So you added some serious power to your naturally aspirated car. Unfortunately the stock differential in vehicles not originally equipped with a supercharger is small and not up to the task of putting serious power down to the ground. Our kit allows you to upgrade your stock non-HD 4T65E to a heavy duty unit. Best of all, installation takes just a couple hours and is very easy. Our kit includes everything needed to convert your non-hd transaxle to an HD unit:
- Heavy Duty Differential
- Heavy Duty Differential cover
- GTP Halfshaft (completely assembled)
- Heavy Duty Output shaft
Stage I W Body Store axle available for an extra charge.
Differential cover, differential, and output shaft all used and fully inspected prior to be chosen to be included in our kits. Parts are warranteed for 90 days from date of received shipment.
Why a W Body Store kit? W Body Store kits come completely assembled and ready to install, utilize proven components, include the HD output shaft, and do not have a core charge. We consider this to be the most comprehensive kit on the market to date. |
