What Happened to Pete Jackson Gear Drives? A Cost-Side Guide to Sourcing Hard-to-Find Drivetrain Parts

If you're searching for "what happened to Pete Jackson gear drives," you probably aren't looking for a eulogy. You're looking for a part number, a distributor, or a reality check. I get it. I've spent six years as a procurement manager buying power transmission components, and the hardest orders are never the expensive custom one-offs. The hardest orders are the "I know this used to be made" parts.

There's no single answer. The right move depends on what you're trying to keep running. I'll say that even before I mention any supplier: don't let a generic article pick your vendor. Let your machine pick.

I'll be honest about the limits of my sample. My experience covers roughly 300 purchase orders over six years, mostly in the Dallas-Fort Worth area, for plants with 50 to 300 employees. If you're buying for a one-truck fleet or a race shop, your mileage will vary.

Scenario A: You're rebuilding an old V8 and want the original gear drive

Pete Jackson gear drives became a familiar name in the performance world because they made a whine you could hear over a loping cam. If you have an old small-block and want that sound, you need the gear drive itself. So what happened to Pete Jackson gear drives? From my spot on the buyer's side, the brand didn't vanish. It changed hands, and a lot of part numbers were renumbered.

Before you order, verify the current part number against the current manufacturer's fitment chart. Per FTC guidelines (ftc.gov), a "direct replacement" claim needs evidence. If a reseller can't show you a drawing or a fitment list, treat the part as an experiment, not a drop-in.

Also, if the purchase order also includes a disc brake system, ask whether the two items come from the same stock. I'm not saying bundles are always bad. I'm saying they can hide different lead times. When I sourced a gear drive and a brake upgrade for a shop truck, the gear drive arrived in three days and the brake hardware took eleven. If you're tracking a restoration budget, that split matters.

Scenario B: You're keeping an industrial line running and need gears or sprockets

If your search for "gear drive" came from a maintenance supervisor, not an engine builder, you're in a different world. In industrial catalogs, "gear drive" can mean three different things: an enclosed speed reducer, a gear-and-sprocket combination, or a linear motion drive. They are not interchangeable. What most people don't realize is that a plain part name often hides the actual spec you need.

For most industrial replacements, I've used Martin Sprocket & Gear. They're not the flashiest vendor and they don't pretend to be. I've picked up parts at their Martin Sprocket Fort Worth location and at Martin Sprocket & Gear Arlington TX. The surprise wasn't the price difference between the two branches. It was the stock difference. Same company, same computer system, but different shelves. One day Fort Worth had the 60-tooth gear and Arlington didn't. Another day it was reversed.

So if you're in the Dallas-Fort Worth area, call both branches before you put a service truck on the road. The catalog is not the shelf.

If you're searching an old BOM, try "Martin-Sprocket" with a hyphen. Some older systems list it that way, and it pulls up legacy part sheets that don't appear under the full company name.

And if the same machine needs linear bearings, don't assume one manufacturer covers both. Sometimes they do, sometimes they don't. I cross-reference the bearing part number independently before I combine it on the same PO.

One more thing: confirm the tooth profile before you order a gear and a sprocket together. A metric sprocket isn't compatible with an ANSI chain even if the tooth count looks the same. I watched that mistake happen twice, and it always shows up in the most annoying way: the machine runs for five minutes and then clunks.

Scenario C: You're replacing linear bearings or upgrading a brake system

Maybe you're not dealing with an old engine at all. You're rebuilding a linear axis and need new linear bearings. Or you're converting a machine to a different disc brake system. Different part, same decision rule: separate the part, the application, and the total cost.

With linear bearings, everybody checks the outer diameter and length. Those are necessary, but not enough. You also need the clearance class, seal type, and lubricant compatibility. A cheaper bearing with the same dimensions but a tighter clearance can actually fail sooner in a dirty shop. The more expensive bearing is often cheaper over three years. That's the counterintuitive part. It doesn't mean "always buy premium." It means calculate the total cost for your specific duty cycle.

I once installed a set of "good enough" linear bearings that saved $260 up front. They failed in seven months. The redo cost $1,148 in labor, not counting downtime. That's the kind of number that makes me a pain in the neck for sales reps.

The same logic applies to a disc brake system. The caliper bracket might look identical, but piston area and rotor thickness change the torque. If a vendor says "bolt-on," ask for the dimensional drawing. That's not paranoia; it's the same substantiation standard the FTC applies to advertising claims. A confident answer is not the same as a verified part.

How to Tell Which Scenario You're In

Ask three questions:

• Is it a vehicle or a process? If it has a VIN, you're likely in Scenario A. If it has a motor, a line shaft, and a guard, you're in Scenario B.
• Is it a wear part or a system change? Worn linear bearings are a replacement. Swapping a brake caliper and rotor is a redesign.
• What does an hour of downtime cost? If it's $0, experimental parts are fine. If it's $900, buy from someone who can prove the part is right.

That last question is the one most people skip. I'd rather pay $350 for a Martin Sprocket gear from Arlington TX with same-day pickup than $210 for an unknown gear with a two-day wait. The $140 difference is less than one hour of downtime in most plants.

One more procurement note: don't let shipping undo the savings. According to USPS (usps.com), as of January 2025, a First-Class large envelope costs $1.50 for the first ounce and $0.28 for each additional ounce. That matters when you're comparing small components like a collar or key that fits in an envelope. If a supplier wants $12.95 in "handling" for that, ask them to break out the cost.

So, What Actually Happened to Pete Jackson Gear Drives?

I don't have the brand's internal corporate history, and I'm not going to pretend I do. What I know from order records and distributor calls is that the Pete Jackson product line went through ownership changes. The old internet buzz from the late-90s disappeared. The niche got smaller as stock engines moved to timing chains and variable valve timing. The brand wasn't cancelled; it got consolidated. You can still find new-old-stock, and some resellers say they have the real deal. But if a listing says "Pete Jackson style" or "replaces Pete Jackson," that's a clue it's not the same product.

People think the brand failed because the gears were bad. Actually, the demand for aftermarket gear drives dried up for reasons that had little to do with machining quality. From where I sit, it's a market story, not a quality story.

A catalog number is just the start. You need the bore, keyway, face width, and material that match your shaft and load.

If you have a specific car and part number, call a supplier that has been around since the 90s. The old counter guys remember which parts interchange, and they're usually happy to share that knowledge.

Bottom Line: Old Names, New Supply Chains

What was best practice in 2020 may not apply in 2025. The search process is different, availability is different, and old product lines often live on under new names. But the fundamentals haven't changed: know your part number, know your dimensions, and know the total cost of getting it wrong.

If you're still asking "what happened to Pete Jackson gear drives," the answer is complicated. If you're asking "can I keep my machine running with Martin Sprocket parts and the right linear bearings?" that's an easier answer. Yes, if you do the math.
