Another WERKSracing SRT-4 transmission exclusive from the originators - not the copycats!!!Our new 1,3,5 gear shift extension lengthens the 1st, 3rd and 5th gear shift by 20% over stock. Eliminates 1st, 3rd and 5th gear grinding and pop-out for good!Our R&D has shown that due to differening manufacutring tolerances inside the SRT-4 transmission the synchro is not fully engaging the gear itself in many transmissions. Only engaging sometimes half way onto the gear causes grinding and pop-out on both upshift and downshift. Even when replacing the synchro and gear itself makes no change, our little unit is the cure!You can even send in your shifter plate and we will install the part for for only $25.00 plus shipping both ways.
