Generic LS ECM Mounting Bracket CNC-Cut Stainless for GM 0411/LS1B PCM – Two-Piece Corrosion-Resistant Mount

This CNC-cut stainless steel mounting bracket securely holds GM 0411/LS1B style engine computers for LS swaps, simplifying placement and eliminating clearance headaches.

When converting an older truck or custom project to an LS platform, accurate and sturdy ECU placement is crucial. This two-piece Generic LS ECM mounting bracket is engineered to accept the common 99–06 GM 24x 0411/LS1B style PCM bodies (red/blue or green/blue connectors). Made from cold-rolled stainless sheet with an anodized finish, the pair of brackets give you a repeatable, corrosion-resistant means to fasten the computer to any flat surface during swaps or restorations.

How does this bracket make an LS swap easier?

The bracket standardizes how the ECM attaches so you don’t have to fabricate a custom mount each time. It saves trial-and-error fitting, reduces adjustments under tight clearances, and lets you position the computer in an easily serviceable location.

• Fits common GM 0411/LS1B 24x ECM body shapes used on 1999–2006 LS engines.
• Mounts to any flat surface for flexible placement inside the engine bay or cab.
• Two-piece design holds the ECM firmly while allowing straightforward removal.
• Helps avoid interference with headers, firewall, or other swap components.

What materials and construction features ensure long-term use?

These brackets are laser/CNC cut from 1.5 mm cold-rolled stainless steel and receive an anodic oxidation finish for improved corrosion resistance. The sheet thickness balances strength with formability so the bracket won’t flex or fatigue in normal service.

• 1.5 mm cold-rolled stainless steel resists rust and supports the ECM weight.
• Anodic oxidation surface treatment reduces corrosion and visual wear.
• Precision cutting ensures consistent hole alignment for four mounting screws.
• Durable edge quality minimizes chance of sharp burrs during handling.

Which ECMs and vehicles will this bracket work with?

The kit is intended for GM LS family computers that share the LS1B / 0411 body shell—commonly found on LS engines from 1999 through 2006 with the 24x two-connector PCM. It’s a universal-style mount for swaps into trucks, muscle cars, or custom builds including C10s.

• Compatible with LS1B / 0411 style GM PCMs (red/blue or green/blue 24x connectors).
• Works for 5.3L, 6.0L, LQ9, LM7 and other LS platform engines where that body is used.
• Designed for retrofit projects such as classic C10 conversions and engine swaps.
• Not a direct-fit electrical harness—only a mechanical mounting solution.

How do I install the ECM bracket and what hardware do I need?

Installation is straightforward: position the bracket against the ECM body and attach using four small screws through the provided holes. Hardware is not included, so pick screws compatible with the ECM’s threaded inserts and your mounting surface.

• Requires four small screws (user-supplied) to secure bracket to ECM body.
• Attach bracket assembly to any flat structure using appropriate bolts or rivets.
• Check alignment with harness routing to prevent connector strain.
• Use anti-seize or thread locker as appropriate for vibration-prone locations.

Who is this for: This two-piece Generic LS ECM mounting bracket is aimed at DIY mechanics, professional shops, and custom builders performing LS swaps who want a reliable, off-the-shelf way to mount 0411/LS1B style PCMs. If you need a repeatable, corrosion-resistant mounting solution that reduces fabrication time and keeps the computer accessible for tuning and service, this kit provides a simple, robust answer.
