Notes: DUE TO A LACK OF SUSPENSION TRAVEL OF THE SHOCK ABSORBERS, WE CAN NOT MANUFACTURE A LOWERED NOR A RAISED HEIGHT FOR THIS VEHICLE
Kings Springs exclusively use high quality, high stress X5K spring steel.
This new generation steel allows King Springs to further improve many of their existing designs by reducing the amount of steel required in a spring, making it substantially lighter (by approximately 30%) and reducing the solid height therefore increasing travel. Being of particular benefit at all top levels of Motorsport, this new high stress material was introduced to the leading v8 super car teams (inc DJR/TP, FTR & NISSAN) in early 2007 giving a hugely successful endorsement of its characteristics & proven durability.
Although considerably expensive, King Springs have introduced this new high stress steel to their passenger car and 4wd designs which benefit the most at no extra cost to the consumer. As of now all King Springs manufactured coils are now in X5K material.
Many of our springs are designed to cross reference and give various height options on some vehicles. This information is too diversified and complicated to be printed and is often conditional. Please consult our technical staff if specialist height options are requested.
VEHICLE RIDE HEIGHTS (centre hub to guard)
An extensive library of vehicle ride heights is being compiled and this information is available to all customers.
Please note: The following height classifications are a generalization only. Degree of lowering can vary between part numbers and vehicles. Spring design i.e. spring rate and vehicle height is relative to market demand. If exacting measurements are required for vehicle ride heights please contact King Springs.
Front Low: Lowers vehicle approximately 30mm below standard.
Front STD: Standard Height.
Front Raised: Raises vehicle approximately 20mm above standard (recommended for bull bar, country driving or whenever increased ground clearance is desired).
Rear Low: Lowers vehicle approximately 30mm below standard.
Rear STD +:Standard height to 20mm raised.
Rear Raised: Raises vehicle approximately 30-40mm above standard (recommended for excessive towing, load-carrying or LPG tank etc)
NOTE: Super Low coils are generally 40-50 below standard.
4WD & Ford "F" Series Coils
Front and Rear STD: Raises vehicle approximately 10mm-20mm above standard.
Front and Rear RAISED: Raises vehicle approximately 30mm-40mm above standard.
Note: All heights mentioned are a generalisation only. Vehicle ride heights can vary, depending on:
Life and/or age of vehicle
Accessories fitted to the vehicle
Factory options (Country Pack, S Pack etc.)
When discussion vehicle ride heights, consider all of the above and advise customers accordingly.
LPG - For cars fitted with LPG tanks use part No. in Raised column to sit Std. Height.
Measuring Coil Springs
Listed below is relevant information required when identifying or measuring coil springs.
Free Length: The length of the coil at it's longest point out of the vehicle not under load. To measure, lay coil flat, butt one end to flat surface at right-angles with coil.
Open Strut Length/Trapped Length: The length of the coil when vehicle body is jacked up and all load is removed from spring (except pre-load).
Static Length: The length of the coil in the vehicle as it stands under normal load.
Inside Diameter: The width of the spring at it's widest point from inside edge to inside edge.
Note: Check both ends, as many coils can reduce at one end only or be conical in design.
Total Coils: The total number of complete turns from start to finish (including reductions if any).
Material Diameter: (Check with verniers) Note: Check end coils as diameter may decrease.
End Configuration: There are several types of end finishes:
i. Normal: (not ground, straight cut) Note: Measure end gap at tip to next coil (FWO-)or (FWC-)
ii. Ground: Ground flat (TWC-)
iii. Pigs Tail: End reduces greatly and will fit inside the coil below (PT-)
iv. Reduced: End coil will sit on top of coil below. (RED-)
Trouble Shooting (Coil and Leaf Springs)
Kings Performance Replacement Coil Springs in both STD and Raised Heights are often shorter than the springs they are replacing. This is because they don't compress as far under the initial pre-load or weight on the vehicle.
When sorting vehicle height problems, be sure that all wheel and tyre sizes and type pressures are compatible. Measure all four corners. Measure centre hub to guard, with vehicle on flat surface.
NOTE: Most vehicles transfer weight diagonally.
Many Part numbers listed in the catalogue have a driver's side and passenger side and are marked accordingly.
Wheel alignment is recommended after having front springs fitted on all vehicles. Some vehicles require wheel alignment on rear when rear springs are fitted. Refer wheel alignment specialist.
Allow 4WD Leaf Springs settling time of approximately 500klms then check and re-tighten all U-bolts and Shackles.
Custom-designed coil springs can be made to order in most cases within 10-12 working days.
