Bigger tires need clearance—and adding that suspension lift is only half the battle. Spidertrax Off-Road 6061-T6 billet aluminum spacers are an easy way of spacing out front and rear axles that run OE wheels. This added spacing is necessary for keeping those larger tires from crashing into your frame rails and suspension links at full turn. Simply bolt-on like a wheel, and off to the trails you go. Each kit comes with two wheel spacers, 10 wheel studs (pre-installed), 10 lug nuts, and a package of thread locker. Each wheel spacer is anodized in blue, using a double anodizing process for twice the corrosion resistance. In addition, each wheel spacer is wheel and hub centric for a perfect fit. The spacers are available in a variety of thicknesses, center bore diameters, and thread sizes. Order the pair recommended for your vehicie.

Spidertrax Off-Road Ultimate rotors are designed and intended for use on Spider 9 axle assemblies. Building on the same platform as the previous generation Spidertrax Pro Series rotor, the Spidertrax Ultimate rotor delivers many of the competition proven benefits our brake rotors are known for, but at a fraction of the price.

Spidertrax Off-Road Spider 9 axle housings step up the level of performance and looks of today's off-road machines. Building on the platform of the company's top placing housings, the latest Spider 9 housing is stronger (ARP studs, accepts 9 in. and 10 in. gears), more versatile (68 in. OAL, works with standard and mid-engine setups), and just downright sexier (TIG-welded on outside, machined face). If you're looking for many of the 9 in. housing benefits, at a fraction of the price, Spider 9 housings are the perfect solution. Every Spider 9 housing comes with third member ARP studs and Nylocks. Fill bungs and caps are sold separately. Additional details: * Strong: Every Spider 9 housing is constructed with a one-piece 1/4 in. thick shell, a 3/8 in. thick face plate, and 3 1/2 in. x 1/4 in. wall axle tubes. Spidertrax also redesigned the faceplate to allow the use of both 9 in. and 10 in. gears. * Secure: Best to keep those 9 in. and 10 in. gears where they belong, inside your Spider 9 housing. That's why Spidertrax redesigned the shell to work with ARP studs. No matter how many miles, your third member will always stay tight. * Complete: All Spider 9 housings are precision-machined for genuine ARP third member studs, included with every order. Plus, at 68 in. in length, these off-the-shelf housings work for almost any off-road application. One housing, everything you need.

Spidertrax Off-Road Ultimate steering knuckles set the standard for rock crawling and rock racing performance. They now include 7/8 in. spherical bearings and 4340 Spider shoulder bolts across the line. In addition, they feature internal gussets on both upper outer knuckle and lower inner knuckle, adding crucial strength from extreme steering forces and those high impacts from jumps. Ultimate knuckles are designed for Ultimate unit bearings, Ultimate U-joints, and 4140 bolt-on high steer arms (sold separately). They install on any Spider 9 housing with 3 1/2 in. O.D. tubes. * CNC-machined: Tight tolerances are necessary for proper fitment. Post welding, all inner knuckles are CNC-machined. This provides not only a perfect 7/8 in. spherical bearing fit but a precise tolerance between upper and lower spherical bearings. No guesswork, no compromise. * 7/8 in. bolts and bearings: The spherical bearing assembly consists of a 4340 Spider shoulder bolt, shim washer, spherical bearing, shoulder washer, and Type C nut. Combined, each knuckle can withstand over 21,500 lbs. of axial loading and over 130,000 lbs. of radial loading. No grease, no weak links, no hassle. * 50 degrees of steering: An OEM-style 60 knuckle can turn only 38 degrees. Ultimate knuckles can turn all the way to 50 degrees, tighter than any steering knuckle on the market. Plus, the use of a 6-bolt interlocking chromoly steering arm makes them one of the strongest, as well (steering arms sold separately). * Internal gussets: Ultimate knuckles take performance to an all-new level with the addition of internal gussets. Upper outer knuckle gussets add critical strength for steering, while lower inner knuckle gussets add extra strength for those high sailing jumps. They're simply Spidertrax's strongest Ultimate knuckle yet.

Spidertrax Off-Road's all-new 1480 40 spline front axle stubs are a reinvention of their already proven 35 spline stub shafts. Manufactured from billet 300M aerospace material with an integrated positive locking design—all while achieving 50 degrees of steering—they're the next best thing in stub shaft technology… and the last stub shafts you'll ever need. These 1480 40 spline stub shafts are designed to work with 60 style U-joints and Spidertrax 40 spline Ultimate Unit Bearings. * Aerospace Quality: Spidertrax follows the strictest AMS Aerospace standards for their 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 in. 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. * Locked: Turning 40 degrees is impressive, but Spidertrax axle shafts can turn 50 degrees. Engineers achieved this by positively locking the shaft to the Ultimate Unit Bearing with a billet aluminum cap and cap screw. Keeping that stub shaft tightly secured not only helps with driveline vibration, but helps with overall strength of shaft and U-joint. * 40 Splined: Each stub shaft is 40 splined—a size that makes perfect sense, especially when running properly paired inner axle shafts. When sized with the same shaft diameter as inner shafts, stub shafts end up taking the full punishment in your front-end. The stub shaft should be "stronger" than an inner axle because unlike an inner axle, stub shafts have little room to twist, making them more prone to failure. An added bonus: with many drivers running 40 splined rear Ultimate Unit Bearings, having the same unit bearing up front makes for better serviceability and part simplicity.

The Spidertrax Off-Road high performance inboard oil seal kits are the perfect solution for sealing up your Spider 9 housing. Spidertrax starts with billet 6061-T6 aluminum and then machines a fully rebuildable seal housing that's designed to accommodate three external O-rings and two high performance axle shaft seals. Both O-rings and seals are pre-installed. With up to five total sealing surfaces, these inboard oil seal kits ensure oil stays where it belongs—inside the housing. The seal is designed to install on the inboard side of your Spider 9, near your differential. These kits come with one aluminum seal housing, three O-rings, two pre-installed high performance axle seals, and set screw. Key advantages include: * Designed to work with 1/4 in. tube thickness Spider 9 axle housings * CNC-machined 6061-T6 aluminum seal housing is fully rebuildable—both O-rings and axle shaft seals are available separately so servicing your seals is not only possible, but cost-effective * Three O-rings secure the aluminum seal housing inside the Spider 9 axle tube—the aluminum seal housing installs toward the differential side of the housing, so oil stays completely out of the axle tubes * High performance axle shaft seals (two are already pre-installed for you) are designed to accommodate shaft diameters from 27-spline all the way up to 40-spline—they are so stretchy in fact that they also handle almost any kind of axle shaft misalignment * Using the included set screw, each aluminum seal housing is designed to be securely locked inside the Spider 9 housing—this way you know the seal housing stays where it is supposed to when you install your axle shafts
