RockLaurence FSJ Long Travel suspension 4-5" of lift

Post by rocklaurence »

RockLaurence is proud to offer this new FSJ Long Travel Suspension system that provides lift and a softer ride for FSJeeps. Here’s how and why it is the best system for our Jeeps. First, the system uses our Front Spring Shackle Reversal [FSSR] that puts the springs in a position to absorb more of the road forces by allowing the axle to move backwards instead of transferring the force to the frame. Second, our custom springs have 9 leaves and are 56” long. That’s 16% longer than the original 47” springs. This with the FSSR allows the spring to carry the load with far less arch. Note: all Lift Kit manufactures use the original 47” long spring to minimize Customer expense and to fit the original brackets. However, it’s impossible to add more arch and load capacity to a 47” spring and still have a soft ride. Third, to maximize ground clearance and performance we replaced the spring shackle with a Heavy-Duty slider box. Lastly, by Thinking Outside the Box we have developed a system that provides 4-5” of lift, has 8+ inches of front axle travel and rides softer/better than any other kit. No other manufacturer comes close. Note: this kit requires several additional considerations. First, a pocket [included in the kit] will need to be welded into the transmission cross member to account for the extra front axle travel and drive shaft clearance. Second, a long travel front driveshaft and shocks are required but are not included in this kit. I’m currently working to add these parts as options. S&H is subject to your location [estimated at $260 for springs and kit]

As most of you know, I've been working on this for several years. I wanted to make sure that everything worked together as a system. For example: I had to test 3 different sets of springs until we developed a set that would provide the lift needed and would'nt sag. Also, I'm working with Tom Woods, Pro Comp and Go Rancho to provide the front drive shaft and shock options. Until then shocks will have to be sourced by the customer. This is a really comfortable riding system because the springs are 9" longer than the OEM springs and are only arched to provide 2" of lift. The other 3" of lift are provided by the spring brackets and Slider Box. I'll post up more pictures of the kit installed and will post a installation video on YouTube.

Well, I'm 70% finished with the Suspension install on my '81 Cherokee. Everything went together really well and there were only a few small items to change to the kit. The biggest delay for me was learning the New-to-me GoPro. Once I get the video edited and posted Ill provide a link here.

I don't wanna sound like a jerk but if you're going to sell a system you ought to have pics of it; and not just sitting in the parking lot. How's a prospective buyer to know it isn't just a buncha parts?

I see this a lot with aftermarket parts.

Very True. I agree and I hope to get more information out there in the future. These are several reaons that I have failed in this regard. First, I've been working a full time job and doing this [RockLaurence Vintage Auto Parts] on the side and trying to deploy videos to two channels. I've been very busy. Second, I don't have a dedicated offroad FSJ [yet]. My Cherokee will become my daily driver [someday] and I'll only 4 wheel it occassionally. Also, the Shop Truck is just that-a shop truck and won't be Wheeled hard. Third, I'm in Florida and the offroad environment is all sand and swamp. Not a very interesting place to display the attributes of a suspension system. Lastly, I'm semi-retired now and plan to get these vehicles out and into the wild! I'm also anticipating a very unique FSJ build that will be driven often and hard offroad to prove the advantages of our products. Stay tuned :-bd

I'm a suspension geek, I'd crawl around it ;) :D

need to holler at you when I'm in your neck of the country for more than a few hours.
The bus I ride is so short it is a yellow Smart Car full of squirrels, monkeys and clowns.

Finally, I have a complete front Long Travel suspension install video. I'll have a second video on the rear install soon.
