While these shock absorbers are designed to work with factory or upgraded leaf springs, selecting the correct spring rate is crucial for optimal performance based on your constant accessory load. Rear accessories that affect spring selection include steel canopies, dual battery systems, long-range fuel tanks, rear bar and tow gear, drawer systems, recovery equipment, and water tanks. If you're carrying significant constant weight, consider upgrading to heavy-duty leaf springs matched to your specific load requirements — our suspension specialists can recommend the ideal spring rate based on your typical payload.
Professional installation by a qualified 4WD suspension specialist is strongly recommended to ensure correct fitment, torque specifications, and safety compliance on these classic Landcruisers. While experienced DIY mechanics with proper workshop facilities can complete the installation, replacement of rear shock absorbers requires appropriate jacking and axle support equipment. After installation, a 500km break-in period allows seals and bushings to properly bed in — avoid extreme off-road use during this initial period. If you're also upgrading other suspension components such as steering dampers or shackles, ensure all components are replaced together for balanced system performance and handling characteristics.

These Toughdog rear shock absorbers are engineered specifically for all 45 Series Toyota Landcruiser variants including FJ45, HJ45, and BJ45 models produced between 1960 and 1984. They're designed to fit both petrol and diesel engine variants with factory or lightly modified leaf spring rear suspension setups. If your Landcruiser has been significantly modified with custom suspension components, non-standard spring packs, or body lifts, please contact our team to confirm compatibility. These shocks will fit vehicles with original ride height or those with moderate lift kits up to approximately 50mm.
These Toughdog rear shock absorbers are designed as direct factory replacements and do not provide additional lift height on their own — they maintain your current ride height while dramatically improving damping performance and ride quality. If you're looking to increase rear ride height on your 45 Series Landcruiser, you'll need to upgrade to heavy-duty or raised leaf springs, which these shocks are fully compatible with. The extended travel design of these shocks accommodates lift heights up to approximately 50mm when paired with appropriate raised leaf spring packs. For complete lift kits including springs and shocks matched to your specific requirements, browse our range or contact our suspension experts for recommendations.
This kit includes two Toughdog heavy-duty rear shock absorbers supplied as a matched pair, complete with mounting hardware and replacement bushings required for installation on 45 Series Landcruisers. Each shock is pre-filled with high-performance hydraulic oil and nitrogen gas charged for immediate installation. The mounting hardware includes bushings, washers, and fasteners designed specifically for 45 Series fitment — however, some heavily corroded vehicles may require additional chassis mounting hardware available separately. This kit covers rear axle suspension only — front shock absorbers are sold separately as the 45 Series uses different front suspension components.
Yes, these Toughdog rear shock absorbers are engineered for towing applications and will significantly improve stability, control, and comfort when towing trailers, campers, or caravans with your 45 Series Landcruiser. The heavy-duty valving and nitrogen gas charging maintain consistent damping performance under increased loads, reducing trailer sway and improving braking control. For optimal towing performance, particularly with heavier loads exceeding 1,500kg, we strongly recommend pairing these shocks with upgraded heavy-duty rear leaf springs rated for your typical towing weight. Consider adding airbag suspension to the rear axle for adjustable load support and the ability to level your vehicle regardless of tongue weight variations.
The 45 Series Toyota Landcruiser uses a leaf spring rear suspension system and does not have rear control arms, so no control arm upgrades are required when fitting these rear shock absorbers. The front suspension on 45 Series models also uses leaf springs rather than independent suspension with control arms, making this a straightforward shock replacement that doesn't require complementary suspension arm upgrades. However, if you're experiencing wear in other suspension components such as spring bushings, shackles, or U-bolts, this is an ideal time to replace those items while the vehicle is already being serviced. Inspect all mounting points for corrosion or damage before installation, particularly on older restored vehicles.
Replacing rear shock absorbers on a leaf spring suspended vehicle like the 45 Series Landcruiser typically does not affect wheel alignment settings, as alignment is primarily determined by spring positioning, axle location, and front suspension geometry. However, if you're also replacing leaf springs, shackles, or other suspension components at the same time, a full wheel alignment check is recommended to ensure correct tracking and even tyre wear. If your 45 Series is being used as a daily driver, it's good practice to have alignment checked annually regardless of suspension modifications. Always inspect tyre wear patterns after any suspension work — uneven wear can indicate alignment issues or worn suspension bushings requiring attention.
These Toughdog rear shock absorbers are supplied with valving specifically engineered for the 45 Series Landcruiser platform and are not available in different spring rates, as shock absorbers control damping rather than supporting vehicle weight — spring rate selection applies to leaf springs or coil springs. However, if you have specific load carrying or performance requirements, Toughdog offers various leaf spring options with different load ratings and pack configurations that pair perfectly with these shocks. For vehicles with significantly increased constant loads such as heavy canopies, drawers, and touring equipment, we can recommend heavier-rated rear leaf springs to match your typical payload. Contact our suspension specialists to discuss your specific usage requirements and we'll recommend the ideal spring and shock combination.
These Toughdog rear shock absorbers are designed as direct replacements for factory specifications and do not provide additional lift height for tyre clearance on their own. If you want to fit larger tyres on your 45 Series Landcruiser, you'll need to add raised leaf springs to increase ride height and provide additional clearance in the wheel arches — these shocks are compatible with lifted applications up to approximately 50mm. Tyre size options on the 45 Series are also limited by wheel arch design and guard clearance, particularly at full suspension compression and steering lock. Most 45 Series owners can fit tyres up to approximately 33 inches with a 50mm lift and minor guard trimming, though specific fitment depends on your wheel offset and whether body modifications have been performed.
Toughdog rear shock absorbers are backed by a comprehensive manufacturer's warranty covering defects in materials and workmanship — specific warranty terms and duration are provided with your product and should be retained for your records. Warranty coverage requires professional installation by a qualified mechanic or suspension specialist with proper documentation of the installation date and odometer reading. The warranty covers manufacturing defects but does not cover damage from accidents, improper installation, modifications, or use beyond the product's designed specifications. To ensure your warranty remains valid, retain your purchase receipt and installation documentation, and report any concerns immediately — our team can facilitate warranty claims directly with Toughdog if issues arise.
Absolutely — these Toughdog rear shock absorbers excel in daily driving applications and will dramatically improve ride comfort, handling, and safety on sealed roads compared to worn factory shocks. The progressive valving delivers excellent bump absorption over typical road imperfections, speed humps, and potholes while maintaining controlled body movements during cornering and braking. Many 45 Series Landcruiser owners use their vehicles as daily drivers, weekend tourers, or classic car show pieces, and these shocks are perfectly suited to all these applications. The heavy-duty construction ensures long service life even under constant use, while the nitrogen gas charging prevents fade during extended highway driving or when carrying typical loads around town.
Perfect Upgrade for Our Old Cruiser
Finally replaced the worn out shocks on our 45 series and went with these Toughdog rears based on a mate's recommendation. The difference is night and day – much more controlled over corrugations and the back end doesn't bounce around with all our camping gear loaded up anymore. Really happy with the ride quality improvement and they seem like they'll handle our regular Cape York trips without any dramas.(5)
Perfect upgrade for my old girl
Been running these Toughdog rear shocks on my 45 Series for about six months now, carting tools and materials around town daily plus the odd weekend trip out bush. Fitment was spot on and the ride's heaps better than the old worn-out units I had before. Can't beat the value for a proper Aussie-made shock that actually does the job.(5)
Sorted My 45 Series for Remote Trips
Been running these Toughdog rear shocks on my 45 for six months now through the Simpson Desert and Cape York, and they've absolutely transformed the back end. The ride quality is night and day compared to the old worn units, especially when loaded up with long-range fuel and recovery gear. Fitment was spot-on with no dramas, and they've handled the corrugations and creek crossings without missing a beat.(5)
Perfect Upgrade for Our Old Cruiser
Fitted these Toughdog rear shocks to our 45 series before our last trip down to Wilsons Prom and the difference was night and day. The back end doesn't bounce around like it used to, even when we're loaded up with camping gear and the kids' stuff. Really happy with the ride quality both on and off the bitumen, and they were surprisingly easy to install in the driveway.(5)
