Chevrolet Silverado ZR2 long-range tank upgrade — done right in Ballarat

We’ve just finished a neat factory-style long-range fuel tank install on a Chevrolet Silverado ZR2, swapping out the standard tank and adding 100+ litres of usable capacity. The owner tows and tours regularly; the brief was simple: fewer fuel stops, more time on the road.

Why owners go long-range

If you’re hauling a van, boat or horse float, range drops fast. A larger, purpose-built tank means you can run the Western Hwy, the Grampians loop or a High Country weekend without planning your day around bowsers. It’s also safer and tidier than juggling jerries.

What you’ll notice:

• Serious touring range for country kilometres and remote legs
• Less stress when towing—stick to your schedule, not the servo map
• Practical payload management—weight sits low and secure
• Better resale story—a quality, documented upgrade enthusiasts look for

How we install (the Eason’s way)

• Vehicle-specific, baffled tank with corrosion-resistant construction
• OEM-style mounts and shielding, clearances checked for off-road use
• Sender/gauge calibration so distance-to-empty stays believable
• Breather/EVAP routing to fill cleanly without fumes or splashback
• Lines, heat shields and filters inspected and renewed where needed
• Road-test and documentation added to your service history

We only pair upgrades with genuine-grade filters and lubricants at service time, so your new-car warranty is looked after and the driveline stays happy.

Questions we’re often asked

Will it affect warranty?

A correctly fitted, model-specific tank won’t void your warranty for unrelated items. We follow manufacturer-aligned procedures and record the work.

How much extra range?

Driving style and load vary, but an extra 100+ litres typically adds hundreds of kilometres—especially noticeable when towing.

What about weight/GVM?

Extra fuel is extra mass. We’ll talk through payload, towball download and tyre pressures so you’re set up properly.

Off-road ready?

Yes. The ZR2 is built for it. We protect the tank and check departure angles and under-body clearance before sign-off.

We’re known as Ballarat’s European car specialists, but our workshop is equally at home with American pickups and touring builds.
