Dobinsons IMS monotube rear shock absorbers (part IMS59-50229) suit the Toyota Hilux N80 (2015 - 11/2025) leaf-sprung rear axle. Monotube construction with an internal floating piston separates oil and gas, so damping stays consistent under sustained load and heat where a twin tube damper would fade. Suits the factory rear height and Dobinsons raised leaf packs. Sold as a matched pair, in stock in Australia with fitment support from our team.

These shocks work with your existing or upgraded rear leaf springs — the shock's load-rated monotube damping fine-tunes ride height rather than load capacity, so spring selection still matters. Choose a heavier-rated rear leaf spring if you regularly carry a canopy, tray tool boxes, dual battery setup, water tank or fridge slide, and step up further again for constant towing near GVM. Common accessories that push spring selection up include steel trays, canopies, long-range fuel tanks, winches and draw systems fitted permanently to the rear.
Note: These are rear dampers for the leaf-sprung N80 rear axle. Rear ride height is set by the leaf spring pack, not by the damper — if you need more rear height or load capacity, see our Dobinsons rear leaf spring range.
Fitting is a bolt-on job for an experienced DIY installer with basic hand tools, though we recommend a qualified suspension fitter for correct torque and load-rated monotube damping setting. Wheel alignment is required after fitting to bring camber, caster and toe back within factory tolerance. Allow a 500km bed-in period for the shock bushes and dampers to settle before final alignment checks. If you're also updating geometry at ride height, look at our control arm upgrades to correct caster on a lifted Hilux N80.
Dobinsons has built shock absorbers and suspension components for Australian 4WDs and utes for decades, with IFP and MRA shock ranges developed and tested on local roads and tracks. Every Dobinsons shock is backed by a manufacturer warranty, and we stock this rear shock set locally for fast Australia-wide dispatch. Browse the full Dobinsons suspension range for matching front shocks, springs and control arms for your N80.
This rear shock set suits Hilux N80 owners carrying steady tray, canopy or towing weight who need adjustable rear height without swapping to a full lift kit. It's a solid fit for tradies running service bodies and tourers with a loaded drawer system, roof-top tent or long-range fuel and water. If you're chasing precise load-levelling under variable weight, also look at our airbag suspension options to run alongside your rear springs.
In stock in Australia and ready for fast dispatch, with our team on hand to confirm fitment for your specific N80 build. Browse our full lift kit range or get in touch if you need help matching springs and control arms to these rear shocks.

Yes, these Dobinsons IFP load-rated monotube damping Rear Shocks are built specifically for the Toyota Hilux N80 built from 2015 onward, covering Workmate, SR, SR5, Rugged, Rugged X and Rogue variants. They bolt to factory rear mounting points using the supplied bushes and hardware. If you're running a different Hilux series or an earlier N70 model, contact our team to confirm the correct shock part number.
These are height-adjustable rear shocks, not a raised spring kit, so lift comes from the shock's multi-position collar working with your rear leaf springs. The collar lets you set rear ride height across a range suited to standard height through to a lifted rear end. Actual lift achieved depends on the leaf spring rating fitted and the load carried, so pair these shocks with the correct rear leaf springs for your target height.
You get 2 x Dobinsons IFP load-rated monotube damping Rear Shock Absorbers with the load-rated monotube damping pre-fitted, mounting bushes and fitting hardware for the factory mounting points. Front shocks, coil springs, leaf springs and control arms are not included and are sold separately. See the Kit Includes list above for the full breakdown.
Yes, the monotube IFP design is well suited to towing use because it keeps oil and gas separated for more consistent damping as the shock heats up under sustained load. For regular towing near GVM, match these shocks with a heavier-rated rear leaf spring rather than relying on the shock alone to carry weight. Our team can help you select a leaf spring rating suited to your towball weight and payload.
These are rear shocks, so front control arms aren't directly affected by fitting them. If you're also lifting the front of your Hilux N80, upgraded control arms help correct caster and reduce CV angle at ride height. For a rear-only shock change like this, control arm upgrades aren't required.
Yes, a wheel alignment is required after fitting these rear shocks, particularly if the height collar setting changes your rear ride height. Alignment brings camber, caster and toe back within factory tolerance and reduces uneven tyre wear. We recommend checking alignment again after the 500km bed-in period once bushes have settled.
These shocks aren't sold with springs, so spring rate selection is separate and depends on your Hilux N80's constant load. Dobinsons offers multiple rear leaf spring ratings to suit light touring through to heavy canopy and towing setups. Our team can recommend a leaf spring rate to run alongside these rear shocks based on your accessories and towing weight.
Rear shock height adjustment alone can provide some extra clearance, but tyre fitment depends more on the front lift height, wheel offset and any body clearancing. Most N80 Hilux owners running up to a 2" front lift can fit a modest tyre size increase, but always check clearance against your specific wheel and tyre combination. Contact our team with your intended tyre size for a fitment check.
These Dobinsons IFP rear shocks are covered by the Dobinsons manufacturer warranty against defects in materials and workmanship. We handle warranty claims through our Australian-based team, so you're not dealing with an overseas supplier directly. Keep your proof of purchase and fitment date for any warranty claim.
Yes, the IFP monotube design is set up to keep a controlled, comfortable ride at standard load while still supporting the vehicle when carrying gear or towing. Many Hilux N80 owners run this shock set as their daily driver and touring setup without a harsh or unsettled ride. Selecting the right height collar position for your typical load helps keep the ride balanced day to day.
