Apache Springs – Premium Performance & 4WD Coil Springs

Engineered for Strength. Designed for Performance. Trusted by Enthusiasts.

Apache Springs are built using high quality, high stress X5K spring steel, offering industry leading strength, reduced weight, and enhanced suspension performance. This next generation spring technology allows Apache Springs to manufacture lighter, stronger springs up to 30% lighter than conventional designs while increasing travel and reducing solid height.

Originally developed and tested in elite motorsport environments, including top V8 Supercar teams, this high-stress material has proven its durability, responsiveness, and reliability under the harshest conditions. Today, that same elite grade performance is available for your passenger your Ram 1500 DS, at no additional cost.

Ride Height Options – Tailored to Your Needs

Apache Springs offer a variety of ride height options, depending on your vehicle and usage:

Car Coil Springs:

• Front Low: ~30mm lower than standard

• Front Standard: OE height

• Front Raised: ~20mm higher than standard (ideal for bull bars, rough roads)

• Rear Low: ~30mm lower than standard

• Rear STD+: Standard to ~20mm raised

• Rear Raised: ~30–40mm raised (great for towing, heavy loads, LPG tanks)

• Super Low: ~40–50mm lower than standard

4WD & Ford F-Series Coil Springs:

• STD Height: ~10–20mm above factory height

• Raised Height: ~30–40mm above factory height

Note: Actual height change depends on the vehicle’s age, condition, accessories, and factory trim options.

How to Measure Coil Springs:

When identifying or replacing coil springs, the following specs are useful:

• Free Length – Overall length out of the vehicle (no load)

• Open Strut / Trapped Length – Coil length with suspension fully extended

• Static Length – Coil length under normal load

• Inside Diameter – Measure both ends (some may be tapered or conical)

• Total Coils – Number of full turns, including any taper

• Material Diameter – Measured with vernier calipers (some ends may vary)

• End Configurations:

  • Normal Cut (FWO-/FWC-)

  • Ground Flat (TWC-)

  • Pigtail (PT-)

  • Reduced Diameter (RED-)

Fitment, Troubleshooting & Alignment

• Apache performance springs may appear shorter than OE, but they compress less under preload—resulting in correct ride height.

• Always measure vehicle ride height hub-to-guard with the vehicle on a level surface.

• Consider accessory weight, tyre/wheel sizes, and factory suspension packages when selecting spring height.

• Most coil springs are side-specific—always match the part number to driver or passenger side.

• Wheel alignment is required after fitting front springs—and on some vehicles, rear as well.

For vehicles with LPG tanks, select the “Raised” variant to maintain standard ride height.

NOTICE OF DISCLAIMER–Lift and Levelling Kits

Not all lift kits are legal to install on your vehicle. It is the customers’ responsibility to check regulations pertaining to their vehicle and warranty coverage, prior to purchasing and the installation of all lift and levelling kits.

Lift and levelling kits may interfere with vehicle functions including but not limited to stability control, auto levelling functions and chassis clearance issues.

The bigger the lift or levelling kit that is fitted increases the chances of the factory CV joints and ball joints wearing out prematurely. High articulation CV joints are available to minimize this issue if required.

In certain circumstances the factory inner CV joint boots may slip off the end of the shaft due to the change in the angle after a front lift has been fitted. In most circumstances fitting an improved CV boot clamp to the CV boot will assist with this matter.

Ball joints on the upper control arms need to be lubricated after installation and re-greased at each service interval. Without adequate grease they will wear out prematurely and will need to be replaced. It is the customers responsibility to ensure that the ball joints are always kept greased.

It is paramount that all lift kit components that have been installed, be re-torqued after the first 100 kms to adjust for any settling of the suspension components; then rechecked at each service interval to ensure that everything is correctly torqued. This is the customers responsibility as loose components can cause damage to your vehicle.

It is suggested that the customer does their own research prior to purchasing and requesting the installation of lift and levelling kits to their vehicle.
