Body Lift or Suspension Lift: What’s the Difference?
There are essentially two ways to lift your 4WD vehicle and they are suspension lift and body lift. Each method has its pros and cons which most often involve price, performance, and ease of installation. Before going further, let’s first distinguish between the two.
A suspension lift raises the vehicle’s frame (chassis) away from the ground. This can be accomplished in a variety of ways such as installing taller springs or spring spacers, differential drop brackets, lift blocks, cranked up torsion bars, or any combination thereof.
A body lift raises the vehicle by lifting the body away from the frame with spacers. The frame hasn’t gained any clearance from the ground.
A suspension lift is recommended for anyone planning to use their vehicle off-road while a body lift is recommended for anyone that wants to make their vehicle look lifted without the real desire of ever driving off-road. Is this to say a body lifted vehicle can’t go off-road? No. It’s perfectly capable of going off-road. It just won’t perform as well as a suspension lifted vehicle because it hasn’t gained any ground clearance.
Suspension lifts are most often made between 2-inches to 6-inches, while body lifts range between 1-inch to 3-inches.
A suspension lift is more complicated than a body lift because it alters all of the suspension components that give the vehicle its factory ride characteristics. Installing springs that generate lift will have a harsher ride quality than with soft factory springs. Longer shock absorbers will be needed. The vehicle will also have a higher center of gravity because the entire weight of the vehicle (everything except the axles) will now be raised further from the ground. In some cases, the transfer case will need to be lowered and the rear differential repositioned to minimize driveline vibrations as the Jeep Wrangler is notorious for having a short rear driveline that isn’t readily accepting to increased u-joint angles.
Pros: Increases ground clearance, increased approach and departure angles, allows fitment of larger tires.
Cons: Costs more, longer installation time, driveline angles are increased (more likely to vibrate), brake lines need to be re-routed or lengthened, new shocks needed, increased center of gravity.
A body lift is relatively simple in that it primarily consists of a set of spacers that are inserted at the mounting points between the frame and body of the vehicle. This leaves all the heavy parts of the vehicle (frame, engine, transmission, transfer case, etc) at their factory locations so the vehicle’s center of gravity (though increased) will not be increased as much as a suspension lift.
Pros: Inexpensive, can be installed quickly with basic hand tools, allows fitment of taller tires, simpler (all parts necessary come in a small box).
Cons: Appearance (a gap between the body tub and the frame will now be visible), extra leverage is placed on the mounting points (this is especially true for higher lifts), no increase in ground clearance.
Ultimately, a body lift provides no benefits other than allowing the installation of larger tires whereas a suspension lift is designed for improved performance off-road (while also allowing the installation of larger tires). If you’re on a budget and want to make your 4WD look like a tough off-road vehicle but have no real intentions of ever going off-road, then a body lift would be adequate for you. However, if cost isn’t a factor and you’re looking to make your 4WD more off-road capable and trail ready, then a suspension lift is highly recommended.
Now that you’ve been educated on the differences of suspension lifts and body lifts, you might want to visit MY4BY OFF ROAD and browse their ever-growing inventory of off-road parts and decide for yourself what type of lift is best for you and your driving needs.
