Tacoma suspensions are tuned specifically to each grade. TRD Sport has red TRD sport-tuned shocks. The TRD Off-Road grade is equipped with monotube Bilstein remote reservoir shocks for extended wheel travel and greater heat dissipation and includes an end stop control valve (ESCV) that provides increased damping force as the suspension comes closer to full bound stroke. TRD Pro comes with FOX’s new QS3 three-way adjustable internal bypass shocks with remote reservoirs for improved high speed off-road performance and FOX Internal Floating Piston (IFP) rear bump stops to improve bottom out feel. Trailhunter includes new “Old Man Emu” (OME) 4×4 Suspension by Australian-based ARB that is tuned for optimum levels of off-road control and load carrying capability. Limited grade has a new Adaptive Variable Suspension (AVS) system that constantly adjusts damping forces based on changing road conditions. The linear-solenoid-type AVS system has built-in actuators in the front and rear shock absorbers to continuously change damping force based on road conditions to give the new Tacoma a smooth and luxurious ride.
