Supertech Valve Spring Shim 1.140in OD .570in ID .030in Thick (Drop Ship Only) - SS-3043

The Supertech Valve Spring Shim SS-3043 is a precision engine component measuring 1.140" outer diameter, .570" inner diameter, and .030" thick — designed for use by performance engine builders who need fine-tuned control over valve spring seat height and installed load. Many engine builders consider the valve spring shim an invaluable tool when tuning a performance engine, allowing them to precisely adjust spring pressure and coil bind clearance without replacing the entire spring set. If you're building or refreshing a high-performance engine and need a reliable, consistently dimensioned shim from a trusted name in valvetrain components, the Supertech SS-3043 belongs in your build kit.

Key Features & Benefits

• Precision Dimensions (1.140" OD / .570" ID / .030" Thick): Exact, consistent sizing is critical in valvetrain work — these shims deliver repeatable, known dimensions so you can calculate installed spring height with confidence rather than guessing.
• Invaluable Tuning Tool: As noted by performance engine builders, valve spring shims give you a practical way to correct installed height, restore proper spring seat pressure after a head resurface, or fine-tune valvetrain geometry during a performance build.
• From a Trusted Performance Brand: Supertech is a well-established name in the aftermarket engine components space, with a broad catalog of valvetrain hardware used in competition and street performance applications worldwide.
• Compact and Ready to Stock: At a low per-unit price point, it makes sense to keep several on hand during a build so you can dial in each cylinder without waiting on additional orders.
• In Stock and Ready to Ship: Unlike some specialty valvetrain components, the SS-3043 is a regularly stocked product at ThreePiece.us — no long waits on this item.

Fitment

The Supertech SS-3043 valve spring shim is a universal performance engine component — it is not vehicle-specific. Fitment is determined by your engine's valve spring pocket diameter and the valve stem/retainer dimensions, not by year, make, or model. The 1.140" OD and .570" ID define which spring seats and valve stems this shim is compatible with. Always verify your engine's spring seat diameter and confirm the shim OD will seat properly without contacting the spring coils before installing. If you're unsure whether the SS-3043 dimensions are correct for your specific application, our team is happy to help — contact us before ordering.

What's in the Box

This listing is for one (1) Supertech SS-3043 valve spring shim. If your build requires shims at multiple cylinders, order the quantity you need. Because shims are used to fine-tune installed height per cylinder, many builders order several at once.

Frequently Asked Questions

What does this shim do and why would I need it?

A valve spring shim is placed under the valve spring, between the spring and the cylinder head's spring seat, to adjust the installed height of the spring. This allows an engine builder to restore or set the correct installed spring pressure — for example, after a cylinder head has been resurfaced and material has been removed. Many performance engine builders consider this an essential tuning tool when assembling a high-performance valvetrain.

Is the SS-3043 compatible with my engine?

The SS-3043 is not application-specific — compatibility depends on your engine's spring seat diameter and valve stem size, not the vehicle. The shim measures 1.140" OD and .570" ID. You'll need to confirm these dimensions match your spring seat pocket and valve stem before ordering. If you're unsure, contact our team at 813-535-5801 and we'll help you verify fitment.

How many shims come in this listing?

This listing is for one (1) individual shim. If your engine build requires shims at multiple valves or cylinders, simply adjust your quantity at checkout. Since installed height can vary valve-to-valve, many builders order extras to have on hand during assembly.

How long will it take to receive my order?

The SS-3043 is a regularly stocked product at ThreePiece.us — it is not a special order item. Orders ship with free shipping on every order. For specific delivery timeframes, refer to our shipping policy or contact our team directly.
