$75K Chevy ZR2: The Smart Build You Don't Need a 2500 For

Not everyone needs a 2500 HD — and this jet-black Chevy Silverado 1500 ZR2 is the proof. Over $75K spent, pre-registration GVM upgrade done, 35s legal in every state, and a 4.2 tonne tow rating baked in before it even hits the road. This is the smart 1500 build. We walk you through every single part of this interstate customer's ZR2 — from the BDS 3.5" suspension kit and KMC/IMS load-rated wheels wrapped in 35×12.5×18 Nitto Ridge Grapplers, to the 200Ah lithium underseat battery, 200W RedArc solar, ARB twin compressor, and the brand-new V2 roof rack. We even throw it on the scales before it leaves the workshop. What you'll see in this video ✅ Pre-registration GVM upgrade to 4.2t — what it means, what it costs you in payload (spoiler: 1,353 kg left) ✅ BDS 3.5" lift on a factory ZR2 — why it's only 1.5" taller than stock and why that matters for legality ✅ KMC/IMS load-rated wheels + 35×12.5×18 Nitto Ridge Grapplers — legal in every Australian state ✅ 200Ah custom lithium underseat battery + 2000W inverter + RedArc BCDC Alpha R — full RedVision app walkthrough ✅ V2 roof rack with 50" light bar, 200W solar, Starlink mount — same rack now on the GMSV HD show trucks ✅ ARB brushless twin compressor, electric side steps, airbags, Anderson plugs — the full touring kit ✅ Live weighbridge result: 2,847 kg kerb weight — and what that means against the 4.2t GVM ✅ 1500 vs 2500 HD — the honest answer on when the ZR2 is the right call and when to step up Build highlights ✅ Suspension: BDS 3.5" lift kit (net 1.5" above factory ZR2 ride height) ✅ Wheels: KMC/IMS — 1,270 kg+ load rated ✅ Tyres: 35×12.5×18 Nitto Ridge Grappler — 1,800 kg per tyre rating ✅ GVM: Pre-registration upgrade to 4.2t (factory ZR2 GVM: 3,300 kg) ✅ 12V/Power: 200Ah custom lithium, RedArc BCDC Alpha R charger, 2000W inverter, RedVision app ✅ Solar: 200W panel on V2 roof rack ✅ Compressor: ARB brushless twin compressor ✅ Roof rack: V2 stainless/aluminium combo — 50" light bar, Starlink mount, powder coat texture black ✅ Steps: Excel series electric side steps ✅ Connectivity: Starlink with Gorilla mount, Switch-Pro control panel ✅ Airbags: Rear airbags with Schrader valves (Air IQ upgrade available) ✅ ADAS: Full reprogram of all sensors and cameras post-build Safety & setup notes ✅ Pre-registration GVM upgrade is the only legal path to 35" tyres on a 1500 in every Australian state ✅ ZR2 tow rating is 4.2t max (LTZ can achieve 4.5t) — if you're towing at or near GVM, consider stepping to HD ✅ Payload after build: approx. 1,353 kg — account for ball weight, passengers, and gear ✅ ADAS sensors and cameras fully recalibrated post-fitment — critical after any suspension or bar modification ✅ No rooftop tent on cab — not load-rated; use a tub rack for that setup ✅ Airbags: manual inflation via Schrader valves standard; Air IQ app upgrade available Not sure if the 1500, 2500, or HD truck is right for your tow setup?
