Selecting the correct spring rate is critical to achieving optimal ride quality, load capacity, and suspension performance. Toughdog rear coil springs are available in multiple rates designed to accommodate different constant accessory loads—the weight permanently installed in or on your Jeep TJ Wrangler. Common rear accessories that affect spring selection include dual battery systems, rear drawer setups, long-range fuel tanks, water tanks, recovery gear storage, roof racks with loads, spare tire carriers, rear bar upgrades, and permanently mounted camping equipment.
Important: When selecting your spring rate during checkout, choose based only on your constant load—the weight that remains on your vehicle at all times. Occasional loads such as passengers, camping gear loaded for a trip, or towing a trailer should NOT be factored into your spring rate selection, as over-springing will result in harsh ride quality, premature wear on suspension components, and reduced articulation off-road.
Professional installation by a qualified 4WD suspension workshop is strongly recommended for coil spring replacement to ensure correct fitment, safe handling, and proper spring compression procedures. If installing yourself, use appropriate spring compressors rated for coil springs and follow all safety protocols. A wheel alignment is mandatory after installation to ensure correct steering geometry, even wear on tyres, and safe handling characteristics—particularly important on the Jeep TJ Wrangler platform.
Allow a 500km break-in period for springs to settle to their final ride height and spring rate characteristics. During this period, avoid maximum loads and inspect all mounting hardware for correct torque settings. For complete suspension upgrades, consider pairing these rear coil springs with front coil springs, upgraded shocks, and adjustable control arms to maintain correct castor angles and suspension geometry at lifted ride heights.

These Toughdog rear coil springs are specifically engineered for the Jeep Wrangler TJ series manufactured between 1996 and 2006, fitting both 2.5L 4-cylinder and 4.0L 6-cylinder engine variants. They provide direct bolt-in replacement using factory mounting points and spring seats without requiring modifications. If you have a heavily modified Wrangler or non-standard suspension setup, we recommend contacting our team to confirm compatibility. Our suspension experts can verify fitment based on your specific build date and configuration to ensure perfect compatibility.
Toughdog rear coil springs for the Jeep TJ Wrangler are primarily designed for load compensation and improved weight-carrying capacity rather than significant lift height increase. The actual ride height achieved depends on the spring rate you select and your vehicle's constant accessory load—heavier spring rates will maintain or slightly increase ride height when loaded, while lighter rates provide improved comfort for stock-weight vehicles. Most applications will see between 0-25mm of lift compared to worn factory springs, with the primary benefit being restored or enhanced load capacity and ride quality. For dedicated lift applications, these springs work best as part of a complete suspension system paired with front coil springs and shocks.
This kit includes a pair (2 pieces) of Toughdog heavy-duty rear coil springs engineered specifically for the Jeep TJ Wrangler, complete with corrosion-resistant powder coat finish and built to your selected spring rate specification. The springs are supplied ready to install using your existing factory spring seats, isolators, and mounting hardware. Installation hardware, spring seats, isolators, shock absorbers, and other suspension components are not included and should be ordered separately if replacement is required. We recommend inspecting all suspension components during installation and replacing worn bushes, mounts, and hardware to maximise the performance and longevity of your new springs.
Yes, when correctly rated for your constant accessory load, these Toughdog rear coil springs significantly improve towing capability by maintaining proper rear suspension geometry and preventing excessive squat under trailer tongue weight. The key is selecting the appropriate spring rate that accounts for your permanent accessories while leaving capacity for the additional weight transfer from towing. However, springs alone should not be considered a complete towing solution—for frequent towing of caravans, camper trailers, or boats, we strongly recommend combining these springs with airbag suspension for adjustable load support and the ability to level your vehicle under varying loads. Contact our team for spring rate recommendations specific to your towing requirements.
For standard spring replacement without significant lift height increase, factory control arms will generally perform adequately with these Toughdog rear coil springs on the Jeep TJ Wrangler. However, if you're building a complete suspension system with front and rear lift, or if your factory control arms show wear in bushes or ball joints, upgrading to adjustable aftermarket control arms provides significant benefits. Adjustable arms allow precise correction of castor and camber angles, essential for maintaining proper steering feel, tyre wear patterns, and suspension geometry at altered ride heights. If you're achieving more than 25mm of combined lift, upgraded control arms become increasingly important for optimal suspension performance and handling characteristics.
Yes, a full four-wheel alignment is mandatory after installing any coil springs, even when maintaining similar ride height to factory specifications. Changing rear coil springs alters the suspension geometry and can affect thrust angles, toe settings, and overall tracking of your Jeep TJ Wrangler. A professional alignment ensures your vehicle tracks straight, maximises tyre life, provides predictable handling characteristics, and prevents premature wear on steering and suspension components. The alignment should be performed after the 500km break-in period when springs have settled to their final ride height, and should be rechecked if you notice uneven tyre wear or steering pull after installation.
Absolutely—Toughdog engineers these rear coil springs in multiple spring rate options specifically so you can match the springs to your Jeep TJ Wrangler's exact constant accessory load. During checkout, you'll select the appropriate spring rate based on the permanent weight you carry in drawers, dual batteries, water tanks, recovery gear, roof rack loads, and other fixed accessories. It's critical to select based only on constant load—not occasional passengers, camping gear, or towing weight, as over-springing creates harsh ride quality and reduces articulation. If you're unsure which rate suits your setup, our suspension experts can calculate your accessory weight and recommend the optimal spring rate for your specific configuration and intended use.
These Toughdog rear coil springs alone provide minimal lift height (typically 0-25mm depending on spring rate and load), so they won't significantly increase tyre clearance compared to factory specifications. The Jeep TJ Wrangler can generally accommodate 31-inch tyres on factory suspension, with 32-33 inch tyres possible with minor trimming. For larger tyre fitment, you'll need a complete suspension lift kit including front coil springs, extended shocks, and potentially control arm modifications to achieve 50-75mm+ of lift. These rear springs work perfectly as part of such a complete system, providing the load capacity and ride quality to support larger tyres, recovery gear, and touring accessories. Check our full Jeep Wrangler suspension range for complete lift packages engineered for specific tyre sizes.
Toughdog backs these rear coil springs with their comprehensive Australian manufacturer warranty, covering defects in materials and workmanship under normal operating conditions. The specific warranty period and terms are detailed in the documentation included with your springs and cover typical 4WD applications including touring, off-road use, and load carrying within the springs' rated capacity. Warranty claims are assessed by Toughdog's Australian support team and require proof of purchase and evidence that springs were installed correctly and operated within their design parameters. As an authorised Toughdog dealer, 4WD Suspension Australia provides full warranty support and can assist with any claims process, giving you complete confidence in your investment.
Yes, when correctly specified for your constant load, these Toughdog rear coil springs are engineered to provide excellent ride quality for daily driving, highway cruising, and city use while delivering enhanced capability when you head off-road. Toughdog's engineering focus is on versatile performance—comfortable enough for the school run and commute to work, yet tough enough for weekend beach trips, forest tracks, and outback touring. The key to achieving this balance is honest spring rate selection based on your actual constant load—over-springing creates a harsh, bouncy ride on-road, while under-springing causes sagging and poor handling. Paired with quality shock absorbers, these springs deliver the refined on-road manners expected from modern 4WD suspension while maintaining the durability needed for Australian conditions.
Proper Heavy Duty Springs for Serious Touring
After running these Toughdog rear coils through the Simpson Desert and across to the Canning, they've handled everything I've thrown at them with a full load of recovery gear, water, and camping kit. The ride quality is noticeably better than stock, especially when loaded up, and they've maintained their height after thousands of corrugated kilometres. Fitment was spot-on for my '05 TJ and they're holding up brilliantly in the dust and heat.(5)
Perfect upgrade for our loaded family camper
These Toughdog rear coils have completely transformed how our TJ handles when we're loaded up with the family and all our camping gear for weekend trips. The difference is night and day - no more sagging in the rear and the ride quality on corrugated dirt roads is actually better than the factory springs were when empty. Installation was straightforward and they've held up perfectly through several months of Cape York and High Country touring.(5)
Proper upgrade for a work rig
Been running these Toughdog rear coils for about six months now with tools and materials in the tray daily, and they've completely sorted out the sag I had with the stock springs. The ride is heaps better even when loaded up, and they handled a recent trip down some pretty rough farm tracks without any dramas. Well worth the coin if you're actually using your TJ for work.(5)
Solid Springs for Heavy Touring Loads
Been running these Toughdog rear coils on my TJ through the Simpson Desert and Cape York, and they've handled everything I've thrown at them. The ride quality is noticeably better than stock, even with a full touring setup including dual batteries, fridge, and recovery gear. Fitment was spot-on and they've maintained their height perfectly after 18 months of hard work.(5)
Perfect Upgrade for Our Loaded Family Camper
Been running these Toughdog rear coils for about six months now with the Wrangler fully loaded up for weekend camping trips with the kids. The difference in how the back end sits under load is night and day compared to the factory springs - no more sagging when we've got the fridge, swags, and all the gear packed in. Ride quality is surprisingly good too, even when empty around town during the week. Well worth the investment for anyone doing regular touring.(5)
