ISUZU D-MAX KITS
The Pedders Suspension Lift Kit makes the workhorse Isuzu D-Max into a more refined passenger vehicle
Enhanced ride quality in both unladen and laden conditions.
The increased articulation and ride height of 35mm to 40mm enables the Isuzu D-Max to have the ability to cover very rough ground, as well as enhancing the entry and exit angle of undulating terrain.

PEDDERS PRODUCT FEATURES
The primary function of springs, whether they be Leaf, Coil or Torsion Bars, is to absorb the shocks that are created when driving across irregular road surfaces and to maintain the tyres’ contact with the road.
The spring rate, or stiffness, must be matched to the weight of the vehicle resting on it and the weight of the other suspension components and the wheel. Spring rate also controls roll stiffness, or body roll. By reducing the amount of body roll, we reduce the amount of wheel camber change. Large camber change can drastically reduce the tyre’s contact with the road surface, severely limiting the handling potentially during cornering.
The handling of most vehicles is substantially improved by increasing the original spring rate to an optimum rate which maximises tyre adhesion and reduces body roll for better handling. Increasing the spring rate beyond the optimum rate distracts from the handling potential as the tyres begin to skip over bumps, reducing grip and safety.
Coil springs are the foundations of the modern suspension system with most car manufacturers preferring Coil Springs due to their advantages of weight, tenability, space and ease of manufacture. Pedders research, design and manufacture their own range of Coil Springs from their own World-Class Manufacturing plant in Victoria, Australia to QS9001 standards.
Coil Spring Design and manufacturing is a craft which requires strict adherence to a demanding series of procedures, all of which are critical to the performance of the final product. Pedders undertakes the following key steps in relation to its Coil Spring Manufacturing Process:
- Hot Coiling
- Oil Quenching
- Furnace Tempering
- Shot Peening
- Loaded Height and Rate Testing
- Powder Coating and Packaging
- Pedders produces its coil springs to the highest possible standards following QS9001 requirements. Pedders offer the highest possible quality coil springs due mainly to the following quality manufacturing elements;
- Shot Peening – This, using a full hardened steel shot, is the process used to relieve stresses on the wire that are wound into the spring during coiling. Shot peening provides extra life to the spring which improves performance, durability and longevity.
Scragging – Scragging is the process of compressing the spring beyond its normal working limit which effectively pre-sets the spring and determines its finished height. Pedders scrag to 100% or ‘coil bound’ to improve the long term durability and performance of the spring.
- Load Testing – To ensure the most accurate finished product for the desired application, Pedders Suspension load tests 100% of its coil springs to the vehicle’s installed height specification. This system involves loading a spring with a pre-determined, application specific load and specifying the height that the spring must come to. This is a far more accurate and complex system than simply a measure of ‘free’ or ‘unloaded’ height. Pedders define a height tolerance of +/- 2mm for its range of Sports Ryder Springs and +/- 5mm for its range of Touring Springs. This height tolerance for Pedders Touring Springs is consistent with that of original equipment springs. Pedders also load test 100% of its springs rather then simply batch testing.
