SS944
2” Spacer Kit for 2x4 Frames
The SS944 frame riser kit is designed to t both 2x3 and 2x4 boat trailer frames. The spacer tubes t between the bottom of the frame and
the spring brackets. This allows the frame and its support system can be raised 2” with respect to the axle and fenders for boat designs
requiring additional fender clearance.
The riser tubes are designed to t the spring brackets for both the 13” and 14” tires. The kit includes the correct length U-bolts for either
size frame.

INSTALLATION INSTRUCTIONS
1. Break the bundle and sort all items by size.
2. Loosen and remove the U-bolts attaching the spring brackets of
the trailer to the side frames.
3. Raise the frame up until the spacer tubes can be inserted between the side frame of the trailer and the spring brackets.
4. Align the holes of the frame riser with the holes in the spring
bracket. Note that the frame risers have two sets of mounting
holes in the brackets welded to the riser tubes. If the frame risers are being installed on a trailer with 13” tires, align the inner pair of holes with the spring bracket. The outer most pair of
holes will align with the 14” spring brackets.
5. The kit includes two new length U-bolts for either the 3” or 4” side
frames. Insert the appropriate length U-bolts into the aligned
holes. Place on the new ½” ange lock nuts provided. Tighten.
Assembly is complete.
