Rear-Axle Suspension Kits for 2011 Toyota Tundra with 6-Inch Suspension Lift

Expert Reply:

Timbren rear axle jounce spring kit # TTORTUN4 is not suitable for your 2WD 2011 Tundra that has a 6-inch suspension lift but there are other kits you can use to add support to your rear suspension.

As long as you do not have an in-bed hitch (no 5th wheel or gooseneck) you can use the Firestone Ride-Rite Air Helper Springs # F2445 along with Ride-Rite Lift Spacers for a 6-inch Lift, part # F2375. For the most convenient operation you can add their Air Command compressor kit # F2158 to give you instant pressure adjustment capability from the comfort of the driver's seat.

Another option for leaf spring installation is the SuperSprings Custom Suspension Stabilizer Kit # SSA4. This does not have the same capacity as the Roadmaster kit (1100-lbs versus 2000-lbs for the RAS) but it offers easy bolt-on installation, zero maintenance and lower cost than a complete air bag setup.

Between all options, for the best cost/benefit ratio I recommend the Roadmaster kit # RAS4618AT.
