Vaccitect Heavy-Duty Rear Shock for Yamaha G29 G-Series, Red, 14in with Coil Spring and Oil-Hydraulic Damper

Vaccitect's 14-inch heavy-duty rear shock with integrated coil spring replaces OEM JN4-F2210-00/JN3-F2210-00/JW2-F2210-10 and restores rear support and ride control on Yamaha G-series golf carts.

If your Yamaha G29, G22, G20, G19, G16, G14, G9 or G6 feels saggy at the back, bounces excessively, or transmits too much vibration when carrying passengers or cargo, this rear shock assembly is built to bring back stability. Designed as a bolt-on replacement for 1995–2016 Yamaha Drive and G-series gas and electric models, the Vaccitect unit pairs a heavy-duty 60CrSi coil spring with an oil-hydraulic damper to reduce bounce, dampen noise, and handle heavier loads without bottoming out.

How does this shock improve ride comfort and control?

The oil-hydraulic damping smooths impacts from potholes, speed bumps, gravel, and uneven terrain, while the reinforced coil spring provides consistent support under load. Together they reduce vibration and keep the cart level during turns and stops.

• Oil-damped piston reduces rebound and harsh jolts
• 60CrSi coil spring prevents rear sag under passenger or cargo weight
• Optimized valving for stable handling across common cart speeds

Will this unit fit my Yamaha model and replace OEM part numbers?

This shock is engineered to fit Yamaha Drive (G29) and G-series models from approximately 1995 through 2016, both gas and electric. It directly replaces several original equipment numbers for a straightforward swap.

• Fits: G29/Drive, G22, G20, G19, G16, G14, G9, G6 (gas & electric)
• Replaces OEM: JN4-F2210-00, JN3-F2210-00, JW1-F2210-10-00, JW2-F2210-10-00
• Extended assembled length: 14 inches for correct ride height and clearance

What construction features extend durability and reduce maintenance?

The Vaccitect shock uses a polished 45# steel piston rod with double chrome plating and a fine-ground finish to resist corrosion and cut friction. Sealing and oil management are optimized to limit leakage and prolong service life even in humid or coastal environments.

• 45# steel piston rod with double chrome plating for corrosion resistance
• Micro-polished, fine-ground surface to minimize wear and friction
• Robust seals and oil-hydraulic design to prevent leakage and extend lifespan

How easy is installation and what should I expect during replacement?

The unit ships pre-assembled with bolt-on coil springs to match Yamaha rear mounting points, making replacement straightforward with common hand tools. You can expect quicker reinstall times and immediate improvement in rear support and damping.

• Bolt-on pre-assembled coil spring design for fast swap-out
• Standard mounting eyelets align with Yamaha rear shock brackets
• Minimal adjustments needed—torque to manufacturer specs and test ride

Who is this for: Owners, fleet managers, and service technicians of Yamaha Drive (G29) and G-series golf carts who need a durable, heavy-duty rear shock that restores rear ride height and improves passenger comfort under load. It’s ideal for carts frequently carrying passengers, heavy cargo, or aftermarket accessories where rear sag, excessive bouncing, or premature wear have become issues. The Vaccitect shock is also suited for anyone seeking a corrosion-resistant, long-life replacement that installs quickly and performs reliably across varied park, course, and utility terrains.
