"It'd be alot cooler if you did"
Never had any issues using a hi lift on my round tube sliders on my 4R.They all look nice, but I prefer rectangular tube to round in case I need to use High Lift jack on them. Round will kick out easier than rectangular. For me rectangular is more functional.
But for anyone that is nervous, they make a tube "gripping" attachment for the hi-lift.
