Finally, a set of ramps that even a low-slung Mazda Miata can drive right up on! Whether you're changing oil or just detailing your undercarriage, these steel ramps provide safety while working underneath your car. The deep side rails help to keep your tires centered on the ramp, and the gradual incline takes the drama out of driving up on them. With 7 1/2" of overall lift of the vehicle, the 9 1/2" wide pair of steel ramps will support 4,000 lbs. of vehicle weight. The extension kit, made from tough ABS polymer, extends the ramp length by 15 inches, allowing maximum clearance for vehicles - even ones with low front ends. Made in the U.S.A. Enjoy safety!
