This kit includes the 312959 dryer belt, (1) 3037050 idler pulley and (2) Heavy Duty 12001541 dryer drum rollers. This kit is designed to be compatible with older style Maytag dryers. The 12001541 drum rollers are notorious for going bad so quickly with cheaper rubber. This kit, however, has taken that into exception and in the process has HEAVY DUTY rubber rollers. Will last much longer than other kits and aftermarkets on the market today. This is not a Whirlpool OEM product.
