The best leaf spring shackle lift kit depends on your vehicle and the lift range you need. The maXpeedingrods kit is a direct-replacement option for 1987–1995 Jeep Wrangler YJ models, while adjustable kits serve select classic-car applications. For custom projects, Fanmao offers universal shackles, but fit must be checked against spring width and bolt size. Compare the listed fitment and adjustment range before choosing; a shackle that does not match your suspension is not the right kit.
| Product | Best For | Listed Lift Or Design |
|---|---|---|
| maXpeedingrods | 1987–1995 Jeep Wrangler YJ | 1.25-inch front and rear |
| REVOTUNE | Select Chrysler A-bodies | Three positions; 1–4 inches |
| Fanmao | Custom projects | Universal; verify dimensions |
| YANGCAN | Select Ford and Mercury models | Three positions; about 1–4 inches |
| McBay Performance | Select Camaro, Firebird, and Nova models | Four positions; 1–4 inches |
maXpeedingrods 1.25-Inch YJ Lift Kit

This kit is designed for 1987–1995 Jeep Wrangler YJ models with 2WD or 4WD. It provides a stated 1.25-inch lift at both the front and rear. The steel shackles are described as direct replacements, with precision machining and a silver powder-coated finish intended to help resist oxidation, corrosion, and rust.
Best for: YJ owners seeking a model-specific replacement shackle set with a modest, matching front-and-rear lift. The listed clearance benefit may help when upgrading to larger tires or rims.
Limitation: The stated fitment covers the Wrangler YJ years listed, not other Jeep generations. Confirm the vehicle year and configuration before ordering.
REVOTUNE Adjustable Chrysler A-Body Kit

REVOTUNE lists compatibility with select Chrysler A-body cars, including Dodge Dart, Demon, and Lancer, plus Plymouth Barracuda, Duster, Scamp, and Valiant models from specified years. Its rear shackles use heavy laser-cut steel plates and provide three lift positions, with an approximate 1-to-4-inch adjustment range. Stainless steel sleeves are included.
Best for: Owners of a specifically listed A-body who want to choose among multiple rear lift settings for stance or tire clearance.
Limitation: Compatibility is model- and year-specific. Check the full application list rather than assuming all Chrysler or Plymouth vehicles fit.
Fanmao Universal Adjustable Shackles

Fanmao describes this four-pack as universal rather than vehicle-specific. The shackles are made from 1/4-inch low-carbon steel and have a powder-coated finish. Listed dimensions are 9 inches long by 2 inches wide. The product information specifically advises checking spring width and bolt size before purchase.
Best for: Buyers working on a custom vehicle or trailer setup who can verify the shackle dimensions against their suspension.
Limitation: No particular vehicle fitment or lift height is listed. Do not treat “universal” as proof that the plates match your spring and bolt measurements.
YANGCAN Adjustable Ford And Mercury Kit

This three-position rear kit lists fitment for 1965–1973 Ford Mustang models with a 1/2-inch shackle bolt size and select Falcon, Mercury Comet, Cougar, and Montego applications. Its approximate adjustment range is 1 to 4 inches. The listed applications include exclusions, such as Falcon models other than wagons being specified for 1966–1970.
Best for: Owners of a listed classic Ford or Mercury model who want a selectable rear lift range.
Limitation: Bolt size and body-style restrictions matter. Verify both before purchase; the product is not presented as a universal classic-car kit.
McBay Performance Four-Position Kit

McBay Performance lists this rear kit for select 1967–1975 Camaro and Firebird models and 1962–1978 Nova applications. Its heavy-gauge steel plates have four adjustment positions and provide a stated 1-to-4-inch rear lift range. The kit also lists stainless steel sleeves and OE-style rubber bushings, and is described as manufactured in the USA.
Best for: Buyers with a listed application who want four height positions for more adjustment choices than a three-position design provides.
Limitation: The product is for selected models and years; confirm exact vehicle compatibility before ordering.
Buying Guide: How To Choose A Leaf Spring Shackle Lift Kit
Does the kit fit your exact vehicle?
Start with the vehicle’s make, model, year, and body style. Then check any listed details such as drivetrain or bolt size. A kit for a specific Mustang application, for example, should not be assumed to fit every Mustang. If the product is universal, measure the spring width and bolt size and compare them with the manufacturer’s specifications.
Do you need a fixed or adjustable lift?
A fixed lift can be a simpler match when the listed height suits your goal, as with the YJ kit’s stated 1.25-inch front and rear lift. Adjustable designs offer multiple mounting positions; the products here list approximate ranges of 1 to 4 inches. Select a setting based on the intended stance or clearance, and verify the vehicle-specific application.
What construction and finish are listed?
Compare the stated material and finish rather than relying on broad labels. These listings describe steel or low-carbon steel plates and finishes such as powder coating or zinc coating. The details can help you distinguish products, but they do not replace fitment checks or confirm suitability for every use.
Can shackles guarantee tire clearance?
Shackle lift listings describe added clearance or the ability to accommodate larger tires, but the information provided does not establish clearance for every tire and vehicle combination. Check the full suspension setup and the product’s application details before choosing a tire size.
Frequently Asked Questions
What does a leaf spring shackle lift kit do?
It replaces or changes the shackles that connect a leaf spring to the vehicle, with the listed kits intended to raise the vehicle or adjust rear height.
Are adjustable shackles universal?
No. Some are listed for particular vehicle families, while others are sold as universal. For universal shackles, verify spring width and bolt size before purchase.
How much lift do these kits provide?
The products in this selection list either a 1.25-inch front-and-rear lift or adjustable rear ranges of approximately 1 to 4 inches. Check each product’s fitment and adjustment details.
Why does bolt size matter?
The shackle bolt must match the suspension application. The YANGCAN listing, for example, specifies a 1/2-inch shackle bolt size for its Mustang fitment.
