The BajaKits PreRunner Front Long Travel Suspension Kit enhances off-road performance by providing up to 11 inches of wheel travel and increasing track width by 5 inches total. Engineered for durability and improved handling, this kit uses Trophy Truck grade components to ensure high-angle articulation without failure.
