Selecting the correct spring rate is critical for optimal performance, ride quality, and component longevity. When ordering, choose your spring rate based on constant accessory load only — this means weight that is permanently fitted to your vehicle, not occasional loads like passengers, camping gear, or towing equipment. Common constant loads for the Nissan Patrol MQ/MK include bull bars, rear bars, roof racks with lighting, dual battery systems, long-range fuel tanks, drawer systems, and permanently mounted recovery equipment. Occasional loads like caravans, camper trailers, or weekend camping gear should not be factored into spring rate selection — instead, consider supplementing with airbag suspension for variable load management. Selecting an unnecessarily heavy spring rate will result in harsh ride quality when unloaded and may cause accelerated wear to other suspension components including bushings and shocks.
Professional installation by a qualified 4WD suspension specialist is strongly recommended to ensure correct fitment, torque specifications, and safety compliance. While experienced DIY mechanics with appropriate tools can perform the installation, proper spring compressor equipment and safety procedures are essential when working with leaf springs under tension. A full four-wheel alignment is mandatory after installation to restore correct suspension geometry and prevent premature tyre wear. Allow a 500km break-in period for springs to settle and bushings to seat properly before final ride height assessment. For Patrol owners upgrading to larger tyres or seeking improved handling, consider pairing these springs with upgraded suspension components including quality shock absorbers and polyurethane bushings for a complete rear-end transformation.
Toughdog has earned its reputation as Australia's most trusted 4WD suspension brand through decades of proven performance in the country's harshest conditions. Every component is engineered with Australian terrain in mind — from corrugated dirt roads and bulldust to beach sand, river crossings, and rocky mountain tracks — and backed by comprehensive manufacturer warranty and local technical support. The full Toughdog suspension range is trusted by grey nomads touring the outback, tradespeople relying on daily reliability, and weekend warriors seeking adventure, making it the go-to choice for Australians who demand durability, performance, and value.
These rear leaf springs are perfect for Nissan Patrol MQ/MK owners who have experienced rear-end sag from worn factory springs, carry constant accessory loads like bull bars and touring equipment, or need to restore proper ride height and load-carrying capability. Ideal for tradespeople using their Patrol as a workhorse, grey nomads setting up for extended touring with permanent accessories, and classic 4WD enthusiasts maintaining or restoring their MQ/MK to reliable daily-driver status. For owners who tow caravans or trailers occasionally rather than carrying constant load, consider supplementing these springs with adjustable airbag suspension for on-demand load support without compromising unladen ride quality.

Yes, these Toughdog rear leaf springs are specifically engineered for Nissan Patrol MQ (1980-1987) and MK (1980-1988) series models as a direct rear axle replacement. They're manufactured to original equipment specifications with factory-style spring eyes and mounting points for straightforward fitment without chassis modifications. If you're unsure about your specific Patrol variant or have made modifications to your vehicle, our suspension experts can verify compatibility — simply contact us with your VIN or build details for confirmation before ordering.
These Toughdog leaf springs are primarily designed to restore factory ride height on Patrols with sagging or worn original springs, rather than provide significant lift. Depending on your current spring condition and constant accessory load, you can expect to restore 25-50mm of lost ride height, bringing your Patrol back to original specifications. If you're seeking additional lift for larger tyres or increased ground clearance, these springs can be combined with other components as part of a complete suspension system, or you may want to explore dedicated lift options from our range.
This kit includes a pair (left and right) of heavy-duty rear leaf springs with factory-style spring eyes, high-quality bushings, multi-leaf construction, corrosion-resistant powder coat finish, and spring centre bolts and clips. U-bolts are sold separately as many customers prefer to reuse original hardware or upgrade to heavy-duty options depending on their specific setup. Shock absorbers are also sold separately, allowing you to pair these springs with quality shocks that match your driving style and load requirements for optimal performance.
These springs are designed to handle constant accessory loads permanently fitted to your Patrol, but occasional towing loads should not be factored into spring rate selection. For regular towing of caravans, camper trailers, or heavy trailers, we strongly recommend supplementing these leaf springs with adjustable airbag suspension, which allows you to increase load support when towing without compromising ride quality when your Patrol is unladen. This combination provides the best of both worlds — restored factory performance for daily driving with on-demand load support for towing adventures.
While these leaf springs can be installed as a standalone upgrade to restore ride height and load capacity, pairing them with new shock absorbers is highly recommended for optimal performance, especially if your current shocks are worn or original. Quality shocks properly matched to your spring rate will dramatically improve ride quality, control, and off-road capability. Depending on your Patrol's condition and how you use it, you may also want to inspect and replace worn bushings, shackles, and mounting hardware to ensure your entire rear suspension system is performing as a cohesive unit.
Yes, a full four-wheel alignment is mandatory after installing new leaf springs to restore correct suspension geometry and ensure your Patrol tracks straight and true. Even though you're only replacing rear springs, changes to rear ride height affect the entire vehicle's geometry and can cause premature tyre wear, poor handling, and steering issues if alignment is neglected. Professional alignment should be performed after the springs have settled during the initial 500km break-in period, allowing for accurate adjustment once the springs have compressed to their final operating height under normal driving conditions.
Yes, Toughdog typically offers multiple spring rate options to match your specific constant accessory load, though you should select based only on weight permanently fitted to your vehicle. When ordering, calculate the total weight of bull bars, rear bars, roof racks with lighting, long-range fuel tanks, drawer systems, dual batteries, and other fixed accessories — do not include occasional loads like passengers, camping gear, or towing equipment. Our team can help you calculate your constant load and recommend the appropriate spring rate to ensure optimal ride quality and performance for your specific Patrol setup.
These springs primarily restore factory ride height rather than provide significant lift, so tyre clearance improvements will be modest compared to sagging worn springs. If your goal is fitting substantially larger tyres, you'll likely need additional lift components such as body lifts, diff drop kits, or a complete suspension lift kit depending on your target tyre size. That said, restoring proper ride height can provide enough clearance for a modest tyre size increase — typically one size up from factory specifications — without major rubbing issues. Contact our team with your target tyre size for specific fitment advice.
Toughdog leaf springs are backed by comprehensive manufacturer warranty covering defects in materials and workmanship, reflecting the brand's confidence in Australian engineering and quality control. Warranty terms typically cover the springs under normal operating conditions when installed correctly by a qualified technician and used within designed load specifications. Keep your proof of purchase and installation receipts, as warranty claims require verification that the product was professionally fitted and maintained according to manufacturer guidelines. For specific warranty duration and terms, contact us directly or refer to the warranty documentation included with your springs.
These Toughdog rear leaf springs are absolutely suitable for daily driving and are engineered to provide a balanced ride quality for mixed-use applications including commuting, highway touring, and off-road adventures. While they're built to handle heavy loads and tough conditions, they maintain reasonable compliance when unloaded, avoiding the harsh ride associated with poorly matched or over-rated springs. Many Patrol MQ/MK owners use these springs as their everyday suspension solution, appreciating the restored ride height, improved load capacity, and durability without sacrificing comfort for daily errands, work commutes, or weekend trips to the coast or bush.
