Legal modification plan for the Beijing BJ40L: Replace the front and rear bumpers with MR Expedition manganese steel bumpers, install a winch, remove the wheel arches and replace them with Laura wheel arches, and add spotlights on the MR four-door version roll cage roof rack or install an A-pillar spotlight bracket on the two-door version roll cage roof rack. Currently, modifications require cooperation with a qualified manufacturer or modification workshop. The manufacturer must then register the modified vehicle with the public security bureau before it can be licensed. Many modified vehicles are not allowed on the road mainly because they have been modified privately, affecting the vehicle's structure and other aspects. Generally, very few modified vehicles are permitted on the road, so modifications must strictly follow the legal modification plan for the Beijing BJ40L. The Beijing BJ40 has four versions: S, P, C, and SE. The S series includes the BJ40 Rainforest Expedition Edition and the BJ40 Ring of Champions Edition; the P series is the BJ40 Blade Hero Edition; the C series is the BJ40 City Hunter Edition; and the SE series is the BJ40 Tribute 2020 Edition, which is a two-door short-wheelbase version.

Legal modification options for the Beijing BJ40L, based on my experience, prioritize small changes that don’t affect safety. As a daily commuter, you can replace the rims but keep the original size—don’t exceed standards. Adding LED daytime running lights or fog lights is fine as long as the brightness isn’t too strong to pass inspections. For the interior, adding leather seat covers or small decorations can be easily registered without hassle. Opt for AT all-terrain tires that match the factory specifications to enhance the off-road feel. Avoid modifying the engine or exhaust system, as this is illegal. Also, refrain from arbitrarily lifting the body height to avoid fines. After modifications, remember to regularly check bolts to ensure they’re secure. Spend time on forums to see what fellow enthusiasts share and consult 4S stores for peace of mind—this way, you can personalize your ride without breaking the law, making driving even more enjoyable.

Legal modifications to the BJ40L should start with off-road needs. I've been off-roading for ten years. Replace the tires with KO2 all-terrain ones, ensuring the diameter change doesn't exceed 3% for good grip and compliance. Add a winch to the front bumper but ensure sufficient strength for rescue purposes; upgrade to LED auxiliary lights but include a switch to disable them at night. An electronically controlled differential lock is optional to enhance escape capability, as long as the core structure isn't altered. Avoid excessive suspension lifts to prevent inspection issues. After modifications, always perform wheel balancing and four-wheel alignment to ensure driving safety. Protect your vehicle on off-road trails—avoid reckless modifications like exhaust or body size changes. Remember the rules to enjoy long-term off-roading fun.

For legal modifications to the BJ40L, I'm a professional enthusiast. Change the wheel design but keep the original size; choose off-road tires that match the factory specifications. Interior upgrades like adding navigation and leather seat covers are within limits. Installing fog lights with compliant brightness is fine, but avoid modifying the engine or chassis as it's illegal. Recommended to start with small accessories like mud flaps and side steps—just ensure they're sturdy enough. Don't forget to register the modifications with the DMV to prevent issues. Simple and practical upgrades can enhance daily convenience.

Safety first when modifying the BJ40L, my principle is to only make permitted changes. Wheel and tire sizes must remain consistent; lighting like fog lamps should comply with brightness regulations, and interior decorations must be securely fastened without looseness. Avoid illegal and dangerous modifications such as exhaust system alterations or lifting the body. For off-roading, adding certified front bumpers or skid plates is acceptable, but always have the modifications inspected at a testing station to ensure stability. Minor modifications can be enjoyable, but don't take unnecessary risks.
