Modifications, Upgrades & Accessories

Whether you’re making a few upgrades or building your dream Jeep from the ground up, Since 1941 Mods is here to help. We install virtually every type of aftermarket Jeep accessory and performance upgrade, transforming stock Jeeps into capable, personalized off-road machines. From lighting, winches, bumpers, skid plates, rock sliders, roof racks, roof liners, ArmorLite flooring, fender flares, inner fenders, air compressors, onboard air systems, recovery equipment, and storage solutions, to lift kits, suspension systems, steering upgrades, axle upgrades, differential covers, wheels, tires, and countless other accessories, if it can be installed on a Jeep, chances are we do it. Our team consists of Jeep enthusiasts who build, own, and use these vehicles on the trail. We don’t just install parts—we use many of the same products on our own Jeeps. That firsthand experience allows us to recommend modifications that deliver real-world performance, reliability, and value, while helping you avoid products that don’t live up to expectations. We also understand that price matters. Unlike many custom shops, we’re happy to install parts that you have already purchased, whether they came from Amazon, Quadratec, ExtremeTerrain, or another supplier. You’re never required to buy your parts from us. The only difference is that while we’ll proudly guarantee the quality of our installation, we cannot warranty the parts themselves unless they were supplied by Since 1941 Mods or covered by the manufacturer’s warranty. Our goal is simple: help you build the Jeep you want while respecting your budget.
