If you own or restore one of these classic vans, this little code could save you hours of searching for the right suspension part.

In this guide, I’ll break down what 8043123644 means, what part it represents, why it matters, and how it compares to other options available for the VW T4. Along the way, I’ll also share some practical tips on installation, maintenance, and how to decide between OEM and aftermarket choices.

What Does 8043123644 Stand For?

The number 8043123644 is a technical catalog identifier tied to a VW T4 rear suspension spring. It’s not a phone number or scam, but a product listing reference used by suppliers and manufacturers.

Here are the essential details:

• Part Name: Rear spring for VW T4
• Vehicle Fitment: VW T4 vans (1991–2003)
• Manufacturer: Miles
• Product Code: DB43162
• Country of Origin: China

This spring is part of the T4’s suspension system and plays a crucial role in supporting the vehicle’s load and ensuring a smooth ride.

Why Rear Springs Matter in the VW T4

If you’ve ever driven a VW T4, you know how important its suspension is. These vans were designed for versatility—used as commercial vehicles, family campers, and even long-distance travel vans. Over time, the rear coil springs take on the brunt of heavy loads and uneven roads.

Key roles of the rear spring:

1. Load Support – Balances weight across the rear axle.
2. Ride Comfort – Absorbs road shocks and keeps the ride smooth.
3. Vehicle Stability – Maintains handling when cornering or braking.
4. Durability – Ensures the van can carry cargo, passengers, or camper conversions.

Without a reliable rear spring, your T4 may sag at the back, feel unstable, or ride uncomfortably.

8043123644 and Its Equivalent OEM Codes

While 8043123644 (Miles DB43162) is the catalog number from one manufacturer, VW’s OEM code for the standard T4 rear spring is 701-511-105/C. Many aftermarket companies design springs to match this original specification.

If you’re replacing a spring, you’ll often see cross-references between these numbers. Always double-check compatibility with your van’s model year, payload, and suspension setup.

Standard vs. Heavy-Duty Springs

One common question T4 owners ask is whether to go with a standard spring or upgrade to heavy-duty (HD). Let’s compare:

So, if you mainly use your T4 as a family van or light transporter, 8043123644’s standard spring should work perfectly. But if you’re hauling heavy equipment or have a camper conversion, consider heavy-duty options.

How to Identify If Your Spring Needs Replacing

Your T4 won’t always shout at you when a rear spring is worn out—it’s more subtle. Here’s what to watch for:

• Rear sagging when loaded
• Uneven tire wear on the back wheels
• Clunky noises from the suspension
• A rougher ride that feels unstable
• Visible damage like cracks, rust, or a broken coil

If you notice any of these signs, it’s time to check part numbers like 8043123644 and prepare for a replacement.

Installation and Maintenance Tips

Replacing a rear spring isn’t overly complicated if you’re handy with tools, but it does require safety precautions.

1. Jack the van securely – Use axle stands for stability.
2. Remove the old spring – Carefully release tension and take it out.
3. Check associated parts – Inspect shock absorbers, bushings, and mounts.
4. Install the new spring – Ensure it’s seated correctly in the top and bottom mounts.
5. Test drive – After installation, check ride height and handling.

Pro tip: Always replace springs in pairs (left and right) to maintain balance and even wear.

Maintenance is equally important. Keep the suspension clean, check for rust, and avoid overloading your T4 if you’re using standard springs.

OEM vs. Aftermarket: Which Should You Choose?

With a catalog number like 8043123644, you’re looking at an aftermarket option. That’s not a bad thing—many aftermarket parts perform just as well as OEM, sometimes at a fraction of the cost.

OEM Benefits:

• Guaranteed fit
• VW-tested durability

Aftermarket Benefits:

• Lower cost
• Wider availability
• Performance variations (HD, reinforced, etc.)

The Miles DB43162 spring, for instance, is a trusted aftermarket solution made in China but distributed widely across Europe.

Cost Expectations

Prices vary depending on the source, but here’s a rough idea:

• Standard OEM rear spring: $100–$150 each
• Aftermarket replacement (8043123644 / DB43162): $60–$100 each
• Heavy-duty versions: $120–$180 each

Buying in pairs often saves money, and some suppliers include a warranty on aftermarket springs.

A Quick Buyer’s Checklist

Before clicking “buy” on a spring like 8043123644, check:

• Compatibility – Matches your T4 model year and payload
• Supplier reputation – Avoid knock-offs or poor-quality steel
• Warranty – Some offer 12–24 months
• Return policy – Handy if the fit isn’t perfect
