I ordered a 2" budget boost from eBay top gun customs and includes shocks and the spacers but no bump stop extensions I plan on running with sway bars and not any hard trails will it be ok without them

You'll be fine with that size lift and up to 32" tires. I ran that way back in the late nineties and my lack of bump stop extensions didn't cause any problem.

Jerry, you're wrong. You were just lucky you didn't have the problem this guy did...Help fast! Rear Spring Fell Out

Bumpstop extensions REQUIRED with a budget boost, especially in the rear. Otherwise the spring has no room to compress. I'm surprised you would provide such a terrible recommendation.

If I was going to run a BB, I would also add a 1" bumpstop extension in front (bolted to spring pad), since the factory coils are near coil bind once you add the BB spacer and eliminate the front space for them to compress.

I would also add adjustable sway bar links in front, and make sure to check full droop at full lock, to see if the brake lines are taut and need to be longer. YJ lines are longer and a cheap replacement.

Jerry, you're wrong.

Well thank you for your opinion, it was totally expected. My personal experience is as I stated it. No problems, it worked fine FOR ME. I know you're a fanatic about bump stops but I am not as concerned with that as you are with a simple 2" BB. Yes I have proper bump stops for my 4" lift but not many bother to add to their bump stop length with only a 2" BB and smaller tires like the 32". Do the math on upward travel with a 2" taller lift with a tire that only has a 1" taller radius like the 32" I suggested.

I'm glad you didn't have any problems in your case, but I'm not willing to recommend a poor suspension setup that may leave someone with significant problems down the road, especially when those problems could have been prevented for less than the cost of lunch at Red Robin.

there's a lot more to proper bumpstops than tire size.

 

[Jerry Bransford]

Whatever you say, Bump stops are indeed important, but with some lift and tire size combinations more than others. I'm just not one to go overboard on this subject as some I know where a basic 2" BB and a reasonable size tire is concerned.

My present TJ with its 4" lift and 35" tires where I'd be crazy to run stock bump stops.

My previous TJ back in about 1998 with 2" lift and 32" tires. Stock bump stops and no problems.

It doesn't matter if you've got a stock suspension, 2" BB, 4" long arm lift or a custom mid-arm with coil-overs, you still want a properly functioning suspension.

As I said before, I'm glad you didn't have any problems with your particular setup back in 1998....but knowledge of the TJ series has improved since then, and I will not recommend a poor suspension setup that has demonstrated the possibility for significant problems.

Haha, sounds like husband and wife of the forum bickering, I don't dare say who is who,lol.

It's pretty simple actually. He's recommending a poor functioning suspension setup that can lead to significant problems, I'm calling him out on it. I doubt he's trying to deliberately deceive people, he just doesn't have a good understanding of what bumpstop extensions do when related to suspension mechanics....which is evidenced by his focus on tire size in this discussion. People didn't know any better back in 1998, and the same can be said for lots of other things related to TJ suspension, like poly bushing fixed length control arms, track bars with clearance issues, dual stabilizers, and more. But knowledge has evolved since then, and we learn...normally anyway.

Proper bumpstop extensions for your 2" BB won't cost more than $20, unless you have to replace your OEM jounce bumpers. Two 2" OD x 2" tall body lift pucks for the rear, with longer bolts from the hardware store, is all you really need to prevent coil bind & other issues in the rear. They run about ~$3 each on Ebay.

 

[Spud100]

The OP states he's not going to disconnect and not run hard trails so binding or losing a coil is unlikely. Sounds like a mild wheeler so he's probably ok. Once the OP changes the equation by disconnecting, running more difficult trails and larger tires, the answer to his question changes.

 

[Ironhead Jed]

wouldnt shock length play a large factor as well?

not all shocks with a 2" BB have the same specifications, neither do the shocks for all 4" kits.

i think people focus too much on tire size and lift height and ignore the shocks

 

[Steeljag]

Right or wrong, I don't know.......but, I ran my BDS 2" suspension lift with 32" tires without bump stops without any issues. Granted that Jeep was used for the beaches and mild off roading here in Fl.

 

[gomerkfx700]

Well that was a can of worms I opened and I see the point of both posters. I personally think I will be fine but I am going to try and find 4 hockey pucks and epoxy them to the bottom spring Perch I believe that would do the trick gain a little more flex but should stop it from spitting out a spring if I was to get carried away on a hold my beer watch this moment.

Hockey pucks won't stay in place long when held by epoxy, no matter how careful you are when epoxying them. I tried that several times many years ago and they would fall off within a trail or two. When you need longer bump stops, get the real thing.

Exactly. For someone doing a more serious build for something beyond the level the OP described, I would have included longer bump stops as required.

Jerry, please explain exactly how an anti-sway bar works as a substitute for bumpstops?

In my experience, a 32" tire will need about 1.5" extension of the from bump-stop and the rear will need about 1" (can vary from Jeep to Jeep). The Zone kit comes with extensions that are a bit long and they can be cut down to size. With such a short extension in the front, you will be fine bolting it between the bumps-stop and the tower.

I ran the Skyjacker 2" budget boost, which comes with 1" extensions all the way around, and it was perfect for keeping the 31" tires out of the fenders.
