ULTIMATE 9-INCH FORD REAR
MARK WILLIAMS ENTERPRISES
Mark Williams Enterprises in Louisville, Colorado, offers its "Ultimate" 9-in. Ford rearend assembly that is manufactured from an aerospace alloy aluminum, which company sources report is 30% more durable than the commonly used 6061 aluminum.
Performing all CNC machining in-house, the modular design incorporates a selection of end bells that determine the housing's width. For both four-link and solid installations, mounts are available with either flanged or full-floater axels. In addition to the mounts, steel tubes are available for street applications.
M-W's "Ultimate Hi-Torque" axles are made of 300M material and are backed by a 10-year warranty against breakage. Finishing the "Ultimate" assembly are special 10-in. pitch diameter ring and pinion gears, made in collaboration with Gleason Corp. Designed for high-horsepower applications, these are made from 9310 alloy, precision ground, shot-peened, REM micro-polished and sub-zero treated.

EXTREME PRESSURE GREASE
HOT SHOT'S SECRET
Hot Shot's Secret in Mt. Gilead, Ohio, now offers two new multi-purpose extreme pressure organoclay-based greases: 7460EP and 7150EP. This uniquely compounded solubilized molybdenum (moly) provides a bleed-resistant grease that's infused with rust and corrosion inhibitors with antioxidant additives that provide a higher level of tackiness for longer-lasting performance.
The 7150EP is ideal for high-speed automotive applications in parts such as wheel bearings that need to withstand the dynamic forces of thrust, radial loads and overall smooth and enduring operation. The 7460EP is ideal for press section bearings, machine bearings or any machine bearings that require a more viscous, robust grease that can withstand extreme pressures and heavier loads. Hot Shot's Secret's 7000 series EP grease was engineered to deliver performance in demanding conditions and can tolerate extreme heat, cold, or moisture.

FITECH–ONE GAUGE LCD KIT
FITECH FUEL INJECTION
Available in 7- or 10-inch sizes, the FiTech-One Gauge LCD touchscreens from FiTech Fuel Injection in Riverside, California, were designed to seamlessly integrate with FiTech EFI systems. FiTech's customizable touchscreen allows users to design personalized screen layouts to create a display that fits their unique setup. These new displays deliver a highly accurate, low latency, adaptable interface that can accommodate a wide range of sensors to ensure user-friendly flexibility for all types of enthusiasts.
The One Gauge LCD kit can monitor critical engine and vehicle parameters, including rpm, engine load, MAP, coolant temps, oxygen sensor AFR, and much more. The CNC-machined, black anodized aluminum housing offers splash-proof protection with rear flush mounting patterns and flexible wiring options. This highly modular display kit allows for expandability so users can easily add features like lap timing, shift lights and datalogs. The GPS speedometer will also include compass direction, altitude, and location data without requiring any physical connections.

IMCA MODIFIED SPEC RACING ENGINE
SPEEDWAY MOTORS
The New IMCA Modified spec racing engine (#12135503) from Speedway Motors Racing Engines, located in Lincoln, Nebraska, produces more power and torque than a 604-crate engine while maintaining drivability. In addition to the impressive power and torque ratings, the new IMCA Modified spec engine is an unsealed crate motor that utilizes low-maintenance hydraulic roller cams—providing racers the freedom to maintain their engine throughout a race season. Each engine uses a 3.480-in. stroke stock-appearing steel crankshaft, IMCA-approved SCAT Pro-Series connecting rods, and forged flat-top pistons yielding the required 9.0:1 compression ratio.
Each engine is topped with an MSD Pro Billet distributor and the IMCA Modified spec required Edelbrock 2975 Victor Jr. single plane intake manifold. The displacement is 355–360 cubic inches, paired with Dart IMCA-approved cast iron cylinder heads and a steel 7-quart oil pan with IMCA-required 1-in. inspection plug. Lastly, each engine is broken in on a dyno with a proprietary program and tuned for the use of methanol fuel only, producing a solid race engine that promotes power and reliability.

PPE CRANKCASE VENTILATION OIL/WATER SEPARATION KIT
PACIFIC PERFORMANCE ENGINEERING
Pacific Performance Engineering (PPE) in North Las Vegas, Nevada, launches its new PPE crankcase ventilation oil/water separation Kit for 2020–2025 GM 3.0L DURAMAX. PPE, concerned with optimizing engine efficiency and longevity, tackled the oil and hydrocarbon emissions that are vented through the crankcase ventilation system, and redirected into the turbo compressor housing. Contaminants tend to mix with EGR gases, leading to harmful buildup in vital components like the intake manifold, swirl valves, and intake valves. The Crankcase Ventilation Oil/Water Separation Kit aims to combat reduced performance, poor fuel economy, elevated EGTs, compression loss, increased emissions, and the impact of potential damages seen on other vital engine components found in extended periods of contamination accumulation.
The high-quality PCV hoses are oil-resistant, reduce mixture velocity, enhance condensation of oil, hydrocarbons and water vapor. Through a stainless-steel mesh screen, the advance filtration system effectively captures the oil, hydrocarbons, and water vapor, preventing these contaminants from re-entering the system. The aluminum oil reservoir is engineered to fit securely above the fender liner and has an easily accessible drain hose for user convenience.
