These are the Level 5 Axles kit for the 2003-2005 Neon SRT4 5-Speed. The axles feature our Ball & Cage inner CV's with a spline plug into the differential made from aerospace grade material. The center bars are larger 36 spline made from high grade aircraft quality material, up from the 32 splines found on the Level 3 axles, and are significantly more torsional than the factory axle bars. The outer CV is a direct fit to the factory wheel hub, but uses our proprietary cage and race set made to withstand the stresses of high horsepower use and includes ABS rings.
