jiuoici steering damper for Exmark Lazer Z 2-pack — 7in closed/10in extended, heavy-duty gas replacement

jiuoici’s upgraded steering damper replaces OEM 109-2339 / 103-4079 to reduce vibration and stabilize steering on Exmark Lazer Z and many Toro Z Master models.

Designed as a direct aftermarket replacement, this heavy-duty gas damper is built to restore smoother handling and reduce vibration transfer from the mower deck to the operator. It pairs upgraded internal components and tougher materials with the same mounting dimensions as the original part for a fast swap-out. Each order includes two dampers sized to match factory fit: 7" closed length, 10" extended, with 5/16" mounting holes.

Will this damper fit my Exmark Lazer Z model?

The jiuoici damper is engineered to match many Lazer Z part numbers and model families. Cross-reference the OEM numbers or your mower’s model code to confirm compatibility before ordering. If your machine lists one of the included OEM references or model codes, it will fit without modification.

• Direct replacement for OEM numbers such as 109-2339, 103-4079, 131-4132, and equivalents.
• Fits numerous Exmark Lazer Z series codes (LXS, LZ, LHP, LAS, LCT, LZD, LZDS families).
• Supplied as a 2-pack for left and right steering or front/rear use.

How does this upgraded design improve mower performance?

This damper uses a revised shock-absorbing arrangement and enhanced materials to blunt high-frequency vibration and reduce the shock transmitted through steering linkages. The result is steadier tracking, less component wear, and a more comfortable ride for the operator. Improved internal springs and seals help the unit last longer under heavy use.

• Upgraded shock components absorb and dissipate vibration energy more effectively.
• High-strength metal and reinforced plastics resist pressure and fatigue.
• Reduced vibration extends service life of steering and related parts.

Is installation difficult and what are the exact dimensions?

Installation is straightforward for most owners and service technicians; the damper uses the same hole spacing and eyelet size as the OEM part for a direct swap. Typical installation takes only a few minutes with basic hand tools. The product comes as a pair so you can replace both dampers at the same time for balanced performance.

• Closed length: 7 inches; extended length: 10 inches.
• Mounting hole diameter: 5/16 inch on each end.
• Supplied as a 2-pack for front and rear or left and right positions.

How durable is the jiuoici damper under regular use?

Materials and internal components were upgraded to withstand repeated compression cycles and exposure to workshop conditions. jiuoici reports extensive testing and longer operational life than earlier designs, so the damper holds up under typical lawn tractor loads. Regular inspection and correct mounting will maximize lifespan.

• Reinforced metal and improved plastic components reduce cracking and deformation.
• Seals and cushioning elements resist oil loss and wear.
• Tested for thousands of cycles to ensure consistent damping action.

Who is this for: This steering damper is intended for owners, fleet managers, and service shops that maintain Exmark Lazer Z and compatible Toro Z Master mowers looking to replace worn dampers with a robust aftermarket option. It’s ideal for users who need a direct-fit replacement to restore steering stability, reduce operator fatigue from vibration, and limit wear on steering components. If you need an OEM form-and-fit damper that installs quickly and uses improved materials for longer life, the jiuoici upgraded 109-2339 / 103-4079 damper is built for that purpose.
