PMR 4-Link Housing Brackets w/Doublers

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

Dial in your launch, traction, and consistency with PMR’s 4‑Link Housing Brackets and Doublers — engineered for builders who demand repeatable geometry and race‑proven strength. Every part is waterjet‑cut, giving you perfectly clean edges with no heat distortion, no hardened edges, and no micro‑cracks — just precise, consistent edges.

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 requiring precise adjustability.

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

• Extreme-duty construction: The brackets are made from 1/4-inch thick chromoly steel and doublers crafted from 1/8-inch thick chromoly steel, built to handle 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 all 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.
