4130 Rear Spindle with 7/16ths wheel studs

$417.00

Most race cars with as much power as we run have large diameter tubular axles. On the outboard side of our driveline, we are stuck with a 50 year old spindle support housing design that dictates an axle diameter of only 1.063 inches. The original axles handled up to 375 HP on tire patches that were 5 inches wide. With twice the power and twice the tire patch, the load on the spindles has gone up dramatically. We would not race on a stock spindle. These come with ARP 7/16th or 1/2 inch wheel studs in either the stock length (for steel wheels), or 3 inch as shown.

Heavy Duty Half Shafts

$866.00

If you are running an engine with less than 500 HP, you are probably safe to go with good, solid 3 inch OEM half shafts. If you have any more power than that, it would be prudent to go with 4130 chrome moly half shafts. We supply these with the best Spicer U-Joints and Spicer flanges.

Super Duty Stub Axles

$768.00

These parts are forged 4130 chrome moly steel. Imagine all that would be wiped out if you broke one of your stock stub axles and the half shaft cleaned out everything in its path. The half shaft is the upper control arm of your rear suspension. When you break a stub axle, the tire on that side tries to lay over, causing a very unsafe moment for the driver. All our racing differentials get two of these. They come as shown with caps, clips and Grade 8 bolts.
