Front springs — OEM specs and part numbers

Tags: #springs · #part-number · #counterfeit

OEM vs. Mazda wire-thickness mismatch: OEM front springs use 14mm wire thickness; Mazda alternative springs measure 12.5–12.75mm — a meaningful difference that can affect suspension geometry and ride characteristics. Some owners report the Mazda springs ride softer as a result. Consider the wire-thickness gap carefully before substituting ¹.

Original front spring dimensions (spec, March 2026): OEM FAW X80 front spring measurements — outer diameters D1=86mm, D2=112mm, D3=64mm, D4=92mm; free height H=384mm; wire pitch p=14mm; 10 coils. Many owners replace the OEM spring with the Sufix SZ1303 aftermarket spring (spring rate 13.5, height ~379mm), which sits slightly shorter but still raises the front end by roughly 20mm compared to stock once installed, because of its stiffer rate — this typically requires progressive spacers to bring the ride height back to normal for correct suspension geometry ²³⁴⁵⁶.

FAW front spring part numbers by engine/transmission: original FAW catalog part numbers differ by drivetrain: 5CA034011 for manual transmission, 5CA134011 for automatic and naturally-aspirated 2.0L, 5CA234011 for turbocharged versions — the differences account for engine-weight distribution. A separate community grouping: 1.8L MT and 2.0L MT reportedly share the same spring; 2.0L AT and 2.0L Diesel differ; 2.3L and 2.5L each have their own distinct spring ⁷⁸.

Stock spring coil count — 9 turns; genuine FAW springs are rare/counterfeited: stock FAW X80 front springs have 9 coil turns. Some owners tried 8-turn springs (for a lower stance) but found them unavailable after their initial purchase, so 9-turn remains the practical standard due to consistent availability. Caution: genuine FAW springs with the factory white-blue-green label are extremely rare; most springs sold as "FAW" are Chinese counterfeits with reproduced markings ^910111213.

Front spring/X40 incompatibility — do not cross-shop: the X80 and the smaller FAW X40 use different front suspension designs and are not spring-interchangeable — do not fit X40 front springs to an X80 expecting a match, even though aftermarket brands (e.g. Fobos) list springs for both models separately. (Wheel hubs/bolt pattern are also incompatible between X80 and X40 — see the wheel bolt pattern card.) ¹⁴¹⁵.

Front spring dimensions for custom manufacturing (Sept 2026): for owners considering a custom-made replacement spring rather than sourcing a cross-brand part, community-measured front spring dimensions are: rod (wire) diameter 13mm (measured on an MT-transmission car), lower coil diameter approximately 62/91mm, upper coil diameter approximately 87/116mm, and roughly 9.4 total coils; exact free height was not recorded. These dimensions can be handed to a custom spring manufacturer to produce a replacement matching the original specification ¹⁶.

Automatic vs manual. Victor states the automatic (AKPP / АКПП) X80 is about 35 kg heavier than the manual, so the front springs differ between the two versions ¹⁷.
