Not sure if this fits your vehicle or which spring rate to choose? Contact our suspension experts for personalized advice or check our FAQ page for detailed spring selection guidance.
Selecting the correct spring rate is critical for optimal performance and ride quality. Your spring rate should be based on the constant load your FJ Cruiser carries — this means accessories and equipment permanently installed on your vehicle, not occasional loads like camping gear or towing loads. Common rear constant load items include rear drawers and storage systems, dual battery setups, water tanks, long-range fuel tanks, heavy-duty rear bars, spare tire carriers, and permanently mounted recovery equipment. Occasional loads such as camping gear, passengers, and trailer towing should NOT be factored into your spring rate selection, as oversizing springs will result in harsh ride quality and potential damage to other suspension components. If you're unsure about your constant load weight, our team can help you calculate the correct spring rate for your specific setup.
Professional installation by a qualified mechanic or experienced 4WD suspension specialist is strongly recommended for coil spring replacement. Installation requires specialized spring compressor tools and proper safety equipment, as compressed springs store significant energy. A wheel alignment is mandatory after installation to ensure correct steering geometry and prevent premature tire wear. Allow a 500km break-in period for springs to settle and reach their optimal ride height — it's normal for new springs to sit slightly higher initially. For FJ Cruisers with significant lift or heavy constant loads, consider pairing these rear springs with upgraded control arms to maintain proper suspension geometry and maximize component longevity.

These Toughdog rear coil springs are specifically engineered for the Toyota FJ Cruiser GSJ15 series produced from 2011 to 2018 with the 4.0L V6 petrol engine. They are a direct replacement for the factory rear coil springs and require no modifications for fitment. The springs are designed to work with the standard rear suspension geometry and mounting points. If you have a heavily modified FJ Cruiser or are unsure about compatibility with aftermarket suspension components, please contact our team to confirm fitment before ordering.
These Toughdog rear coil springs are primarily designed for load compensation and ride height restoration rather than lift. The actual height change depends on the spring rate you select and your vehicle's current condition. On a sagging FJ Cruiser with worn factory springs, these will restore factory ride height or slightly exceed it depending on constant load. If you've added significant constant accessories like rear drawers and heavy-duty bars, the appropriate spring rate will level your vehicle and prevent rear sag. For those seeking suspension lift, these springs work perfectly as part of a complete lift kit system when combined with appropriate front suspension components.
This kit includes a pair (2 pieces) of Toughdog heavy-duty rear coil springs specifically designed for the Toyota FJ Cruiser. Each spring features high-grade spring steel construction with corrosion-resistant powder coat finish and spring rate identification tags. The kit includes a comprehensive fitment and installation guide to assist with proper installation. Please note that spring compressor tools, upper and lower spring seats (if replacement is needed), and installation hardware are not included and must be purchased separately if required. All springs are supplied as a matched pair to ensure balanced rear suspension performance.
Yes, these Toughdog rear coil springs significantly improve towing capability by providing increased load support and reducing rear-end sag when towing caravans, trailers, or camper trailers. However, it's important to understand that spring rate selection should be based on constant load only, not towing loads. The springs will provide a firmer foundation for towing, but for frequent heavy towing, we recommend complementing these springs with airbag suspension for adjustable load support and the ability to level your vehicle when connected to a trailer. Always ensure your total vehicle weight including towing loads remains within Toyota's specified GVM and GCM ratings.
For a standard spring replacement on an FJ Cruiser maintaining near-factory ride height, upgraded control arms are not mandatory but are beneficial for improved suspension geometry and longevity. However, if you're installing heavier spring rates to accommodate significant constant loads, or combining these springs with other lift components, upgraded control arms become increasingly important to maintain proper suspension geometry and reduce wear on factory bushings. Upgraded control arms also provide improved articulation, better caster angle correction, and enhanced durability for serious touring and off-road use. Our suspension specialists can assess your specific setup and recommend whether control arm upgrades would benefit your application.
Yes, a professional four-wheel alignment is absolutely mandatory after installing new rear coil springs on your Toyota FJ Cruiser. While rear coil spring replacement primarily affects ride height, any change in suspension geometry can impact wheel alignment angles including toe, camber, and the relationship between front and rear axles. Proper alignment ensures even tire wear, optimal handling characteristics, and safe vehicle operation. The alignment should be performed after the springs have settled (approximately 500km of driving) to account for the natural settling process. Driving without proper alignment can result in premature tire wear, poor handling, and increased stress on suspension components.
Yes, Toughdog rear coil springs for the FJ Cruiser are available in multiple spring rates to match your specific constant load requirements. When ordering, you'll need to calculate the total weight of permanently installed accessories in your vehicle such as rear drawers, dual battery systems, water tanks, rear bars, and recovery equipment. It's critical to select spring rates based only on constant load — not occasional loads like camping gear or towing weights. Selecting an unnecessarily heavy spring rate will result in harsh ride quality, reduced comfort, and potential damage to other suspension components. Our team can help you calculate your constant load and select the optimal spring rate for your specific FJ Cruiser configuration.
These Toughdog rear coil springs alone will provide minimal additional tire clearance, as they're primarily designed for load compensation and ride height restoration rather than significant lift. The FJ Cruiser can accommodate slightly larger tires than stock with these springs if your vehicle was previously sagging, but for substantial tire size increases, you'll need a complete suspension lift kit including front and rear components. The actual tire clearance depends on your wheel offset, tire width, and driving conditions — what fits statically may still rub under full compression or articulation. If your goal is fitting larger tires for off-road use, consult with our suspension experts about complete lift solutions that provide proper clearance and maintain suspension geometry.
Toughdog rear coil springs are backed by Toughdog's comprehensive manufacturer warranty, which covers defects in materials and workmanship under normal use conditions. The warranty protects against spring failure, breakage, and manufacturing defects when the springs are installed correctly and used within their designed load parameters. Warranty coverage requires professional installation with proof of purchase and does not cover damage from overloading, incorrect spring rate selection, improper installation, or abuse. Toughdog's Australian-based warranty support ensures quick resolution of any covered issues. For specific warranty duration and terms, refer to the documentation included with your springs or contact our team for detailed warranty information.
Absolutely — these Toughdog rear coil springs are engineered to provide excellent ride quality for daily driving, highway cruising, and urban commuting while delivering enhanced load capacity when needed. Toughdog's progressive spring rate technology ensures the springs remain comfortable when unladen but provide firm support under load, making them ideal for vehicles that serve dual purposes as daily drivers and weekend tourers. When properly matched to your constant load requirements, these springs actually improve highway stability, reduce body roll in corners, and enhance overall handling compared to worn factory springs. The key to maintaining daily driving comfort is selecting the correct spring rate based on your actual constant load rather than overspeccing for occasional loads.
