Mustang 31 Spline 4 Lug Axles
Upgrade the axles in your 1979-1993 Mustang with this 31 spline, 4 lug axle kit! If you're upgrading to a 31 spline differential, these axles are the perfect pair! These axles are stock length, 31 spline, with a 4" x 4.25" bolt pattern. Each axle is constructed from a high quality steel, and then hardened, to increase torque capacity 25% over your stock axles! Included in this kit is one pair of rear axles and a set of (8) stock length wheel studs!
Super fast shipping and they are exactly as described. The axle is a constant diameter all the way down not like the stock 28 spline ones. Wheel studs were easy to press in with the harbor freight 12 ton press. Did 2 at at time with no problem. Don't see why you'd need to get any more expensive axles than these!
