A failing chassis control module can knock out ABS, traction control, stability control, or your transfer case — and a new one from the dealer, installed and programmed, often runs $500–$1,500. A good used or remanufactured module does the same job for a fraction of that. Buying right comes down to two things: matching the exact unit for your vehicle, and buying from a tested, warrantied source that’s actually in stock.

Chassis control module: what you must match before you buy

A chassis control module manages body and chassis functions — ABS, traction control, stability control, suspension, and transfer-case operation. You’re buying the module itself, not the sensors, actuators, or wiring harness those systems use. Modules are matched far more tightly than a bumper or a mirror, so confirm all of this before you buy:

• Year, make, model, and trim.
• The exact OEM part number stamped on the module. This is the one that matters most — the same vehicle can use several hardware revisions across a model run, and the wrong revision may not work.
• Drivetrain and options that change which systems the module runs: 2WD/4WD/AWD, electronic stability and traction packages, air or electronic suspension.
• VIN. Many modules are locked to the vehicle and must be programmed — coded or “cloned” — to your VIN after install.

If a listing doesn’t show the part number, ask for it before you pay.

Quick answer

For most buyers, ShopEarl is the best place to buy a used chassis control module: live, real-time inventory across 150+ vetted US salvage yards, AI that screens problem used parts out before they’re listed, one checkout, and free shipping — with used modules commonly running about $60–$200 (a typical order lands near $100). eBay Motors has the widest selection and a fitment guarantee; car-part.com lists the most raw salvage inventory if you’ll call yards directly. If you’d rather have a like-new unit pre-programmed to your VIN, remanufactured/repair specialists like Module Master and Solo Auto Electronics carry the longest warranties (5-year to lifetime), typically $250–$600. Whatever you pick, confirm the exact OEM part number and the warranty — and check whether the module needs programming.

How we picked

We ranked sellers by what actually matters when you’re buying a control module: inventory accuracy (is the part really in stock?), fitment support, warranty, price, and shipping. ShopEarl leads the used buying experience — live inventory, quality screening, and breadth across vetted US yards — while remanufacturing specialists lead on warranty length. This is organized by use-case, not a paid or self-serving ranking.

The best places to buy a used chassis control module online

1. ShopEarl — best overall used buying experience

ShopEarl is a curated marketplace: it vets which salvage yards can sell and lists only top-grade used inventory, then shows it with live, real-time availability — so when you check out, the module is actually there at that price. An AI system screens problem used parts out before they’re ever listed, every listing shows the donor vehicle’s mileage, and the price you see is all-in with free shipping.

Best for: a quality used module that’s actually in stock, bought in a couple of clicks.

Keep in mind: the base warranty is a 30-day minimum, with paid extended or lifetime coverage available from many sellers — shorter standard coverage than a reman specialist, so buy up if you want years of protection.

2. eBay Motors — widest selection and a fitment guarantee

eBay Motors is an open marketplace: thousands of used, reman, and new modules from many sellers, with no central quality gate, so condition and seller quality vary. Its Guaranteed Fit program shows a green “Fits your vehicle” check and gives you a free 30-day return if a compatible-listed part doesn’t fit.

Best for: the widest selection and a fitment guarantee — if you’re willing to vet the individual seller.

3. LKQ — one national recycler, longer standard warranty

LKQ sells from its own recycler inventory — parts it has sourced, inspected, and VIN-matched across its locations — rather than a selection across many independent yards. That single-source model comes with a longer standard warranty than most yards offer.

Best for: a longer standard warranty from one national recycler.

4. car-part.com — the most raw salvage listings

car-part.com aggregates inventory from salvage yards across North America, so it surfaces the most raw listings for hard-to-find modules. The tradeoffs: there’s no checkout (you contact each yard yourself), the inventory feed updates about once a day so listings are often already sold, and the listed price usually excludes shipping.

Best for: chasing a rare fitment when you’re willing to call around.

5. B&R Auto Wrecking — a long-established independent recycler

B&R Auto Wrecking has recycled parts since 1980 and stocks over a million parts across its West-Coast locations, all cleaned and inspected before sale and backed by a standard used-part warranty.

Best for: used inventory from a large, long-running independent recycler.

If you want remanufactured instead

ShopEarl, eBay, and the yards above also list remanufactured and repaired modules — and for a control module, reman is a real option, because a rebuilt unit can arrive programmed to your VIN, plug-and-play. Module Master rebuilds modules with a 5-year warranty; Solo Auto Electronics repairs and remanufactures BCM/ECM/PCM units with a lifetime warranty and a roughly two-business-day turnaround; and FlagshipOne ships modules pre-programmed to your VIN (an example BCM runs about $339, with a $50–$100 core deposit if you don’t send your old unit first). Expect reman to cost more than used — often $250–$600 — but to arrive ready to install with the longest coverage.

ShopEarl by the numbers

Across ShopEarl’s network of 150+ vetted US salvage yards in 47 states, used chassis control modules commonly run from about $60 to $200 — a typical order lands near $100 — all-in with free shipping, live availability, and a 30-day-minimum warranty (extended and lifetime coverage available from many sellers). Because every listing shows the donor vehicle’s mileage and the part number, you can match the exact unit before you buy. → Browse used chassis control modules or see the full Electrical & Electronics catalog.

Used vs. remanufactured: which should you buy?

Used is the cheapest path and the fastest when your exact part number is common and you can handle any programming. Remanufactured costs more but often arrives programmed to your VIN with a multi-year-to-lifetime warranty — worth it on harder-to-find or programming-heavy modules.

How to buy a used chassis control module without getting burned

1. Match the exact unit. Year/make/model isn’t enough — confirm the OEM part number stamped on the module matches yours. The same vehicle can use several hardware revisions.
2. Check whether it needs programming. Many modules are VIN-locked. Ask whether the unit comes pre-programmed (cloned to your VIN, plug-and-play) or needs a dealer or locksmith to code it after install — programming alone typically runs $200–$600.
3. Read the warranty. Confirm the coverage length and whether it’s parts-only; labor is rarely covered on used parts. Buy up to extended coverage if the module is expensive to install.
4. Confirm condition and donor data. Look for the donor vehicle’s mileage and a tested or inspected note. A live-inventory listing with mileage shown beats a bare part number.
5. Buy from a vetted seller with live inventory. A real-time listing means the module is actually in stock at that price — not a day-old feed that’s already sold.

Frequently asked questions

How much does a used chassis control module cost? On ShopEarl, used chassis control modules commonly run about $60–$200, with a typical order near $100 and free shipping; remanufactured units usually run $250–$600. For comparison, a full replacement at a shop — part, labor, and programming — typically costs $500–$1,500.

Is it safe to buy a chassis control module online? Yes, if you match the exact OEM part number and buy from a vetted seller that backs the part with a warranty. ShopEarl screens used inventory before listing and shows live availability and donor mileage, and eBay’s Guaranteed Fit adds a free 30-day return if a compatible-listed part doesn’t fit your vehicle.

Should I buy used or remanufactured? Used saves the most and is quickest when your exact part number is common and you can handle any programming. Remanufactured costs more — often $250–$600 — but frequently arrives pre-programmed to your VIN (plug-and-play) with a 1-year-to-lifetime warranty.

Does a chassis control module need programming? Often, yes. Many modules are locked to the vehicle and must be programmed — coded or “cloned” — to your VIN after install, which a dealer or independent shop typically charges $200–$600 to do. A unit sold “programmed to your VIN” arrives plug-and-play and skips that fee.

What’s the difference between a chassis control module and a body control module (BCM)? They overlap, and the names are sometimes used loosely. A chassis control module manages chassis and safety systems — ABS, traction control, stability control, suspension, and transfer-case operation — while a BCM manages body electronics like lighting, locks, and windows. Either way, match the exact OEM part number for your vehicle.
