Made from imidized plastic, they compress slightly to match the separator plate seats for improved sealing and reduced seat wear. That combination helps maintain hydraulic integrity in the valve body without the repeated impact stress associated with hard metal balls.\u003c\/p\u003e\n\n\u003ch3\u003eHow do imidized-plastic check balls compare to steel check balls?\u003c\/h3\u003e\n\u003cp\u003eImidized-plastic check balls are engineered to be tough yet slightly compliant compared with steel. That small amount of give allows them to form a tighter seal in the valve body ball seats, while reducing pounding wear on the separator plate during high-cycle operation.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eConform to separator plate seats for improved sealing\u003c\/li\u003e\n  \u003cli\u003eReduce metal-on-metal impact that can create seat wear\u003c\/li\u003e\n  \u003cli\u003eLighter weight than steel, lowering dynamic forces\u003c\/li\u003e\n  \u003cli\u003eResistant to common transmission fluids and thermal cycles\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these fit my transmission valve body?\u003c\/h3\u003e\n\u003cp\u003eThese check balls are manufactured to a .250\" diameter standard that fits many GM valve bodies including 700R4, 4L60, 4L60E and 4L65E families.
