In order to compliment the front suspension, SoCal SuperTrucks installed a Deaver Spring mini pack custom made for the Tundra. Rear shocks include Icon 2.5-inch piggyback shocks that use Icon's "bump zone" technology. Icon has designed this shock to work like a bypass shock increasing compression and rebound in the last two inches of stroke. We hopped into the truck for a quick ride and were pleased with the control the truck had in the dirt. There was no excessive wheel hop, steering shudder, or any bottoming out. The new suspension is a definite improvement and lifts the rear one inch to bring the truck to a level stance.
