Race Ramps RR-WC-12 12-Inch Wheel Cribs for Cars & Trucks - Heavy Duty Tire Support Ramps for Vehicle Maintenance, Oil Changes & Storage (Set of 2, Fits Tires Up to 12" Wide) - Perfect for DIY Garage Repairs & Auto Care

The first thing most people notice about these Race Ramps is the price. I sure did.After I considered the pain of struggling with cumbersome jack stands since 1970 and never being quite able to comfortably reach the part I'm working on, I realized that it was past time I upgraded.These Race Ramps are worth every penny. They are incredibly lightweight, strong and steady and allow all the room a shade tree mechanic needs.The upper pieces weigh only 2 pounds and 1.4 ounces each.The lower pieces weigh only 2 pounds and 2.4 ounces each.A toddler could easily use these for building blocks.Over the years, I've heard stories about jack stands rocking/shifting under weight and even breaking. These Race Ramps won't shift or break and the crib design keeps the tire from rolling.I saw some 2" x 12" boards crack in half one time and a wheel slam the ground injuring a DIY'er mechanic.This set of Race Ramps RR-WC-8-2 8" Adjustable Wheel Crib is 4 pieces, 2 lowers and 2 uppers.One upper and one lower, stacked together as designed, can be placed under two wheels raising the two wheels 8 inches.One piece can be place under each of four wheels raising the entire vehicle 3.75 inches.Before ordering, you might want to test your vehicle and jack and see exactly how high it will lift your wheels off the floor.Another great feature of these stackable shorter blocks comes into play here. If your jack will not raise your vehicle wheels 8 inches, simply raise it 4 inches. Most all jacks are capable of a 4-inch lift. Place one lower section under the wheels and lower the jack. Place a 4-inch block on the jack plate and raise your vehicle again. Your vehicle wheels will raise a bit over 8 inches above the ground. Add the upper Race Ramp section and lower the jack.Don't jack around with safety. Put your baby in a safe crib and go to work.Made in USA.
