bumpstop extensions

I just purchased AEV 3" springs, 1.25 BL + 1" MML and Rancho 9000xl shocks and plan on using 33's

What size bumpstops should I use?

Measure distance between spring pad and edge of bumpstop cup (not jounce bumpers). Measure distance from tires to fenders. Measure distance before shocks bottom out. Add bumpstop extensions till first measurement is equal to or less than other two measurements.

Edit: Oh, yeah, also need to check your steering in front at full bump. Depending on where you have axles positioned, what trackbar you are running, what diff cover you are running, etc. you may need more extension to prevent interference there.

every vehicle is different, the only way to tell is to do the work and cycle your suspension

guys ... even though there are so many variations ...

but can't you just tell OP 1.5"-2" BS extension for his 33" with a 1.25 BL and Rancho shocks for 3" lifts should be OK?

The theory ... with 1.25 BL he would clear 33" off his fenders if he uses about 1" BS extensions.
The Rancho shocks are the limiting factor ... and savvy is selling the 2" Currie BS extensions for their 3" and 4" lifts ... with or without BL ... and quite often in conjunction with the right Ranchos. Not so much magic, right?

thats a lot of estimates, they may work, but would not be optimal.

ever wondered why the Currie Bumpstops (equiv 2" extension) are one size fits MOST applications?

Because MOST shocks for 3"-4" lifts need this much for protection (as well as MOST aftermarket adjustable front track bars need this much to clear front diff cover).

All coincidence ...

If you keep the shock mounts stock there is not much more uptravel to gain ... maybe 0.5" (with a very limited number of 10" travel shocks).

And 33" tires under stock fenders are just fine with 2" BS extension ... with or without BL.
