Dobinsons IMS 50mm Lift Kit for Dodge Ram 1500 DS (2018-2021) — Adjustable Monotube Suspension

This complete system provides approximately 50mm (2 inches) of lift height over factory ride height when using the correctly specified spring rates for your vehicle's constant accessory load. Actual lift height can vary by 10-15mm depending on spring rate selection, installed accessory weight, and whether your vehicle's factory suspension has sagged over time. The lift is achieved through raised coil springs at both front and rear, maintaining balanced geometry and proper suspension travel. This 50mm lift height is ideal for fitting 33-inch tyres (depending on wheel offset) while preserving on-road ride comfort and handling characteristics suitable for daily driving and highway touring.

This complete lift kit includes two Dobinsons IMS adjustable front monotube shock absorbers, two front coil springs with selectable spring rates, two Dobinsons long travel upper control arms with 3-degree caster correction, two IMS adjustable rear monotube shock absorbers, and two rear coil springs with selectable spring rates. All necessary mounting hardware, brackets, and detailed installation instructions are provided. You'll need to select your preferred spring rates for front and rear during the ordering process based on your vehicle's constant accessory load. This is a comprehensive kit designed to replace your factory suspension components — no additional shocks, springs, or control arms are required for installation.

Yes, this Dobinsons IMS kit is excellent for towing applications thanks to the adjustable monotube shock absorbers that allow you to increase compression damping when hitched to caravans, camper trailers, or boat trailers. The adjustable damping helps control rear-end squat, maintains level ride height under tongue weight, and improves braking stability when towing heavy loads. When selecting your rear spring rate, base your choice on constant accessories only — not towing loads — as the shock adjustment handles the additional towing weight. For the ultimate towing setup, many Ram owners pair this lift kit with supplementary airbag suspension for infinitely adjustable load support and the ability to level the vehicle regardless of trailer tongue weight.

Yes, and upper control arms are included in this complete kit — you don't need to purchase them separately. The Dobinsons long travel upper control arms feature integrated 3-degree caster correction, which is essential when lifting the Ram 1500's independent front suspension. Without caster correction, lifted Ram trucks commonly experience steering wander, poor steering return to center, accelerated inner tyre wear, and unstable highway handling. These engineered control arms restore proper steering geometry, maintain factory-like steering feel, and ensure even tyre wear patterns. The long travel design also increases suspension articulation for improved off-road wheel travel and obstacle climbing capability compared to factory arms.

Yes, a full four-wheel alignment is absolutely mandatory after installing any suspension lift kit, and the Dobinsons system is no exception. The alignment must be performed by a workshop with appropriate Ram 1500 specifications and experience with lifted independent front suspension systems. The technician will set correct caster (aided by the 3-degree correction in the upper control arms), camber, toe angles, and thrust angle to ensure proper steering feel, even tyre wear, and stable highway tracking. Don't skip this critical step — improper alignment after a lift will result in premature tyre wear costing hundreds of dollars, poor handling characteristics, and potentially unsafe steering behavior. Budget $180-$250 for a quality four-wheel alignment when planning your installation costs.

Yes, this kit features selectable spring rates for both front and rear coil springs, allowing you to precisely match the springs to your vehicle's constant accessory load. During the ordering process, you'll select spring rates based on the combined weight of permanently installed accessories such as bull bars, winches, canopies, drawer systems, roof racks, long range tanks, and upgraded bumpers. It's critical that you select spring rates based only on constant loads — do not include occasional loads like camping gear, passengers, or towing weight in your calculation. Selecting springs that are too heavy will result in a harsh ride, reduced articulation, and potential damage to suspension mounting points. If you're unsure about the correct spring rate, our suspension experts can guide you through the calculation process based on your specific accessory list.

The 50mm lift provided by this kit typically allows fitment of 33-inch diameter tyres on the Dodge Ram 1500 DS without rubbing under most driving conditions, though the exact size depends on your wheel offset, tyre width, and suspension articulation during off-road use. With standard offset wheels, you can generally fit tyres up to 285/70R17 or 275/65R18 (both approximately 33 inches tall) without trimming or modifications. Wider tyres or more aggressive offsets may require minor trimming of plastic fender liners during full suspension compression or steering lock. If you're planning 35-inch tyres, you'll likely need additional lift beyond this 50mm kit, along with potential body modifications. For specific tyre and wheel combination advice for your Ram 1500, contact our fitment specialists who can provide guidance based on your exact wheel specifications.

Dobinsons provides comprehensive manufacturer warranty coverage on all components in this kit, with warranty periods varying by component type — shock absorbers and control arms typically carry extended warranty protection reflecting their engineered durability and quality construction. Warranty coverage protects against manufacturing defects in materials and workmanship under normal use conditions, though specific warranty terms, duration, and claim procedures should be confirmed at the time of purchase. To maintain warranty validity, professional installation is recommended, and you should retain proof of purchase and installation records. Warranty does not typically cover wear items, damage from accidents or misuse, or components that have been modified. For detailed warranty information specific to this kit, contact our team before purchase or review the warranty documentation included with your shipment.

Absolutely — the Dobinsons IMS system is engineered to deliver excellent on-road comfort and handling characteristics while providing genuine off-road capability when needed. The monotube IMS shock technology with adjustable damping allows you to dial in ride comfort for daily commuting, then increase damping for off-road adventures or towing on weekends. Many Ram 1500 owners use this kit on vehicles that serve as primary family transport, work trucks, and touring vehicles, reporting improved ride quality over worn factory suspension even when unladen. The 50mm lift height is moderate enough to maintain reasonable step-in height, center of gravity, and highway stability compared to more extreme lift kits. The key to excellent on-road manners is selecting the correct spring rates for your actual constant load — overly heavy springs will compromise ride comfort significantly, so be honest about your accessory weight when ordering.
