I need to confirm the part numbers on the SLS Back Series Buckets if anyone has it. Doing my head-bolts to be safe and changing the buckets at the same time...
Thanks guys

The SLS Black Series buckets do NOT fit the C63. The regular SLS buckets do. Just had this confirmed by AMG Germany (see below).

From MB shop foreman: --->

Incidentally I got a response from AMG today regarding the lifters in your vehicle. They confirmed you have the SLS style buckets (which is what you want) and also confirmed that we cannot use the lifters from the Black Series engines in your engine.

makes no since, i know several people using them. i got the part numbers yesterday. I'm almost sure that Weistec also uses these. you mind if i called you?

mr747

THey do work weistec sell them for a c63

OP you can buy them from weistec for 2k

BLKROKT

You can get them (32) for $1k from OEdiscountparts.com

4ramin

thank you

Diabolis

Well, someone is obviously wrong - either Weistec or MB Germany. Will investigate. Thanks for the heads-up.

i think your mb tech is wrong

Diabolis

Quite possible - except that that would be the AMG tech in Germany that answered the query. Will look into it (and knowing my tech, he'll definitley find the answer even if he has to rebuild a perectly healthy engine to try it out).

mr747

its good to have a contact like this your a lucky man

its been used in many applications with no issues, dimensions match up. they are coated and lighter...

Germany will always say a part won't fit if it's not listed for the vehicle in the parts catalog. It's a simple case of liability.

I have seen an answer from a vendor in Germany saying that in order to complete the purchase from a dealer of the SLS black series buckets, one has to produce evidence that they work on a black series with a vin number.

This can be counter intuitive and easily dismissed, except I've seen this before in the Subaru world when trying to purchase the limited S204 series parts. There was in the parts software in that case a note for the vendor to ID the car before the sale.

I'm hoping this is wrong however for the black series because I hope to go this route with my buckets too.

Here is the VIN of one for sale, if all they ask is a VIN then you can always find one for sale to use WDDGJ7HB4DG015243

No VIN needed. I have 32 on the way. The dealership will always tell you they don’t fit. Buy your parts guy coffee maybe he’ll help you out.

I bought a single tappet and the micrometer says they’re the exact same dimensions. But, definitely not same when it comes to weight and innards.

Ask the dealer to put it in the system without a VIN assigned. Prices are supposed to go up, as per my parts guy.

As an aside, is there anybody on here with standalone BS tappets for upgrades and the expected gains (if any) when tuned?

BLKROKT

SLS BS tappets do not create any gains by themselves. You’d have to put in an entire SLS BS valvetrain to see any performance benefit, and nobody’s doing that or cares to measure the before/after.

go team

I searched a bit more and read the difference is about 500 rpms. Where in the BS it’ll handle 7750 vs 7250 in non-BS other than being much more robust and handling revs for days

deadlyvt

The gains are the tappets should last longer

go team

even when it shifts at 8000?

deadlyvt

that’s not from just tappets...wel maybe that car is but the cams are entirely different in the compared to the regular cams which start to fall off around 7000-7200 rpm
Wouldn’t be much point recon that high unless you are changing the camshafts to take advantage of it

BLKROKT

And valve springs, probably the valves themselves, camshafts, etc. Just because you have SLS BS lifters doesn’t mean your redline will be 8k. Nobody’s even been able to get the SLS camshaft tuning right. The M159 is very different.

go team

There are a few tuners that will raise the rev limiter and fuel cut off to 7500 for non p31 cars and to 7750 w the p31 optioned “when requested”. ‘Why do that?’ would be the question. My car is still stock and would be interesting to see how it’ll respond to a tune with a valvetrain overhaul using the tappets.

BLKROKT

Okaaayyyyyyy

go team

I know you’re no fan but if reliability of these comes with the added benefit of power gain then nothing wrong with curiosity! Lighter tappets may change the curve a bit sooner.

Also I posted the video above being redundant... Aka my sarcasm

I just want to point out, lighter parts will not change your powerband at all. Spending money on these only lightens your wallet and adds a coating. You could also coat your current ones and get the same result. These are only to counteract the damage that some have seen as a result of wear.

If you want to change your powerband you need parts that alter your VE, so the cams will do that, an intake manifold will do that etc...
