Toughdog Front Suspension Struts for 300 Series Toyota Landcruiser (Pair)

These Toughdog front struts themselves do not provide lift height - they are dampers designed to control spring movement and provide superior ride quality. The actual lift height is determined by the coil springs you pair with these struts, which are sold separately. When matched with appropriately rated lifted coil springs, the 300 Series can typically achieve 40-75mm of front lift depending on spring selection and loaded vehicle weight. The advantage of this component approach is that you can select springs specifically matched to your constant accessory load (bull bar, winch, etc.) while these struts provide the damping control needed for that setup.

This kit includes a pair (left and right) of Toughdog engineered front suspension struts, upper mounting hardware, compression bump stops, protective dust boots and complete installation instructions with torque specifications. The struts come pre-assembled ready to fit once paired with your chosen coil springs. Please note that coil springs are sold separately and must be selected based on your vehicle's constant front-end accessory weight - our technical team can help you choose the correct spring rate if you're unsure. All required bushings and mounts are included, though you may need basic consumables like brake cleaner and grease during installation.

Absolutely - these Toughdog front struts are engineered to handle the increased loads and dynamic stresses associated with towing heavy caravans and trailers with the 300 Series Landcruiser. The heavy-duty internal valving and gas-charged design maintain consistent damping performance even under the nose-weight transfer and increased braking forces experienced when towing at the Landcruiser's maximum towing capacity. The struts work to control front-end dive during braking and maintain steering precision under tow, which is essential for safe handling with heavy trailers. For optimal towing performance, pair these front struts with appropriate rear suspension upgrades including rated springs or airbag suspension to maintain level vehicle attitude.

If you're running a modest lift (up to 50mm) with minimal additional front-end weight, the factory control arms will generally remain adequate when fitted with these Toughdog struts. However, for lifts beyond 50mm or when running heavy bull bars, winches and significant front accessories, upgraded aftermarket control arms become highly recommended to maintain correct ball joint angles and prevent binding. Incorrect suspension geometry can lead to premature ball joint wear, poor steering feel and accelerated tyre wear. Upgraded control arms also typically feature stronger construction and better bushing materials than factory components, improving durability under the increased loads of touring and off-road use. Our team can assess your specific setup and advise whether control arm upgrades are beneficial for your application.

Yes, a complete four-wheel alignment is absolutely mandatory after installing these front struts, even if you're replacing them with identical components. During strut replacement, front-end geometry including camber, caster and toe settings will be disturbed and must be professionally reset to manufacturer specifications. This is particularly critical on the 300 Series Landcruiser which features sophisticated suspension geometry for its refined on-road handling characteristics. Skipping the alignment will result in rapid and uneven tyre wear, poor steering feel and potentially unsafe handling characteristics. The alignment must be performed with the vehicle at normal operating weight including driver, typical fuel load and any constant accessories fitted. Most professional suspension installers will include alignment as part of their installation service.

Yes - in fact, selecting the correct spring rate to match your vehicle's constant accessory weight is essential for optimal performance with these Toughdog struts. Springs are sold separately, allowing you to choose from standard, medium or heavy-duty rates depending on your front-end load. A lightly accessorised 300 Series with no bull bar might suit standard or medium-duty springs, while a vehicle with a full aluminium bull bar, winch, dual batteries and long-range tank would require heavy-duty front springs. These struts are valved to work effectively across this range of spring rates, providing appropriate damping control regardless of which spring option you select. Our technical team can calculate your front axle load and recommend the ideal spring rate for your specific setup to ensure you maintain correct ride height and optimal handling.

While these struts themselves don't determine tyre clearance - that's controlled by your lift height achieved through spring selection - they do enable you to run lifted springs that create clearance for larger tyres. When paired with appropriately lifted coil springs (typically 50-75mm), the 300 Series can accommodate tyres up to approximately 285/70R17 or 33-inch diameter with minimal to no trimming required, depending on wheel offset. Larger tyres may require minor guard trimming and potentially aftermarket upper control arms to maintain proper geometry. Remember that significantly larger or heavier tyres will affect your vehicle's handling, braking performance and fuel economy, so ensure your entire suspension system including these struts and matched springs is rated for your intended setup. Always verify clearance at full lock and compression before committing to expensive tyre purchases.

These Toughdog front suspension struts are covered by Toughdog's comprehensive manufacturer warranty, protecting you against defects in materials and workmanship under normal use conditions. The warranty coverage is valid from the original date of purchase and requires proof of purchase and professional installation by a qualified technician. Warranty claims are handled directly through 4WD Suspension Australia with full support from Toughdog's Australian-based technical team. The warranty does not cover damage from accidents, improper installation, modifications to the product, or wear and tear from normal use over time. For complete warranty terms and conditions including duration specifics, please contact our team or refer to the documentation included with your struts. Maintaining service records and evidence of proper installation practices will ensure swift warranty claim processing should any issues arise.

Absolutely - these Toughdog front struts are engineered to deliver excellent comfort and refinement for daily driving while maintaining the performance capabilities needed for touring and off-road use. The multi-stage internal valving provides small-bump compliance that absorbs road imperfections, speed humps and highway expansion joints without harshness, maintaining the 300 Series' reputation for long-distance comfort. Unlike some competition-focused suspension options that compromise on-road comfort for maximum off-road capability, these struts strike an excellent balance suitable for vehicles that spend the majority of their time on sealed roads with periodic touring and off-road adventures. They eliminate the common issues of worn factory struts including front-end dive under braking, body roll in corners and wallowing ride quality, while maintaining civilised highway manners. If your 300 Series is primarily a daily driver that occasionally ventures off-road, these struts represent an ideal upgrade path.
