Selecting the correct spring rate is critical for optimal performance and ride quality. Your spring rate should be based on the constant load your Ranger carries — this means accessories and equipment that remain in your vehicle permanently, not occasional loads. Common constant load items include aluminium or steel canopy/cab chassis bodies, bull bars, long-range fuel tanks, dual battery systems, drawer systems, roof racks with awnings, and permanently installed water tanks. Occasional loads such as camping gear for weekend trips, esky contents, or periodic trailer towing should NOT be factored into your spring rate selection. Choosing springs rated for heavier loads than your actual constant load will result in a harsh ride, increased component wear, and potential damage to other suspension parts.
Professional installation by a qualified mechanic or experienced 4WD workshop is strongly recommended for leaf spring replacement. Installation requires proper lifting equipment, spring compressors, and torque specifications to be followed precisely. A wheel alignment is mandatory after fitting leaf springs to ensure correct camber, caster, and toe settings, preventing premature tyre wear and maintaining vehicle handling characteristics. Allow a 500km break-in period for springs to settle and bushings to seat properly before reassessing ride height and performance. Consider pairing these springs with upgraded shock absorbers to maximize ride quality and control under all load conditions.
Toughdog has earned its reputation as Australia's number one suspension brand through decades of real-world performance in the harshest conditions our continent can deliver. Every component is engineered with input from Australian 4WD enthusiasts, tested on corrugated outback tracks, coastal sand, and rocky high-country trails to ensure it meets the demands of serious touring and working vehicles. The Toughdog suspension range is backed by comprehensive warranty coverage and supported by a national network of dealers and installers who understand the unique requirements of Australian 4WD owners.
These rear leaf springs are ideal for Ford Ranger PJ/PK owners who have added permanent accessories, tradespeople who carry tools and equipment daily, touring enthusiasts with canopy setups and drawer systems, and drivers who regularly tow caravans or trailers. If your Ranger sits lower at the rear than factory height, suffers from excessive squat under load, or has deteriorated factory springs, this Toughdog upgrade will restore proper ride height and load-carrying capability. For those carrying extremely variable loads or seeking on-demand adjustability, consider supplementing with airbag suspension systems that allow fine-tuning of load support.

These Toughdog rear leaf springs are specifically engineered for Ford Ranger PJ series (2006-2009) and PK series (2009-2011) models across all cab configurations including single cab, extra cab, and dual cab variants. They are direct replacements for factory leaf springs with no modifications required to your chassis or mounting points. To confirm compatibility with your specific Ranger build and accessory setup, use our parts finder tool or contact our team with your VIN number for verification before purchase.
These are replacement leaf springs designed primarily to restore factory ride height and improve load-carrying capacity rather than provide significant lift. If your Ranger currently sits low due to worn factory springs or added weight from accessories, these Toughdog springs will typically restore the rear to factory height or provide 0-25mm of additional lift depending on your current constant load. For more substantial lift requirements, consider a complete lift kit that includes matched front and rear components for balanced suspension geometry and handling characteristics.
This kit includes two heavy-duty Toughdog rear leaf springs with factory-style spring eyes and quality bushings already installed. The springs feature multi-leaf progressive rate design with corrosion-resistant coating applied during manufacturing. Please note that installation hardware including U-bolts, centre bolts, bump stops, and shackles are not included and must be purchased separately or reused from your existing setup if in serviceable condition. We recommend replacing all mounting hardware during leaf spring installation for optimal safety and performance.
Yes, these Toughdog leaf springs are engineered with enhanced load capacity specifically to improve towing performance and reduce rear squat when hauling caravans, trailers, and boats. The progressive rate design allows the springs to maintain comfortable ride quality when unladen while providing increased support as load increases during towing. However, your spring rate selection must be based on your constant accessory load, not towing load, as occasional towing should not dictate spring rate choice. For heavy or frequent towing, consider supplementing with airbag suspension for adjustable load support and level towing stance.
Control arm upgrades are not mandatory when installing replacement leaf springs on Ford Ranger PJ/PK models, as these vehicles use a leaf-sprung rear suspension setup that doesn't typically require control arm modifications for modest lift or load capacity increases. However, if you're planning a complete suspension overhaul or experiencing worn front-end components, upgrading front control arms can improve steering precision, caster angles, and wheel travel. Focus your budget on quality shock absorbers to pair with these leaf springs for maximum ride quality and load control improvements across all driving conditions.
Yes, a full four-wheel alignment is mandatory after installing new leaf springs to ensure your Ranger's suspension geometry is correctly set. While leaf spring replacement primarily affects rear ride height, any change in vehicle stance impacts camber, caster, and toe angles across both axles. Proper alignment prevents premature and uneven tyre wear, ensures optimal handling characteristics, and maintains vehicle stability during highway driving and emergency maneuvers. Have the alignment performed after the springs have settled following approximately 500km of normal driving for the most accurate and lasting results.
Toughdog leaf springs are available in multiple load ratings to suit different constant load configurations, and selecting the correct rate is essential for ride quality and component longevity. When ordering, specify your spring rate based ONLY on permanent accessories and equipment your Ranger carries continuously — canopy, bull bar, long-range tanks, drawer systems, and roof racks. Never select spring rates based on occasional camping loads or towing requirements, as this will result in excessively firm ride quality and potential damage to other suspension components when running unladen. If uncertain about your constant load calculation, contact our team for expert guidance.
These replacement leaf springs primarily restore factory ride height and improve load capacity rather than providing significant lift for larger tyre fitment. If your Ranger is currently sitting low due to worn springs or heavy accessories, these Toughdog springs will bring it back to factory height with potentially 0-25mm of additional clearance. For fitting substantially larger tyres, you'll need a complete lift kit with matched front and rear lift components to provide adequate clearance and maintain balanced suspension geometry. Check your specific tyre size requirements against ride height increases, and remember that larger tyres may also require trimming or body modifications on PJ/PK Rangers.
Toughdog leaf springs are backed by comprehensive manufacturer warranty against defects in materials and workmanship, providing peace of mind for your investment in quality Australian suspension components. Warranty terms cover failure due to manufacturing defects but exclude damage from incorrect installation, overloading beyond rated capacity, accident damage, or normal wear and tear. To maintain warranty validity, ensure professional installation by a qualified mechanic, select appropriate spring rates for your actual constant load, and retain all purchase documentation. Contact us for specific warranty period details and claims procedures should any issues arise with your springs.
Absolutely — these Toughdog leaf springs are engineered to balance load-carrying capability with acceptable ride comfort for daily driving duties. The progressive rate design ensures the springs aren't overly harsh when your Ranger is unladen for commuting and urban use, while still providing the load support needed for work and touring applications. That said, ride quality is heavily dependent on selecting the correct spring rate for your actual constant load — choosing springs rated for heavier loads than you carry will result in a noticeably firmer ride on smooth roads. When paired with quality shock absorbers, these springs deliver comfortable highway cruising, confident cornering, and capable off-road performance.
Perfect Upgrade for Our Loaded Ranger
