Jeep TJ, XJ, YJ SpynTec Conversion 5x5.5

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 around 2008. 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, our dealers, or typically from your local auto parts house.

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 our dealers or can be modified by a local machine shop.
Pricing: $1,550.00
