K350L2. Fits all 1969 to 1980 GM Turbo 350 transmissions. This Combo Kit comes with all of the parts we use in our level 2 TH350 Raptor transmission. The level 2 TH350 Combo Kit is good for motors up to 400 horse power. This transmission comes with our #7 twelve inch torque converter rated at 450 horse power, a black carbon fiber intermediate band for more holding power, an Alto master rebuild kit #032901, and a high performance Fairbanks TransAction Shift Kit #31006. The low / reverse roller clutch is replaced with a much larger late model 700R4 roller clutch. The stock intermediate roller clutch outer race is replaced with a Sonnax hardened race for added strength #35723HD-02. This is the main weak point on the TH350 transmission. Plus you get a free PATC shirt. There’s a 10% discount on this level 2 TH350 Combo Kit.
