Question:
Do you offer U-bolt for a square tube? Housing axle for your leopard add-on shock system
asked by: Rick
Expert Reply:
Hi Rick; the Lippert Bolt-On Shock Kit # LC281255 is only designed to fit 2-3/8" round axles. There are no U-bolts that can be used to mount them on a square axle. The same is true for other shock kits we carry. Instead, I recommend adding the SumoSprings Trailer Helper Springs. These will help absorb road shock to smooth out your ride and also prevent sway. If you have overslung axles (leaf springs on top of axle) you need # TSS-107-40 and for underslung # TSS-106-40.
