The Ford ZF transmission is the best manual transmission available for your Early Bronco. This is a state of the art five speed transmission that shifts smoothly and has an excellent low gear 5.71:1 as well as overdrive .72:1. ZF transmissions will bolt right to your 302/5.0L or 351 Windsor/5.8L. BC Broncos has developed a complete install kit to bolt the ZF to your Dana 20 complete with cross member, hydraulic master and slave cylinder stainless steel flex line and clutch rod. You must use a ZF transmission from a 1988-1999 Ford 4X4 pickup with a small block engine (302/5.0 or 351/5.8). Your stock EB flywheel and clutch will work with the ZF too. The ZF installation does not require a body lift, only a 6" X 7" hole in the tunnel cover.

TIP: The ZF uses 3.2 qt's of Dextron ATF or MTF

When you buy a ZF make sure they give you the upper and lower shifter

If not it will cost you more, make sure you factor that into your deal.

The Gear Gawker clear cover for the ZF, this is a great way to keep an eye on your fluid level but if you look close you can see if their are any metallic partials in the oil indicating a problem without taking the cover off, This is an easy way to check your ZF before you go to an event. But are they strong? These are made of 1/2 inch thick poly carbonate glass made for the view slits of armored vehicles. These covers will take a serious beating and hold up to temps over 600* without failing.

This precision machined adapter kit allows mating the NP435 to the Early Bronco Dana 20 transfer case, making the swap clean and easy. Note: This adapter requires an intermediate adapter (housing and shaft) from a 6 cylinder Bronco. You must provide this. BC Broncos sometimes has these on hand--call for pricing and availability.
