Raise Frame

Lift Kit for Spring-Leaf and Torsion Bar Flagstaff Campers

The raise frame option lifts the camper box, improving the clearance between the ground and the camper (particularly the camper's bumper).

Leaf-Spring Lift Kit

Flagstaff's OTG, LTD, and MAC Series use a solid axle with leaf-spring suspension. To raise the frame we move the axle from on top of the leaf-springs to the bottom of the leaf springs. This lifts the camper box approximately 4". Here are some examples of lifted leaf-spring campers (and with optional tire upgrades):

NOTE: The axle has a positive camber to assist with proper tracking and tire wear. New axle saddle mounts must be welded to the axle 180 degrees from the existing axle mounts such that the camber stays the same once the axle is mounted under the springs. Otherwise, merely flipping the axle from the top of the springs to under the springs will result in an upside-down axle with negative camber and the camper may track erratically and exhibit premature tire wear. This procedure is included in our raise frame option but we note it here in case someone wants to do their own lift.

When a load (like the camper and its gear) is placed on the axle, the axle bends slightly. With the proper camber, the trailer should tow nicely and the tires wear evenly.

If the axle is flipped and reattached to the leaf springs without the proper mounts, the camber is upside-down:

When a load is placed on axle with a negative-camber situation, the spraddle effect is magnified, resulting in erratic towing behavior and uneven tire wear.

If you want to flip the axle on your camper yourself, have access to a welder, and need saddle mounts, please let us know and we'll see if our mounts match your axle.

Torsion-Bar Lift Kit

Flagstaff's Classic, High Wall, and T-Series use a torsion-bar axle that mounts directs to the frame (the suspension is provided by the rubber torsion action inside the axle). To raise the frame, the axle is temporarily removed and extra mounting plates and full-channel risers are welded to the frame. The risers can be 2", 4", or 6" high, but the most common lift is 4".
