These adjustable shocks are designed to work with standard or upgraded rear leaf springs, with adjustment range compensating for varying constant loads. Common rear accessories affecting spring selection include steel bullbars, dual spare wheel carriers, long-range fuel tanks, drawer systems, roof racks with rooftop tents, camping equipment, recovery gear, water tanks, and rear-mounted toolboxes. If you're consistently running over 200kg of rear accessories, consider pairing these shocks with heavy-duty leaf springs for optimal ride height and load support.
Professional installation by a qualified 4WD suspension specialist is strongly recommended for 45 Series LandCruiser applications to ensure correct torque specifications and bushing orientation. Wheel alignment check is not typically required for rear shock-only replacement unless ride height changes significantly. Allow 500km break-in period for foam cell settling and seal bedding before making fine adjustment changes. For vehicles with significant lift or modified spring rates, consider upgrading to heavy-duty steering dampers to maintain steering control and stability.

These rear adjustable shocks are perfect for 45 Series LandCruiser owners who regularly vary their rear load — from weekend camping trips to extended outback touring with full recovery equipment. Classic 4WD enthusiasts restoring or maintaining vintage LandCruisers will appreciate the ability to fine-tune ride height as original springs age or when switching between unladen daily driving and loaded expedition setups. For serious load carriers regularly towing heavy off-road caravans or managing tradesman equipment, consider supplementing with airbag suspension systems for ultimate load control and ride height adjustment.
All Toughdog products are held in Australian stock for fast dispatch nationwide, with expert technical support available to help you select the right suspension components for your specific application and load requirements. Whether you're building a classic 45 Series tourer or maintaining a working heritage LandCruiser, these adjustable rear shocks deliver the performance and reliability you need.

These Toughdog rear adjustable shocks are specifically engineered for 45 Series Toyota LandCruiser models including FJ45, HJ45, and BJ45 variants manufactured between 1960-1984. They are designed as direct rear axle replacements for the original leaf spring suspension configuration. The shocks use OE mounting positions and require no modifications for fitment. If you have a non-standard suspension setup or significant modifications, we recommend contacting our technical team to confirm compatibility before ordering.
These are adjustable-height shock absorbers rather than lift shocks — they feature external adjustment mechanisms that allow you to fine-tune rear ride height by approximately 25-40mm to compensate for varying loads, spring sag, or accessory weight. The actual lift height of your vehicle is determined by your rear leaf spring pack, not the shocks. These shocks work with standard, raised, or heavy-duty leaf springs, with the adjustment allowing you to level the vehicle when carrying different loads. They maintain proper damping performance across the full adjustment range.
This package includes two complete Toughdog rear adjustable shock absorbers with pre-installed mounting bushes, dust boots, and all necessary hardware for installation. Each shock comes nitrogen-charged and ready to fit directly to your 45 Series LandCruiser rear axle. Installation instructions and warranty documentation are included with every pair. Note that rear leaf springs, U-bolts, spring shackles, and any other suspension components are sold separately and not included in this shock absorber package.
Yes, these Toughdog adjustable shocks are excellent for towing applications thanks to their increased damping force and adjustable ride height capability. The foam cell technology maintains consistent performance under the sustained compression loads experienced when towing, while the multi-stage valving controls body roll and pitch. The external adjustment allows you to raise the rear ride height to compensate for tongue weight and maintain level vehicle stance. For regular heavy towing exceeding 2000kg, we recommend combining these shocks with upgraded heavy-duty leaf springs and considering supplementary airbag suspension for maximum load control.
The 45 Series LandCruiser uses leaf spring suspension front and rear without independent control arms, so no control arm upgrades are required or applicable for this shock installation. These shocks are a direct replacement for your original rear dampers and work within the existing leaf spring suspension geometry. If you're planning a comprehensive suspension upgrade including front modifications, our technical team can advise on complementary components. The shocks install using the factory upper and lower mounting points with no suspension geometry changes required.
Wheel alignment is generally not required when replacing rear shock absorbers only, as they do not directly affect suspension alignment angles on a leaf spring rear axle. However, if you're also replacing rear leaf springs, adjusting ride height significantly, or if your vehicle hasn't had an alignment check in over 12 months, it's good practice to have alignment inspected. The front axle alignment should always be checked if you notice uneven tyre wear or steering pull. Always torque all suspension fasteners to manufacturer specifications and conduct a thorough safety inspection after installation.
These Toughdog adjustable shocks come with a factory-preset damping curve optimized for general touring and load-carrying applications — the damping rates are not adjustable. The "adjustable" designation refers to the external ride height adjustment mechanism that allows you to change shock length to compensate for different loads and maintain level ride height. If you require specific custom damping for competition use or extreme load scenarios, contact our suspension specialists who can recommend alternative shock options. The standard valving suits 90% of touring, daily driving, and moderate off-road use perfectly.
These shock absorbers themselves do not provide suspension lift — tyre clearance is determined by your leaf spring lift height, body clearance, and wheel offset. If you're running standard leaf springs, these shocks will maintain your current ride height (with minor adjustment capability). For fitting larger tyres on a 45 Series LandCruiser, you'll typically need raised leaf springs front and rear, possible body mount modifications, and may require trimming or flares depending on tyre size. The shocks will provide proper damping control with larger tyres once appropriate lift and clearance modifications are completed. Consult our parts finder for complete lift solutions for your specific tyre size goals.
All Toughdog shock absorbers are covered by a comprehensive manufacturer warranty against defects in materials and workmanship, typically providing 12-24 months coverage depending on application (confirm specific terms at time of purchase). The warranty covers manufacturing faults, seal failures, and structural defects under normal operating conditions. Warranty does not cover damage from incorrect installation, accident, competition use, or modifications. Toughdog's Australian presence ensures warranty claims are handled locally with minimal downtime. Always retain your proof of purchase and register your product online for full warranty protection.
Absolutely — these Toughdog adjustable shocks are specifically valved to deliver excellent on-road comfort for daily driving while maintaining control for off-road touring and load carrying. The multi-stage valving provides soft initial compression for absorbing small road imperfections and maintaining ride comfort, while the progressive damping controls larger bumps and body motion. Many 45 Series LandCruiser owners use these as their daily driver suspension, appreciating the smooth highway manners and reduced body roll compared to worn original shocks. The foam cell design eliminates the harsh ride associated with budget gas shocks while providing superior fade resistance for sustained highway driving with loads.
Perfect upgrade for my work rig
Been running these Toughdog adjustable shocks on my 45 for about three months now, carting tools and materials around sites daily. The adjustability is brilliant - I can stiffen them up when I'm loaded to the gills with gear, then dial it back for weekend beach trips. Ride quality is heaps better than the old worn-out stockies, and they handled the install without any dramas.(5)
Perfect for Remote Outback Work
Just finished a 3-week Cape York trip and these Toughdog adjustable shocks handled the corrugations and rough tracks brilliantly on my 45 Series. The adjustability meant I could dial them in for different loads throughout the trip, which made a massive difference on those bone-shaking inland tracks. Fitment was spot-on with no dramas, and they've completely transformed the rear end stability when I'm loaded up with recovery gear and water.(5)
Perfect Upgrade for Our Family Adventures
Finally upgraded to these Toughdog adjustable rear shocks for our 45 Series Cruiser and what a difference on our last trip down to the Victorian High Country. The adjustability is brilliant - could dial them in perfectly whether we're loaded up with camping gear and the kids' stuff or running light. Ride quality is noticeably smoother over corrugations and the old girl handles so much better now, especially with the camper trailer on the back.(5)
Perfect upgrade for our touring setup
Fitted these Toughdog adjustable shocks to our 45 Series Cruiser before our Cape York trip and they handled the corrugations beautifully. The adjustability made it easy to dial in the perfect setting when loaded up with camping gear and water, and they've transformed the rear end stability when towing our camper trailer. Delivery was quick to regional NSW and fitment was straightforward with basic tools.(5)
