How Do I know what Size To Order?

We have a few great tips we use in order to size shackles correctly...

1. Park on a flat level surface, Using your tape measure pull a measurement from the Center of the Front and Rear wheel openings down to the ground or top of tires. "Write these measurement's down"

2. Using your floor jack raise the rear of the truck by jacking up on the trucks tow hitch until you're happy with the stance or at least .750" higher in the rear than the front.

3. Take a second measurement and compare the difference in the two. The difference in the two measurements will tell you exactly how much lift you need to add.

Install Guide:

Coachbuilder shackles and poly bushing: ** TIP, remove the rear lower shock bolts and spare tire before starting the installation , ( TRD Dual Exhaust ) you may also need to remove the rubber exhaust hangers at the tail pipe in order to allow exhaust to hang down during installation. With the truck up in the air and frame supported, lower rear axle until there is no load on the rear leafs (full droop) keeping floor jack in place.  Remove OE nuts on the OE shackles and slide shackles out from the frame rail and leaf packs.

 ** Using a ball joint press tool remove the OE rubber bushings located in the rear leaf spring eyelets. Separate new poly bushings from steel center sleeves and grease all outer surfaces of each part before installing the new bushings into the rear leaf spring eyelets.  Using a soft hammer tap in each bushing and then the center sleeve. Any grease remaining apply to the outer surface of the bushings where the shackles and bushings make contact.

 ** Use the second grease pack supplied to coat the smooth portion of all 4 bolts before installing into the shackles. Once the truck is back down on the ground torque to 70 ft lbs and reinstall your spare tire and lower rear shock bolts.
