Chromoly 4-Link Chassis Bracket w/Doublers

Precision Geometry Backed by 50+ Years of Rear‑Suspension Tuning

Dial in your launch, traction, and consistency with PMR’s Chromoly 4‑Link Chassis Brackets with Doublers — built for fabricators who demand repeatable geometry and race‑proven strength. Each bracket is precision‑waterjet‑cut for perfectly clean edges and zero heat distortion. Unlike laser‑cut parts that can harden, micro‑crack, and fail under load, PMR’s process preserves full material integrity for dependable performance run after run.

With over 50 years of hands‑on rear‑suspension tuning, PMR brings real track data and real fabrication experience into every part we build. These brackets aren’t generic laser-cut plates — they’re the result of decades spent optimizing instant center, anti‑squat, and bar angles for drag cars that leave hard and stay planted.

Key Features

• Race‑Proven Geometry: Designed around the most effective 4‑link layout for drag racing, street/strip, and chassis builds requiring precise adjustability.

• Multiple Bar Positions: Wide range of hole spacing for fine‑tuning, anti‑squat percentage, and hit characteristics.

• Heavy‑Duty Construction: The brackets are crafted from 1/4-inch thick chromoly steel, while the doublers use 1/8-inch chromoly, built for extreme-horsepower applications.

• Fabricator‑Friendly: Clean edges, consistent dimensions, and bracket symmetry make setup and welding straightforward.

• PMR Quality: Developed using the same standards we apply to our NHRA‑certified chassis components.

Why Builders Choose PMR

Because we’ve spent half a century tuning rear suspensions, we know what actually works on the track — not just on paper. These brackets give you the adjustability and durability needed to get the car out of the hole clean, predictable, and fast.
