CHERY FQ4241735F36 SPACER
Product Specifications
| CHERY | FQ4241735F36 |
The SPACER is a precision-formed polyurethane, rubber, or aluminium alloy spacer ring fitted between the strut top mount assembly and the body mounting face — or between the coil spring upper seat and the top mount — in a MacPherson strut suspension that raises the strut assembly's effective mounting height by the spacer's thickness, increasing the vehicle's ride height at the fitted axle without modifying the strut itself or altering the suspension's designed travel geometry. The spacer transmits the full static and dynamic strut load between the top mount and the body mounting surface — including the vehicle's corner weight, spring preload, and the inertial loads from road impacts — and must therefore be engineered for the compressive strength and fatigue life appropriate to the application: polyurethane spacers provide a near-rigid load path at ride frequencies while offering slight compliance under impulse loads; aluminium spacers provide a completely rigid load path suitable for performance applications where suspension compliance must be minimised. By raising the strut's upper attachment point relative to the wheel, the spacer increases the distance between the wheel centre and the body, raising the vehicle's ride height and restoring suspension travel that has been reduced by spring fatigue or body lowering. This function makes the strut spacer particularly applicable to high-mileage vehicles where both springs have taken a permanent compression set reducing ride height by 10–30 mm, and to vehicles requiring increased ground clearance for specific operating conditions.
This unit — CHERY FQ4241735F36 — is manufactured to OEM-fit specifications: outer diameter and inner bore for the strut top mount bolt pattern and piston rod clearance, spacer height for the specified ride height increase, material compressive strength rating for the application's corner weight, upper and lower face flatness for correct load distribution across the top mount and body mounting surfaces, and surface treatment for corrosion resistance in the underbonnet environment are matched to the installation requirements. Supplied as a pair for one axle. Available wholesale from 0.36 USD, MOQ 1 pcs, production lead time 30-45 days.
Strut spacers installed to correct ride height reduction from spring fatigue address only the height symptom, not the underlying cause — a fatigued spring that has settled 20 mm has also lost a proportion of its spring rate, reducing the suspension's ability to control body roll and absorb road inputs; a spacer restores ride height but does not restore the spring's rate. The correct long-term repair for spring fatigue is spring replacement; spacers are appropriate as an economical interim measure or as a deliberate ride height adjustment on vehicles whose springs are confirmed serviceable but whose ride height has been reduced by previous lowering springs or body modifications. Always confirm the application's acceptability with reference to the vehicle's type approval and local roadworthiness regulations before specifying strut spacers for a customer vehicle.
- Use a coil spring compressor to relieve spring preload before removing the top mount nut — the strut assembly carries significant spring preload even at full droop; removing the top mount nut without spring compressors releases this energy suddenly; always fit two independent spring compressors symmetrically on opposite sides of the coil and confirm both are fully engaged before loosening the top nut by more than one turn.
- Clean the body mounting face and the top mount upper face thoroughly before fitting the spacer — debris, rust scale, or old sealant between the spacer and its contact faces creates uneven load distribution that concentrates stress in the spacer material and causes premature cracking; the spacer must seat uniformly against both faces across its full contact area to distribute the corner load correctly.
- Confirm the spacer's inner bore clears the top mount stud or piston rod without contact before tightening the top mount nuts — a spacer whose bore contacts the piston rod or stud transmits chassis vibration directly into the rod and imposes a bending moment on the piston rod that accelerates rod seal wear; the bore must provide a minimum 2 mm clearance to the piston rod at all suspension positions.
- Torque the top mount nuts to the OEM specification after fitting the spacer — the spacer is clamped between the top mount and the body face by the top mount nuts; undertightening allows the spacer to move under dynamic loads and produce a knocking noise from the top mount area; overtightening crushes polyurethane spacers beyond their elastic limit and reduces their effective height, partially negating the intended ride height correction.
- Perform a four-wheel alignment immediately after spacer installation — any ride height change, including the spacer's height addition, shifts the vehicle's camber and caster angles from their previous settings; a spacer that raises the front ride height by 20 mm will typically change front camber by 0.3–0.7 degrees depending on the suspension geometry; alignment must be confirmed within OEM specification after spacer installation before the vehicle is returned to service.
- Install the new SPACER (CHERY FQ4241735F36) on both sides of the axle simultaneously, torque all fasteners to specification, lower the vehicle to ride height, measure the wheel arch height to confirm the target ride height has been achieved, perform a four-wheel alignment, and verify no tyre-to-arch contact through the full suspension travel range before returning the vehicle to service.
| Part | Reason for Combined Replacement |
|---|---|
| Coil Spring OEM ref. varies by axle position | A spacer fitted to correct ride height reduction from spring fatigue addresses only the height symptom — the fatigued spring has also lost a proportion of its spring rate, reducing body roll control and bump absorption quality. If the ride height reduction was caused by spring settlement, replacing the spring simultaneously with the spacer is the complete repair; the spacer alone on a fatigued spring restores the standing height but leaves the rate deficiency unaddressed. Inspect the spring for height loss and surface cracks whenever the strut assembly is disassembled for spacer installation. |
| Strut Top Mount Bearing OEM ref. varies by strut application | The strut top mount bearing is fully accessible whenever the top mount nut is removed for spacer installation. A bearing that shows roughness when rotated by hand under spring load, or that produces a creaking noise during parking manoeuvres, should be replaced simultaneously with the spacer during the same spring compression operation — it is the most convenient time to address a worn bearing without scheduling a separate strut disassembly. |
| Dust Boot and Bump Stop Kit OEM ref. varies by strut application | With the strut disassembled for spacer installation, the dust boot and bump stop are fully accessible and should be inspected for cracking, compression set, and boot tears. A boot that has cracked or a bump stop that has compressed beyond its height specification should be replaced simultaneously with the spacer — the incremental parts and labour cost of addressing both during the same disassembly is significantly lower than scheduling a repeat strut disassembly for boot or bump stop replacement within a short interval. |
