9 Best Cuisinart Blender Replacement Parts 2026

If your Cuisinart blender has lost its punch or refuses to spin altogether, the SPB7-20TXN clutch replacement could be the lifesaving fix you didn’t know you needed. This small but mission-critical component—the motor drive clutch—transfers power from the base to the blade assembly, and when it wears out or cracks, your blender becomes a paperweight. Designed as a direct-fit spare, this durable plastic coupler restores full torque transmission across a wide range of models, solving the all-too-common issue of slipping gears and stalled blending without demanding a costly full-unit replacement.

In real-world testing, replacing the clutch with this 2-pack SPB7-20TXN unit took under five minutes and revived a sluggish CB-9 that had struggled with ice and frozen fruit for months. The high-impact polymer construction holds up well under stress, maintaining grip even during prolonged high-speed cycles. It’s compatible with nearly every 7-speed Cuisinart model from the CB and BFP series, including older workhorses like the CBT-500. However, if your jar or blade assembly is also leaking or corroded, this won’t fix those issues—this part only addresses drive failure, not sealing or blending performance.

Positioned as the best spare clutch set, this product stands out for offering two units at a budget-friendly cost, making it ideal for owners who want backup protection against future breakdowns. Compared to replacing the entire motor base or upgrading to a newer model, this clutch offers maximum value for minimal investment. It’s the kind of no-nonsense, precision-targeted fix that turns a dead appliance back into a daily kitchen warrior—especially when contrasted with full jar or blade replacements that cost significantly more for less critical repairs.

When your Cuisinart blender jar cracks or the base seal starts leaking, the LMEI 6-cup glass jar replacement delivers a complete, ready-to-use solution that feels like a factory refresh. This isn’t just a jar—it’s a fully assembled unit with a stainless steel blade, black locking collar, and lid, all pre-mounted and tested for seamless integration. For users tired of piecing together gaskets and blades, this all-in-one upgrade eliminates guesswork and reassembly errors, making it the most practical full-jar fix in the lineup.

During testing, the thick tempered glass handled heavy smoothie cycles and hot soup blending without stress marks or clouding. The SPB-7CH-LR collar locked securely into a decade-old CB-7 base, creating a leak-proof seal that outperformed the original after years of wear. At 6 cups, it’s ideal for small families or meal prep, though larger batches will require multiple runs. The only caveat? The jar’s height and base footprint match original specs exactly, so if your storage space is tight, verify clearance before ordering.

As the best full jar replacement, the LMEI kit outshines individual part swaps by restoring like-new performance in one go. Compared to buying a blade, gasket, and jar separately—which often exceeds $40—this package offers better value and reliability. It’s the top pick for users who want maximum convenience and long-term durability, especially when weighed against cheaper plastic jars that cloud or crack over time.

For budget-conscious users facing dull blades or minor leaks, the SPB-456-2 blade assembly offers a no-frills, high-impact fix that revitalizes blending performance at a fraction of the cost. This stainless steel cutting unit comes paired with two durable rubber gaskets, ensuring a tight seal between jar and blade—critical for preventing the annoying post-blend drips that plague aging Cuisinart models. It’s the most economical way to restore sharp, efficient chopping without replacing the entire jar.

In real use, the dual-bevel blade design pulverized ice, onions, and leafy greens with ease, matching the output of the original factory blade. The 2.7-inch diameter fits snugly in standard 6-cup jars, and the included gaskets provide redundancy for future maintenance. However, the plastic hub that connects to the clutch shows signs of wear faster than metal alternatives, and long-term durability under daily use remains questionable. Still, for occasional blenders or secondary units, it’s more than sufficient.

Positioned as the best budget-friendly option, this assembly undercuts premium replacements while covering the essentials. Compared to the Aooba or LMEI versions, it lacks packaging flair or extra gaskets but delivers core functionality at rock-bottom pricing. It’s ideal for users who need a quick, reliable blade swap and aren’t planning long-term upgrades—especially when contrasted with multi-part kits that cost twice as much for similar performance.

When leak prevention is a top priority, this 3-gasket blade assembly stands out as the most prepared replacement in the lineup. The inclusion of three high-grade silicone seals means you’re not just fixing today’s drip—you’re stocked for tomorrow’s maintenance too. Designed as a direct match for the SPB-456-2B, this stainless steel blade slices through frozen fruit and fibrous vegetables with authority, while the dishwasher-safe build ensures long-term hygiene and convenience.

In testing, the extra gaskets proved invaluable for users with multiple Cuisinart units or those who blend daily. The 2.71-inch blade seated perfectly in a BFP-703 jar, and the silicone seals compressed evenly, eliminating wobble and leakage. Unlike cheaper rubber rings that harden over time, these maintained flexibility after repeated heat cycles. The only downside? The lack of a collar or drive coupler means this won’t help if your motor isn’t engaging—this is strictly a blade-and-seal solution.

As the best with extra gaskets, this kit outperforms single-gasket models by offering long-term maintenance value. Compared to the B07QZQLMHT version, it adds critical redundancy at nearly the same price. It’s perfect for frequent blenders or multi-unit households who want to avoid repeated orders—and a smarter buy than purchasing gaskets separately, which often cost more in the long run.

Aooba’s blender cutting assembly strikes a sweet balance between price and quality, earning its title as the best affordable quality option for Cuisinart owners. The stainless steel blade is precision-formed to mimic OEM geometry, delivering consistent vortex action for smooth purees and emulsions. Paired with a BPA-free silicone gasket, it creates a tight, durable seal that resists warping—even after repeated exposure to hot soups and dishwashers.

Real-world testing revealed excellent blending efficiency, with no wobble or misalignment when locked into a CB-8 base. The black finish hides wear better than silver alternatives, and the single-gasket design is simple to replace when needed. While it doesn’t include extras like multiple seals or a coupler, the build quality exceeds its price point, outlasting several cheaper clones. It’s not the most feature-rich, but it’s the most reliable mid-tier choice for users who want durability without overpaying.

Compared to the SPB-456-2 model, Aooba’s version offers better materials and confidence in fit, while avoiding the premium cost of full jar replacements. It’s the go-to for users who value consistent performance and food safety—especially those blending baby food or nut butters where contamination risks matter. For a single, high-quality blade swap, this is the smartest middle-ground buy.

Few parts cause more frustration than a leaky blender seal, and the 3-pack gasket set from this brand is the ultimate preventive fix for Cuisinart owners. These food-grade rubber O-rings sit between the blade and jar base, forming a watertight barrier that stops drips before they start. When your current gasket has hardened, cracked, or lost elasticity, replacing it with one of these supple, high-tensile rings restores confidence in every pour.

In practice, the three included gaskets provide enough spares for 1–2 years of regular use, depending on cleaning frequency. The premium rubber compound resists deformation and heat degradation, outperforming OEM seals in longevity tests. Installation is foolproof—just press into the blade housing—and they work flawlessly with SPB-7, CB9, and BFP-703 models. Just note: not for compact mini blenders, only full-size units with dial controls.

As the best value multi-pack, this set beats buying single gaskets repeatedly. Compared to kits that bundle gaskets with blades, it focuses purely on sealing performance at the lowest per-unit cost. It’s ideal for households with multiple blenders or users who hate running out of critical spares. When contrasted with full assemblies, it offers targeted, cost-efficient maintenance—especially since a $6 gasket can save you from a $50+ jar replacement.

The B08ZJ5XMLJ blade assembly earns its title as the best standard replacement by delivering exactly what most users need—a reliable, no-surprises upgrade that just works. With a stainless steel blade and two high-quality gaskets, it covers the core maintenance needs of 90% of Cuisinart blender owners. The 2.71-inch diameter ensures compatibility across SPB, CB, and BFP series, and the dishwasher-safe design supports hassle-free cleaning.

Testing confirmed strong blending performance, with no wobble or leakage when paired with a fresh gasket. The dual-gasket inclusion provides a spare for future use, striking a smarter balance than single-gasket models. While it doesn’t include a coupler or collar, it’s not meant to—this is a focused, purpose-built part for when the blade dulls or the seal fails. The build quality matches OEM standards, making it a trustworthy fix for daily drivers.

Compared to the B092QSX55V model, it offers identical specs but slightly better availability, making it a safer bet for immediate need. It’s the go-to standard choice for users who want proven compatibility and straightforward performance without extras. When weighed against pricier kits, it delivers core functionality with zero fluff—ideal for a single, dependable repair.

When your Cuisinart blender won’t spin and leaks fluid, this dual-component kit is the most comprehensive mechanical fix available—addressing both drive failure and blade wear in one package. The SPB-456-2B blade assembly pairs with the SPB7-20TXN motor clutch, tackling the two most common failure points: slipping power transfer and dull cutting. For users whose blenders have gone quiet or struggle to start, this combo is a true resurrection kit.

In real use, installing both parts restored a non-functional CB-7 to full high-speed operation, crushing ice within seconds. The metal blade with attached coupling ensures solid connection, while the rubber gasket prevents leaks at the jar base. The black stainless steel looks factory-fresh, and the entire setup takes under 10 minutes. However, it’s overkill if only one component is faulty—don’t buy this just for a blade swap.

As the best for motor clutch issues, this kit outshines single-part replacements by offering complete drivetrain recovery. Compared to buying blade and clutch separately, it’s cheaper and more convenient. It’s ideal for diy repairers and long-term owners who want to extend their blender’s life—especially when contrasted with full base replacements that cost 5x more. For total mechanical restoration, this is the smartest single purchase.
