Not sure if this fits your vehicle or need help selecting the correct spring rate? Contact our suspension experts for personalised advice or check our FAQ page for detailed fitment information.
Selecting the correct spring rate is critical for optimal ride quality and component longevity. Only consider constant loads fitted to your vehicle permanently — occasional loads, towing equipment, and cargo should not be included in spring rate calculations. Common constant front accessories for the 300 Series LandCruiser include heavy-duty bull bars (25-40kg), winches (30-50kg), upgraded intercoolers, long-range fuel tanks, driving lights, UHF antennas, and upgraded battery systems. Weigh your fitted accessories to determine total constant front load, then select the appropriate spring rating during checkout. Choosing too heavy a spring rate will result in harsh ride quality and potential damage to other suspension components including top mounts and bushings.
Professional installation by a qualified 4WD mechanic is strongly recommended, though experienced DIY installers with appropriate spring compressor tools can complete the job. The pre-assembled design significantly simplifies installation compared to traditional strut rebuilding. Wheel alignment is mandatory after fitting these struts to ensure correct castor, camber, and toe settings for safe handling and even tyre wear. Allow a 500km break-in period for springs to settle and damping characteristics to optimise before making any ride height or handling assessments. For vehicles with significant lift or heavy touring loads, consider pairing these struts with upgraded control arms to restore suspension geometry and improve wheel travel.
Toughdog has earned its reputation as one of Australia's most trusted 4WD suspension brands through decades of real-world testing across outback tracks, corrugated roads, and extreme touring conditions. Every Toughdog component is engineered specifically for Australian vehicles and conditions, with extensive field testing by professional tourers, tradespeople, and mining operators. Comprehensive warranty coverage and Australia-wide dealer support ensure you're covered wherever your adventures take you. Explore the complete Toughdog suspension range for matching rear suspension, shock absorbers, and complete lift kit solutions for your LandCruiser.
These assembled struts are ideal for 300 Series LandCruiser owners who have added front accessories like bull bars and winches and need to restore factory ride height and handling without compromising comfort. Perfect for grey nomad tourers, tradespeople carrying equipment, and families heading bush with camping gear who want reliable suspension performance without a full lift kit. If you regularly carry heavy rear loads or tow caravans, consider complementing these front struts with airbag suspension at the rear for adjustable load support and level towing.

Yes, these Toughdog front assembled struts are specifically engineered for all 300 Series Toyota LandCruiser models from 2021 onwards, including GX, GR Sport, Sahara, and Sahara ZX variants. They're designed as direct OE replacement units using factory mounting points with no modifications required. The struts fit both petrol and diesel engines across the 300 Series range. If you have specific concerns about your vehicle's build date or variant, our technical team can confirm exact fitment before you order.
These are assembled struts designed primarily to restore factory ride height when front accessories like bull bars and winches are fitted, rather than provide significant lift. Depending on the spring rate selected, they typically restore 0-25mm of sag caused by accessory weight. They're not a lift kit, but rather a load-compensating upgrade that maintains proper suspension geometry and ride quality with added front weight. For actual suspension lift on your 300 Series, you'll need a complete lift kit with taller springs and extended shocks.
This kit includes two complete front assembled strut units (left and right), each featuring a Toughdog foam cell shock absorber pre-assembled with a heavy-duty coil spring matched to your selected load rating. All necessary top mount hardware, bearings, bump stops, spring isolators, and protective components are included. The pre-assembled design means you receive ready-to-fit units that significantly reduce installation time. Fitting instructions are provided, though professional installation and post-fitting wheel alignment are strongly recommended.
While these front struts are excellent for supporting constant front accessory loads like bull bars and winches, front suspension doesn't directly support towing loads—that's handled by your rear suspension. These struts will maintain proper front-end geometry and handling while towing, which is important for stability. For optimal towing performance with your 300 Series LandCruiser, you should pair these front struts with upgraded rear suspension such as heavy-duty rear coil springs or adjustable airbags. The correct spring rate selection ensures your front end doesn't sag and compromise towing balance.
For most 300 Series LandCruiser applications using these struts at standard or near-standard height, factory control arms remain adequate and no upgrade is required. However, if you're adding these as part of a larger suspension modification, running very heavy constant loads, or planning significant lift elsewhere in your suspension system, aftermarket control arms can improve suspension geometry and wheel travel. Control arm upgrades are typically more beneficial when running 50mm+ total lift. Our technical team can assess your specific setup and advise if control arm upgrades would provide measurable benefits for your application.
Yes, professional wheel alignment is absolutely mandatory after installing these or any front suspension components on your 300 Series LandCruiser. Even though these are direct replacement units, the installation process and any change in ride height will affect your wheel alignment settings including castor, camber, and toe. Incorrect alignment causes uneven tyre wear, poor handling, and potential safety issues. Book your alignment immediately after installation, then recheck after the 500km break-in period once springs have fully settled to their final height.
Spring rate selection should be based solely on your constant front accessory weight—items permanently fitted to your vehicle like bull bars, winches, upgraded intercoolers, and long-range fuel tanks. Do not include occasional loads, towing equipment, or cargo when calculating spring requirements. Weigh your fitted accessories or check manufacturer specifications to determine total front accessory weight. A typical heavy-duty bull bar and winch combination adds 60-90kg to the front end. Select the spring rating that matches your constant load during checkout—choosing too heavy a spring will result in harsh ride quality and potential component damage.
These assembled struts are designed primarily for load compensation rather than lift, so they provide minimal additional tyre clearance beyond restoring factory height when accessories are fitted. Most 300 Series LandCruisers can accommodate slightly larger tyres (up to approximately 285/70R18) at stock height with minimal rubbing during full lock or compression. For significant tyre size increases beyond factory specifications, you'll need a complete suspension lift kit with taller springs and extended shocks to provide adequate clearance. These struts are perfect for maintaining proper suspension function with your current or slightly upgraded tyre size while carrying front accessories.
Toughdog provides comprehensive manufacturer warranty coverage on these assembled struts, protecting you against defects in materials and workmanship. Specific warranty terms vary by component (shocks typically carry longer warranty periods than springs), and coverage requires professional installation and proper vehicle use. The warranty covers normal 4WD use including touring, off-road driving, and load carrying within rated specifications. Keep your purchase receipt and installation records for warranty claims. For exact warranty terms and conditions specific to this product, contact our team or refer to the included warranty documentation.
Absolutely—these Toughdog assembled struts are engineered to provide excellent on-road comfort for daily commuting and highway touring while also delivering controlled performance off-road. The foam cell shock technology ensures consistent, fade-free damping during extended highway driving, while the carefully matched spring rates maintain ride quality under load. Many 300 Series owners use these struts as their primary suspension setup for daily family transport, weekend adventures, and annual touring trips. The balanced valving delivers a comfortable ride that's noticeably better than worn factory suspension while still providing the control needed for spirited driving and off-road conditions.
