The Easiest Suspension to Install and Maintain

Ridewell's 240 series trailer air-rides remain unmatched in the industry for ease of maintenance. The patented features are engineered to reduce the labor and costs associated with installation, alignment and re-bushing. Only from Ridewell will you receive all the benefits of these premium features at standard prices.

Exceptional ride quality

Engineered with a longer hanger than used by other makers, the 240's maintain a horizontal type geometry between the single pivot bushing and the axle center. This geometry eliminates the longitudinal jerks on the trailer that are transferred to the tractors fifth wheel, improving the efficiency of both driver and vehicle. Ridewell's design geometry reduces the over-extension of shock absorbers and air springs so that their full service life is attained. While performing as a pivot for extreme axle articulation, the 240's single, massive bushing also acts as a load cushioning element in addition to the air spring.

Benefits

Your drivers will experience more comfort, your cargo will receive maximum care, and your fleets will run more profitably when equipped with 240 trailer air suspensions. Patented, contoured axle seat optimizes axle weldment by decreasing stress concentrations, no u-bolts required. Longwearing, double-bonded pivot bushing can be installed or replaced with common shop tools, no hydraulic presses required. Clamp for pivot bushing is lock-bolted with the Huckbolt fastening system for consistent, reliable clamp-up. Proven, reliable eccentric bolt at left and right-hand pivots allows simple axle alignment by installer and end-user. Pre-mounted shock absorbers and pre-drilled height control valve bracketry insure precise installation and proper shock and air spring tolerances.

Configuration

The Ridewell model RAR-240 suspennsion is designed to accommodate a range of ride heights for each specific model and can be used on a variety of axle types for various applications. The following characteristics are commonly referenced for set-up of the suspension:

1. Ride Height (also called Mounting Height) - The distance from the bottom of the trailer frame to the centerline of the axle. Ride height is related to frame height (the distance from the bottom of the frame to the ground) by the following formula:

   Ride Height = Frame Height - Loaded Tire Radius

2. Beam Centers - The centerline-to-centerline distance from one axle seat to the other. For the RAR-240, this is also the same as the centerline-to-centerline distance from one hanger to the other. The RAR-240 is designed to fit up onto standard I-beam trailer frames at beam centers that correspond to standard axle track widths as shown below with standard wheel-end equipment. Installation at wider beam centers will reduce suspension clearances; installation at narrower beam centers will de-rate the axle beam capacity per the axle manufacturer's specifications. For non-standard beam centers, frames, frame centers, axle track or wheel-end equipment, the installer is responsible for verifying clearances, axle capacity, proper fit-up, and any addtional required support structure.
