Selecting the correct spring rate is critical for optimal performance and ride quality. Your spring rate should be chosen based on constant load only — this means accessories and equipment that remain on your vehicle permanently, not occasional loads like camping gear or towing. Common constant rear loads include: steel tray conversions, alloy trays, tool boxes, drawer systems, dual battery setups, long-range fuel tanks, rear bars with tyre carriers, and permanent canopy or tub installations. Occasional loads such as camping equipment, payload in the tray, and towing should NOT be factored into spring rate selection as this will result in an unnecessarily stiff ride when unladen and may cause premature wear to suspension components. Calculate the total weight of your permanent accessories and select the spring rate that matches this constant load for optimal comfort and performance.
Professional installation by a qualified mechanic or 4WD suspension specialist is strongly recommended for rear coil spring replacement. Installation requires appropriate spring compressors, lifting equipment, and safety procedures to prevent injury. A full four-wheel alignment is mandatory after installation to ensure correct suspension geometry and prevent premature tyre wear. Allow approximately 500km of varied driving for springs to settle and reach their final operating height — slight initial sag is normal during this bedding-in period. For vehicles with significant lift or those running heavier loads, consider upgrading to heavy-duty shock absorbers for improved control and damping performance.
Toughdog has earned its reputation as Australia's number one suspension brand through decades of proven performance in the harshest conditions. Every component is engineered and tested specifically for Australian vehicles, roads, and operating environments — from outback corrugations to coastal corrosion.

These Toughdog rear coil springs are ideal for Dodge Ram 2500 owners who've added permanent accessories and need to restore factory ride height, tradespeople running constant tool and equipment loads, caravan towers experiencing rear-end sag, and anyone seeking improved load-carrying capability without compromising unladen ride quality. If you frequently change your payload or towing loads, consider supplementing these springs with adjustable airbag suspension for on-demand load leveling and enhanced versatility — the perfect combination for maximum flexibility.
All Toughdog coil springs are Australian stock with fast dispatch nationwide and backed by expert technical support.

These Toughdog rear coil springs are specifically engineered for Dodge Ram 2500 DJ II models from 2020 onwards. They're designed as direct replacements using factory mounting points and hardware for precise fitment. The springs fit both standard and heavy-duty rear axle configurations. If you have a pre-2020 model or different Ram variant, these springs will not be suitable. Always verify your vehicle's series designation (DJ II) and model year before ordering to ensure correct fitment.
These are load-rated replacement springs designed primarily to restore factory ride height under load rather than provide additional lift. The actual ride height achieved depends on the spring rate selected and your vehicle's constant accessory load. Unladen, springs may sit slightly higher than factory until they settle during the 500km break-in period. Under your selected constant load, springs will return the vehicle to approximately factory ride height with improved load-carrying capacity. These are not lift springs — if you're seeking additional ground clearance, contact our team to discuss complete lift kit options.
This kit includes a pair (2) of Toughdog heavy-duty rear coil springs specifically engineered for the Dodge Ram 2500 DJ II 2020+. The springs feature high-tensile steel construction with corrosion-resistant powder coating and are manufactured to Australian Design Rules compliance. Installation hardware is not included as the Ram 2500 uses its original factory mounting hardware and isolators. Professional installation is recommended, and you'll need to arrange wheel alignment separately after installation. All springs are load-tested and come with Toughdog's manufacturer warranty.
Yes, these Toughdog coil springs are excellent for towing applications when correctly rated for your constant load. They reduce rear-end sag, improve towing stability, and maintain better suspension geometry under load compared to worn factory springs. However, towing loads should NOT be factored into your spring rate selection — choose springs based only on permanent accessories. For variable towing loads or maximum versatility, consider supplementing these springs with airbag suspension which allows you to adjust support based on actual load. This combination provides optimal performance whether towing heavy or running unladen.
While not strictly mandatory, upgrading to heavy-duty shock absorbers is highly recommended when fitting new coil springs, especially if your existing shocks have done significant kilometers. New springs with worn shocks will compromise ride quality, handling, and braking performance. Matched Toughdog shocks are engineered to work with these springs for optimal damping characteristics. If your Ram carries heavy loads, tows regularly, or sees rough road conditions, quality shocks will dramatically improve control, comfort, and safety. Our suspension experts can recommend matched shock absorber options for your specific application.
Yes, a full four-wheel alignment is absolutely mandatory after installing new rear coil springs on your Ram 2500. Changing spring height alters suspension geometry including camber, caster, and toe angles which directly affects tyre wear, handling, and safety. Even if ride height appears similar to before, suspension angles will have changed. Professional alignment should be performed after installation and again after the 500km settling period for optimal results. Skipping alignment will result in premature and uneven tyre wear, poor handling characteristics, and potentially unsafe driving dynamics.
Select spring rate based exclusively on your constant accessory load — permanent equipment that stays on your vehicle all the time. Calculate the total weight of items like steel trays, tool boxes, drawer systems, dual batteries, long-range tanks, rear bars, and tyre carriers. During checkout, select the load rating that matches this constant weight. Do NOT include occasional loads like camping gear, payload in the tray, or towing weight — these are temporary loads. Selecting too heavy a spring rate for your actual constant load will result in harsh ride quality and potential damage to suspension components. Contact our team if you need help calculating your constant load.
These springs are designed to restore factory ride height under load rather than provide significant lift for larger tyres. Tyre clearance depends on many factors including wheel offset, tyre width, suspension articulation, and existing modifications. If your goal is fitting significantly larger tyres, you'll likely need a complete lift kit with increased ride height, modified suspension geometry, and potentially body modifications. These replacement springs will improve load handling and restore sagged ride height but won't provide the clearance needed for substantial tyre size increases. Contact our team to discuss complete lift solutions if larger tyres are your primary objective.
These Toughdog coil springs are covered by Toughdog's comprehensive manufacturer warranty against defects in materials and workmanship. Warranty coverage applies when springs are correctly selected for the vehicle's constant load, professionally installed, and used within their designed load capacity. The warranty does not cover damage from overloading, incorrect spring rate selection, improper installation, or modification. Keep your proof of purchase and installation records for warranty claims. As an authorized Toughdog dealer, we'll assist with any warranty issues should they arise. Contact our team for specific warranty terms and conditions.
Absolutely — these Toughdog coil springs are engineered to provide excellent ride quality for daily driving, highway touring, and urban use when correctly rated for your constant load. They maintain comfortable characteristics unladen while providing firm support under load, making them ideal for dual-purpose vehicles used for both daily commuting and weekend work or touring. The progressive spring rate design ensures comfortable initial travel with increased support as load increases. Unlike budget springs that are either too soft or too harsh, Toughdog springs deliver the refined balance between comfort and capability that makes them suitable for all driving conditions from city streets to remote touring.
