Selecting the correct spring rate is critical for optimal ride quality and suspension performance. When ordering, choose your spring rate based on constant accessory load only — this means permanently fitted equipment such as bullbars, winches, roof racks with accessories, drawer systems, canopies, steel trays, and dual battery systems. Front constant loads typically include bullbars (30-70kg), winches (30-50kg), upgraded bumpers, and heavy-duty bash plates. Rear constant loads include canopies (80-150kg), steel trays (100-200kg), drawer systems (50-100kg), dual spare wheel carriers, long-range fuel tanks, and permanently mounted water tanks. Do not factor in occasional loads such as camping gear, passengers, firewood, or trailer tongue weight when selecting spring rates — these are temporary loads. Selecting springs that are too heavy for your actual constant load will result in a harsh, uncomfortable ride and may cause premature wear to other suspension components including bushings and shock mounts.
Professional installation by a qualified 4WD suspension specialist is strongly recommended for this comprehensive lift kit due to the requirement for spring compressor tools, torque specifications, and precise suspension geometry setup. A full four-wheel alignment is mandatory after installation to reset caster, camber, and toe angles — the included upgraded control arms provide 3 degrees of caster correction to restore factory steering feel and stability. Allow a 500km break-in period for springs to settle and shock absorbers to bed-in before making final ride height measurements or damping adjustments. During the break-in period, you may notice the vehicle sitting slightly higher than final settled height — this is normal as coil springs compress and seat into their mounting points.
Dobinsons Spring & Suspensions has been engineering and manufacturing premium 4WD suspension systems since 1953, with over 70 years of Australian outback testing and continuous product development. Every Dobinsons kit is designed and validated across Australia's harshest terrain including corrugated outback tracks, coastal sand, rocky high country, and heavy-duty commercial applications. Trusted by serious tourers, commercial operators, and tradespeople nationwide, Dobinsons suspension delivers proven reliability backed by comprehensive warranty coverage and Australia-wide dealer support. Explore the complete Dobinsons suspension range for complementary steering dampers, swaybar links, and suspension components.
This kit is ideal for Dodge Ram 1500 owners who demand professional-grade suspension performance for heavy towing (caravans, camper trailers, boats), extended remote-area touring with significant accessory loads, or commercial applications requiring reliable load-carrying capacity and durability. Trade professionals carrying tools, equipment, and materials will appreciate the adjustable damping and load-rated springs that maintain ride quality under varying load conditions. If you frequently exceed 400kg rear payload or tow near maximum capacity, consider pairing this kit with airbag suspension for additional load support and on-the-fly ride height adjustment.

This kit is specifically engineered for the Dodge Ram 1500 DS series manufactured between 2018 and 2020 with the 5.7L V8 HEMI engine. It is not compatible with earlier Ram models or the DT series (2021+) which have different suspension geometry and mounting points. The kit includes vehicle-specific control arms, shock absorber lengths, and spring rates designed exclusively for the DS platform. If you're unsure about your vehicle's series designation or have a different model year, please contact our suspension specialists who can verify fitment and recommend the correct kit for your specific Ram variant.
This Dobinsons kit delivers 75mm (approximately 3 inches) of front lift and 50mm (approximately 2 inches) of rear lift, measured at the vehicle's chassis after spring settlement and with appropriate constant accessory loads fitted. The slightly lower rear lift maintains a level or slightly nose-down stance which is ideal for towing heavy trailers and caravans. Final settled height will vary by 10-20mm depending on your selected spring rate and fitted accessory weight including bullbars, winches, canopies, and drawer systems. Allow 500km of driving for springs to fully settle and compress to their final operating height before making final measurements or assessments.
This comprehensive kit includes everything needed for a complete front and rear suspension upgrade: 2 x IMS adjustable monotube front shock absorbers, 2 x heavy-duty front coil springs, 2 x long travel upper control arms with 3-degree caster correction, 2 x IMS monotube rear shock absorbers, 2 x heavy-duty rear coil springs, plus all necessary mounting hardware and bushings. The control arms are essential for maintaining proper suspension geometry after the lift and preventing accelerated tyre wear. You will need to specify your preferred spring rates for both front and rear based on your constant accessory loads during the ordering process to ensure optimal ride quality and load-carrying performance.
Yes, this Dobinsons kit is specifically engineered to enhance towing stability and load-carrying capability for the Ram 1500 platform. The IMS monotube shock absorbers feature advanced valving that controls body roll and rear squat under heavy tongue loads, while the load-rated coil springs maintain ride height when towing within the vehicle's rated capacity. The adjustable front shocks allow you to increase compression damping when loaded or towing for improved control and reduced pitch. For Ram owners who frequently tow heavy caravans exceeding 2,500kg or carry maximum rear payload, we recommend considering supplementary airbag suspension for additional load support and the ability to level the vehicle under varying load conditions.
Yes, upgraded control arms are essential and included in this kit. The Dobinsons long travel upper control arms provide 3 degrees of caster correction which is critical after installing a 75mm front lift to restore proper steering geometry. Without caster correction, you would experience vague steering feel, poor high-speed stability, wandering on the highway, and accelerated inner tyre edge wear. These control arms also increase suspension travel compared to factory arms, improving wheel articulation and off-road traction. The control arms feature heavy-duty construction with quality bushings designed to handle the increased loads and articulation demands of lifted suspension and off-road use.
A professional four-wheel alignment is absolutely mandatory after installing this lift kit and should be performed by a qualified suspension shop or alignment specialist familiar with lifted 4WD vehicles. The alignment must reset caster, camber, and toe angles across all four wheels to ensure proper tyre wear, steering response, and vehicle stability. The included caster-correcting control arms will restore most of the front caster angle, but fine adjustments are still required for optimal geometry. Driving the vehicle without proper alignment after a lift kit installation will result in rapid and uneven tyre wear, poor handling characteristics, and potential safety issues at highway speeds.
Yes, Dobinsons manufactures these coil springs in multiple spring rates to accommodate different constant accessory loads, and you must select your appropriate rates for both front and rear when ordering. Choose your spring rate based only on permanently fitted accessories such as bullbars, winches, canopies, steel trays, drawer systems, and roof racks — not occasional loads like camping gear, passengers, or firewood. During checkout, you'll be prompted to specify your current constant load category for accurate spring selection. Selecting springs that are too soft will cause excessive sag and bottoming, while springs that are too heavy will result in a harsh, uncomfortable ride and potential damage to shock mounts and bushings over time.
With this 75mm front and 50mm rear lift installed, most Dodge Ram 1500 DS models can accommodate up to 35-inch diameter tyres depending on wheel offset, backspacing, and specific tyre tread width. Tyre fitment also depends on whether you're running factory wheels or aftermarket wheels with different offset specifications. Some minor trimming of plastic inner guards or mud flaps may be required for full steering lock clearance with 35-inch tyres, particularly with aggressive tread patterns. For the most accurate tyre fitment advice specific to your wheel and offset combination, we recommend consulting with a professional suspension installer or 4WD fitment specialist who can assess clearances at full compression and steering lock before purchasing tyres.
All Dobinsons suspension components in this kit are covered by the manufacturer's comprehensive warranty against defects in materials and workmanship. Shock absorbers and coil springs are typically covered for 3 years or 100,000km (whichever occurs first) under normal operating conditions, while control arms and bushings carry similar coverage periods. Warranty coverage requires professional installation with correct torque specifications, mandatory wheel alignment, and use within the manufacturer's specified load ratings. To validate warranty claims, retain your purchase receipt and installation documentation. For specific warranty terms, conditions, and claim procedures, please refer to the Dobinsons warranty information included with your kit or contact our customer service team for detailed coverage information.
Absolutely — this Dobinsons IMS kit is engineered to deliver excellent daily driving comfort while dramatically improving off-road capability and load-carrying performance. The monotube shock absorber design with adjustable damping allows you to tune the suspension for comfortable highway cruising when unloaded, then firm up the damping when carrying heavy loads or towing. The kit maintains composed high-speed handling, reduced body roll compared to factory suspension, and quiet operation without harshness over typical road imperfections. Many Ram 1500 owners report improved ride quality compared to worn factory suspension, particularly when springs are correctly matched to their constant accessory loads. The robust construction ensures long-term reliability for both daily commuting and weekend touring adventures across any terrain.
Perfect for Family Touring and Beach Runs
Finally got the Dobinsons lift kit fitted to our Ram and the difference is night and day. Took the family down to the Coorong last month and the ride quality on corrugations was so much better than the factory setup, plus we've got the clearance now for beach driving without worry. Installation was straightforward and the monotube shocks handle the weight of our camper trailer beautifully. Couldn't be happier with how it's transformed our weekend adventures.(5)
Perfect Setup for Work and Weekend Trips
Been running this Dobinsons lift kit on my Ram for about six months now, using it daily for work and the occasional beach or desert run on weekends. The ride quality is honestly better than stock - doesn't feel harsh loaded up with tools and materials during the week. Really impressed with how well the monotube shocks handle both highway driving and the rough stuff without any drama.(5)
Perfect Upgrade for Our Family Adventures
Finally got the Dobinsons lift kit fitted to our Ram 1500 and couldn't be happier with how it's transformed the ride. We've done two camping trips since installation, including some pretty rough tracks up in the High Country, and the difference in handling corrugations is night and day. The kids even commented on how much smoother the drive was, which says something! Well worth every cent for anyone doing regular touring.(5)
