Toughdog Front Coil Springs for Toyota LandCruiser 105 Series — 2-6 Inch Lift

These Toughdog coil springs provide between 2 and 6 inches of front lift depending on your constant accessory load (CAL). A lightly equipped 105 Series with minimal accessories will achieve close to 6 inches of lift, while vehicles fitted with heavy bull bars, winches, long-range tanks, and other front-end accessories will settle closer to 2-3 inches. The progressive spring rate design means the springs compress proportionally to the weight applied, which is why final ride height varies based on your specific setup. To achieve balanced suspension geometry, you'll typically want similar lift heights front and rear, so factor in your accessory weight when planning your complete suspension upgrade.

This kit includes a pair (2 pieces) of Toughdog heavy-duty front coil springs with progressive rate design and corrosion-resistant powder coat finish. The springs are sold as a front axle pair only and do not include shock absorbers, spring isolators, bump stops, or mounting hardware — you'll reuse your existing isolators and components or purchase new ones separately if required. These are coil springs only, not a complete lift kit, so you'll need to source shock absorbers separately if yours require replacement. For a complete suspension upgrade solution, consider pairing these springs with matched Toughdog shocks and any necessary suspension components for optimal performance and ride quality.

Yes, these Toughdog coil springs are excellent for towing applications with the LandCruiser 105 Series, particularly when towing caravans, camper trailers, or heavy work trailers. The progressive spring rate provides the additional load support needed to maintain safe ride height and handling characteristics when the front axle carries the weight of tow ball download plus front-end accessories. However, remember these are front springs only — for optimal towing performance you should also upgrade your rear suspension with appropriate heavy-duty springs or coils matched to your typical towing weight. Many LandCruiser towers also benefit from adding airbag suspension at the rear for fine-tuning load support and maintaining level ride height regardless of trailer weight variations.

While not strictly mandatory for a 2-inch lift, upgrading to adjustable or extended control arms is highly recommended when achieving 3 inches or more of front lift on your LandCruiser 105 Series. Lifting the front suspension changes the castor angle, which can result in vague steering feel, reduced on-road stability, and accelerated ball joint wear. Upgraded control arms allow you to correct the castor angle back to optimal specifications, dramatically improving steering response, high-speed stability, and overall handling both on-highway and off-road. Most experienced 4WD suspension specialists will recommend control arm upgrades as part of any moderate to significant lift kit installation to maximize safety, performance, and component longevity.

Yes, a complete four-wheel alignment is absolutely mandatory after installing these lift springs on your LandCruiser 105 Series. Changing front ride height alters all suspension geometry angles including castor, camber, and toe settings, which directly affects steering feel, tyre wear patterns, and vehicle handling characteristics. A professional alignment ensures your suspension geometry is set to manufacturer specifications (or corrected with adjustable components) for optimal safety and performance. Skipping the alignment will likely result in premature and uneven tyre wear, wandering steering, and potentially unsafe handling dynamics. Budget for alignment costs when planning your suspension upgrade — it's not optional, it's an essential part of the installation process.

These particular Toughdog coil springs come in a progressive rate design that automatically adjusts to load, which means they provide appropriate spring rate across a wide range of weights from unladen to fully loaded. Unlike linear-rate springs that require you to specify exact constant load ratings, the progressive design handles variable loads more effectively by compressing more easily under light loads (comfortable empty ride) and progressively stiffening as weight increases (controlled loaded ride). This makes them ideal for LandCruiser owners whose accessory loads vary, such as removing camping gear between trips. If you have very specific constant heavy loads or specialized requirements, contact our team to discuss whether custom spring rates or alternative Toughdog spring options might better suit your particular application and usage pattern.

With 2-6 inches of front lift from these Toughdog coil springs (matched with appropriate rear lift), most LandCruiser 105 Series owners can comfortably fit 33-inch tyres (285/75R16 or similar) with minimal to no trimming required, depending on wheel offset and specific tyre profile. Some owners successfully run 35-inch tyres with additional modifications including diff drop brackets, body mount chop, and potentially minor guard trimming. Tyre clearance also depends significantly on wheel backspacing, shock absorber placement, and full suspension compression under articulation. Remember that larger tyres affect gearing ratios, speedometer accuracy, braking performance, and steering effort — many owners install diff gear ratio changes when moving to 35-inch rubber. For specific tyre fitment advice based on your planned lift height and wheel choice, consult with experienced 105 Series specialists.

Toughdog coil springs are backed by the manufacturer's comprehensive warranty covering defects in materials and workmanship under normal use conditions. Specific warranty duration and terms are provided with your purchase and typically cover manufacturing defects but not wear and tear from normal operation or damage from accident, misuse, or incorrect installation. To maintain warranty validity, springs must be installed by qualified technicians following Toughdog's installation guidelines, and the vehicle should not exceed GVM (Gross Vehicle Mass) ratings. Always retain your proof of purchase and installation documentation. For complete warranty terms, conditions, and claim procedures, contact us directly or refer to the warranty documentation included with your Toughdog components at time of delivery.

Absolutely — these Toughdog coil springs are engineered to provide excellent ride quality for daily driving, highway touring, and commuting while also delivering the durability and load capacity needed for off-road adventures and heavy work use. The progressive spring rate design ensures the springs aren't overly stiff when unladen, providing comfortable on-road manners for everyday driving around town or long highway trips. When loaded with camping gear or towing, the springs progressively stiffen to maintain control and prevent excessive body roll or suspension compression. Thousands of Australian LandCruiser owners run Toughdog suspension as their daily driver setup precisely because it offers the best balance of comfort, capability, and durability without the harsh ride often associated with heavy-duty 4WD springs. Pair them with quality matched shock absorbers for optimal all-round performance.
