Dos PiezasTM 2.2 KompilationTM 2-Stage Foam - 2 Inner and 2 Outer per packet.

Tear Up the CompetitionTM with Pit Bull Tires' Officially licensed Dos PiezasTM 2.2 - 2-Stage Foams.

Dos PiezasTM Dual Stage foams Tear Up the CompetitionTM by offering incredible side-hill ability, controlled tire-flex with a firm tread-bite that allows lugs to work individually on the toughest terrains.

Dos PiezasTM 2-Stage Foams work with popular 2.2 tires, but in particular, when used with our Pit Bull 2.2 Rock Beast® XOR Komp KompoundTM tires (PB9001KK), our Rock Beast II 2.2 (PB9002NK), or our Growler 2.2 U4 edition w/ Alien Kompound, our Dos PiezasTM KompilationTM Foams cause serious Symbiosis.


2 Inner and 2 Outer Foams per packet



  • Stage 1 - The Inner Stage supports the critical part of the tire's carcass, keeping beefy crawlers and tall 2.2 tires stable and predictable.
  • Stage 2 - The Outer Stage provides the deadening effect you need for hardcore climbing, sudden hopping and controlled bumping. Stage 2 also refines many rock crawling tire needs when hitting the big rocks and deep holes. Both stages of foam dampen, as well as react quickly enough for high speed runs seen in crawling and rock racing. No modifications necessary with our Dos Piezas...they are ready to go right from the package.
  • Part# – PB9001FM PIT BULL® Dos PiezasTM Two-Stage 2.2 R/C Foam
  • (2) Two Inner and (2) Two Outer Foams per packet & (1) Decal sheet.
