Ridetech 55-57 Chevy (Two Piece Frame) Bolt-On 4-Link Double Adjustable - 11037197

The Ridetech 55-57 Chevy (Two Piece Frame) Bolt-On 4-Link Double Adjustable (11037197) is a direct bolt-on rear suspension system engineered specifically for 1955-1957 Chevy Bel Air, One-Fifty, and Two-Ten models built on the two-piece (35-1/8" wide) frame. Designed to replace the factory leaf spring rear suspension, this kit dramatically improves ride quality, handling, and traction while allowing you to dial in an adjustable, lowered stance without cutting the floor pan or welding to the frame.

Key Features & Benefits

• Double Adjustable Bars: Adjust lower bar length by simply loosening the jam nuts and turning — no need to remove bar-end hardware, making ride height and pinion angle fine-tuning fast and repeatable.
• Patented R-Joint Rod Ends: Combine low-friction movement, lateral stability, full-range articulation, and quiet operation for street or track-worthy performance.
• Eliminates Spring Wrap & Wheel Hop: The 4-link geometry positions the rear axle more precisely, improving stability through corners with optimized roll center and anti-squat characteristics.
• Bolt-On Installation: A stout tubular crossmember bolts between the frame rails; only two brackets are welded to the axle housing, so there's no cutting through your Tri-Five's floor pan.
• Maximum Tire Clearance: Bars run to the inside of the frame rails, keeping clearance open for wider rear tires and a lower stance.
• Durable Finish: Coated in a satin black powder coat for long-term corrosion resistance and a clean, finished look under the car.

Fitment

This kit is built for the following 1955-1957 Chevrolet applications with the two-piece frame:

• 1955-1957 Bel Air (Base)
• 1955-1956 Bel Air Beauville
• 1955-1957 Bel Air Nomad
• 1955-1957 One-Fifty Series (Base)
• 1955-1957 Two-Ten Series (Base)
• 1955-1957 Two-Ten Series Del Ray

Note: this double-adjustable version is not compatible with Wagon models using the stock fuel tank. Since the '55-'57 Tri-Five was produced with two distinct frame widths, verify whether your frame has a weld seam along the bottom rail (two-piece, 35-1/8") before ordering — a separate part number is used for the one-piece (33-11/16") frame.

Frequently Asked Questions

Does this kit include shocks or coil-overs?
No. This 4-link system is designed for use with Shockwaves or coil-overs, which are sold separately.

Will this fit any 1955-1957 Chevy?
It's designed specifically for the two-piece frame (35-1/8" wide) found on certain Bel Air, One-Fifty, and Two-Ten models. A different part number is needed for the one-piece frame (33-11/16" wide), so confirm your frame type first.

Do I need to cut or weld my car to install this?
No floor pan cutting or frame welding is required — the crossmember bolts in, and only two brackets are welded to the rear axle housing.

Can I use this on a Nomad wagon?
The double-adjustable version is not compatible with Wagon models retaining the stock fuel tank.
