DRIVE TRAIN
BREATHER FILTER


Fresh Air Vent System

With this CNC machined 4-port block and filter system, you can run your front & rear differential, transmission & transfer case vents high up on the fire wall to get them as far out of the mud and water as possible. In the event of a rollover, this vent system will prevent fluid loss by absorbing it into the filter. The cotton filter is reusable and washable - just wash and reoil. A great addition to any 4x4!

ZF TRANSMISSION ADAPTER

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 as well as overdrive. ZF transmissions are easy to find and will bolt right to your 302 or 351 Windsor. BC Broncos has developed this adapter to mate the ZF to the Dana 20 transfer case. You must use a ZF transmission from a 1988 or later Ford 4X4 pickup with a small block engine (302/5.0 or 351/5.8). You can fabricate your own crossmember or use the one we have specially designed for this application (see below). Your stock EB flywheel and clutch will work with the ZF too. We will soon offer brackets for using a hydraulic clutch. The ZF installation does not require a body lift, only a 5" X 8" hole in the tunnel cover.

300M DANA 20 OUTPUT SHAFT

The new Dana 20 output shaft is made for B.C. Broncos by one of the best gear manufactures in the U.S. The shafts are  being made to very close specs to match the stock Dana 20 output shafts in every way except strength. The 300M material is much stronger so the shafts can be made to stock specs, it is the same material that the CTM U joints are made of.  The company that makes this shaft also makes crankshafts and axles for some of the top fuel dragsters.

Some tech info. from the manufacture,

Thread: J-series controlled radius root for improved strength .

 Inside corners: Generous blend radii avoids stress  concentration .Splines: Precision hobbed for improved mating part fit and alignments.

 Bearing Journals: Ground to precise size for correct fit, surface finish and concentricity.

Material: Uniquely alloyed and tempered, vacuum melted, 300M steel produced specifically for highly stressed, torsion applications.

CTM RACING U-JOINTS

This is the U-joint we've all been waiting for! How many of us have upgraded from a Dana 30 to the stronger Dana 44 only to find out that we're still breaking u-joints, especially with larger tires? These might possibly be the last set of U-joints you will ever buy for your Dana 44. Made of high strength alloy steel, these U-joints use a unique bronze bearing rather than needle bearings to allow for larger trunions. These have been put to the test in the most extreme conditions, and no failures have been reported to date! CTM backs these U-joints with a lifetime warranty.

Look for B.C. Broncos' write-up on the CTM Racing U-Joint install in the April '02 issue of 4 Wheel Drive & Sport Utility magazine!

These complete third members are ready to drop into the 9" rear end of your Bronco.

A new ring and pinion are installed with your choice of gear ratio, with your choice of differential/traction device (see pricing). All new bearings, seals and internals are used and everything is professionally assembled. These units are sold without the pinion yoke as you may re-use your existing yoke due to the use of a solid pinion spacer during assembly rather than a crush sleeve. No core is required. Third members are covered by a 12 month, unlimited mileage warranty.

JP ROCK EATER TRANSFER CASE GEARS

The 4.86:1 JP Rock Eater gears make it possible to drive to the trail head and have the low gears to crawl on the trail. The 4.86 (lowest on the market) T-case gears give you a lower final gear ratio with 3.5:1 differential gears than you get with the stock 2.43:1 T-case gears and the 4.11:1 or 4.88:1 differential gears. Here is the math:

Stock 3 sp. 1st. gear =2.99:1
Stock T-case low range =2.43:1
Rock Eater low range =4.86:1
4.11 Differential =4.11:1
3.50 Differential =3.5:1

3-Speed
1st Gear
X T-Case

Ratio
= Final Drive
("Crawl") Ratio
2.99 X 2.43 (Stock) X 3.50 = 25.43:1
2.99 X 2.43 (Stock) X 4.11 = 26.86:1
2.99 X 2.43 (Stock) X 4.88 = 35.46:1
2.99 X 4.86 (JP Gears) X 3.50 = 50.86:1
2.99 X 4.86 (JP Gears) X 4.11 = 59.72:1
2.99 X 4.86 (JP Gears) X 4.88 = 70.91:1

The difference in gear ratios is quite evident in this comparison of the stock 2.43:1 gear set (top) vs. the 4.86:1 JP Rock Eater gear set (bottom)

The JP Rock Eater gears are the highest quality gears made and will fit in the stock Bronco Dana 20 T-case with no machine work needed. No need to change the drive shafts and no need to cut holes in the floor for more shifters.
