Tags: #control-arm · #part-number · #mazda-6-compat · #price

Arm numbers and cross-fits. The OEM number for the upper left front suspension arm is 5CA034250 (June 2025).¹ A December 2025 listing gives SUFIX C23034250 for the upper left front arm of the FAW B50 and X80, and the sellers say it also fits the Mazda 6 GG.² Other makers' listings for the X80: SH Auto Parts left SH31031 / right SH31030, and NK 5013231 (left) / 5013232 (right).³ A CTR CQ0253R front right upper arm (code 28736024) was shown on vseinstrumenti.ru at a last price of 4,437 RUB (RU market, May 2025), marked out of stock; X80 fitment is not stated in the image.⁴ The SUFIX SH-1365 upper left front arm appeared in a store screenshot at 1,720 RUB (4 in stock) and 1,950 RUB (2 and 6 in stock) (RU market, December 2025), posted by a Mazda 6 GG owner as a price comparison.⁵

Replacing the whole arm or only the bushings. One member replaced the whole arm and the silent blocks (сайлентблоки, rubber bushings) separately with Stellox parts and reports about 30,000 km without problems; he adds that the B50 arm is fine for the X80.⁶ For the front left upper arm (5CA034250) another member estimated two silent blocks at about 1,500 RUB plus about 1,000 RUB for pressing them in (RU market, March 2024), and noted that if the upper ball joint is worn, replacing the whole arm may make more sense.⁷ A commenter who replaced only the silent blocks later said the complete arm assembly would have been the better buy.⁸

Upper ball joint (шаровая опора). The upper front control-arm ball joint for the FAW Besturn X80 / X80 NEW has article C23034200-1, with analog C23034250; a kitzapchasti.ru listing showed it at 700 RUB (RU market, January 2026). Ball joints are sold either separately or with the arm, and the marketplaces only carry the assembly.⁹¹⁰¹¹ The B50 upper ball joint C23034250 was suggested as fitting the X80: one member said the joint is double-sided and fits either side, while another reported that the joint's code is registered as left-side and asked for the right-side code; fitment stays unconfirmed.¹²¹³¹⁴ An owner states that only the FAW ball joint fits and that it is hard to find; a linked Kitz Zapchasti listing for C23034200-1 is titled for the Besturn B50, not the X80.¹⁵⁸
