When it comes to lifting the rear of your truck, the difference between a 2" and a 3" block might seem minimal, but that extra inch changes more than you’d think. Whether you’re chasing a leveled look, compensating for load sag, or building out your truck’s stance for function and form, choosing the right height is key.
Here’s a breakdown of how to decide what works best for you!
What Rear Lift Blocks Actually Do
Let’s start with the basics: rear lift blocks are placed between your leaf spring and axle to increase ride height without affecting your factory ride quality. They’re a clean, bolt-on solution that keeps your OEM suspension geometry intact.
Unlike full suspension lifts, blocks are a purely vertical lift, nothing more, nothing less. That makes them ideal for trucks that:
-
Are already lifted in the front
-
Need to level out a nose-up rake
-
Or want to restore height lost from hauling or towing
2" Rear Blocks: Subtle, Balanced, Level
A 2" block is the go-to choice for:
-
Leveling out a lifted front end (especially if you have a 2" to 3" front lift already)
-
Maintaining OEM-style ride quality while evening out the stance
-
Daily drivers or trucks with light weekend duty (camping gear, light towing)
Why go 2"?
-
Keeps a clean, factory-adjacent profile
-
Less strain on shocks and driveline angles
-
Still gives you noticeable clearance and stance improvement
Best for: Aesthetic balance, daily driving, mild trail use, or if you already have a front lift and want to dial in the rear just right.
3" Rear Blocks: More Stance, More Load Support
A 3" block steps things up. This height is ideal for:
-
Trucks with heavier rear-end loads (work trucks, overlanding builds, or toy haulers)
-
People who want a slightly raked look for that aggressive, ready-to-haul stance
-
Creating more tire clearance for a future rear tire upgrade
Why go 3"?
-
Adds a more noticeable lift without a full rear suspension swap
-
Helps fight rear-end squat under payload or towing
-
Matches better with taller front lifts (like 3.5"+)
Best for: Work trucks, lifted rigs running heavy setups, or anyone who prefers a classic raked profile.
What Else to Consider
U-Bolt Fitment:
Make sure your U-bolts are long enough to accommodate the added block height. At Reaper Offroad, our kits come with correctly sized hardware for your selected block.
Shock Travel:
While most trucks tolerate a 2–3” lift in the rear without shock changes, always check your travel limits if you’re pushing the truck off-road or towing heavy.
Aesthetics vs. Function:
A 2” block looks level. A 3” block looks mean. Decide whether your truck needs balance or dominance.
The Reaper Offroad Lifts Take
At Reaper Offroad Lifts, we don’t offer a dozen random sizes for a reason, we’ve seen what works. Our 2" and 3" rear lift blocks are designed for trucks that need a clean, reliable lift without overdoing it.
If you want to fine-tune your stance, compensate for sag, or maximize function, it all starts with picking the right block! Still not sure which height fits your build? Check out our lift kits with all the fitment information you need to ensure compatibility!
