ICON RXT leaf spring kit

I'm looking at getting ICON leaf spring and they recommend their RXT rear shocks as well. It is my daily, primary driver and may take it on forest service road once a month. I'm upgrading leaf because camper trailer and intermittently haul heavy loads for various projects. My question is: do I need their bump stop kit along with it? If it is recommended, what is primary purpose of bump stop?

 

Primary purpose of a bump stop is so you don’t compress your shocks so much they blow out the top. Look at it like a last line of defense so your leaf springs don’t smash your frame. I think Icon only makes a hydraulic bump stop and those certainly are not worth it for your style of driving. I would however look into after market bump stops for sure. Those stock rear bump stops suck and when you lift your truck and put in after market shocks a lot of time you’ll bottom out your shock before you hit the stock bump stop. Look into @AccuTune Offroad U-bolt flip kit with bump stop. You look at their chart and they’ll set you up with the correct bump stop spacer and bump stop for your exact shocks and leaf pack, plus you get a flip kit out of it. I have a set and I highly recommended them.

 

Very helpful, thank you! I do not see spacer recommendation for ICON RXT 2.5 shocks on Accutune offroad website. I assume I would just call them to ask their recommendation

 

I have the RXTs on the way and plan on running these. Timbren ABSTRFK Bump Stop

$317 Timbren ABSTRFK Bump Stop

edit: looking at the Accustops, I may end up going that way instead.

 

Icon stage 8 with the RXT leaf pack and 2.5"RR extended shocks... went with Timbren bump stops.

 

No you don't need it, for your style of driving the factory bump stops would be just fine. Air bags may suite your needs better.

I think it's the other way around, the primary purpose of bump stops is to prevent metal on metal contact from the leaf springs hitting the frame, then secondly to prevent the shock from fully bottoming out.

 

Spacer length is determined by the shocks compressed length and your leaf pack thickness. We dont sell Icon shocks, but we can work with you on the correct length needed. Send over a message or you can contact our sales team

 

Any reason you went with 2.5 RRs over the 2?

I ended up deciding on 2s (mostly because I’m “cheap” lol). I got 2.5s RRs up front though.

 

Mainly because they're recommended for the RXT leaf pack and they were included in Stage 8... they match the 2.5" up front.

 

Based on everyone's input here, I called Accutune to discuss my needs for a potential bumpstop for my usage of a heavy load once in a while. They were straight up honest with me and I have to admit....a refreshing opinion based on experience.
They asked my current setup and needs. Discussed weight needs and long term use. End result is that I don't need an aftermarket bumpstop. And, they even made recommendations on which stage of leaf spring I should use.
Many sellers are profit driven for obvious reasons, but I really, really appreciate the honest assessment and suggestion. In the future Accutune has my business for this!

 

I really appreciate you posting this, I have RXTs installed (w/Bilstein 5160’s), little different situation because I don’t carry weight in the back and went with Option 1. However I still worry now and again that I should have upgraded the bump stops.

I’ve also considered air bags only because I tow a boat locally with a 500 ish pound tongue weight and it definitely sags the rear end of the truck when hooked up.

 

What stage did they recommend? How much weight do you have on daily basis?

 

I have an overland setup (pic below). They recommended a stage 1 for my usage to start and stage 2 if I plan heavier loads. They said stage 3 would be overkill and way stiff.

 

What all are you carrying? Hard to tell if you have a RTT or not.

I had debated not getting upgraded bump stops but I figured I needed/wanted a U bolt flip kit anyways and figured I’d be safer than needed so I bought some Timbrens anyways.
