3. Safety Information
Automotive frame repair involves significant risks. Always prioritize safety. This product requires welding, which should only be performed by qualified individuals with appropriate safety gear and equipment.
- Wear appropriate Personal Protective Equipment (PPE), including welding helmet, gloves, long sleeves, and safety glasses.

- Disconnect the vehicle's battery before beginning any work.
- Have a fire extinguisher readily available.
- Secure the vehicle properly on jack stands or a lift before working underneath.
4. Installation Guide
Professional installation is strongly recommended due to the weld-on nature of this repair channel. No drilling is required for the primary installation, but minor adjustments may be necessary.
4.1 Pre-Installation Steps:
- Vehicle Preparation: Safely lift and secure the vehicle. Disconnect the battery.
- Assessment: Thoroughly inspect the existing frame for rust, damage, and structural integrity. Determine the exact area requiring repair.
- Rust Removal: Remove all rust, corrosion, and loose material from the area where the repair channel will be installed. This is critical for a strong weld. Use wire brushes, grinders, or rust converters as needed.
- Surface Preparation: Clean the mating surfaces of both the vehicle frame and the repair channel to ensure they are free of grease, oil, paint, and debris.
- Test Fit: Position the repair channel against the vehicle's frame to ensure proper alignment and fitment. Mark any areas that may require minor trimming or adjustment.

4.2 Welding Process:
- Positioning: Carefully position the repair channel onto the prepared section of the vehicle frame. Ensure it is flush and correctly aligned.
- Clamping: Use appropriate clamps to firmly hold the repair channel in place. Some users find it helpful to temporarily bolt the channel through existing shackle mount holes to secure it during welding.
- Welding: Perform a series of tack welds to secure the channel. Once tacked, proceed with full, continuous welds along all contact points between the repair channel and the vehicle frame. Follow standard welding practices for steel.
- Inspection: After welding, allow the welds to cool. Inspect all welds for proper penetration and integrity. Grind down any sharp edges or excess weld material.

4.3 Post-Installation:
- Corrosion Protection: Apply a suitable rust-inhibiting primer and paint to all welded areas and the repair channel to prevent future corrosion.
- Reassembly: Reinstall any components that were removed during the repair process.
- Final Check: Verify that all connections are secure and that the repair does not interfere with any other vehicle components.
5. Maintenance
Once installed, the Kojem Rear Frame Repair Channel requires minimal maintenance. Regular inspection and protection are key to its longevity.
- Periodic Inspection: Annually inspect the repaired area for any signs of rust, cracks, or damage.
- Corrosion Control: If any surface rust appears, clean the area and reapply rust-inhibiting paint or undercoating.
- Cleaning: Keep the undercarriage of the vehicle clean, especially after driving in corrosive environments (e.g., salted roads).
6. Troubleshooting
While the repair channels are designed for specific fitment, minor variations can occur.
- Fitment Issues: If the repair channel does not align perfectly with existing holes, minor drilling or grinding may be necessary to achieve optimal fitment. Ensure the channel is properly seated before welding.
- Weld Quality: If welds appear weak or inconsistent, consult a professional welder. Proper surface preparation and welding technique are crucial.
