Introducing the KP540 Front Axle – East Coast Gear Supply’s newly engineered, 40-spline kingpin steering axle designed for today’s big-tire, high-horsepower off-road rigs. In this video, Ian Johnson of Big Tire Garage walks through the complete KP540 builder kit: massive kingpin C-ends, custom forged knuckles, a purpose-built 40-spline spindle with 80,000 lb yield strength, oversized Timken bearings, and off-the-shelf brake compatibility .
What You’ll Learn:
• Why a ground-up approach was taken to built the ultimate wheel ends - the next evolution of 40 spline Inner C, Knuckle, Spindle, Wheel Hub
• What's included in the KP540 Builder's Kit
• How the Massive Kingpin Inner C provides maximum performance over Balljoints Inner Cs.
• How the kingpin delivers long-term serviceability with simple bushing and bearing replacements with parts that have been on the market for decades
• How the KP540 Knuckle was engineered to out perform existing knuckles
• How the KP540 Hubs are larger than current hubs to maximize larger bearings
• Why a larger true 40 spline spindle is necessary
• Why we chose to use OE brakes and bearings versus exotic, single-source wear components
“This is all 100 % designed together as one cohesive unit — not bolting junkyard parts to aftermarket bits,” says Chase Perry, founder of ECGS
