KPALAG 2" Wide 4° Steel Leaf Spring Shims — 2-Pack Angle Correction, 1045 Steel with Electrophoretic Coating

KPALAG 2" 4° steel leaf spring shims are a two-piece set of 1045-steel angle-correction shims designed to adjust axle or driveshaft angle by 4 degrees for improved alignment and load distribution.

When your leaf-spring suspension or axle geometry needs a small, precise adjustment, these KPALAG shims offer a simple mechanical solution. Manufactured from medium-carbon 1045 steel and finished with an electrophoretic coating, the shims resist corrosion and hold up under repeated service. Each shim measures 2 inches wide and is intended to tilt the axle or driveline mounting by 4°, helping restore factory-ish angles after lifts, repairs, or worn components.

How will these shims change my axle or driveshaft angle?

Installing one or both shims under the leaf spring perch or axle seat subtly rotates the mounting point, shifting the axle pinion/drive flange through a 4° angle per shim. This small correction can bring a misaligned driveshaft or asymmetrical pinion angle back into a safer operating range without replacing original suspension parts.

• Each shim provides a 4° angular correction at the mounting surface.
• 2" shim width fits common leaf spring perches and mounts.
• Use one shim for minor adjustment or stack both for larger corrections.

What are these shims made of and how durable are they?

KPALAG shims are laser-cut from 1045 medium-carbon steel, which balances strength and toughness for suspension use. An electrophoretic finish improves corrosion resistance so the shim retains integrity and fitment under road and weather exposure.

• 1045 steel gives high tensile strength and reliable hardness.
• Electrophoretic coating resists rust and extends service life.
• Precision thickness maintains consistent angle correction under load.

How simple is installation and what tools are required?

Installation is straightforward: raise the vehicle, support the frame, and separate the leaf spring and axle mount enough to insert the shim. A basic jack, jack stands, and common hand tools are usually all that’s needed; no welding or fabrication is required.

• Use a jack to lift and create clearance at the mount.
• Loosen fasteners, slide in the shim, then retorque hardware to spec.
• Check alignment and driveline angles after installation.

Will these shims fit my vehicle and what is included?

These universal shims are intended for leaf-spring and axle-seat applications where a 2" wide shim can be accommodated; verify fitment against your perch width and bolt pattern before purchase. The package contains two 2" wide, 4° steel shims so you can correct one side or both sides of the axle as needed.

• Package: 2 × 2" wide, 4° angle steel shims.
• Universal design for common leaf spring/axle mount geometries.
• Confirm physical dimensions and clearance on your vehicle before fitting.

Who this is for: KPALAG 2" 4° steel leaf spring shims are aimed at mechanics, off-road enthusiasts, and DIY owners who need a compact, economical way to adjust axle or driveshaft angle after lifts, suspension repairs, or to correct subtle misalignment. They’re suited for vehicles with leaf springs or similar perch-mounted axles where a 2" shim can be safely installed. If you need precision angle correction without replacing major components, these corrosion-resistant steel shims provide a durable, reversible option.
