    NOTE: This kit is primarily designed to only be driven in 2wd at speed on the road and that 4wd is only to be used off road or adverse slow speed conditions due to drive line vibrations at high speeds. Double cardan driveshaft may be required to help eliminate some of the high speed 4wd front driveline vibration when kits are 5-8" high.

The Plascoating on the components is a performance polymer alloy coating specifically designed to provide a long lasting, tough coating for exterior applications. The Plascoat finish is especially resistant to stress cracking with improved abrasion and impact resistance as well as a great way to protect against adverse weather conditions, detergents, salt spray and other typical airborne pollutants.
