A used 5.7 Hemi engine assembly runs about $3,050–$4,150 on ShopEarl (July 2026); a remanufactured long block costs more but adds a multi-year warranty. Whether you drive a Ram 1500, Charger, or Challenger, buying the right one comes down to matching fitment and choosing a tested, warrantied source.

What a 5.7 Hemi engine is — and what to match before you buy

The 5.7L Hemi (345 cubic inches) is Chrysler’s third-generation Hemi V8, found in the Ram 1500 and 2500, Dodge Charger, Challenger and Durango, Chrysler 300C, and Jeep Grand Cherokee and Commander. An engine assembly is the complete long block or short block — cylinder block, heads, pistons, crankshaft, camshaft, and valvetrain. It does not include the intake or exhaust manifolds, alternator, power steering pump, AC compressor, sensors, wiring harness, or mounts, so plan to transfer those from your original engine.

Match these before you buy:

• Year, make, model and the VIN 8th digit (engine code) — this pins the exact application.
• Generation. The 2003–2008 Hemi has no variable valve timing; the 2009-and-up “Eagle” adds VVT and, on many versions, MDS cylinder deactivation. The two generations are not interchangeable.
• Truck vs. car. Ram truck Hemis differ from Charger, Challenger, and 300 car Hemis in intake manifold, oil pan, and accessory drive — a truck engine is not a drop-in for a car.
• Donor mileage. ShopEarl shows the donor vehicle’s mileage on every used listing, so you can weigh wear before you buy.

Quick answer

For most drivers, a tested used 5.7 Hemi from a vetted yard is the best value: on ShopEarl, used 5.7L Hemi engine assemblies list from about $3,050 to $4,150 (July 2026), with donor mileage shown, free shipping, and a 30-day-minimum warranty (extended or lifetime coverage available from many sellers). Two strong used alternatives are eBay Motors (widest selection, Guaranteed Fit) and LKQ (one national recycler, longer standard warranty). If you want the longest hands-off coverage, a remanufactured long block from JASPER carries a 3-year/100,000-mile parts-and-labor warranty. Always confirm fitment (VIN engine code plus generation) and read the warranty before you buy.

How we picked

This list is organized by buyer use-case, not a forced ranking. We weigh warranty, price, selection, fitment support, shipping, and inventory accuracy. ShopEarl leads the used buying experience — live inventory, vetted US yards, and a single checkout — while remanufacturing specialists like JASPER lead on warranty length. We say both plainly, because an honest comparison is the useful one.

The best places to buy a 5.7 Hemi engine online

Best for used

1. ShopEarl. A curated marketplace: ShopEarl vets which salvage yards can sell and lists only top-grade used inventory, with live, real-time availability and an AI system that screens problematic used stock out before it’s listed. You get one checkout, free shipping, and donor mileage on every listing. Best for: a quality used 5.7 Hemi engine that’s actually in stock, bought in a couple of clicks. Keep in mind: the base warranty is a 30-day minimum — shorter than a reman specialist’s multi-year standard coverage — but many sellers offer paid extended or lifetime coverage.
2. LKQ. Sells from its own recycler inventory, sourced and VIN-matched across its national network, typically with a longer standard warranty than a bare used part. Best for: a longer standard warranty from one national recycler.
3. eBay Motors. An open marketplace where anyone can list, so condition and quality vary seller to seller; the Guaranteed Fit program helps with fitment. Best for: the widest selection and a fitment guarantee, if you’ll vet the seller.
4. car-part.com. The widest raw listing database, but there’s no checkout (you contact each yard), the feed refreshes on a daily cycle so listings are often already sold, and prices exclude shipping. Best for: chasing a rare fitment if you’re willing to call around.

Best for remanufactured

5. JASPER. Remanufactured gas engines built to updated specifications, most covered by a 3-year/100,000-mile nationwide parts-and-labor warranty. Best for: the longest hands-off warranty and installed-anywhere coverage.
6. Powertrain Products. An established remanufacturer that ships engines and transmissions directly to you, backed by a multi-year warranty. Best for: a remanufactured long block delivered to your door.

ShopEarl by the numbers

Across ShopEarl’s 150+ vetted US salvage yards in 47 states, used 5.7L Hemi engine assemblies for common Ram 1500, Charger, and Challenger applications list from about $3,050 to $4,150 (July 2026), with donor mileage shown on every listing — in-stock examples today run roughly 97,000 to 185,000 miles. Every order includes live availability, free shipping, and a 30-day-minimum warranty, with optional coverage up to lifetime.

Used vs. remanufactured: which should you buy?

A used 5.7 Hemi engine is a running engine pulled from a donor vehicle, tested and sold as-is with mileage disclosed — the lowest price and, from a vetted source, a proven unit. A remanufactured 5.7 Hemi engine is disassembled, machined, and rebuilt to specification with new wear parts — higher price, but a like-new internal build and a much longer warranty.

Buy used when budget matters, you can match a solid low-mileage donor, and you or your shop can install it. Buy remanufactured when you want the longest warranty and a rebuilt-to-spec engine, and the extra cost is worth the peace of mind. If you’re cross-shopping a GM truck instead, our 5.3 Vortec used-vs-reman guide walks the same tradeoff, and the used-engine buying guide covers sellers across every make.

How to buy a used 5.7 Hemi without getting burned

1. Match the exact unit. Confirm the VIN 8th-digit engine code, the generation (pre-2009 vs. 2009-and-up Eagle/MDS), and truck vs. car — they are not interchangeable.
2. Check donor mileage and condition. ShopEarl lists mileage on every used engine; favor a lower-mileage donor with a clean description.
3. Read the warranty. Know whether it covers parts only or parts and labor, and for how long. Used base coverage is short; reman is multi-year.
4. Ask about the core charge. Many engines require you to return your old core, which affects the true price.
5. Buy tested, from a vetted, live-inventory source — so the engine is actually in stock and was screened before it shipped, not sitting stale on a once-a-day feed.

Replacing the transmission at the same time? It’s often smart on a high-mileage truck — price both before you commit. Browse more guides on the ShopEarl blog.

Frequently asked questions

How much does a used 5.7 Hemi engine cost? On ShopEarl, used 5.7L Hemi engine assemblies list from about $3,050 to $4,150 (July 2026), with donor mileage shown on each listing. A remanufactured long block costs more — typically $4,500 to $7,000 or more — but adds a multi-year warranty (JASPER covers most engines 3 years/100,000 miles). A full engine swap installed at a shop often runs $5,000 or more once labor is added.

Is it safe to buy a used 5.7 Hemi engine online? Yes, if you buy a tested engine with the donor mileage listed, a warranty, and confirmed fitment. ShopEarl screens problematic used inventory out before it’s listed and shows live availability and donor mileage, so you can buy knowing the engine is actually in stock. Confirm the VIN engine code and generation match your vehicle.

Used or remanufactured 5.7 Hemi — which should I buy? Buy used to save money when you can match a good low-mileage donor and handle installation. Buy remanufactured when you want the longest warranty (JASPER’s 3-year/100,000-mile parts-and-labor coverage) and a rebuilt-to-spec internal assembly, and the higher price is worth the peace of mind.

What is the “Hemi tick,” and does it mean I need a new engine? It’s the ticking of a failing MDS hydraulic lifter, most common on 2009-and-up Eagle engines around 100,000 miles. Caught early, replacing all 16 lifters and the camshaft may fix it (commonly $2,000–$5,000). If the cam lobes or bearings are already damaged, a used or remanufactured engine assembly is usually the better value.

How long will a used 5.7 Hemi last? A well-maintained 5.7 Hemi engine commonly runs past 200,000 miles. With a used engine, start with a donor at reasonable mileage, then protect it with regular full-synthetic oil changes — the low-RPM lifter wear behind the “Hemi tick” is linked to oil breakdown.
