The Eibach's PRO-TRUCK-LIFT STAGE 1 combines our lift springs and sport shocks with height adjustable clips for this application, so this kit is a front spring-and-damper package, not a spacer or coilover system. The sport dampers are monotube design, 46mm pistons, nitro-coated rods, per the manufacturer's own shock announcement. Owners on user forums say the ride is a step up from stock: one 2021 SR5 owner found it improved over the TRD Bilsteins, and another described the truck as more planted on rough roads.
Against a cheaper spacer lift, the case rests on ride and handling. One owner who replaced a 2.5-inch spacer after adding a winch bumper said the spacer ride was harsh, and that the bumper had caused body roll, and nose dive, which this kit improved. Fitment is 4WD-only: the manufacturer lists this number as the 16+ 4WD Tundra Pro-Truck-Lift Stage 1, and year and trim coverage varies across sources, so check your VIN before ordering. Owners on user forums report about 2.5 inches of front lift at the top clip, with the rear needing a shackle or block to reach about an inch. The manufacturer publishes instructions for this part number, and a spring compressor is needed for the front coil work.
The manufacturer's Stage 2 listing is for a pair of front coilovers plus rear shocks. Stage 1 keeps lift springs and sport shocks with height-adjustable clips instead.
Owners on user forums say the Eibach rear shocks add little or no lift by themselves. The rear rises up to about one inch only when paired with a shackle or block.
The manufacturer lists this part number for 4WD Tundras. Confirm the correct number for your drive configuration with the manufacturer before ordering.
This is a moderate-to-advanced job. Plan on a floor jack, jack stands, a spring compressor for the front coils, a torque wrench, and a good set of metric sockets. Read the manufacturer's install instructions before you start, because the front spring seats and clip positions are set during the install. Expect to realign the truck afterward, since changing front height shifts caster and camber.
