Selecting the correct spring rate is critical for optimal performance, ride comfort and component longevity. You must calculate your constant load - the combined weight of permanently fitted accessories that remain on the vehicle at all times. Common rear accessories affecting spring selection include aluminium or steel trays, canopies, toolboxes, drawer systems, dual battery setups, water tanks, long-range fuel tanks, and rear bar/tow package combinations. Occasional loads such as cargo, passengers, camping gear and trailer towing should NOT be included in spring rate selection - these variable loads are managed by correct shock absorber specification or supplementary airbag suspension systems. Over-rating your springs by selecting rates for occasional rather than constant loads results in harsh ride quality, reduced traction, premature wear on bushings and joints, and compromised handling characteristics.
Professional installation by a qualified suspension specialist or experienced automotive technician is strongly recommended for coil spring replacement. Installation requires spring compressors, correct lifting equipment, torque specifications and understanding of suspension geometry and safety procedures. A full four-wheel alignment is mandatory after installation to ensure correct ride height, camber, caster and toe settings - failure to align after spring replacement can result in premature tyre wear and compromised handling. Allow 500 kilometres of varied driving for springs to settle and suspension bushings to seat before final ride height and handling assessment. For optimal performance on lifted or heavily loaded Ram 1500 applications, consider pairing these rear springs with upgraded control arms to correct suspension geometry and maintain wheel alignment settings.

These Tough Dog rear coil springs are engineered specifically for Dodge Ram 1500 models from 2009-2018 (DS/DJ/D2 series) and RAM 1500 Classic models from 2019-current, covering both 3.6L V6 and 5.7L HEMI V8 engines. They're designed as direct bolt-in replacements for factory rear coil springs with no modifications required. To confirm exact fitment for your specific model year and variant, check our online parts finder or contact our team with your VIN number. Different spring rates are available to suit various constant load configurations, so correct rate selection is essential for optimal performance.
Spring rate selection must be based solely on your constant load - the combined weight of permanently installed accessories that remain on the vehicle at all times. For rear springs, calculate the weight of your canopy or tray, toolboxes, drawer systems, dual battery setup, water tanks, long-range fuel tank, and rear bar with tow package. Do NOT include occasional loads such as cargo, passengers, camping equipment or trailer tongue weight in your calculation, as these variable loads should be managed through correct shock absorber specification or supplementary airbag systems. Selecting spring rates that are too heavy for your actual constant load will result in harsh ride quality, reduced traction and premature suspension component wear.
This kit includes a pair (2 springs) of Tough Dog heavy duty rear coil springs manufactured from premium grade spring steel with corrosion-resistant powder coat finish. The springs come with fitment hardware where applicable and installation specifications. This kit includes rear springs only - front coil springs, shock absorbers, upper control arms, and other suspension components are sold separately and must be ordered individually. For complete suspension upgrades, we recommend pairing these springs with quality matched shock absorbers and considering control arm upgrades for lifted or heavily loaded applications.
Yes, when correctly specified, these Tough Dog coil springs provide excellent support for towing applications by maintaining proper rear ride height and suspension geometry under load. However, the spring rate should be selected based on your constant accessory load only, not towing weight. Variable towing loads are best managed with quality matched shock absorbers that provide appropriate damping control, or by adding adjustable airbag suspension which allows you to increase rear support when hitching up and return to comfortable unladen ride when not towing. This approach delivers optimal performance both loaded and unloaded without compromising daily driving comfort.
Control arm upgrades are not mandatory for spring replacement at factory ride height, but they become increasingly important as lift height increases or when correcting suspension geometry on heavily loaded vehicles. If your Ram 1500 experiences significant rear squat under constant load, the increased spring rate will restore ride height but may affect suspension geometry, particularly camber and toe settings. Upgraded adjustable control arms allow your suspension specialist to properly dial in alignment settings and maintain optimal tyre contact patch throughout the suspension's travel range. This is especially beneficial for vehicles used in demanding off-road, touring or heavy towing applications where suspension articulation and wheel alignment are critical.
Yes, a full four-wheel alignment is absolutely mandatory after replacing coil springs on your Ram 1500. Even when installing springs of similar rate to factory specifications, the change in ride height and settling characteristics will alter your suspension geometry and affect camber, caster and toe angles. Driving without proper alignment after spring replacement will cause rapid and uneven tyre wear, compromised handling characteristics, and reduced stability during braking and cornering. Your alignment technician should perform the alignment after initial installation, then you should return for a re-check after 500 kilometres of varied driving once the springs have fully settled and bushings have seated.
Yes, front and rear spring rates should absolutely be specified independently based on the constant load distribution across your Ram 1500. Most Ram 1500 owners carry more permanent weight in the rear (canopies, toolboxes, drawer systems) than the front (bull bars, winches, driving lights), so it's common and correct to specify heavier rear spring rates than front rates. The goal is to achieve level ride height and balanced handling characteristics when carrying your typical constant load. Never match spring rates front-to-rear arbitrarily - each end of the vehicle must be rated according to its actual constant accessory weight for optimal ride quality, handling and component longevity.
These rear coil springs are designed primarily to restore or maintain proper ride height when carrying constant accessory loads rather than provide significant lift for larger tyre fitment. While correctly specified springs will prevent rear squat and may provide modest height improvement over sagging factory springs, tyre clearance is determined by multiple factors including ride height, wheel offset, suspension travel, and clearance to body panels and suspension components. For Ram 1500 applications requiring significant lift for larger tyres, a complete matched lift kit with front and rear springs, extended shocks, and appropriate suspension geometry correction components is recommended. Contact our team to discuss your specific tyre size goals and receive appropriate suspension recommendations.
Tough Dog rear coil springs are backed by comprehensive manufacturer warranty coverage against defects in materials and workmanship when installed by a qualified technician and used within their designed specifications. Warranty coverage requires retention of proof of purchase, professional installation with documentation, and adherence to recommended spring rate selection guidelines based on actual constant load. Warranty does not cover springs damaged by incorrect rate selection, overloading beyond rated capacity, installation errors, or modifications to the vehicle that alter suspension geometry or load distribution. For specific warranty terms, duration and claim procedures, refer to the documentation included with your springs or contact our customer service team.
Absolutely - when correctly specified for your constant load, these Tough Dog coil springs deliver excellent daily driving comfort, highway stability and ride quality while providing the load support needed for your permanent accessories. The key to comfortable daily driving is honest assessment of your constant load and selecting spring rates that match your actual permanent accessory weight, not anticipated occasional loads. Over-rating your springs by selecting rates for worst-case towing or maximum payload scenarios will result in harsh ride quality when unladen and compromise daily driving comfort. Paired with quality matched shock absorbers, correctly specified Tough Dog springs provide the perfect balance of load support and ride comfort for Ram 1500 owners who use their vehicles as daily drivers, work trucks and touring vehicles.
