Stage 3 Chevrolet Silverado 1500 LTZ ZR2 GVM 3850 Upgrade PRE
- GVM Increase: 3850kg (approx. 1272kg payload). GCM Increase 8050 KG ZR2 or 8350 LTZ
- Key Features: Premium Fox 2.5 DSC (Dual Speed Compression) adjustable shocks.
- Best For: Heavy-duty touring. If you have a bull bar, and a heavy tow ball weight from a large caravan, this is your sweet spot without having to upgrade your wheel and tyre package.
- Benefit: The DSC adjustability allows you to "dial in" your ride—stiffen it for the highway and soften it for the tracks at the turn of a knob. Fox’s premium shocks setup for the Chevy Silverado 1500.

Upgraded Fox & BDS suspension
You bought a massive American truck, so why insult it with wimpy suspension? Slap some heavy-duty American components under that beast, let freedom ring, and cue the bald eagles!
