A single piece of hardware is often the most critical component in an engine rebuild, and overlooking it can lead to catastrophic failure. While it might feel tempting to reuse old hardware, GM specifications strictly require a fresh balancer bolt every time the crankshaft pulley is reinstalled. This Michigan Motorsports bolt provides that essential peace of mind by serving as a genuine OEM replacement. It is manufactured right here in the USA, ensuring it meets the rigorous standards required for Gen 3, 4, and 5 series engines. Installation is straightforward and requires no specialized tools, making it a simple but non-negotiable addition to your parts list when working on LS or LT platforms. Just keep in mind that this specific bolt is not intended for LS7, LS9, LT4, or LT5 engines.

Precision engine building requires much more than the standard off-the-shelf bearings that most hobbyists settle for during a rebuild. The Michigan Motorsports CH-10 set is specifically engineered for 1997-2003 1st Gen LS1 engine blocks, utilizing a seamless steel tube construction that completely eliminates the risk of surface interruptions or breakage during installation. By using a lead-based babbitt material, these bearings offer superior embedability and anti-seizure characteristics that protect your engine from the catastrophic failures often caused by harder, less conformable materials. The centerless ground design is incredibly impressive, maintaining wall variations of just .0004 inches to ensure you are working with the tightest tolerances available in the industry today.

Swapping LS1 style heads onto an LS-series engine often hits a wall when you realize the geometry just doesn't line up. This Michigan Motorsports conversion kit solves that headache by providing the specific 1.7 offset intake rocker arms required for LS3, L76, L99, and LS9 head configurations. Instead of hunting down individual components, you get a complete package containing eight genuine GM LS3 rocker arms, two dedicated rocker arm stands, and sixteen new trunnion bolts.

For under ten dollars, you are getting a specialized solution that covers nearly every Gen 3 and Gen 4 LS engine produced between 1997 and 2013.

Michigan Motorsports has engineered a vital insurance policy for your LS engine by replacing notoriously unreliable factory components with these professional-grade LS3 rocker arms. Stock needle bearings are a ticking time bomb that can shed metal debris throughout your entire engine, but this kit swaps that vulnerability for a heavy-duty 8620 steel alloy trunnion and caged roller bearing setup. These rockers feature an offset fulcrum specifically designed for square port heads like the L99 and LS9, making them a cornerstone upgrade for anyone running an aggressive cam profile. It is the exact same hardware used in their 1,000 hp turbo builds, providing peace of mind that your valvetrain can handle high-performance demands without the risk of catastrophic failure.

After weeks of high-RPM testing, the peace of mind provided by this Michigan Motorsports kit is impossible to ignore. Standard LS engines are notorious for needle bearing failures that can devastate an entire motor, but this upgrade completely eliminates that anxiety. By replacing the flimsy OEM powdered metal trunnions with premium 8620 steel alloy and caged roller bearings, you transition to a true roller setup that handles aggressive cam profiles with ease. This isn't just a budget fix. It is the exact hardware used in 1,000 hp turbo builds. The inclusion of chromoly pushrods and all necessary allen head bolts makes it a comprehensive solution for anyone running anything from a stock 5.3 to a highly modified 6.0 engine.

Standard engine builds often settle for mediocre tolerances that invite premature wear, but the Dura-Bond CH-25 changes the math for LS enthusiasts. These bimetal bearings utilize a seamless steel tube construction coated in a lead-based babbitt, which effectively eliminates the surface interruptions and breakage common with lesser alternatives. What really stands out during installation is the precision. The centerless ground OD and bored ID result in incredibly tight wall variations of just .0004 inches. This level of machining provides the conformability and anti-seizure characteristics necessary to prevent engine failure under high-stress conditions. Whether you are upgrading an LS3 or maintaining an LSA, these bearings offer a professional-grade solution that replaces the older CH-23 standard with superior embeddability.

Michigan Motorsports has delivered a definitive fix for Ford owners struggling with failing illumination components. This socket serves as a direct replacement for the popular license plate lamp housing, specifically designed to resolve issues with turn signals, parking lights, or marker lamps. It is engineered to accommodate both 194 and 921 bulbs, providing versatile options for your lighting setup. While the unit does not come with the bulbs themselves, the build quality ensures a reliable connection for your brake, reverse, or marker lights. It is a highly specialized part that fits a massive range of applications beyond what is listed in the standard charts, making it an essential spare for any Ford enthusiast looking to maintain factory-standard visibility.

Most engine builders settle for standard hydraulic lifters that can't handle high-performance demands, but these Michigan Motorsports LS7 lifters provide the durability required for serious LS builds. This set of eight hydraulic roller lifters is a versatile upgrade that fits a massive range of GM applications, including the 4.8, 5.3, 5.7, 6.0, and 6.2 liter engines. What makes this set particularly interesting is its adaptability. It isn't strictly limited to LS platforms and can actually work in SBC and LT1 applications that originally utilized hydraulic roller lifters. At a price point, you are getting a reliable component that bridges the gap between budget builds and high-performance racing setups. It is a straightforward, essential piece for anyone looking to stabilize their valvetrain performance.

The cold, raw texture of CNC-machined aerospace-grade aluminum immediately signals that these Michigan Motorsports brackets are built for serious performance builds. Instead of settling for restrictive factory placements, these brackets allow you to shift your D514A coils 1-3/8" down toward the center of the valve cover, providing much-needed clearance and a cleaner engine bay aesthetic. They are specifically designed for 514A and D510C coils on GM LS Series engines, though you should keep in mind they aren't compatible with LSA or LS9 valve covers. The kit arrives ready to install with both brackets and all necessary mounting hardware included. It is refreshing to find American-made components that offer such a precise, natural aluminum finish for high-end engine tuning.

Most builders assume that standard babbitt is enough, but the real secret to surviving high-RPM or boost-heavy LS builds lies in the secondary lubrication layer. The Dura-Bond CH-10T set changes the game for 1997-2003 1st Gen engines by integrating a PTFE Teflon coating directly onto high-performance bimetal bearings. These aren't your typical shells. They feature a seamless steel tube construction that eliminates the surface interruptions that often lead to installation breakage. Because they use a lead-based babbitt, you get superior embeddability and anti-seizure properties that harder materials simply can't match. With a centerless ground design that maintains incredibly tight wall tolerances, these bearings offer the precision needed to prevent catastrophic oil starvation during extreme engine loads.
