Toughdog 6 Inch Rear Coil Springs for Nissan Patrol GU/Y61 Wagon

These springs are rated to provide approximately 6 inches (150mm) of rear lift when correctly loaded with your constant accessory weight. The actual lift height you achieve will depend on several factors including which spring rate you select, your total constant accessory load, and your vehicle's current condition. An unladen vehicle will sit higher than the rated lift, while a fully loaded tourer will settle to the designed height. It's essential to match the spring rate to your actual constant load to achieve the advertised lift and optimal ride quality. Springs typically settle 10-20mm during the first 500-1000km break-in period.

This kit includes a pair (2 springs) of Toughdog heavy duty rear coil springs manufactured to your selected spring rate specification, complete with corrosion-resistant powder coat finish. Spring isolators and seat hardware are included where applicable to the selected rate. This is a rear spring set only — it does not include front coil springs, shock absorbers, extended brake lines, u-bolts, shackles, or other suspension components that may be required for a complete 6 inch lift installation. We recommend reviewing our complete Patrol GU/Y61 suspension packages or consulting with our team to ensure you have all necessary components for your build.

Yes, these heavy duty coil springs are excellent for towing applications, providing superior load support compared to standard springs and helping to maintain level ride height when hitched. However, it's critical that you select the correct spring rate based on your constant accessory load only — do not include trailer tongue weight in your spring rate calculation as this is a variable load. For optimal towing performance and adjustability, many Patrol owners pair these springs with supplementary airbag suspension, which allows you to fine-tune rear height and support based on varying trailer weights. If you tow regularly or near maximum capacity, consult our team about the ideal spring rate and whether airbag assistance would benefit your specific setup.

With a 6 inch lift, upgraded or adjustable control arms are highly recommended and may be essential depending on your specific build and intended use. A lift of this magnitude significantly alters suspension geometry, which can affect caster angles, ball joint angles, CV axle angles (on IFS models), and overall handling characteristics. Adjustable control arms allow proper correction of these geometry changes, improve wheel alignment capability, and help prevent accelerated wear on ball joints and CV joints. While not always mandatory for the rear (where these springs fit), a complete 6 inch lift package typically requires geometry correction components front and rear. Our suspension specialists can assess your complete build requirements and recommend appropriate complementary components.

Absolutely — a full four-wheel alignment is mandatory after installing any lift springs, particularly with a substantial 6 inch lift. The change in ride height will alter your Patrol's suspension and steering geometry, affecting camber, caster, and toe angles which directly impact handling, steering feel, tyre wear, and safety. Professional alignment should be performed after installation and again after the 500-1000km break-in period once the springs have fully settled to their final height. Attempting to drive without proper alignment can result in rapid tyre wear, poor handling characteristics, and potentially dangerous steering behaviour, especially when loaded or towing. Always use a reputable 4WD alignment specialist familiar with lifted Patrols.

Yes, these Toughdog rear springs are available in multiple spring rates to accommodate different constant accessory loads — this is one of their key advantages. To select the correct rate, you must accurately calculate the total weight of all permanently fitted rear accessories: rear bars, tow hitch, dual battery systems, fridge slides, drawer systems, roof racks with awnings, long-range tanks, spare wheel carriers, and water tanks. Weigh these items or use manufacturer specifications to get an accurate total. It's crucial to include only constant loads — do not factor in passengers, camping gear, food, or trailer weights as these are variable. Selecting a spring rate too heavy for your actual load will result in excessive ride height and harsh ride quality, while too light will cause sagging and reduced handling performance.

A 6 inch lift on the Nissan Patrol GU/Y61 Wagon typically allows fitment of 35-37 inch tyres, though the exact size depends on several factors including wheel offset, tyre width, front lift height, and whether you perform additional modifications like fender trimming or wheel arch modifications. Keep in mind that these are rear springs only — you'll need equivalent front lift to achieve a level stance and balanced tyre clearance. Larger tyres may also require diff gearing changes, recalibrated speedometer, upgraded brakes, and potentially modified suspension components to maintain safe handling. We recommend consulting with experienced Patrol builders or our technical team to plan your complete wheel and tyre package around your suspension lift to ensure proper clearance at full articulation.

Toughdog suspension components are backed by the manufacturer's comprehensive warranty covering defects in materials and workmanship under normal use conditions. Specific warranty terms and duration vary by component type and application, so it's important to retain your purchase documentation and register your purchase with Toughdog if required. The warranty typically covers manufacturing defects but excludes damage from incorrect installation, inappropriate spring rate selection, overloading beyond rated capacity, accident damage, or modifications. To maintain warranty validity, ensure professional installation by a qualified technician, select the correct spring rate for your application, and follow all recommended break-in and maintenance procedures. Our team can provide specific warranty details for this product at time of purchase.

While these springs are engineered to maintain acceptable on-road manners when correctly matched to your load, a 6 inch lift is considered extreme and will noticeably change your Patrol's driving characteristics compared to standard or moderate lift configurations. On-road handling will be affected by the higher centre of gravity, altered weight transfer during cornering, and stiffer spring rates required for proper load support. When correctly set up with appropriate shock absorbers, proper alignment, and the right spring rate for your constant load, these springs can provide acceptable daily driving comfort for owners who prioritize capability and ground clearance over sports-car handling. However, if your Patrol is primarily a daily driver with minimal off-road use, you may find a 2-3 inch lift kit offers a better balance of capability and everyday comfort.
