Toughdog Foam Cell rear shock absorbers are purpose-valved for the Jeep Grand Cherokee WG/WJ (1999-2005) and are sold as a genuine fitting pair, not a generic universal shock. Foam cell technology floods the shock body with nitrogen-injected foam instead of a free gas bladder, cutting oil aeration and fade on corrugated roads and long tows. Each unit uses a twin-tube design with hard-chrome plated shafts for corrosion resistance, with valving tuned to suit factory-height or lightly raised coil springs. Backed by Toughdog's manufacturer warranty and dispatched from our Australian stock with fitment support from our team.

Choosing the right rear spring rate matters more than the shock itself when you're carrying constant weight. Consider a bullbar and winch up front, a canopy or drawer system, long-range fuel tank, or a permanently fitted tow bar and second battery — all of this shifts your loaded weight distribution. If you're regularly towing or carrying heavy accessories, pair these shocks with a raised or higher-rated coil spring rather than relying on damping alone to control sag.
Fitting rear shocks on the WG/WJ is a straightforward job for an experienced DIY mechanic with a basic tool kit and jack stands, though we recommend a qualified workshop if you're not confident working under a loaded vehicle. Wheel alignment is mandatory after any rear suspension work, even a like-for-like shock swap, to confirm camber and toe haven't shifted. Allow a 500km break-in period for the new dampers to settle before judging ride quality. If you're planning to raise ride height at the same time, pair this job with correctly matched control arm upgrades to keep rear axle geometry correct.
Toughdog has built its reputation on Australian-based suspension engineering, developing foam cell and gas-charged dampers specifically for local vehicle configurations and load patterns rather than importing a single global tune. Every shock in this pair is backed by a manufacturer's warranty against defects, and our team can confirm current warranty terms before you order. Tradespeople, tourers and daily commuters running a WG/WJ all use this same foam cell platform because it holds its damping characteristics under repeated load cycles — view the full Toughdog range to compare shock and spring combinations for your setup.
This pair suits WG/WJ owners replacing tired, leaking factory shocks who want a direct like-for-like upgrade rather than a full lift kit. It's a solid fit for tradies carrying tools and gear, weekend tourers hauling a camper trailer, and anyone towing regularly who notices rear-end wallow on the highway. If you're carrying variable loads — on some trips empty, on others fully loaded — it's worth also looking at airbag suspension to add adjustable load support without changing your ride height when unladen.
These Toughdog rear shocks are in stock in our Australian warehouse for fast dispatch, and our team can confirm fitment against your build plate before you order. Browse our full lift kit range if you're planning a staged suspension upgrade alongside these shocks.

Yes, this pair is specifically valved for the WG and WJ generation Grand Cherokee built from 1999 to 2005, covering 4.0L petrol, 4.7L V8 and 2.7L CRD diesel variants. These shocks are matched to the factory rear live axle mounting points, so no drilling or modification is needed on a standard vehicle. If your Grand Cherokee has already been modified with a different rear axle or non-standard springs, check with our team before ordering. We can confirm fitment against your build plate if you're unsure which generation you have.
This shock pair on its own doesn't add lift — it's designed to work at factory ride height or alongside a raised rear coil spring you fit separately. Shocks control the rate of compression and rebound; the spring is what actually sets ride height. If you're chasing a specific lift, such as a 1" or 2" rear raise, pair these shocks with Toughdog's raised coil spring options and confirm the combination with our team first.
You get two Toughdog Foam Cell rear shock absorbers, upper and lower mounting bushes, and retaining nuts and washers, plus fitting instructions. Coil springs, control arms and other suspension hardware are not included and are sold separately. This keeps the kit focused and lets you choose your own spring rate to suit your load.
Yes, the foam cell damping in these shocks is specifically aimed at reducing fade under sustained load, which is exactly what happens when you're towing a trailer or camper on a long trip. Reduced oil aeration means the damping stays more consistent over corrugated roads and long descents compared to a worn factory shock. For heavier constant tow loads, we'd also recommend reviewing your rear spring rate to suit the actual weight you're carrying.
Not for a straight shock replacement at factory ride height — the WG/WJ's factory control arms will work fine with this pair. If you later raise the rear beyond around 2" using raised springs, upgraded control arms help correct axle geometry and driveline angles at the new height. Our team can advise whether control arms are needed based on your final ride height.
Yes, we recommend a wheel alignment any time rear suspension components are removed and refitted, even for a like-for-like shock swap. Ride height and suspension geometry can shift slightly during the job, and toe and camber should be checked before you get back on the highway. This is standard practice regardless of which brand of shock you're installing.
Yes, these rear shocks are sold separately from springs so you can match a coil spring rate to your actual accessory and towing load rather than being locked into one option. Toughdog offers standard and raised coil spring options for the Grand Cherokee that pair with this shock — talk to our team about your typical loaded weight before choosing a rate.
This shock pair alone doesn't change ride height or wheel arch clearance, so it won't create room for larger tyres by itself. If you want to run a larger tyre, you'll need to pair these shocks with a raised coil spring to lift the rear and gain clearance, and check clearance at full lock and full compression. Our team can talk you through spring and tyre combinations that work together.
These Toughdog rear shocks are backed by a manufacturer's warranty against manufacturing defects. Contact our team before ordering and we'll confirm the current warranty period and terms in writing. Keep your proof of purchase and fitment date, as this is generally required for any warranty claim.
Yes, this shock pair is a direct replacement for tired factory dampers and is comfort-tuned for everyday commuting as well as weekend towing or touring. Because it maintains factory ride height, there's no change to your Grand Cherokee's on-road handling characteristics beyond firmer, more controlled damping. It's a straightforward upgrade for anyone whose rear shocks are leaking, bouncing, or feeling vague at highway speed.
