GAPLESS SPIRALOCK INTERMEDIATE SPRAG RETAINING RING
4CC/GSISRR

It is a common occurrence for the OEM intermediate sprag retaining ring to be ejected from its groove in high performance and competition applications, resulting in parts failures. This high quality heat treated snap ring features a full 360 degrees of engagement ensuring positive ring retention in its groove under extreme duty and high rpm operating conditions. A must on all TH400 build ups.

HEAVY DUTY INTERMEDIATE CLUTCH SNAP RING
4CC/HDISR090

In its relaxed state, the OEM snap ring outside diameter is much greater than in its installed position, requiring increased deformation to permit assembly. This results in a ring that is highly stressed as installed. Each time the clutch applies, the ring must absorb the force. This compromises the structural integrity of the ring, often resulting in shattering. This high quality heat treated snap ring features an increased cross sectional area and will not fail under extreme loading conditions. A must on all TH400 builds.

INTERMEDIATE CLUTCH SNAP RING SUPPORT
4CC/SRS

Most competition valve bodies installations require the omission of the intermediate band from the transmission case. In these cases the intermediate band anchor pin may be removed from the case, permitting the installation of this unique intermediate snap ring support. This item will stabilize the snap ring in the area of the case that is void of any snap ring support lugs, reducing the chances of lug and snap ring blowout. A must for competition applications.

HI-RATE DIRECT CLUTCH APPLY/RELEASE SPRINGS
4CC/HRDCRS

These hi-rate direct clutch apply/release spring are engineered specifically for hi-output TH400 applications.  The additional spring force requires  that a higher clutch apply pressure value be reached  in the direct clutch circuit before the clutch piston can overcome the opposing spring force and apply the clutch pack. This results in increased intermediate clutch pack torque capacity furnishing quicker and firmer shifts with reduced slippage. These springs will also improve transbrake set up,  transbrake reaction time, reduce centrifugical apply of the direct clutch, also speed up direct clutch release during automatic, forced or manual 3-2 downshifts. Furnishes improvements you can feel.
