Race Ramps Hook Nose Rack Ramps for Lifts and Service Platforms

Because it is much shorter. The 4 inch is 34 inches long and climbs at 8 degrees. The 5 inch is 48 inches and climbs at 6.4. More length beats less height when the question is whether the nose of the car clears.

Nothing bolts or clips. The hook is a shaped 3 inch section at the top of the ramp that engages the runway so the ramp cannot creep forward as the tire climbs. Set the ramps in line with the wheels and seat the hook before driving on.

Only for tires over 12 inches. It is the same 5 inch lift and the same 6.4 degree approach as the standard 5 inch, on a 20 inch deck rated to 18 inch tires. If nothing in the shop runs that wide, the narrower one does the same job for less.

If the runways are the same height, yes, and at these weights carrying a pair between bays is trivial. Different runway heights need different ramps, because the hook has to meet the deck rather than sit above or below it.
