Buying Guide: Key Purchase Considerations
- Vehicle compatibility: Confirm whether the kit suits Swing Axle, IRS, or rear-only upgrades for your specific Baja Bug or dune buggy model.
- Mounting hardware and compatibility: Look for a kit that includes mounting plates, templates, or adapters that minimize custom fabrication.
- Adjustability: Prioritize kits with adjustable ride height and coil-over compatibility to tailor handling for off-road and street use.
- Armor and reinforcement: If you’re upgrading A-arm mounts, consider kits that reinforce mounting points to prevent flex and improve durability.
- Installation complexity: Some kits require drilling, alignment, and precise torques. Gauge your workshop capabilities before purchasing.
- Future upgrades: Choose systems that accommodate common coil-over shocks and springs for easier long-term maintenance and upgrades.
