon Splayed 4 Bolt Main Caps - 11160
- CAT Ductile Iron 4 Bolt Main Caps (Conv) - MB350-4B
- CAT Billet Steel 4 Bolt Main Caps (Repl) - MB-350SR
- CAT Billet Steel Splayed 4 Bolt Main Caps - MB-350SS
- CAT Billet Steel 4 Bolt Main Caps (Conv) - MB350SW

Repl = Replacement 4 Bolt Cap (non-converting and not splayed)
Conv = Converts 2 Bolt to 4 Bolt

I cannot vouch for the CAT caps, as I have never used them, but I have used other stuff from them and it all seems "well worth the money". CAT stuff will be substantially cheaper (price wise) and that may reflect it's quality somewhat. Point? When building a 9/10 sec engine, you may wanna use something that's proven. But for the budget racer and someone not looking to set a new record, they are awfully appealing for the price (about $20 for the Ductile set and $70 for the Billet Steel sets).

Somebody will chime in with other numbers here I'm sure, but that's all I have at my disposal at this moment.

does any one make a steel rear cap i am doing a 4 bolt and would like to do the rear one too thanks

IMO the stock rear main cap is good with most builds. I wouldn't worry about it considering how they are made. Do a little research and you'll find them.

yes you can get a steel real cap. but it's still 2 bolt and cost is ~$250.
