A washer shock absorber kit replaces the friction dampers between the outer tub and the base of a front-load washer. They do not hold the tub up — springs do that. The dampers absorb the energy of a tub that is already moving, and when they wear out the machine bangs at the start and end of spin, shakes harder than it used to, and eventually walks. They are also the part most often bought when the real problem is the floor, the feet or the load.
Before you order anything, there is a two-minute check that costs nothing and resolves a large share of banging machines, and a push test that tells you whether the dampers are actually dead.

A walking machine is usually the floor, not the dampers
Here is something worth knowing before you spend: the manufacturers’ own troubleshooting for a banging, walking washer does not mention the suspension at all.
Whirlpool’s page on banging noises routes the whole problem through hoses knocking the cabinet, load distribution, the balance routine and levelling. Its levelling instruction is the most useful sentence on the subject: “The washer must be level, and all four washer feet must be in firm contact with the floor. Try to rock the washer diagonally, from corner to corner, with your hands. If the washer rocks, it needs to be leveled.”
Do that now, both diagonals. A machine rocking on three feet is trying to balance a load on a platform that is itself moving, and no new hardware fixes that. Maytag’s vibration guidance sets out what an unbalanced load produces — “noise, vibration, reduced spin speed, longer cycle times, and decreased washer performance” — and notes the machine “will try to self-correct by refilling the washer and gently rotating back and forth”. The rocking you hear before spin is that routine, not a fault.
Two more free checks. Move anything leaning on the cabinet: Whirlpool notes that “brooms, dustpans, dryer racks, or hangers can make rattling noises if they are leaning against the washer”. And if the machine is new, check the shipping bolts came out — a tub still bolted to the frame will shake a house.
Our how to level a washing machine page has the method, and washing machine walks during spin works through the floor itself, which on a suspended timber floor is often the real answer.
Where a washer shock absorber kit sits, and what is in the box
The suspension on a front-loader is two systems doing two jobs, and people conflate them.
Springs hang the outer tub from the top of the cabinet, carrying the weight and setting the resting position.
Dampers connect the bottom of the tub to the base at an angle, usually two and sometimes four. They are friction units — a piston dragging inside a sleeve — converting movement into heat, which is why they fade gradually rather than failing on a particular Tuesday.
What arrives in a “kit” varies more than it should. Some listings are a single damper, some a matched front pair, some four, and some commercial kits run to eight pieces with pins, bushings and locking nuts. Read the quantity before ordering — it is printed on every listing and it is the commonest source of disappointment here.
Top-loaders are a different arrangement again: four damped suspension rods from the corners rather than dampers at the base. Not interchangeable with anything on this page, and covered on washer suspension rods.
The push test, and what a dead damper feels like
With the machine unplugged, take the lower front panel off so you can see where the dampers meet the base.
Push the tub down and let go. Grip the drum through the door opening, push firmly down, release. A healthy damper resists and lets the tub return slowly with no bounce. A dead one lets it drop easily and spring back, often twice. The difference is obvious once you have felt both.
Look at each damper body. Oil on the outside, a cracked mount, a sheared pin or one hanging loose at an end is a visual answer, and you can stop testing.
Check the counterweights before you conclude. A loose counterweight bolt impersonates a dead damper, and Whirlpool documents a normal clunk too: “There will be a clunk noise as the drive system shifts from agitation mode to spin mode or vice versa. These sounds are part of the normal washer operation.”
One thing you will not find anywhere, and it matters: no manufacturer publishes a service life for washer dampers. The “five to seven years” figures circulating online come from pages selling the parts, with no test or method named. Judge yours by the push test, not by the calendar.
Count them, measure them, and know rods from shocks
Four things decide whether the kit you order fits, and none of them is the brand on the front.
The model number. On a front-loader the serial plate sits around the door frame, often behind the boot, or on the back panel. Photograph it rather than copying it out.
The part number on the damper itself. Stamped or labelled on the body, and this is the authority. The chains here are short: Samsung’s DC66-00470C replaces DC66-00650A, and Frigidaire’s 5304491701 replaces 137040900 and 7137040900.
The count. Two or four. Listings are sold both ways, and a two-pack for a four-damper machine means a half-finished job and a second order.
The mounting. Snap pins, clevis pins with clips, or bolts, and the style varies within a brand. If the kit has no pins, reuse yours only if they are undamaged — a cracked pin lets go under load.
And the distinction that trips people: a suspension rod is not a shock absorber. Rods are the long struts in the corners of a top-loader; dampers are the short angled struts at the base of a front-loader. Listings use the words interchangeably and the parts never substitute for each other.
Why they are sold in sets and why that is not upselling
If one damper has worn out, the others have done the same mileage under the same loads, and they are within months of each other.
The problem is geometry, not fairness. A stiff new damper opposite a worn one damps the tub asymmetrically and sends it along a path the balance system was never designed for. The machine can shake more after a single replacement, and the new part takes a disproportionate share of the load and wears early. Replace the full set your machine carries — two if it has two, four if it has four.
Four kits across the big washer platforms
Samsung DC66-00470C: the OEM damper, sold singly
Samsung’s genuine damper, superseding DC66-00650A, and the best-ranked Samsung option here.
Who it suits: Samsung front-load owners who have read DC66-00470C or DC66-00650A off the damper body.
What it does not do: this is one damper, not a kit. Count how many your machine has and order that many. It is the cleanest OEM part on this page and the easiest to under-order.
Frigidaire 5304491701: the dual-stage front kit
The Frigidaire and Electrolux front damper kit, carrying 5304491701 and replacing 137040900 and 7137040900. The same number appears under both badges, which share a corporate parent and a platform — useful when you are comparing listings that look like different products.
Who it suits: Frigidaire and Electrolux front-load owners whose dampers carry any of those three numbers.
What it does not do: it is the front kit, so check whether your machine also carries dampers at the rear before assuming the job is done.
Four-pack for Whirlpool, Maytag, Kenmore and Amana
The aftermarket set of four for the Whirlpool-group front-load platform, and the published model list is the reason to look at it: Whirlpool WFW70HEBW0, WFW9250WW01, WFW75HEFW0 and WFW9150WW00, Maytag MHWE450WJ02 and MHWE201YW00, Amana NFW7300WW00 and NFW7500VW00, Inglis IFW7300WW00, Kenmore 110.49222200.
Who it suits: owners of those machines who want all four changed at once, which is what this page has just argued for.
What it does not do: a generic part with a weak sales rank and no manufacturer warranty, and the listing invites you to ask about compatibility rather than publishing a definitive list. Check your model against those names first.
Whole Parts 472991310: the commercial eight-piece kit
The suspension and shock kit for commercial and on-premise machines, carrying 472991310 and 472991309 among others, supplied as eight pieces, with a model list running across the H7, EH, HS, W3 and W4 families.
Who it suits: anyone looking after a laundromat machine, an apartment-building washer or an on-premise unit on that platform. These are built to be rebuilt and the kit reflects it.
What it does not do: it is not for a domestic machine. The listing is admirably direct — it recommends a proper diagnosis first and warns against buying from the picture, which is advice worth taking on every product here.
FAQ
How do I know my shock absorbers are worn?
Unplug the machine, take the lower panel off, push the tub down through the door opening and release. A healthy damper resists and returns slowly; a worn one lets the tub drop and bounce. Then look for oil on the bodies, cracked mounts or a damper hanging loose at one end.
Do I have to replace all of them at once?
Yes, in practice. A new damper opposite a worn one damps the tub unevenly, which can make the shaking worse and wears the new part early. Replace the full set your machine carries.
How long do washer shock absorbers last?
No manufacturer publishes a figure, and the numbers circulating online come from pages selling the parts with no test behind them. Judge by the push test and by the behaviour of the machine, not by its age.
My machine still bangs after new dampers. What did I miss?
Almost certainly levelling or the floor. Rock the washer diagonally, corner to corner — if it moves, all four feet are not in firm contact and no suspension part fixes that. A suspended timber floor adds its own movement on top.
Are suspension rods and shock absorbers the same thing?
No. Rods hang from the corners of a top-loader; dampers sit at the base of a front-loader. Listings use the words loosely, the parts are not interchangeable, and ordering the wrong kind is common and avoidable.
Level it first, then replace the whole set
The first step takes two minutes. Rock the machine diagonally, corner to corner. If it moves, level it with all four feet firmly down and the locknuts tightened, then run a load before concluding anything. Move the brooms away from the cabinet, and if the washer is new, check the shipping bolts came out.
Then do the push test with the panel off, look for oil and cracked mounts, and count how many dampers you have. Read the number off the body: DC66-00470C for a Samsung, 5304491701 for a Frigidaire or Electrolux, and check your model against the published list for the Whirlpool-group four-pack. Commercial machines take the eight-piece kit; nothing domestic does.
Then replace all of them, not the one that failed the test. A balancing system with one new part and three old ones is still an unbalanced system — just a more expensive one.
