The name DUALLY highlights a buying interest, but a vehicle's name or rear-wheel configuration cannot establish lift fit. When comparing Olympic's 4PXL-10 DUALLY with the 4PHR-9X, the useful starting point is a dimension sheet for each proposed vehicle and a current drawing for each lift.
Compare ratings and runway length first
Olympic's current product pages list the DUALLY at 10,000 pounds of rated capacity and the 4PHR-9X at 9,000 pounds. They list 195-inch runways for the DUALLY and 181-inch runways for the 4PHR-9X. The latter's manual also identifies its 9,000-pound rating and 181-inch runway length.
Those differences can help establish which model deserves further review. They do not replace the manufacturer's limits on vehicle placement, tire support or loading. Never interpret a longer runway as permission to extend beyond the approved support arrangement.
Compare like-for-like width measurements
The DUALLY page lists a 112-inch drive-through width. The 4PHR-9X page lists an 87.67-inch drive-through width and a 112-inch overall width. That repeated number illustrates an easy shopping mistake: the same measurement can describe very different parts of two lifts.
Write the dimension name beside every number in your comparison. Overall width describes the equipment's footprint; drive-through width describes a passage identified on the lift drawing. Neither alone describes the complete path of a truck's mirrors, body, tires or accessories through the bay.
Include the tire-support arrangement
With dual rear wheels, ask Olympic to review the full tire arrangement and permitted runway settings for the exact vehicle. Supply measurements and photographs requested for that review. Avoid relying on an overall body-width figure as a substitute for the location and width of the tires.
The DUALLY product page describes adjustable runway spacing. Ask which dimension is adjustable, what the supplied drawing permits and how that relates to both front and rear tires. Do not infer an adjustment procedure from catalog wording.
Check length with the ramps in place
The garage needs room for the equipment, the approach and the vehicle's path. Compare overall length with ramps, not only the supported runway length. Include the door opening, the area outside the bay and any turning movement necessary to line up.
A lift that fits inside a rectangle on a floor plan may still leave an inconvenient or unsuitable approach. A drawing review should include what happens before the vehicle reaches the lift.
Review high-rise storage as a complete arrangement
The 4PHR-9X is marketed as a high-rise storage and maintenance model. That positioning makes vertical planning important, but the DUALLY also requires the same complete review when another vehicle is parked underneath. Provide both vehicles' dimensions, the intended storage arrangement and all overhead obstructions.
Do not turn a maximum under-runway-clearance figure into an assurance that two named vehicles will stack. Ask for the permissible arrangement to be confirmed against the exact lift and site.
Request a specific recommendation
Send Olympic the vehicle years and configurations, weight information, wheelbases, tire measurements and a bay sketch. Request a quote that identifies the current drawing, manual and included accessories. Call 866-774-4531 to discuss the DUALLY and 4PHR-9X using the same evidence package.
