The Archive Garage 2022+ Tundra Rear Shock Relocation Tower Kit allows fitting up to 12" travel shocks without spacing bumpstops or lifting rear of truck.  The stock truck has a tiny amount of droop travel and articulation, and you'll top the shocks out (fully extend) even during street driving.  

1. The relo kit can stuff up to 19" collapsed length.
2. Mount tabs are 1.5" wide with 1/2" thru bolt (M12 bolts avail.)
3. Fit up to 3.0 3-tube bypasses (Check out 1G Raptor offerings here) 
4. NOT FOR COILOVERS, smooth-body shocks only.  You do not want to move the bending point of the frame rails forward from where Toyota engineered the coil buckets.  
   
5. Extended brake hoses are required!
6. May not require wheel spacers or even aftermarket wheels depending on the shock body size used.
