🔹 Step-by-Step Installation Guide
This kit is designed for easy assembly by experienced fabricators. Follow these steps for a secure and professional installation:
🔧 Preparation:
1️⃣ Review images for reference on mount positioning
2️⃣ Remove unused body components for clearance
3️⃣ Clean paint from the chassis in all mounting areas
🔧 Mounting the Main Roll Bar & Front Section:
4️⃣ Drill a 45-50mm hole under each mount for the main hoop legs to drop into the chassis rail
5️⃣ Tack weld the mounting plates in place
6️⃣ Position the Main Roll Bar (MRB) and tack weld the base
7️⃣ Fit and tack weld the A-Bars (LAB/RAB) & Lower Door Bars (LLD/RLD)
8️⃣ Secure the Front Roof Bar (RFB) and door bars to confirm proper alignment
🔧 Roof & Rear Assembly:
9️⃣ Install and tack weld the Roof Diagonals & Centre X Bracing
🔟 Align the Rear Stays (RB/LB) using the positioning marks, then tack them in place
1️⃣1️⃣ Fit and tack weld all remaining components
🔧 Final Welding & Completion:
1️⃣2️⃣ Weld all visible joints, but do not weld the mounts or feet yet
1️⃣3️⃣ Break the mounts off the body and remove the cage
1️⃣4️⃣ Fully weld all hidden joints for maximum strength
1️⃣5️⃣ Reinstall the cage, secure the mounts, and weld all final connections
