Overview of TrakMotive AAR CV Axle Shaft KA-8126

The TrakMotive AAR CV Axle Shaft KA-8126 is engineered for reliable driveline performance in Kia Optima vehicles. Designed as a new replacement part, it ensures precise fitment and durability for your vehicle's front-wheel drive system.

  • Compatible with Kia Optima models
  • Includes ABS tone ring with 48 toothed ring teeth
  • Neoprene boot material for enhanced joint protection
  • Hex head axle nut included with stake locking type
  • Overall compressed length of 25.75 inches (654 mm)

Features and Specifications

This CV axle shaft features a 48-tooth ABS ring with a toothed design, providing accurate wheel speed sensor readings essential for ABS functionality. The included ABS tone ring ensures seamless integration with the vehicle's anti-lock braking system. The neoprene boot material offers resistance to wear and environmental factors, protecting the inboard and outboard joints.

The axle nut is a hex head type measuring 1.26 inches (32 mm) across flats, with a height of 0.94 inches (24 mm) and a length of 1.45 inches (36.95 mm). It uses an M22x1.5 thread size and a stake locking mechanism to secure the axle firmly in place. The inboard joint is a male type with 28 splines, while the outboard joint is conventional with 30 splines, both utilizing spline shaft connection styles for precise fitment.
