What is KP540
• 40-spline, 1550 U-joint compatible kingpin wheel end system built around serviceable spindle and Timken bearing architecture for strength and field service.
• Industry first 40-spline manual locking hub option, plus drive slugs for competition use.
• Oversized Timken bearings with wide spacing for load distribution and impact resistance. Bearings are off-the-shelf replaceable.

Options covered in this video
• Shafts and U-joints: 1550 U-joint compatibility, 40-spline shaft options, RCV style choices, and when 300M vs 4340 makes sense
• Hubs vs slugs: trail/road friendly manual hubs vs simple, bomb-proof slugs for comps and extreme use
• Steering: high steer arms, tie-rod and drag-link placement, ram mount considerations for full hydro

Why KP540 for hardcore builds
• Strength through 40-spline interface and large 1550 joint window
• Serviceability with common bearings and service parts
• Configurable for your use case: weekend crawler to competition buggy
