Rear springs from Mazda 6 — cross-fit reports

Tags: #springs · #mazda-6-compat · #price · #cross-compatibility

Rear spring — Mazda 6 GG universal-coil alternative: FAW X80 rear springs can be replaced with Mazda 6 GG (2002-2008 generation) universal coil springs as a cost-effective alternative to OEM, available in auto-parts markets from ~3,000 RUB (RU market, March 2025). Both types reportedly have 6 coils — verify fitment with the supplier before purchase ¹.

Suspension-upgrade weight mismatch and pneumatic conclusion (disputed): Mazda 6 GG suspension components (donor car ~1,250 kg) are considered inadequate for the heavier X80 (~1,600 kg — a 350 kg / 28% difference that stresses components not engineered for the load, accelerating spring, damper, and linkage wear) ²³. Mazda 6 GH components are stronger but physically too large for the X80's suspension geometry and do not fit. A pneumatic air-bag system added to the rear is reported to resolve load-dependent bounce/bounce-back and provide a rear lift, tested successfully over 2 years by one owner. A full aftermarket-upgrade service is available but expensive. Disagreement: it is debated whether GH-sourced suspension is a viable upgrade path versus the pneumatic solution; the community consensus leans toward the weight difference making GH parts too large to fit, favoring the pneumatic route instead ⁴⁵.

Rear spring — Mazda 6 GH fits, GG does not (fitment by generation): rear springs from the Mazda 6 GH generation (post-2007) fit and work on the X80; springs from the older Mazda 6 GG generation are reported as shorter and do not fit in this account. Some owners have sourced OEM Mazda springs this way as a lower-cost alternative. Conflict: this contradicts the separate report elsewhere on this card that Mazda 6 GG (2002-2008) universal-coil springs work as a cost-effective rear alternative ¹ — treat GG-generation rear-spring fitment as disputed and verify the specific spring/generation before buying ⁶.

Conflict — Mazda 6 GG wagon rear springs "obligatory" vs. GG "does not fit" reported elsewhere on this card: a separate report insists that if sourcing rear springs from a Mazda 6 GG, they must come from the wagon/estate body specifically (обязательно) — sedan and hatchback GG variants also physically fit but do not provide proper support. This account frames the whole X80 rear suspension architecture as fundamentally Mazda-6-GG-based ⁷. This is in tension with the separate GG-vs-GH conflict already documented above ¹⁶ — treat GG-generation body-style (wagon vs. sedan/hatchback) as an additional, unresolved variable when sourcing Mazda 6 GG rear springs, on top of the existing GG-vs-GH generation dispute.

Rear spring failure and sagging — Mazda 6 GY-generation cross-fit (March 2026): a further round of reports on rear springs sagging over time (requiring the проставки/spacer fix documented throughout this card) adds two more aftermarket cross-fit options: springs from the Mazda 6 GY platform (2002–2007), specifically Fobos part 56023, and Zekkert-brand reinforced springs. Conflict: as with other entries on this card, some owners in this thread report the original springs losing compression while others report satisfactory durability — likely depends on driving conditions and load ^8910111213.

Reinforced (усиленные) rear spring variant also exists from Mazda 6 GG universal: alongside the standard Mazda 6 GG-universal rear spring (too soft, see below), a reinforced (усиленные) variant is also sold for the same Mazda 6 GG-universal application and is reported to give upgraded (stiffer) suspension performance versus both stock X80 (13mm rod) and the standard-softness GG-universal spring — worth specifically asking for the reinforced version when sourcing ¹⁴.

Mazda 6 sedan rear springs (12.3mm) — one success, one strong warning (conflict): Mazda 6 sedan (GG, 2002+) rear springs (12.3mm wire vs. the X80's own 13mm) are sold on Ozon as a rear-spring option. Conflict: one owner reports installing them on a facelift car with no issues, "went in like stock" ¹⁵; a second, more experienced contributor warns that these are sedan springs, not suited to an SUV/wagon use case — the thinner wire will likely sag quickly, and cargo load in the trunk will compress them hard; he recommends looking at wagon (universal)-sourced Mazda 6 springs instead for the X80's SUV-type loading ¹⁶¹⁷.

Rear springs from Mazda 6 GG — confirmed native fit on a facelift car: a separate, simpler confirmation (independent of the wire/coil-spec debate above): Mazda 6 GG rear springs "went in like factory" on a facelift X80. For alignment reference after any spring swap, use the X80's own manual figures where available; Mazda CX-5 specs are an acceptable fallback if X80-specific data isn't at hand (see the wheel alignment card) ¹⁸¹⁹²⁰.

Rear spring dimensions and cross-brand debate — Mazda 6 sedan too soft, wagon/universal preferred: asked for rear spring dimensions, one owner reported that springs are a known weak point on this car — all owners eventually have them crack — and that he personally has struggled with rear springs since summer: SAT-brand Mazda 6 springs (bought new from Avtotrade) sagged and started bottoming out with just one rear passenger after only a couple of months of use — "completely dead springs." He was searching specifically for reinforced Mazda 6 wagon ("универсал") springs, but reports these are mostly only available at wrecking yards near Moscow, with limited availability near Irkutsk ²¹²²²³. Separately, he clarified that Mazda 6 sedan springs are too soft; he recommends wagon or Mazda CX-5 springs instead ²⁴. A specific part was linked: rear spring for Mazda 6 (GY) 2002–2007 wagon, cross-referenced for FAW Besturn X80 2014–2021, part ST119065R, via an Ozon listing — confirmed by the poster as a fitting option ("вот такие подходят") ²⁵²⁶.

Mazda 6 GY rear springs (ST119065R) — detailed install, cost, and stiffness trade-off (Aug 2026): a Mazda 6 GY (2002-2007) universal-wagon rear spring, part ST119065R, was fitted after a rear spring broke at 58,000 km, alongside new rear shocks, rear brake pads, front shocks, and a gearbox/engine oil change. Total parts cost 24,000 RUB (RU market, August 2026), labor 8,000 RUB. Result: rear end raised to a reasonable level and the ride is much softer than the cracked stock spring's harsh "bang-bang" over every speed bump. Conflict on stiffness: a separate owner who fitted the same ST119065R part (rod stated as 12.75mm, matching the Mazda 6 GG-universal spec) reports it sat just as low as the stock spring once installed, still striking the bump stops occasionally past 60,000 km; a third owner who instead fitted a 13.3mm-rod, 269mm spring (6 coils vs. the stock 6.5) got a full-tank height of 470mm but found the ride noticeably stiffer, reasoning that fewer coils makes for a slightly harder spring ^2728293031.

Rear springs — Standard Springs ST119065R gives near-stock comfort (Aug 2026): a further confirmation of the Standard Springs-brand ST119065R rear spring (same part number documented elsewhere on this card): installed with no spacers, ride comfort and handling were reported as close to the original spring's, with a measured wheel-center-to-fender-edge height of about 43cm. Suitable for normal driving with typical loads rather than heavy hauling ^3233343536.

Oct 2026 update — Mazda 6 parts for the rear, rod diameters and spacers. Asked whether the X80 rear suspension can be taken from a Mazda 6, Тимур answered "practically" (all of it) ³⁷ and Миша thinks everything fits ³⁸; no exceptions or part numbers were given.
