Air Lift 3P Air Management Systems

Air Lift engineers asked themselves: what would the ultimate air suspension be like? How would it combine an easy-to-use, reliable, and feature-rich system with powerful technology and beautiful design? Air Lift Performance 3P air management system is the result of three years of development and testing. It is the most advanced product Air Lift has ever created. The 3P combines pressure-based control with the ability to add ride-height sensing technology with the upgrade to height sensors. While both types of air management have been utilized before, this is the first product to harness the benefits of both systems—instantly improving suspension control, performance, and vehicle ride flexibility. (See notes on Model 27780 below) Kits include: * 3H/3P digital controller * Integrated ECU + manifold * Advanced electrical wiring harness * 60 ft. of 1/4 in. air line * Inline water filter * All wiring, fuses, hardware, etc. required for installation Model 27780 has additional features: In an effort to make the 3P air management systems more customizable to builders across the globe, Air Lift has introduced a threaded-port manifold. With the option of threaded FNPT ports, builders can create trunk-setups so stunning that they rival their vehicles' stance. This manifold allows builders to choose the fitting and air line option that best fits their needs and aesthetic. The threaded ports on the new manifold make integrating straight or elbow hard lines and/or threaded-steel braided air lines easier and safer, with less chance of damage to the internal O-rings. The threaded-port manifold is built with the same advanced technology as the push-to-connect 3H and 3P systems—high-grade, fully integrated components, a 32-bit processor for precise 4-corner control, built-in Bluetooth, and an intelligent accelerometer for accurate adjustments. With limitless mounting options and a simple, single harness connection, the manifold can be easily installed to the builder's exact specifications.

RideTech MOMENTUM Chassis Kits

Ridetech, a leader in air and coil-over suspension systems for more than 30 years, proudly announces the launch of its MOMENTUM chassis kits. This all-new platform gives classic muscle car enthusiasts a clean-slate foundation for their next project—delivering modern handling, increased performance, and design flexibility beyond the limits of factory frames. Builders can now enjoy the benefits of a fully engineered chassis while tailoring the suspension to their preferred style of driving, whether that's comfortable street cruising, high-performance autocross, or full track use. Key engineering highlights include: * RideTech's MOMENTUM Chassis Series is a new platform for classic muscle cars, offering modern handling, optimized suspension, and modular options, initially for 1968-1972 models * Optimized suspension geometry—the chassis re-engineers pickup points to improve camber gain, caster, roll center, and Ackermann steering geometry * Enhanced stability—the chassis is significantly stiffer than a stock frame, which reduces flex and increases structural rigidity for more predictable handling * Improved cornering—a new integrated sway bar helps reduce body roll and improve balance, leading to sharper cornering and greater stability * Confidence-inspiring control—the design provides improved handling for both daily driving and more demanding situations like autocross or track events * Increased tire and wheel clearance—the chassis is engineered to accommodate larger, modern wheel and tire sizes that would not fit on a factory chassis * More aggressive fitment—allows for wider tires (e.g., up to 275mm front and 295mm rear) with room for larger fitments, especially when combined with mini tubs in the rear * Adjustable ride height—the system allows for roughly a 2-inch drop from stock but can be adjusted to the desired ride height * Kit offers modular suspension options that allow for air or coilover setups * Chassis is compatible with existing Ridetech A-body suspension components * Engine and transmission flexibility provides provisions for various motor mount plates (small block Chevy, Olds, Pontiac, Buick, GMLS, or Gen 5 LT) and features an adjustable crossmember that adapts to popular automatic and manual transmissions

Borgeson Pitman Shaft Seals

Borgeson Saginaw Vega 140 pitman shaft seals deliver factory-specification sealing performance designed specifically for Saginaw Vega 140 Series manual steering gears. These OE replacements provide critical sealing at the point where the pitman shaft exits the steering box housing to connect with the pitman arm—preventing gear oil leakage while keeping dirt and moisture from contaminating the internal steering gear components. The seals support proper lubrication levels within the Vega 140 steering box, which is essential for smooth manual steering operation and long component life in these compact steering gears that were commonly used in smaller GM vehicles. Their leak-prevention capability enables restoration builders and mechanics to eliminate oil seepage around the pitman shaft area that commonly develops as original seals deteriorate over time, particularly in vintage applications where these seals have been in service for decades.
