Rear End Mounting Kit

The Chassis Engineering Inc AS-1018CG is a comprehensive leaf spring rear end mounting kit specifically engineered for 1937-1939 Chevrolet vehicles equipped with gas shocks. This bolt-on kit is designed to fit a wide range of rear ends, accommodating axle housing diameters up to 3 inches, with a recommended overall width of approximately 58 inches. It is crucial to specify the exact rear end you will be using when placing your order to ensure proper fitment. This complete kit includes all necessary components for a robust suspension setup: front and rear spring mounts, an upper shock bar, and lower shock plates that can be mounted with the angle facing up or down to achieve optimal clearance and a perfect fit. It also comes with gas shocks, shackles, U-bolts, spring pads, and 2-1/2 inch wide rear slider springs. All hardware and instructions are conveniently shipped in three separate boxes. Installation involves removing the original rear end, springs, and shocks, then carefully positioning and bolting the new components to the frame. The process requires precise alignment, especially noting that Chevrolet did not always maintain consistent mounting hole patterns across these model years. Installation instructions detail how to center the rear end within the fender opening, drill holes, and secure all mounts and components. It is important to ensure the car bottoms out on a rebound rubber, not the shocks, to prevent damage. New springs may settle up to an inch within the first 500 miles of use, and their initial arch can vary, which is considered normal operation. The kit utilizes rubber bushings for springs to absorb vibrations and road noise, providing an ideal combination of comfort and performance.
