I have a 2014 JKU with a 3in suspension lift. I'm adding a 1.25 Rough Country body lift. Do I need a motor mount too? The couple of threads I found about it didn't give much info. I just want to make sure I get everything I need because I plan on ordering it today.
And to answer the question 'why a body lift'...well, just because I want to. I have 35 tires & after I saw it with the 3in lift, I wanted to add just a little more. Right now it's being used as my DD. Not any hard off-roading just yet.
Well let me answer your original question since my first post didnt. No, you shouldn't need new motor mounts as you're just shifting the body up but the drivetrain will stay where it is
A puck is just a budget boost lift. You can buy a 1,2 or 3" set on amazon for just over $100. What it does is fits on top of the spring around the bump stop and essentially pushes the spring downwards. Many people do these on stock rigs to add some height. The benefit is that this is an actual lift. A body lift raises just the body. This can sometimes make shifting linkages and other wires stretch and cause complications. It also does absolutely nothing for function. Your differentials, oil pan and other things are still just the same height, but now your body is higher. If you've seen a jeep with a body lift it leaves a gap at the front at the bottom of the grill and in the back by the bumper, as the bumpers won't move with a body lift. Personally I can't stop staring at those gaps and the lift is very evident and not in a good way. It will give you more space or allow you to run larger tires tho.
With the puck or budget boost you'll increase the ground clearance of your oil pan and drive train. Your axles will stay the same height as those are determined by your tire height. Similarly, you'll get the larger gap in between the wheels and the fenders you're searching for without the weird bumper gap.
The biggest reason to do a puck for me is ease of installation. I've never done a budget boost but I can't imagine raising a body is easy without a fork lift or some other hoist to lift up the body. Then there is the worry about snagging wires or linkages. A budget boost is very easy to do in your driveway. Just drop the axles, pull the coils, add puck and put back together. Then probably adjust control arms
Modifying any vehicle CAN cause problems. The chances of problems are lower with a suspension lift like a coil or puck lift
My husband pointed that out to me last night. Adding a puck lift would just be like getting a 4jn suspension lift instead of a 3. We went with a 3in to stay away from having to change anything else, drive shaft, etc. Getting the body lift we wouldn't have to do any of that, right? But we talked about maybe holding off on the lift & looking into new fenders. That may give me more of the look I want.
As for the motor mounts, you could be thinking about a MML, only TJ, YJ, XJ use them. No such thing for a JK. I've done 3 JK's BL, all 1.25'' not one had a problem after the install.
Your husband & Ruby Tuesday are right in their thinking. With a short lift and a body lift none of those problems come in to play. Now do you need a BL to run larger tires,, no. It's up to you how you want your jeep set up. But I will say with a 3'' lift ,1.25 BL and flat fenders 35''s might look small to you with that set up.
Do the BL first then see how it looks to you with the 35''s
