    The AccuAir VU4 4-Corner Valve Unit is engineered to provide the cleanest installation and most reliable operation on the market. This electronic solenoid valve unit can inflate or deflates up to 4 individual Air Springs and has built-in push-to-connect 3/8” D.O.T. approved air fittings for all of its plumbing connections. The robust internal solenoid valve architecture maximizes flow rates, provides bubble-tight sealing, and guarantees operation up to 200 psi for millions of cycles. All of this technology is housed in a unique enclosure design which routes each of the solenoid wires to a single weatherproof connector, eliminating typically loose wires. This not only improves the appearance, but it also guarantees proper operation for every installation. With an overall compact size of only 5.28"x 2.75"x 2.75" and the ability to survive harsh under vehicle environments, this product is ideal for any application with Air Suspension.

    • 3/8" Press-fit D.O.T. fittings eliminate pipe threads for leak free operation
    • 5.28" length

    For its accuracy, reliability, and ease-of-use, this AccuAir e-level controller with touchpad has become an industry favorite. This e-level controller offers the ability to program and save 3 different riding heights. This is possible due to the TruPosition technology that saves your positions by the touch of a button and will maintain vehicle height while parked or driving. No matter the road conditions or the number of passengers your vehicle height will remain the same. This automatic intelligence won't be noticed by the drive and is sure to improve the ride quality and handling characteristic for any vehicle with Air Suspension. Each system calibrates to the vehicle upon installation and then learns how your Air Suspension behaves over time. This flexibility allows the e-Level controller to be used on any vehicle and requires no user tuning.

    • 3 programmable heights
    • Adjusts as needed while driving or while in park
    • Vehicle height stays constant no matter road conditions or passenger number
    • Touchpad included

    These nylon bushings for 4-bar ends are perfect for your custom build. Bushing fits rod ends with a 1.125" I.D. and rod end width of 1.485". The steel sleeve I.D. is 0.625", O.D. is 0.815" and the length of the sleeve is 1.76". Kit includes a set of 8 bushings with 8 sleeves.

    Note: These bushings are not a replacement for Speedway 4-bar rod ends as they are wider.

You will need to trim 0.435" off the overall width to match the 1.050" width of the bushing that came with the Speedway rod end.
