I removed the blocks on my 2019 Single Cab.

I’m looking at new rear shocks.

There are different part numbers for Bilstein 4600s for 2X4 and 4X4 so I assume they are different in some way.

So with the blocks removed isn’t my truck essentially a 2X4 suspension wise?

Yes, the 2WD shocks will be the better option with the rear blocks removed.

I removed the blocks on my 4WD and did some research on this. I ended up going with the 2WD version of Fox shocks and they work great.

The 4WD versions will still be ok, but 2WD versions will be compressed a bit less and therefore have more of the intended performance.

Are you are going to be adding something to the rear axle to help prevent squat, such as air bags or RAS? If so, then you would want to stick with the 4x4 shock part number as those will raise the back end back up to stock-ish height. This is the set up I run on my truck. If you are going for just a rear drop, get the 2wd shock like mentioned above. Don't forget to adjust your headlights, as they will be aiming higher after a rear drop.

aquaman67/CJW91,
I'm looking for a set of the stock rear blocks and mounting hardware so I don't suppose you're looking to get rid of stock ones are you?

Thank you

CJW91

I got rid of mine (although should have kept them haha since I think I may want to add back the blocks and add a level at some point in the next few year).

aquaman67

Thanks for the info everyone. I’m not sure which brand I’ll go with.

I’m waiting to hear back from Eibach.

r8ders, PM sent.

Not terribly expensive... considering this comes with the U-bolts you'll need.

Unless I’m reading your post wrong, I don’t think this is true. The 4x4 rear shocks should have zero impact on the ride height of the rear of the truck.

As mentioned CJW91, the shocks will just be compressed more.

Yeah, shocks do not determine ride height......

correct, rear shocks don't control ride height. The size and position of the rear spring, paired with the spring rate do. If you take out the rear block it will drop the rear 1.25". If you add something back in to the mix that lifts the truck to back stock ride height, such as a helper spring, almost deflated air bag, or a road active suspension spring... you will want to go with the 4x4 shock.

Ex... I wanted to add RAS to my truck, but I didn't want the truck to be 1.5" higher in the rear when unloaded. So I removed the rear block, cranked the RAS to almost the 2mm setting, and swapped my stock 4x4 shock for a 5100 4x4 shock. Stock ride height, increased spring rate. Removing the rear block also reduces axle wrap... paired with the RAS virtually eliminates it.
