Selecting the correct spring rate is critical for achieving optimal ride quality, load capacity and component longevity. Your spring rate choice should be based on the constant accessory load carried in your Landcruiser 300 Series — not occasional loads or towing weight. Constant rear accessories include dual battery systems, drawer systems, rear canopy or hardtop weight, second fuel tank, rear bar and wheel carrier, fridge slide, water tanks, permanent camping gear, and roof rack/roof top tent weight transferred to rear suspension. Occasional loads like eskies, camping gear for weekend trips, or towing a trailer should not be factored into your spring rate selection as this will result in an overly stiff ride when unladen. If you regularly carry heavy loads but want flexibility for unladen driving, consider pairing your chosen spring rate with airbag suspension for adjustable load support.
Professional installation by a qualified 4WD suspension specialist is strongly recommended for rear coil spring replacement on the Landcruiser 300 Series. Installation requires specialised spring compressor equipment, safe lifting and support procedures, and proper torque specifications for suspension mounting bolts. A full four-wheel alignment is mandatory after installation to ensure correct axle geometry, prevent premature tyre wear, and maintain factory handling characteristics. All Dobinsons coil springs require a 500km break-in period during which the springs will settle 5-10mm from initial installed height — avoid overloading during this period and have ride height checked after settling is complete. For optimal performance and geometry correction, consider pairing these rear springs with upgraded control arms when running 30mm or higher lift heights.
Dobinsons has been engineering and manufacturing premium 4WD suspension components for over 60 years, with Australian-designed springs and shocks proven across millions of kilometres on outback tracks, corrugated desert roads, beach sand and alpine terrain. Every Dobinsons spring is tested to destruction in laboratory conditions then validated through real-world Australian expedition testing before release. Trusted by touring enthusiasts, tradespeople, emergency services and mining operations across Australia, Dobinsons delivers the quality, reliability and warranty support that serious 4WD owners demand.

These rear coil springs are ideal for Landcruiser 300 Series owners who have added aftermarket accessories and need to restore correct ride height and load capacity, touring enthusiasts building a long-range tourer with rear drawer systems and dual batteries, tradies carrying constant tool and equipment loads, and families towing caravans or camper trailers who need rear squat control and stability. The 10mm option suits lightly accessorised vehicles wanting improved spring rate without significant lift, while the three 30mm options cater to progressively heavier build specifications. For owners who vary between unladen daily driving and heavy loaded trips, combining the appropriate constant-load spring with supplementary airbag suspension provides the ultimate flexibility in load management.

Yes, these Dobinsons rear coil springs are specifically engineered for all Toyota Landcruiser 300 Series variants from 2021 onwards. They are a direct replacement for the factory rear coil springs and fit both petrol and diesel engine variants including GX, GXL, VX and Sahara models. The springs are designed to work with the factory rear suspension configuration and do not require any suspension geometry modifications. If you have any concerns about fitment for your specific build date or variant, our technical team can verify compatibility using your VIN number.
This kit offers two lift height options depending on which spring variant you select. The C59-817V option provides 10mm of lift above standard height, ideal for restoring ride height on accessorised vehicles or running slightly larger tyres. The C59-819V, C59-821V and C59-823V options all provide 30mm of lift above standard height, allowing clearance for larger tyres and improved ground clearance for off-road touring. Note that all springs will settle approximately 5-10mm during the first 500km break-in period, so initial installed height will be slightly higher than final settled height.
This kit includes a pair (2 pieces) of Dobinsons variable rate rear coil springs specifically calibrated for the Landcruiser 300 Series. You select one of four spring rate options at purchase based on your constant accessory load requirements. The kit does not include shock absorbers, spring seats, rubber isolators, U-bolts or other mounting hardware — these components can be reused from your factory setup if in good condition or purchased separately if replacement is needed. Pairing these springs with Dobinsons IMS or MRA shock absorbers is recommended for a matched suspension system.
Yes, these springs are excellent for towing applications when the correct load rating is selected. The higher load-rated options (C59-821V for 100-200kg and C59-823V for 280-400kg) significantly reduce rear squat when towing caravans, camper trailers or boats, maintaining proper suspension geometry and headlight aim under load. However, remember that towing weight itself should not be factored into spring rate selection — choose your spring rate based on constant accessory weight carried in the vehicle. For ultimate towing flexibility, many owners pair appropriately-rated springs with supplementary airbag suspension to fine-tune load support for varying tow weights.
Control arm upgrade is not mandatory for the 10mm lift option as suspension geometry changes are minimal. For the 30mm lift options, while factory control arms will continue to function, upgrading to adjustable or extended-length aftermarket control arms is recommended for optimal suspension geometry, improved articulation and corrected castor angle. Upgraded control arms allow your suspension specialist to properly dial in alignment after lift installation, reducing tyre wear and improving highway handling. The investment in quality control arms becomes increasingly worthwhile if you're running the 30mm lift with larger tyres and planning regular off-road touring.
Yes, a full four-wheel alignment is absolutely mandatory after installing these rear coil springs on your Landcruiser 300 Series. While rear coil replacement primarily affects ride height rather than steering geometry, the change in suspension position alters load distribution and can affect overall vehicle geometry including thrust angle. Professional alignment ensures your vehicle tracks straight, prevents premature and uneven tyre wear, and maintains factory handling characteristics. The alignment should be performed after the initial 500km break-in period when the springs have fully settled to their final ride height for most accurate geometry adjustment.
You must select one spring rate option when ordering — this kit contains a pair of matched springs at your chosen rate. The four available options are: C59-817V (10mm lift, minimal load), C59-819V (30mm lift, 0-50kg constant load), C59-821V (30mm lift, 100-200kg constant load), or C59-823V (30mm lift, 280-400kg constant load). Choose the spring rate that matches your typical constant accessory load — the total weight of permanently installed rear accessories like drawer systems, dual batteries, rear bars, canopies and roof racks. If your load varies significantly between daily driving and touring, consider supplementary airbag suspension rather than oversizing your spring rate, as excessively stiff springs will provide harsh ride quality when unladen.
The 10mm lift option provides minimal additional tyre clearance and is primarily designed to restore factory ride height on accessorised vehicles — it may allow 10-15mm larger diameter tyres without other modifications. The 30mm lift options provide significantly more clearance and typically allow 32-33 inch tyres on factory wheels with minimal or no body modifications, though exact fitment depends on tyre width, wheel offset and whether diff drops or other geometry corrections are installed. For aggressive tyre sizes or wide offset wheels, additional modifications including body trimming, wheel arch flares or suspension geometry correction may be required. Always test-fit your desired tyre size through full steering and suspension articulation before committing to a purchase.
Dobinsons rear coil springs for the Landcruiser 300 Series are backed by a comprehensive manufacturer warranty against defects in materials and workmanship. The specific warranty period and terms are provided with your purchase and cover spring failure, breakage or loss of rate under normal operating conditions. Warranty does not cover damage from accidents, incorrect installation, overloading beyond the selected spring's rated capacity, or modification of the springs. To maintain warranty validity, springs must be installed by a qualified technician, used within their specified load rating, and not subjected to excessive heat or corrosive chemicals. Retain your proof of purchase and installation documentation for any warranty claims.
Absolutely — when the correct spring rate is selected for your constant load, these Dobinsons variable rate springs deliver excellent daily driving comfort. The variable rate design provides soft initial compression for comfortable unladen cruising on highways and city streets, then progressively firms up under load for control and stability. Many Landcruiser 300 Series owners run these springs as their everyday suspension setup, enjoying restored ride height, improved load capacity and enhanced handling compared to sagging factory springs. The key to comfortable daily driving is honest spring rate selection based on actual constant accessories — oversizing spring rate for occasional loads or towing will result in harsh ride quality when the vehicle is empty.
