Picture this: you're deep into an engine rebuild on your LS1 or LS6-powered truck, and the fuel injectors just won't seat right in the intake manifold. Frustrating, right? That's where the X AUTOHAUX 8pcs Fuel Injector Spacer Set comes in. These precision-machined spacers are designed specifically as replacements and adapters for LS1 and LS6 truck applications, ensuring a snug, leak-free fit every time.
Stock manifolds on GM LS engines often require spacers when swapping to larger or aftermarket injectors. Without them, you risk poor sealing, fuel pressure drops, or even manifold damage. This set eliminates those issues by providing the exact thickness and tolerances needed for optimal injector alignment and o-ring compression. No more guessing or custom machining—just bolt on and go.
Each spacer measures precisely to maintain fuel pressure integrity, supporting everything from stock tunes to high-horsepower builds. Users report smoother idling, quicker throttle response, and better overall efficiency after install.
Whether you're refreshing worn injectors on a daily driver, upgrading to 36lb/hr units for towing, or prepping for a supercharger kit, these spacers make the job straightforward. I've used similar sets on my own '99 Silverado LS swap—installed in under an hour, and the engine fired up flawlessly with zero codes. Perfect for weekend warriors tackling DIY repairs in the garage.
Unlike generic adapters that warp under heat, X AUTOHAUX spacers hold up to 80psi fuel systems and extreme temperatures. They're a direct fit for truck-specific manifolds, saving you time and shop fees. Pair them with new o-rings for a complete refresh, and you'll extend injector life while maximizing flow.
Ready to sort your LS truck's fuel system? This 8pc set is your go-to for reliable, no-drama injector replacements. Engineered for performance enthusiasts who demand precision.
