These are great for extra stopping power. Especially if you have larger tires or after market axles. 1 Year warranty, and FREE SHIPPING (UPS ground) in the lower 48 US.

These heavy duty power brake conversion kits convert a single diaphragm booster to a dual diaphragm setup which creates more stopping power with less pedal pressure.

interesting...

Question though...

DDBXJ1
Fits:
* Jeep Cherokee (1987-2001) w/ or w/o ABS brakes.
* Jeep Comanche (1987-1992) w/ or w/o ABS brakes.
* HD Dual Diaphragm Booster w/ 1-1/8" Bore Master Cylinder

That kit...
How does it compensate for the different length push rods and brake light assemblies? Does it come with different push rods for each year break? I think they are 87-90, 91-94/95, 95/96-01?

This would be great if it did?

 

They are a matched set of booster and master cylinder. There should be no reason to adjust anything. They are a direct replacement. Unlike other boosters you may have "boosted" off a different rig, then find the proper adjustment/install parts to make it work.

So this XJ one has both the flat spot on the pedel rod for the renix era brake light switch as well as the correct length as say a 97? thats odd..

 

The rods are ajustable. I am getting an image of the said area in question and will post it as soon as possible.

 

Cool!

 

Here is the image of the rod that comes with the DDBXJ1. Obviously not assembled product image.

 

Great prices on this upgrade. Check out the new link for the Cherokee part number.

Namaste,

Shipping these anywhere in the lower 48 US. Get huge improvement in stopping power.

Namaste,

Allen

 

Already shipped one out to Italy via APO. Who wants one as well. Get the additional stopping power you need for those heavy tires.

Have a blessed and prosperous day!

Allen

 

This is a great upgrade for your rig. If you are in need of more braking power but do not want to go hydro assist or can not afford it, get this one. If your brakes are iffy and you need to replace the booster or master cylinder anyway, look at this option.

Post up or PM. Have a great day and wheel safe.

Namaste,

Allen

 

Great deal for those of you that put on new and bigger tires. Do you have a leaking or weak brake booster? Is your master cylinder original equipment? Here is your deal to take care of both.

Namaste,

Allen

 

Got new larger tires and need some better stopping power? Have to replace your master cylinder and booster anyway. Get in on this great deal!

Thank you for your business. I am truly grateful.

Namaste,

Allen

 

Get some extra braking power while replacing that leaking booster and master cylider. 12month/12000 mile warranty. Post or PM to order.

Have a fantastic day!

Allen

 

New pricing but still available.

Namaste,

Allen
