These RALPH rear shocks are designed to work with various spring rates depending on your constant accessory load. When selecting compatible leaf springs, consider your typical rear-end weight including steel trays, canopies, toolboxes, dual spare wheels, long-range fuel tanks, water storage, camping equipment, and drawer systems. Common rear accessories for 79 Series Dual Cabs include aluminium or steel canopies (80-150kg), dual battery systems, fridges, roof racks, rear bars with wheel carriers, and permanent trade fit-outs. For caravan towing or consistent heavy loads, consider pairing these shocks with upgraded rear springs rated 300-500kg above your constant load for optimal ride quality and vehicle stance.
Professional installation by a qualified mechanic or experienced 4WD workshop is strongly recommended for these rear shock absorbers. Wheel alignment is not typically required for shock-only replacement, however suspension geometry should be inspected if installing as part of a complete lift kit upgrade. Allow a 500km break-in period for optimal damping performance as seals bed-in and valving settles. When lifting beyond 50mm, consider upgrading to adjustable control arms to correct castor angles and maintain steering geometry for improved on-road handling and tyre wear characteristics.

These Toughdog RALPH 53mm bore rear shocks are specifically engineered for Toyota 79 Series Landcruiser Dual Cab models from 2007 to current. They're designed as direct bolt-in replacements for factory rear shock positions and are compatible with both standard ride height and lifted configurations up to 2-3 inches. The shocks will fit all 79 Series Dual Cab variants including V8 diesel and petrol models. If you have a Single Cab, Troopy or other 70 Series variant, different part numbers are required.
These are shock absorbers only and do not provide lift height on their own - lift is determined by your leaf spring selection. However, the RALPH 53mm shocks feature extended shaft travel to accommodate lifted configurations up to 50-75mm (2-3 inches) when paired with appropriate raised leaf springs. They also work perfectly with standard factory ride height, providing superior damping performance compared to stock shocks. For optimal performance in lifted applications, ensure your shock travel matches your total lift height to prevent bottoming out or over-extension.
This kit includes two premium Toughdog RALPH 53mm bore nitrogen gas-charged rear shock absorbers with high-quality rubber bushings pre-installed. All necessary mounting hardware and fasteners are included for direct bolt-in installation. The package also includes installation instructions and technical specifications. Please note that rear leaf springs, U-bolts, shackles and other suspension components are sold separately and should be assessed based on your vehicle's current condition and load requirements.
Absolutely - the RALPH 53mm bore design is specifically engineered for heavy-duty towing applications common with 79 Series Landcruisers. The larger 53mm piston diameter provides superior damping force and better heat dissipation under sustained load, making these shocks ideal for towing caravans, camper trailers and equipment trailers up to maximum rated towing capacity. The advanced valve tuning significantly reduces rear-end sway and improves braking stability when towing. For ultimate towing performance, consider pairing these shocks with heavy-duty leaf springs and airbag suspension for adjustable load support.
Control arm upgrades are typically a front suspension consideration and not directly related to rear shock absorber replacement on the 79 Series Landcruiser, which uses a leaf spring rear suspension design. However, if you're installing these shocks as part of a complete lift kit exceeding 50mm, front control arm upgrades may be necessary to correct castor angles and maintain proper steering geometry. The rear suspension will benefit from inspecting your leaf spring bushings, shackles and U-bolts during shock installation to ensure all components are in good condition for optimal performance and safety.
Wheel alignment is generally not required when replacing rear shock absorbers only, as shocks are wear items that don't affect suspension geometry when replaced like-for-like. However, it's good practice to have your suspension inspected during installation to check for worn bushings, bent components or other issues that could affect alignment. If you're installing these shocks as part of a complete lift kit with new springs, or if you're changing ride height significantly, a full four-wheel alignment is strongly recommended to ensure proper toe, camber and castor settings for optimal tyre wear and handling characteristics.
These RALPH 53mm rear shocks are designed to work with a wide range of leaf spring rates from light to heavy-duty applications, giving you flexibility to match your specific load requirements. Spring rate selection depends on your constant accessory weight including canopy, toolboxes, drawer systems, dual batteries, water tanks and typical cargo load. Toughdog and other manufacturers offer 79 Series rear leaf springs in various load ratings typically from medium (200-300kg) to extra heavy-duty (400-500kg constant load). Our suspension experts can help you select the perfect spring rate to match these shocks for your exact setup and usage.
These shock absorbers themselves don't provide lift height - tyre clearance is determined by your leaf spring selection and any body/suspension modifications. However, when paired with appropriate lifted leaf springs (typically 50mm/2-inch lift), these shocks will support running 33-inch tyres on most 79 Series Dual Cabs with minimal trimming. For 35-inch tyres, you'll typically need 75-100mm of lift plus additional modifications including diff breathers, brake line extensions and potentially body mount chops. The extended shaft travel of these RALPH shocks accommodates the increased wheel articulation that comes with larger tyres and lifted suspensions, making them an excellent foundation for a capable touring or work setup.
Toughdog provides comprehensive warranty coverage on these RALPH 53mm rear shock absorbers against manufacturing defects and premature failure under normal operating conditions. The specific warranty period varies by component type and application, typically ranging from 12 months to lifetime warranty depending on the series and usage. Warranty coverage requires professional installation, proof of purchase, and adherence to recommended service intervals. Toughdog's Australian-based warranty support ensures rapid assessment and replacement if issues arise. For complete warranty terms and conditions specific to this product, contact us directly or refer to the documentation included with your shocks.
Yes, these Toughdog RALPH 53mm rear shocks are specifically engineered to deliver excellent performance for both daily driving and off-road touring. The advanced valve tuning provides a comfortable, controlled ride on sealed highways while maintaining the robust damping characteristics needed for corrugated dirt roads, rocky tracks and off-road terrain. Many 79 Series owners use their vehicles as daily drivers for work, school runs and commuting, then head bush on weekends - these shocks excel in both environments. The premium nitrogen gas-charge technology ensures consistent damping performance whether you're cruising at highway speeds or crawling over technical terrain, making them the ideal choice for dual-purpose 79 Series Landcruisers.
