Choosing the right rear spring rate comes down to what you're carrying day-to-day, not what you carry occasionally. A TJ fitted with a rear drawer system, long-range fuel tank, dual-battery tray, roof-top tent or a tow bar with recovery gear needs a firmer rate than a lightly accessorised weekend tourer. Common accessories that affect spring selection include steel rear bars, water tanks, camping gear stored permanently in the tub, and caravan or trailer tow-ball weight.
Fitting this pair is a straightforward job for an experienced DIY installer with a spring compressor, though we recommend a qualified 4WD suspension workshop for the rear axle work. Wheel alignment is mandatory after fitting, as ride height changes affect camber and caster on the TJ's live axle. Allow roughly 500km of driving for the springs to settle before a final alignment check. If you're upgrading spring rate and ride height together, it's worth reviewing control arm upgrades to keep pinion angle and axle geometry correct.
Toughdog has supplied 4WD suspension components to the Australian market for decades, with spring and shock development carried out for local road and touring conditions. Every coil spring is backed by a manufacturer warranty, giving TJ owners confidence in the rate they select for their build. Tourers and tradespeople running TJ Wranglers with permanent rear loads rely on the Toughdog range for consistent ride height - view the full Toughdog range for matching shocks and front springs.
This pair suits TJ Wrangler owners who carry rear drawers, camping gear, dual batteries or fuel tanks on a regular basis and need the rear end to sit level rather than sag. It also suits tradespeople using their TJ to carry tools and equipment daily. If your load varies significantly from trip to trip, it's worth comparing this fixed-rate spring against airbag suspension for adjustable load support.
This Toughdog rear coil spring pair for the Jeep TJ Wrangler is in stock in Australia and dispatched quickly, with our team on hand to help confirm the right spring rate for your accessory load.

Yes, this pair of Toughdog rear coil springs is built specifically for the Jeep TJ Wrangler rear axle, covering model years 1996 to 2006. It's a direct bolt-in replacement for the factory rear coil springs using the existing upper and lower mounts. If you're running a modified TJ or a non-standard rear axle, contact our team to confirm your setup before ordering. We can also help you cross-check fitment through our TJ Wrangler parts finder.
This pair is designed primarily to restore or increase rear load capacity rather than deliver a set lift figure. Ride height once fitted depends on the constant-load spring rate you select, since a firmer rate under a lighter load will sit slightly higher than a soft rate under a heavy load. If you need a specific ride height for tyre clearance or a matched front-and-rear set-up, our fitment team can talk you through the right rate for your accessories.
You receive 2 x Toughdog heavy-duty rear coil springs as a matched pair, sold at your selected constant-load spring rate. Fitment reuses your factory upper and lower spring mounts and isolators, so no brackets or hardware kits are included. Shock absorbers, control arms and U-bolts are sold separately and can be sourced through our shocks and control arm ranges if needed.
Yes, selecting a firmer constant-load spring rate in this range is a common upgrade for TJ owners towing a trailer or camper with tow-ball weight on the rear axle. The correct rate reduces rear sag under tow-ball load and keeps the vehicle sitting level. Tell our team your typical tow-ball weight and we'll help match the spring rate accordingly.
Control arm upgrades aren't compulsory with a spring-only change, but they're worth considering if ride height changes noticeably or if you're also running a lift kit. Correct control arm geometry helps maintain pinion angle and reduces driveline vibration at a raised height. See our control arm range if you're planning a bigger suspension upgrade alongside these springs.
Yes, a wheel alignment is required after fitting new rear coil springs, as any change in ride height affects camber and caster on the TJ's live axle front and rear. We recommend booking an alignment once the springs have settled, typically after around 500km of driving. Skipping alignment can lead to uneven tyre wear and inconsistent steering feel.
Yes, this rear coil spring pair is available in multiple constant-load spring rate options to suit different accessory loads. Lighter setups with minimal rear gear suit a softer rate, while drawers, dual batteries, water tanks or tow-ball weight suit a firmer rate. Our team can recommend the right rate based on what you actually carry, rather than a generic guess.
Any change in tyre clearance depends on the ride height achieved with your selected spring rate, plus your current wheel offset and tyre size. Because this product is a load-matched spring rather than a fixed lift height, we recommend checking your intended tyre size with our fitment team before ordering. This avoids surprises with rubbing on guards or suspension components.
This Toughdog rear coil spring pair is covered by the Toughdog manufacturer warranty against manufacturing defects. Keep your proof of purchase from 4WD Suspension Australia for any warranty claim. Our Australian-based team can assist directly with warranty support if an issue arises.
Yes, when matched to the correct constant-load spring rate for what you actually carry, these rear coil springs maintain a comfortable, factory-style ride for daily driving. Choosing too firm a rate for a lightly loaded TJ can make the ride feel harsher than necessary, so it pays to be honest about your typical load when selecting a rate. Our team can help balance daily comfort against your touring or towing needs.
