Selecting the correct spring rate is critical for optimal performance and ride quality. Choose your spring rate based on your vehicle's constant load — this means the weight of accessories and equipment permanently installed on your vehicle, not occasional loads or towing weight. Common constant load items for the LandCruiser 105 Series rear include: dual battery systems, long-range fuel tanks, rear drawers and storage systems, dual spare wheels, rear bar and tire carrier, water tanks, roof racks with permanent loads, fridge slide systems, and camping equipment storage. Occasional loads such as passengers, camping gear loaded for trips, and towing caravans or trailers should NOT be included in your spring rate calculation. Selecting an unnecessarily heavy spring rate will result in a harsh, uncomfortable ride and may cause premature wear to other suspension components including shock absorbers and bushings.
Professional installation by a qualified mechanic or experienced 4WD workshop is strongly recommended for coil spring replacement due to the high tension loads involved and requirement for spring compressors and specialized tools. A complete wheel alignment is mandatory after installation to ensure correct steering geometry, prevent uneven tire wear, and maintain safe handling characteristics. Allow a 500-kilometer break-in period for springs to settle and reach their final ride height — slight settling is normal during this period. For vehicles with significant lift or heavy constant loads, consider pairing these rear springs with matching front springs and upgraded premium shock absorbers for balanced performance, or explore our complete lift kits for comprehensive suspension solutions.

Yes, these Toughdog rear coil springs (SKU 9711) are specifically engineered for Toyota LandCruiser 105 Series models produced from 1998 to 2007. They are designed as direct replacement rear springs using factory mounting points with no modifications required. These springs fit all 105 Series variants including base, GXL, and Sahara models with standard coil spring rear suspension. If you have aftermarket suspension components already fitted or are unsure about compatibility with your specific build, please contact our team to confirm fitment before ordering.
These Toughdog rear coil springs provide between 2 to 6 inches (approximately 50-150mm) of rear lift depending on your vehicle's constant load weight and the spring rate you select. A lightly loaded 105 Series with minimal accessories will achieve closer to 6 inches of lift, while a heavily loaded tourer with dual batteries, drawers, spare wheels, and rear bar will sit lower at around 2-3 inches of lift. The actual lift height is determined by the balance between spring rate strength and your vehicle's permanent accessory weight. Most typical touring setups achieve 3-4 inches of rear lift with correctly matched spring rates.
This kit includes a pair (2 pieces) of Toughdog heavy-duty rear coil springs specifically designed for the Toyota LandCruiser 105 Series. The springs feature progressive rate design, premium alloy steel construction, and corrosion-resistant powder coat finish. This is a springs-only package — it does not include shock absorbers, spring compressors, installation hardware, bushings, or other suspension components. Front coil springs are sold separately if you're building a complete lift kit. Professional installation is recommended as spring compressors and specialized tools are required for safe installation.
Yes, these Toughdog rear coil springs are excellent for towing applications and significantly improve rear load capacity and towing stability on the LandCruiser 105 Series. They reduce rear sag when towing caravans or trailers, maintaining correct suspension geometry for safer handling and braking. However, the towing weight itself should NOT be included when selecting your spring rate — only calculate constant load (permanently fitted accessories). For maximum towing versatility and the ability to adjust support based on varying trailer weights, consider adding airbag suspension to work alongside these coil springs for fine-tuned load leveling.
Control arm upgrades are not mandatory for rear coil spring replacement on the LandCruiser 105 Series, as the rear uses a live axle coil spring setup rather than independent suspension with control arms. However, if you're achieving significant lift (4+ inches) or building a comprehensive suspension upgrade, you may want to inspect and potentially replace worn rear radius arm bushings, panhard rod bushings, and trailing arm bushings to maintain correct geometry and handling. For front suspension upgrades that do utilize control arms, upgraded components become more important with increased lift heights.
Yes, a complete four-wheel alignment is mandatory after installing these rear coil springs on your LandCruiser 105 Series. While rear coil springs don't directly affect toe alignment like front suspension, changing ride height alters suspension geometry, pinion angle, and weight distribution, which affects overall vehicle handling and tire wear patterns. A professional alignment ensures correct camber, caster, toe settings, and thrust angle across all four wheels. This protects your investment in new tires, ensures predictable handling, and maintains safe braking performance. Most reputable 4WD workshops include alignment in their suspension installation service.
Select your spring rate based solely on your vehicle's constant load — the combined weight of accessories and equipment permanently installed on your LandCruiser 105 rear end. Calculate the total weight of items like rear drawers, dual spare wheels, rear bar and tire carrier, long-range fuel tanks, dual batteries, water tanks, fridge slides, and roof rack permanent loads. Do NOT include occasional loads like camping gear, passengers, or towing weight in this calculation. Once you have your constant load weight in kilograms, contact our suspension experts who can recommend the ideal spring rate to achieve proper ride height without over-springing. Choosing too heavy a spring rate for your actual load results in harsh ride quality and accelerated wear on other components.
These Toughdog rear coil springs will increase rear ground clearance by 2-6 inches depending on load, which significantly improves clearance for larger tires on the LandCruiser 105 Series. Most 105 Series owners can fit 33-inch tires with 2-3 inches of lift and minimal trimming, while 35-inch tires typically require 4+ inches of total lift plus additional modifications like guard trimming and potentially body lifts. Remember that tire fitment depends on total vehicle lift (front and rear combined), wheel offset, tire width, and suspension travel. Rear spring lift alone doesn't guarantee tire clearance — you'll also need appropriate front lift springs and potentially other modifications for balanced fitment.
Toughdog rear coil springs are backed by a comprehensive manufacturer warranty against defects in materials and workmanship, providing peace of mind for your investment. The specific warranty period varies by component type and is detailed in the Toughdog warranty documentation included with your product. Warranty coverage requires professional installation, correct spring rate selection, and normal use conditions. Warranty does not cover damage from incorrect installation, overloading beyond rated capacity, accident damage, or modification. Keep your proof of purchase and installation receipt to validate warranty claims. 4WD Suspension stands behind all Toughdog products with expert support throughout the warranty period.
Absolutely — these Toughdog rear coil springs are designed to maintain excellent on-road ride quality and comfort for daily driving while providing the benefits of increased load capacity and lift height. Unlike leaf spring conversions that can compromise ride comfort, coil springs retain the LandCruiser 105's renowned comfortable ride characteristics when properly matched to your constant load. The progressive rate design provides soft initial compression for empty or lightly loaded driving, then firms up progressively under heavier loads or during towing. When you select the correct spring rate for your actual constant load (not over-sprung), these springs deliver comfortable daily driving, reduced body roll, and improved handling compared to sagging factory springs.
