The Spidertrax Pro Series Housing makes history by becoming the first 9″ housing designed specifically for professional rock racers. Every component of the Pro Series Housing, from the one-piece 1/4″ thick center shell to the 3/8″ thick third member face plate, is manufactured out of 4130 domestic grade chromoly steel. Best of all, every 3-1/2″ OD x 1/4″ wall 4130 housing tube is heat treated to a tensile strength of 150,000 psi, roughly 2-1/2 times the strength of 1026 DOM. Pro Series Housings are kept in stock and ready for same day shipping.

Chromoly construction:
Every component of the Pro Series Housing, from the one-piece 1/4″ thick center shell to the 3/8″ thick third member face plate, is manufactured out of 4130 domestic grade chromoly steel. Compared to traditional mild steel housings, this gain in material quality provides an ultimate strength increase of over 50%.

Ground clearance:
Fine in the desert, but an oversized housing fails in the rocks. That’s why every Pro Series Housing provides unmatched ground clearance. At 15°, the bottom of our housing measures only 5″ from housing tube centerline.

Easy inspection:
A generous 1-5/16″ diameter fill opening makes general gear inspection and filling easy. We also positioned the fill opening high up on the Pro Series Housing, so oil level can be set as high or low as required for your 9″ third member. Of course our Spidertrax Oil Fill Cap is also included with every Pro Series Housing.

Ultra lightweight:
Unsprung weight is a vital factor in rock racing performance. At 65″ in length (far longer then necessary even for a full size axle), our Pro Series Housing weighs under 70 lbs. This is less than half the weight of a traditional Dana 60.

Racing hardware:
What performance housing would be complete without racing grade third member hardware. Every Pro Series Housing comes standard with our Pro Series Hardware Kit. Each kit comes complete with Grade 9 cross drilled 12 point bolts to ensure your third member stays tight, even in the toughest of competitions.
