RhinoGear advertises its RhinoRamps at up to 16,000 lb GVW capacity, which sounds like the number that decides whether a ramp works for your car. It isn’t. Most standard ramps, RhinoGear’s included, use a roughly 17° incline angle — steep enough that a lowered sedan or a sports car with a front splitter will scrape its bumper trying to climb on, long before the weight rating is ever tested.
This guide covers which car ramps are worth buying for an oil change, and why the angle printed in small type matters more than the weight capacity printed in large type. If your car sits too low for ramps at all, our low-profile air bag jack guide covers the same ground-clearance problem from the jack side instead.
Key Takeaways
- Standard ramps commonly use a 15–17° incline angle; low-profile ramps built for lowered cars use roughly 6.8–8°, achieved by making the ramp 2–3 feet longer for the same lift height.
- Weight ratings are usually quoted as GVW capacity for the pair, not per individual ramp — check which figure you’re reading, since some listings show both a lower per-ramp number and a higher per-pair number.
- Ramps only lift the end of the car they’re under. Wheel chocks behind the wheels still on the ground are a standard safety step, not an optional extra, since nothing else stops the car from rolling backward off the ramps.
- Ramps are rated for hard, level, smooth surfaces only — gravel, grass, or a sloped driveway change the safety math the manufacturer’s rating assumes.
The Ramps Worth Buying
RhinoGear RhinoRamps (11909) / RhinoRamps MAX (11912)
RhinoGear’s standard RhinoRamps carry a 12,000 lb GVW rating, and the MAX version steps up to 16,000 lb GVW, both at a 6-3/8″ lift height with a roughly 17° incline and a CoreTrac non-skid base (RhinoGear, retrieved 2026-07-30). They’re rated for tires up to 9 inches wide and nest flat for storage.
Best for: sedans, crossovers, and trucks with normal ride height, where the 17° angle isn’t a clearance problem.
Race Ramps RR-40
Race Ramps builds its RR-series from a lightweight composite rather than the resin/plastic construction common on budget ramps, with a gentler slope specifically aimed at sports cars and vehicles with a short front overhang. The RR-40 and similar low-profile models trade some raw weight capacity for a shallower climb angle that clears splitters and low front bumpers.
Best for: lowered cars, sports cars, and anything with a front splitter or air dam that a standard 17° ramp would catch on.
Approach Angle Decides Fitment Before Weight Rating Does
Standard ramps run in the 15–20° range. Low-profile ramps built for lowered vehicles run roughly 6.8–8°, and the way they achieve that shallower climb is by making the ramp itself 2–3 feet longer for the same total lift height — more distance to gain the same rise means a gentler slope.
If your car sits low enough that a curb cut or a steep driveway apron already worries you, assume a standard ramp will be a problem and go straight to a low-profile design. The weight rating on either ramp is irrelevant if the bumper hits the ramp face before the tire ever gets on it.
GVW Rating Is Usually Per Pair, Not Per Ramp
| Spec as listed | What it actually means |
|---|---|
| “12,000 lb GVW” | Maximum total vehicle weight the pair is rated to support, not 12,000 lb per ramp |
| “3,250 lb per ramp / 6,500 lb per pair” | A working-load figure some manufacturers list both ways — read which number is quoted before comparing brands |
Comparing a “16,000 lb” ramp to a “3,250 lb” ramp isn’t necessarily comparing a stronger ramp to a weaker one — check whether each figure is a per-ramp or per-pair rating before assuming one brand is dramatically overbuilt against another.
The Safety Step Most Buyers Skip
Ramps only support the end of the vehicle actually sitting on them. Nothing about the ramp itself stops the car from rolling backward off them, which is exactly what wheel chocks behind the wheels still on the ground are for — this is a standard, expected step, not extra caution for the nervous. Set the parking brake and chock the far wheels before you get anywhere near the oil drain plug.
Manufacturers also rate these ramps for hard, level, smooth surfaces only. Gravel, grass, and any meaningful driveway slope all change the friction and stability assumptions the weight rating is built around — move to level pavement rather than trusting a ramp on a surface it wasn’t rated for.
Frequently Asked Questions
What incline angle do I need for a lowered car?
Low-profile ramps built for lowered vehicles run roughly 6.8–8°, achieved by making the ramp 2–3 feet longer than a standard ramp for the same lift height. Standard ramps in the 15–20° range are likely to catch a low front bumper or splitter.
Is the weight rating on car ramps per ramp or per pair?
It varies by listing. Some manufacturers quote GVW capacity for the pair together; others list a lower per-ramp figure alongside a higher per-pair figure. Check which one you’re reading before comparing brands on weight capacity alone.
Do I need wheel chocks with car ramps?
Yes. Ramps only support the wheels resting on them; chocking the wheels still on the ground is a standard safety step to prevent the vehicle rolling backward once the front end is elevated.
Can I use car ramps on gravel or a sloped driveway?
No. Manufacturers rate these ramps for hard, level, smooth surfaces only. A gravel surface or a meaningful slope changes the stability the rated capacity assumes.
How much weight can standard car ramps hold?
RhinoGear’s standard RhinoRamps are rated to 12,000 lb GVW, and the RhinoRamps MAX version steps up to 16,000 lb GVW — both figures for the pair, covering the vast majority of passenger vehicles and light trucks.
The Bottom Line
Buy the RhinoGear RhinoRamps or RhinoRamps MAX for a normal-height sedan, crossover, or truck — the 17° angle and 12,000–16,000 lb GVW rating cover that use case comfortably. Buy the Race Ramps RR-40 or another low-profile design if your car sits low enough that a splitter or front lip is a real concern. Either way, chock the wheels still on the ground, confirm you’re on hard level pavement, and check whether the weight rating you’re reading is per ramp or per pair before assuming one product is stronger than another.
