Ming Diamond Outer Spring Shock Absorber – Tough Enough for the Bumpiest Roads, Built to Last

Product Overview

At Xuzhou Mingzuan Shock Absorbers Co., Ltd. – the folks behind Ming Diamond – we don’t just churn out parts. We build shock absorbers that solve real problems. Our best-selling outer spring shock absorber? It’s the result of years of listening to what drivers and manufacturers actually need: something that doesn’t quit when loaded down, stays smooth over potholes, and outlasts the cheap stuff.

Here’s the truth about most spring shock absorber options on the market: They either sag under heavy loads, rattle so bad you can’t hear yourself think, or wear out in 6 months. Ours? It hauls 800kg without breaking a sweat, glides over rough roads like they’re paved, and sticks around twice as long. That’s why factories building electric tricycle accessories and complete vehicles make it their first pick. Pair it with our Motor Bike Triple Clamps, and you’ve got a front-end setup that turns daily rides from a chore into something almost easy.

We’re not stuck in the past, either. Our team tweaks designs based on real-world feedback – whether it’s a delivery driver in Manila or a farmer in Kenya. Because a shock absorber that works great in one place should work great everywhere.

Technical Specifications

The Nuts and Bolts – What Makes It Work

Brand: Ming Diamond
Made In: Xuzhou, China – our factory’s been refining shock tech since 2010
Fire Wire Rod: Six-sided "boutique" design – no slipping, no wiggling, even when maxed out with cargo
Screw Holes: M8 size – fits the bolts most tricycle and motorcycle frames use (no hunting for special tools)
Aluminum Tube: 0.3cm thick walls – light enough to not drag down your ride, tough enough to take a beating
Shaft Hole: 1.5cm across – matches axle sizes on 90% of electric tricycles out there
Spring Material: High-strength alloy – 30% stronger than the cheap steel in budget shocks (we tested it: 1200MPa tensile strength)
Load Capacity: 150kg to 800kg – we ran a test with 600kg over 10,000km, and it didn’t flinch
Length Options: 25cm to 40cm standard – need something shorter or longer? Just ask. We’ll make it work.

What Makes This Shock Different

1. New-Gen Materials – Lasts Twice as Long as Cheap Shocks

We ditched the old spring steel everyone else uses. Our alloy? It’s a game-changer:

30% higher compressive strength – so it won’t bend when you’re hauling a full load of fruits to market
Super low friction – parts glide instead of grinding, which means they don’t wear out fast (we’re talking 50,000km+ of use)
Twice the lifespan of basic motorcycle shock absorber models – a repair shop in Lagos told us, “We used to swap shocks every 6 months. These? 14 months and still going strong.”

2. Built-In Hydraulics – No More “Thudding” Over Potholes

That little hydraulic unit isn’t just extra bulk – it’s why drivers love this shock:

No “bottoming out” – when you hit a big bump, it cushions the impact instead of slamming to a stop (saves your back and your cargo)
Quiet as can be – no loud “boing” noise when you hit a curb (your neighbors will stop glaring)
Works in all weather – from freezing winters in Istanbul to scorching summers in Jakarta, it stays consistent

How to Install & Keep It Running Smooth

Check the Fit First: Make sure your vehicle’s Motor Bike Triple Clamps or frame has M8 screw holes. If not, ask us about adapters.
Clean the Mounts: Scrub off dirt, rust, or old grease from where the shock attaches. Gunk makes it loose over time.
Tighten Just Right: Use a torque wrench to crank the M8 screws to 25-30 Nm. Too loose, and it wiggles; too tight, and you’ll strip the threads.
Test It Out: Take a 10-minute ride over bumps and potholes. It should feel smooth, no clunking or rattling.
Keep It Happy:
- Check monthly for oil leaks around the hydraulic unit (a little dampness is normal; puddles mean trouble)
- Wipe the spring and tube with a damp cloth every 3 months – dirt grinds away at the finish
- Re-tighten the screws every 6 months – vibrations loosen things up over time

Where This Shock Shines

1. Electric Delivery Tricycles

Perfect for hauling packages, food, or groceries in busy cities. The high load capacity means you can stack more, and the smooth ride keeps fragile stuff (like eggs or electronics) from breaking.

2. Motorcycle Fleets & Daily Rides

Whether it’s a fleet of delivery bikes or your personal ride, paired with Motor Bike Triple Clamps, it cuts down on rider fatigue. No more sore hands after a long day.

3. Rural & Farm Use

Unpaved roads? No problem. The hydraulic system soaks up ruts and rocks, so you can haul tools or crops without bouncing around.

4. Vehicle Factories

Easy to install on assembly lines for electric tricycle accessories and complete vehicles. Standard M8 holes mean no retooling – saves time and money.

What This Means for Your Bottom Line

Spend Less on Replacements: Twice the lifespan = half the cost over 3 years. A delivery company in Bangkok saved $800 in a year by switching.
Less Downtime: Fewer breakdowns mean more time on the road. One fleet manager told us, “We used to have 3 bikes in the shop weekly. Now? Maybe one a month.”
Happier Drivers: Smooth rides mean less fatigue. Drivers report staying on the job 2 hours longer when their shocks work right.
Fewer Damaged Goods: No more “bottoming out” means fragile cargo stays intact. A grocery delivery service cut damaged goods claims by 70%.
Works with What You’ve Got: Fits most tricycles and motorcycles – no need to buy new frames or Motor Bike Triple Clamps.

Certifications You Can Trust

ISO 9001:2015 – our factory follows strict quality checks, so every shock is as good as the last
CE Certified – meets European safety standards, so you can sell in EU markets without hassle
RoHS Compliant – no toxic stuff, which matters for both your customers and the planet
SGS Tested – third-party labs verified our claims (50,000km lifespan? It’s not just talk)

We’ll Make It Fit Your Needs

Need something a little different? We’ve got you:

Odd Sizes: Need a 18cm short shock or a 45cm long one? We can make it (minimum 100 units).
Spring Tension: Soft for light loads (like passenger tricycles) or stiff for heavy cargo (construction materials).
Color Matches: Want it to match your brand? We can powder-coat it (minimum 500 units).
Special Mounts: Not using M8 screws? We’ll adjust the holes to fit your bolts.

How We Build It – Quality Every Step

We start with raw alloy – every batch gets tested for strength before it even hits the factory floor.
Our machines shape the aluminum tube to 0.3cm thickness – no shortcuts, no thin spots.
The spring gets heat-treated – a 3-hour process that makes it strong but flexible (too hard, and it snaps; too soft, and it sags).
Hydraulic units are built and pressure-tested – we pump them up to 500psi to make sure they don’t leak.
Everything gets put together, then tested for 24 hours under load – we simulate 1,000km of riding to catch issues.
Our quality team checks every shock by hand – if it doesn’t meet our standards, it doesn’t ship.
We make 5,000 units a day – so even big orders ship fast (usually within a week).

What Our Customers Say

“We run 20 delivery tricycles in Manila. Swapping to Ming Diamond shocks cut our repair bills in half. The drivers love how smooth they are, even over the city’s worst potholes. And they fit right with our existing Motor Bike Triple Clamps – no extra work.”
– Carlos M., Fleet Manager

“As a tricycle manufacturer, we need parts that work right out of the box. These shocks integrate perfectly with our electric tricycle accessories line. Our customers notice the difference – complaints about rough rides dropped by 80%.”
– Nguyen T., Production Head, Vietnam

“I repair bikes in a rural area. Farmers here haul heavy loads on bad roads – they used to burn through shocks. These Ming Diamond ones? The first set I installed 18 months ago is still going strong. Worth every penny.”
– James K., Repair Shop Owner, Kenya
