1350 Inner Shaft
30 Spline, 6-38 in.

For over fifteen years, Spider 9 axles and components have taken off-roaders to an all-new level of performance. Our unique approach to engineering and manufacturing has repeatedly pushed our rock crawlers to new unreachable places, and we strive to lead the industry every day.

With that, we are proud to release the 30 Spline Inner Axle Shaft. We've designed these shafts specifically for those rock crawlers building around H1 Portal Boxes and Toyota housings & diffs. Integrated into our unique 2-piece webbed-designed yoke & shaft is an axle capable of 50 degrees of steering, the industry's tightest u-joint steering angle in class. The inner axle shaft is constructed out of billet 300M military-grade vacuum quenched steel, while the yoke is constructed out of our competition-proven E4340 chromoly steel.

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

Overview

Aerospace Quality

We don’t use the term “Aerospace” lightly. Yes, these Pro Series Shafts are manufactured out of the finest domestic military grade 300M on the planet, but there’s much more that makes it Aerospace worthy. We follow the strictest AMS Aerospace standards for our heat treatment, complete with double tempering, snap tempering, and cryogenic treatment procedures. Parts are sampled to ensure proper grain structure is achieved up to 0.0003” from the surface, that’s a depth 1/10 the thickness of a human hair! In summary, you’re getting the best material and the best heat treatment on the market.

40 Splined

This may sound a bit obvious, but these Pro Series Shafts are 40 splined. It’s a size that makes perfect sense, especially when running Pro Series 300M Stub Shafts. Deconstructed a bit, you'll find a number of benefits with this increased spline count. Larger spline offers more flexibility in fine tuning the shaft diameter, so that a perfect balance of shaft torsion is matched with the strength of the u-joint and stub shaft. It's not just big, it's sized right. In addition, the 300M yoke is redesigned with larger shaft engagement both in length & diameter, as well as a larger yoke OD for increased strength at high steer angles.

Billet Construction

Spidertrax Pro Series Shafts are manufactured with the finest military grade 300M material, and in our effort of controlling the accuracy of materials we work only with billet stock. Forgings have their place; in the off-road shaft market forgings are used to drive down manufacturing cost. Unfortunately this lower cost tends to create lower quality, with issues of material defects and inconsistency becoming commonplace in aftermarket axle shaft forgings. Whether it's our 1-piece Pro Series Stub or these 2-piece Pro Series Shafts, every part is manufactured out of domestic grade billet material.

Manufacturing Perfection

We pride ourselves on holding the tightest manufacturing tolerances in the business. We take our in-house manufacturing and engineering very seriously and never cut corners for the sake of saving a few dollars. These Pro Series Shafts are no exception to this rule. Shafts are manufactured, heat treated, and then returned to the manufacturing table prior to final assembly to ensure those high tolerance dimensions are perfect. After heat treatment, we bore the holes for the u-joint caps in one single operation, and in that same setup fly cut the insides of both ears to ensure proper u-joint spacing.
