Aerospace Aluminum-Alloy

Quarter Midget Axles

Less Weight and Less Cost Than
Titanium and Even Stronger!

Reduced Unsprung Weight = Reduced Wheel Hop

The unsprung weight (which includes axles, wheels, rims and tires) movement of a vehicle due to an imperfect racing surface is inversely proportionate to the unsprung weight. Less unsprung weight will have more grip when tracking over the imperfect surface.

The BAC A3 Quarter Midget Axle will fit all

chassis types and all existing pinch-type wheel hubs, brake hubs, etc.

Not Recommended For Use with Floating Hubs.

Optimized Design Through Structural Analysis
Utilizing aerospace structural analysis techniques, the BAC A3 Quarter Midget Axle is an optimized design with no stress risers. (Typical failure location of all other axles is at the snap ring groove adjacent to the bearing.) The superior strength A3 design is the utilization of the highest strength proprietary aerospace aluminum alloy available in combination with the elimination of all snap ring grooves. This unique A3 axle design is truly the first and only engineered quarter midget axle which through analysis eliminates weight in low stress areas (center section) and increases wall thickness in the highly stressed bearing areas. The axles are gun-drilled to eliminate unnecessary weight resulting in the lightest and strongest axle available. Each A3 axle is supplied with 3 lightweight aluminum collars to locate the axle in the chassis. These same BAC locking collars have been running for years with the BAC kart axle on outlaw sprint karts. They have proven to secure the axle in location through the hardest turns and harshest racing conditions. Each A3 axle assembly also includes 2 sets of aluminum keys (4 thin & 4 thick). The A3 axle kit fits all chassis types and pinch type hubs.
