Solid Axle Industries 88-07 Jeep TJ, YJ, XJ SpynTec Conversion Kit

SpynTec Kit Overview

Combined, the Jeep Wrangler YJ, Wrangler TJ, and Cherokee XJ have to be the most popular off-road vehicles of all time. Unfortunately all of these Jeeps have unit bearings and do not have lockout hubs. When larger tires and heavy accessories are added to a vehicle to make it more capable, the driveline suffers. To make matters worse, if your stub shaft breaks, your unit bearing will separate leaving you stranded.

Warn introduced a very popular kit several years ago allowing fixed spindle hub conversion to alleviate driveline stress, but discontinued it about a year ago. SpynTec™ Industries is proud to announce a similar kit designed to add a fixed spindle, internally splined forged steel hub, serviceable wheel bearings, and lockout hubs to your Jeep.

The kit was designed using readily available components. The core of the SpynTec™ kit consists of forged steel hubs and forged steel spindles. Common items like bearings, seals, shafts, and lockout hubs are readily available direct from SpynTec™ Industries, SpynTec™ Industries dealers, or typically from your local auto parts house.

The TJ, YJ, XJ SpynTec™ kit increases your overall axle width by half of an inch on each side. Factory brake systems work perfectly with the kit which uses a very common and inexpensive modified late model Jeep CJ rotor. The modified rotors are available from SpynTec™ by SpynTec™ Industries dealers or can be modified by a local machine shop.

Note: Uses 5 on 5.5 bolt pattern, and modified Jeep CJ Rotors.

Benefits:

• Eliminates unit bearing hub assemblies prone to breaking
• Inexpensive to maintain
• Fully rebuild-able
• Reduces drive-train wear
• Increased fuel economy

Kit Includes:

• Forged hubs
• Forged spindles
• Includes all bearings, races , seals, and spindle nuts
• Premium locking hubs
• Wheel Studs
• 30-Spline Stub Shafts
• Installation Directions

Note: Actual product may vary from images shown.

SpynTec Hubs

All SpynTec™ Industries hubs start out as steel forgings and not castings like other manufacturers. Hubs are turned and sent off to the gear cutter for the internal splines and the gear cut external ABS tone rings. The hubs are finally bright zinc plated for a durable finish.

Spindle forgings are rough turned, heat treated, then final machined. This is the only way to guarantee a spindle with minimal run-out.

SpynTec™ Industries has also revolutionized the hub conversion kit market by offering the only conversion kit that seals off the ABS reluctor ring and sensor from the elements and road debris. This is just one of the extra steps we take to provide you with the best designed lockout conversion kit available in the marketplace.

Rather than sending you a box of parts, SpynTec™ Industries partially assembles every kit. When your kit arrives, you'll be glad to know that studs and races are pressed in the hubs, spindle bearings are installed in the spindles, and axle slingers are installed on the axle shafts.
