Rear 4-Link HD Öhlins Suspension – Ford Mustang 1964.5–1968

The 1960s Mustangs are true legends, but their original suspension systems were never designed to meet today’s driving and performance standards. Leaf springs worked well in their time, but with more powerful engines, aggressive driving, and modern expectations, they quickly prove insufficient. The solution is the modern 4-Link HD Öhlins rear suspension from Restomotive.

A New Foundation for Power and Stability

The core of the kit is a 9-inch rear axle with a custom housing, capable of handling torque loads of up to 1000 Nm without issue. The entire setup is mounted in a tubular subframe connected to the body at four points. This design eliminates flex and maintains stable geometry even under the most demanding conditions.

Control Arms and Adjustability

The system uses two types of control arms: trailing and diagonal. Both are made from S355 structural steel, and with the use of turnbuckles, their geometry can be precisely adjusted. Spherical bearings (uniballs) replace rubber bushings, eliminating play and significantly improving suspension precision — crucial for dynamic driving and cornering.

Öhlins STX Dampers

At the heart of the kit are Öhlins STX dampers, equipped with threaded adjustability and damping control. They allow fine-tuning of suspension characteristics to suit driving style, track conditions, or driver preferences.

The lower damper mounts are CNC-machined and fitted with bushings, providing additional ride height adjustment options and enhanced durability.
