OEM vs Aftermarket Tub Centering Spring Kit for Whirlpool/Maytag: Honest Comparison (W10400895)

Your Whirlpool WTW4900AW0 is walking across the laundry room floor during spin cycle. You've watched it shimmy six inches toward the dryer, and you're weighing your options: the OEM Whirlpool spring kit at $45–$60, or this aftermarket 2-pack at $10.99. Let's break down what you're actually getting with each option.

Quick Answer

The aftermarket W10400895 spring kit delivers identical performance at one-fifth the price. Unless you're filing a warranty claim on a brand-new washer, there's no functional reason to pay OEM pricing for these simple metal springs. Both solve the same shaking and spinning issues — the OEM version just comes in fancier packaging.

Side-by-Side Comparison

When OEM Makes Sense

There are exactly three scenarios where paying 5x more for the OEM version is justified:

Your washer is under manufacturer warranty. If your Maytag MVWC400XW4 is less than a year old, using OEM parts keeps your warranty intact. Some manufacturers will void coverage if they detect aftermarket parts during service calls.

You're a commercial laundry service. High-volume operations sometimes have contracts requiring OEM parts for insurance or franchise compliance. If you're washing 40 loads a day in a laundromat, check your policy first.

You need the original packaging for resale. Flipping a washer for retail? Some buyers expect to see OEM part boxes. It's pure perception, but it can affect resale value by $20–$30.

That's it. For the 97% of homeowners fixing their own Whirlpool WTW4910XQ1 or Amana NTW4630YQ0, the OEM premium buys you nothing but a branded label.

When Aftermarket Wins

The W10400895 is a centering spring — two coiled pieces of metal that keep your wash tub aligned during spin. There's no circuit board here, no complex mechanics, just springs doing spring things. The aftermarket version is manufactured to the exact OEM specifications because those specs are publicly available.

Here's what makes the aftermarket option smarter for most repairs:

You get a spare. This 2-pack means you have a backup when one of the springs eventually wears out again in 5–7 years. The OEM version is sold individually, so you'd pay $45 twice to have the same coverage.

Faster delivery. Authorized Whirlpool dealers don't stock every part. You'll wait 3–7 days while they order from the warehouse. Aftermarket ships same-day, arrives in 2–3 days — your washer isn't shaking across the floor that whole week.

Better warranty. One year full replacement versus 90 days parts-only. If this spring fails (rare, but it happens), you're not arguing with a parts department about whether the failure was "installation error."

The metal is identical. The spring rate is identical. The mounting holes line up perfectly on your WTW4800XQ2 or 7MWTW1706YM0. You're solving the exact same shaking and spinning issues for $10.99 that OEM would charge $50+ to fix.

Our Verdict

Buy the aftermarket W10400895 kit unless your washer is under active manufacturer warranty. You're getting two springs for the price of one OEM spring, faster shipping, and a longer warranty. These are commodity parts — there's no proprietary technology here justifying a 450% markup. Save the $40 for your next repair, because if your springs are failing, your shock absorbers probably aren't far behind.

Frequently Asked Questions

Will aftermarket springs void my Whirlpool warranty?

Only if the washer is currently under manufacturer warranty and you file a claim. Whirlpool can't void an expired warranty, so once you're past the first year, use whatever parts make economic sense. If you're still covered, stick with OEM for major repairs, but minor wear items like springs rarely trigger warranty claims anyway.

How do I know if my centering springs are causing the shaking?

Open the cabinet and manually lift the wash tub about an inch. If it doesn't spring back to center smoothly, or if you see one side sagging lower than the other, the centering springs (W10400895) are worn. Also check for rust or visible gaps in the spring coils — that's a definite replacement signal on models like the NTW4601XQ0.

Can I install just one spring, or do I need to replace both?

Replace both even if only one looks damaged. Springs wear at roughly the same rate, so if one failed, the other is close behind. Installing just one means you'll have mismatched tension, which creates the same shaking problem you're trying to fix. The 2-pack aftermarket kit makes this easy — use both now, no second-guessing.
