88-98 Chevy 4.5" Rear Shackle Flip Kit

1988-1998 Chevy/GMC Rear Shackle Flip Kit boasts smoother suspension and adds 4.5” of lift to your rear. The kit fits trucks with 63” rear springs and can fit SUV’s (Blazer, Tahoe and Suburban) if new holes are drilled to mount the brackets. Unlike conventional kits, we have added two additional mounting holes at the bottom of the frame to prevent bending and fatigue.


  • Two brackets to position shackles in the downward position
  • 1/2 inch mounting bolts, SAE flat washers and nylock nuts

Easy install, uses factory rivet locations
Compare our design to others, they are not even close. These weigh 30 pounds a pair!

Extreme duty 1/4 and 3/16ths steel.

Laser cut, CNC formed, Mig welded 100% USA made materials and labor, no cheap off shore steel here!

Remove old factory brackets by removing rivets, typically by using a plasma cutter or grinder to remove the head and then punching it out with either an air chisel or a hammer and chisel. Drill the holes out to 1/2" or drill new holes if needed. Bolt to the frame with provided hardware and torque according to fastener torque chart.

Note: Short bed trailer hitch mounting may interfere.

Does not fit the truck

Orders these brackets, looked great. Cut the old brackets off drilled my holes and nothing lines up or fits.

Hello, if you have an 88-98 GMT400 truck these should fit just fine. If you have an 88-91 Square Body truck you would need the 73-87 Rear Flip Kit. We're happy to help troubleshoot fitment issues. Just shoot us an email with some pictures at orders@skysoffroaddesign.com
Thank you,
