66-77 Ford Bronco

5.5 inch Suspension

TOMS OFFROAD 5.5 inch suspension lift kits for 66-77 Ford Broncos are built using all high quality components to ensure a comfortable ride and unbeatable off-road performance. Our 11-pack leaf springs give you the best of both worlds, providing a soft ride along with excellent off-road articulation. These leafs include silencing pads between each leaf to offer a quiet ride and the front double military wrap offers added strength and protection against breakage. For the front Coil Springs, we offer progressive rate coils. The softer pre-load spring layer produces a comfortable ride and excellent articulation. As more force is applied (turning, braking, etc.) and the pre-load springs fully compress, these springs progress into a stiffer coil to provide the extra support needed to help limit the unwanted effects of body roll.

About Our Early Bronco 5.5" Suspension Lift Kits

At Tom's Bronco Parts, all of our Suspension Lift Kits for the Classic Bronco include New Leaf Springs or Add-A-Leafs, New Coil Springs, New Polyurethene 14-pc C-Bushing Kits & New Shocks.

For a 5.5" Lift, there are some other parts that come highly recommended for varying reasons. Below are some parts we recommend along with the reasoning behind it.

Tracking Bar Drop Bracket: Helps to center the front end under your Bronco and returns the tracking bar angle to near factory specifications.

Drop Pitman Arm: Corrects the angle where the draglink meets with the tie-rods preventing dangerous steering situations. When all is said and done, the tracking bar and draglink should run somewhat parrallel with eachother.

Extended Front & Rear Drivelines: When you lift the Bronco, it pulls the transfer case away from the differentials pushing the drivelines to be extended past their safe running limits causing them to fail. Extended drivelines will take care of this issue.

Adjustable Tracking Bar: When the Bronco is lifted, the frame and differential separate by the total amount of the lift. When this happens, the stock tracking bar will start to pull the front differential over toward the driver's side. This causes the frame to be off-center in relation to the front differential and is one of the biggest causes of steering issues found when lifting a Bronco. The adjustable tracking bar allows for optimal adjustment to center the front differential under the frame, helping to prevent bump steer and other handling issues.

Adjustable Draglink: In the same way the tracking bar pulls the differential toward the left side of the frame when lifting your Early Bronco, the draglink will also be forced to pull the pitman arm toward the right side. This will effect the centering of your steering box and you will in effect have more turning radius to the left and less turning radius to the right. An adjustable draglink will allow you to dial in the centering of your steering box to regain full turning radius in both directions.

Extended Front & Rear Center Brake Hoses: At 5.5" of lift, the stock front and rear brake hoses will no longer reach from the frame to the differential (if they do they will be VERY tight). This is a necessity to be changed. Some of our base priced kits do not include these hoses. If you have not already installed new extended hoses, make sure you get these whether they are part of the kit you ordered or an add-on.

Extended Rear Emergency Brake Cables: In the same way the brake hoses will no longer reach or are extremely tight, the rear e-brake cables are also highly extended. If the rear cables do reach, extending the suspension in the rear could potentially be limited due to the length of the stock e-brake cables. Extended parking brake cables eliminates this concern.
