Advance Adapters has developed these heavy-duty cable shifter upgrade kits to ensure that you don't get stuck in a range you don't need again. These kits address the weak point in most 4WD systems--the transfer case shifter cable. Advance Adapters made these heavy-duty shifter cables stronger to withstand shift after shift without fail. This is made possible by the stronger mounting points and a heavy-duty cable that will not wear out like the stock unit. Have some peace of mind on the trail with these Advance Adapters heavy-duty cable shifter upgrade kits.
