Brake Pads for Brembo Calipers, Jeep 4.0 Head Gasket Location & the S10060XL Oil Filter: 7 Questions We Actually Get

The questions below land in my inbox almost every week. Some are about specific part numbers - brake pads for Brembo calipers on a Dodge Charger, the S10060XL oil filter, a head gasket for a Jeep 4.0. Others are about how a metal parts plant actually handles a rush order when everything's on fire.

I coordinate urgent production at a precision metal forming company. In seven years I've handled 200+ rush orders, including same-day turnarounds for Tier 1 automotive clients. Here's what I actually say when people ask.

Questions in this FAQ

• Will standard brake pads for Brembo calipers fit a Dodge Charger 6-piston setup?
• Where is the head gasket located on a Jeep 4.0?
• Does the S10060XL oil filter fit my engine?
• Do you accept small orders, or is there a minimum?
• What does a real rush order look like?
• Why do you insist on checking part numbers instead of trusting the catalog?
• What standards do your parts actually meet?

1. Will standard brake pads for Brembo calipers fit a Dodge Charger 6-piston setup?

No - not unless the pad is listed for that specific caliper. Brake pads for Brembo calipers come in a lot of shapes. The Dodge Charger 6-piston Brembo brake pads, the fronts especially, are specific: distinct backing plate ears, a matched pad thickness, and a profile that sits correctly in that caliper body. A pad built for a 4-piston Brembo caliper won't seat properly in a 6-piston one.

When I first started handling brake hardware, I assumed a Brembo caliper meant a universal Brembo pad. It took one returned set with bent backing plate ears to teach me otherwise. What actually matters is the pad's part number, the backing plate profile, and the application listing. Not the logo on the dust boot.

We stamp backing plates for brake pads, and every plate we make is built to a drawing that matches a specific caliper design. That's the only way this works - and the only way to avoid discovering your new pads don't fit on a Friday afternoon before a track day.

2. Where is the head gasket located on a Jeep 4.0?

The Jeep 4.0 head gasket sits between the engine block and the cylinder head. On that inline-six, it's on top of the block, directly beneath the cylinder head, all the way under the valve cover. You can't see it without pulling the valve cover and unbolting the head. If you're asking where the head gasket is located, you're probably dealing with symptoms, not prevention.

Head gasket failure on these engines usually shows up as oil and coolant mixing, white smoke from the exhaust, overheating, or misfires on adjacent cylinders. The metal fire ring on a head gasket is stamped - it's one of the products we make - and when it fails, coolant goes exactly where it shouldn't.

The time factor matters here. I've watched more than one customer gamble fifty miles on a bad gasket. That's how an aluminum head warps. Get it parked. Get a proper diagnosis. Replacing the gasket is one budget; replacing the head is another.

3. Does the S10060XL oil filter fit my engine?

That number comes up a lot because it's all over cross-reference charts. The S10060XL oil filter is a spin-on design, and the XL generally means extended-life media. But - and this is where people get into trouble - the same filter number can be listed across multiple engine platforms, and an interchangeable part number doesn't automatically mean identical specs.

As of January 2025, the reliable check is physical: thread size (commonly M20 x 1.5 or 3/4-16 for domestic V8s), gasket inner diameter, and overall filter length. If those match your factory filter, the S10060XL will likely work. If the filter is too long, it can contact the subframe. Too short, and you're giving up filtration area.

What I mean is: trust the physical match, not the lookup chart alone. Thirty seconds with a ruler saves you an oil change mess. Oh, and buy from a source that will stand behind the part.

4. Do you accept small orders, or is there a minimum?

Yes. I used to figure a plant running progressive stamping presses wouldn't care about a $200 order. That was wrong.

We debated minimum order quantities more than once. On paper, MOQs make sense - setup time is setup time. But the math doesn't account for one thing: small orders are usually tests. The customer who orders 50 parts to validate a process is the same customer who orders 50,000 a year later. The vendors who treated my small orders seriously in the early days are the ones I still call for big ones. That's a principle, not a coincidence.

Small doesn't mean unimportant. It means potential. When I'm triaging a rush order, the order size doesn't change the urgency. A 200-piece stopgap matters just as much to the line it's keeping alive as a 20,000-piece production run.

5. What does a real rush order look like?

Not like a movie. It looks like an email at 2:17 PM on a Thursday:

“Progressive die cracked. Need 400 stamped shims by Monday. Possible?”

In March 2024, we had 36 hours to repair a die and run 500 parts for a supplier whose line restart carried a $50,000 penalty clause. Normal turnaround on that part was 10 days. We pulled the tool off its scheduled rebuild, cut the damaged station, and ran the batch overnight. We delivered with 44 minutes to spare.

But that's not the point of the story. The point is we do not promise a date unless the tooling and machine capacity actually exist at that moment. I've said no to rush orders. When I'm triaging, I give a yes or no based on the schedule that day, not on optimism. Looking back, the 48-hour buffer policy we adopted after a 2023 miss is the reason our yes still means something. It's already saved us twice.

6. Why do you insist on checking part numbers instead of trusting the catalog?

Because I've eaten that cost. Everyone told me to check the drawing before approving a run. I didn't - once. Six years ago, I trusted a catalog number for 200 backing plates and skipped the drawing check. The hole pattern was half a millimeter off. That mistake cost us $800 in rework, a late delivery to the customer, and nearly lost the account.

Now every order, rush or not, gets a drawing verification before steel gets cut. That extra step costs ten minutes. The skipped step costs $800 and a client. The math is not complicated.

Why does this matter to you? Because if you call in an emergency, the last thing I want is to produce the wrong part faster than you could've gotten the right one from a regular supplier. Fast and wrong is worse than slow and right. We've shipped a wrong part before. Not ideal. But we've never shipped the same wrong part twice.

7. What standards do your parts actually meet?

We build to the same quality system the Tier 1 brake and engine suppliers use: IATF 16949:2016, with PPAP documentation on production parts. That means drawing-controlled dimensions, material certifications, and batch traceability. If a part number changes, the PPAP gets re-reviewed - that's the process that catches mistakes before they become trends.

For the 6-piston Brembo brake applications we support, the relevant system-level standard is FMVSS 105 for hydraulic brake systems and FMVSS 135 for light vehicles. Those cover system performance, not just component dimensions. On the stamping side, we do CMM reporting and flatness checks on backing plates - a thin plate that isn't flat will make noise and wear unevenly, no matter how good the friction material is.

As of January 2025, that's the baseline. If you need material certs (SAE J403 for steel chemistry) or full test reports, ask before you order - not after the parts land on your dock.
