Why you should use Formula 4x4 Leaf Springs

Better Ride Plus Carrying Ability

Original manufacturers generally run soft first stage springs and stiffer second stage, resulting in a ‘kick’ or jolt to the driver when driving with little or no load. Formula work with a firmer and higher rate single stage or first stage spring, giving a smoother and safer ride when carrying weight.

Better Shackle Angle

The most critical function of a leaf spring is to achieve better ride handling through correcting the shackle angle. When raising a vehicle, the spring Camber changes along with the main leaf angle. When at an incorrect angle, the shackle will cause many negative effects on your vehicle, resulting in poor handling. To achieve a superior spring, Formula have incorporated lengthened spring main leaves where possible. This creates an ideal shackle angle in a lifted vehicle.

Better Design

Formula pay attention to accuracy of spring eyes to ensure the SuperPro bushings fit correctly and locate the spring for smooth rotation. Redesigned wrap leaf shapes are used for great security, such as a military wrap.

Reduction of Stiction

To deliver the reduction of stiction in a leaf spring, Formula have incorporated features such as shot peening of the main leaf, graphite grease, anti-friction leaf slipper pads, diamond cut ends, and tapered ends. These features are incorporated depending on the vehicle application and its use.

Noise Reduction

It is critical that the alignment of leaf springs is correct in order to reduce the noise and friction of a vehicle. Formula also adds additional clips and clamps to maintain this and ensure the reliability and durability of the vehicle.

3 Year or 100,000km Warranty

We offer a three year product warrantty on all our shock absorbers, no exceptions. Ensuring you are covered when you come into a problem. We want you to be able to drive in comfort without any worries.
