Pro Series 300M Floater Shaft
40 Spline, 38-44" Long
With years of competition testing and more top place finishes then we can count, Spidertrax Ultimate Floater Axle Shafts have quickly become the #1 full floating axle among top rock crawling and rock racing teams.

Axle shafts are sold individually (single). Lead-times vary, for an accurate ship date prior to ordering please call or email. Because axle shafts are custom made, payment is taken in full at time of order and orders are non-refundable.
Pricing: $899.00


But what makes Spidertrax axles outperform the competition in ALL areas of quality, strength, and price? Here is a list of key advantages on what makes Spidertrax axle shafts stand out from the crowd:

•Spidertrax starts with only the finest US grade 300M (used for the axle shafts) and aerospace grade E4340 (used for the yokes) billet chromoly. The E in 4340 stands for electric furnace (as opposed to a gas furnace which is more commonly used among our competitors) and yields superior results in heat treatment. They also carry out all CNC manufacturing operations in-house, in Colorado USA. This allows them to provide an unmatched level of quality control while passing significant cost savings on to you.

•Unlike other Dana 60 axle shafts, Spidertrax approach to a two-piece axle shaft design adds an incredible level of strength, durability, and machinability. To start, the two-piece yoke incorporates a unique, ringed web, design which connects and supports both ears securing the u-joint. This greatly minimizes deflection under load, providing a superior level of strength and durability to both the yoke and the u-joint. This ringed web also allows an axle shaft assembly to achieve un-heard-of steering angles, reaching a maximum steering angle of 50 degrees! This design approach also creates machine friendly parts, allowing us to maximize the speed of our in-house CNC machines to pass significant cost savings on to you.

•All heat treatment is done AFTER machining and never before. This provides far more strength than simply working with pre-heat treated material, rough cutting some splines, and calling it good. After heat treatment, they perform a deep freeze, or a Cryogenic freeze as it is commonly called, to the 300M material. Spidertrax uses a superior method for deep freezing that goes beyond simply cooling the part. After the axle shaft is heat treated, it is heated back up to a critical temperature at which point it is immediately deep freezed. This entire process improves the molecular structure of the axle shafts and has been a proven technique, when done correctly, in improving shaft strength and longevity. For those wondering why the 300M versions of these shafts are more expensive than the 4340 counterparts, this process, plus raw material cost, is the reason why.

•Spidertrax turns down the entire shaft so the shaft diameter is smaller than the major diameter of the splines. This provides two key advantages. First, by choosing the correct shaft diameter it allows for an ideal amount of shaft torsion, critical for overall shaft longevity. Second, the axle shaft splines are protected from taking the full load on the shaft, in-turn making the splines much stronger. Anyone who has seen twisted splines on a shaft that has not been machined down like these knows first hand what a difference this can make.

•We are tooled up to manufacture shafts up to 56" in overall length.

•If you're building a complete Spider 9 with Ultimate 60 Knuckles, they know exactly what components you're running and how they are all designed to work together. Therefore, they can make sure your shafts fit perfect in every way. Spidertrax covers all critical areas, commonly missed by the competition, such as corrected adjustments in shaft length based on locker choice.

•All parts come with a "Limited Lifetime Warranty", so you are covered for life from defects in material and workmanship.
