Broken Roush 4x4 leaf spring 05
So Flt, Does this mean you running back at stock ride height? Or did you replace the complete kit with another? Ive been Thinking of upgradeing my shocks, possibly to some Bilstiens but Ill have to find the correct P/N , so that they work well with the Drop. Im thinking that somehow they gave you the wrong struts, like one meant for stock ride height, and thats what may have caused the breakage. I have set of Roush struts for my stock spring set up as well. Never had a problem with those either. Older Roush shocks and struts were made by Bilstein. But the name that that is one both sets of mine is Sachs. Also the end links in the Roush kit are Ford 4x2 end links to make up for the loss of 2 " of spring. I got that info directly from Roush when I recieved the incorrect swaybar for my application, there was a mid year change in swaybar style ,which affects the links. Roush swapped me for the correct bar no problems. Great customer service.
I got my Hellwig rear bar of ebay used, lightly used. the guy was trading his truck in so he removed the extras. Ive got it off right now. Because I wanted to get the baseline feel of the Roush kit and what it did for handling. There is a little issue with clearance between the left side tailpipe and the endlink that I need to adress. I had to compromise the direction of my exhaust tips slightly to prevent having a rattle. When I put it back on (soon), I'll do what ever I have to do to make it right. New rear springs going on today, Im just waiting for the call to pick it up. I just had some surgery so I cant lift anything right now. Otherwise I would have done it myself. Look at stage three motorsports, or roush overstock. I used the Drop shackle that was made for the Roush Nightmare. You can pick up a pair cheap, like $45. They look great, and are greasable. There are two positions on them . 1" or 2" . Im just doing 1" because I have the 3" drop springs.
Whats strange to me is that the GF. shackles come with shims, and the Roush do not. I called Roush and asked about using the Nightmare shackles with their suspension kit. and weather or not shims were needed, because none were included with the suspension kit or with the shackles. They assured me I didnt need any shims, what I was doing was exactly what they did it in their nightmare truck. So I havent detected any driveline vibrations , so I guess Im OK.
I just happened on this thread. I also have the Roush suspension on my 07 Harley 2wd truck. Both of my rear springs broke on my truck--well, the short/overload spring on each springpack cracked in half. I also have lowering shackles and was wondering if these contributed to my springs breaking. I also rarely have a load in my truck, but I do drive it fairly aggressively. Like what was said earlier, I enjoy seeing the look on people's faces when I take a corner at the same speed as sporty cars...
Yup, It wasnt the overload spring on mine, it was one further up . But not the main leaf. Yeah love the cornering when some D. bag is trying to tailgate me and I just walk away from them. Its all fixed now. I too have the lowering shackles. There may be something to that. Did you install any degree shims ?
No, I don't have any shims, but I don't have any driveline vibration at all (that I can discern). I was wondering if the drop shackles added additional leverage on one side of the spring, or something. It was weird because the passenger side broke on one day, and the driver side broke one week later. I actually removed the broken leaves and have been driving around as-is. I thought about putting my stock leaves back in, but I don't want the raked look on my truck--and all this rain is making me feel lazy...
I can concur with quality issues. Roush & Hellwig both...Roush uses Deaver in Santa Ana and hellwig is in Visalia.....nice people but if you visit the shops, well, what can I say.
I ended up designing and building my own. Addco said it couldn't be done/wouldn't work. I basically purchased 3/4" chrome moly (solid) bar, built my own end links and mounting plate that attached to the lower shock mounts, then transvered the bar to the outside of the frame, then run horizontally aboave the frame/under the bed.
this does a couple of things....it allows the use of a bar that is 50% smaller than helwig or Rouch uses....why, because we gain an incredible leverage advantage on the truck by using the frame itself to be the fulcrum point (just like the cars of the 60's), secondly, the aftermarket bars hang below the axle.....what a great "Hook" set-up for grabbing/hanging on anything and everything you drive over and 3rd, 100% elimination of any interferrence with the exhaust system. the result...
well I went down to show John Hotchkis Jr (Hotchkis Suspension), whose father and my dad knew each other from way back in the day's of flatheads, what we had done. We took my Markt LT out for a "test" drive....when I pulled a left hand turn at 30 mph, it took joh by surprise shoving his face (literally) into the passenger door window.....when we got back to his shop, he put it on the rack because i really think he could believe it still had the oem shocks.....even his engineers were called out to see, touch and feel....and couldn't believe the performance.
Persoanlly, i have set up a salom course with my neighbor who had a Porsch Cayenne (non-supercharged SUV)....and I consistantly outran him by 1 mph, and was similiarly demonstrated to the staff at Galpin Motorsports, who again concurred and could not believe what the single addition gave. It is really just a matter of proper design, nothing more or less...and IMHO, much of the engineering from many of the "High Profile" suspension people are, well, CAD designed by recent graduates with no supervision or oversight functioning strictly off "book knowledge".....which don't get me wrong, there is nothing wrong with book knowledge, but, practical experience plays a very important part of successfull design.
Just an FYI...IBACH in Corona Calif, builds many of the "better" suspension parts for the Known Labels" such as Hotchkis....and you can buy direct from them as well.
