orion :: SS Posted June 14, 2005 Report Share Posted June 14, 2005 Hey guys... I dunno about you, but since day 1 in my SS, I thought the rear felt VERY bouncy. I thought maybe the rear shocks were blown, but with less than 20,000 miles it was very unlikely - But I decided to pull one off today and check, and they are just fine. While I was underneath there, I noticed the bumpstop was REALLY close to the axle. I always assumed that the SS had a shorter bumpstop due the rear being 2" lower, so I checked the part # (15712438)...looks like the same part for ALL late model Silverados! So I decided to remove it, to see how the ride was... The first bump I hit made it clear that the rear was riding on the bumpstops WAY too much...the ride was SOOOoooo much smoother now. ...which makes sense: If you've ever lowered a car, you ALWAYS cut the bumpstops so the supension travel does not bottom out too early on the bumper. And if/when it does, it bounces uncontrolled, and makes the ride quite sh!tty... So I went ahead and cut ~1" off the bumpstop (I'd have loved to leave it off, but it's important to have some bumpstop, for REALLY big bumps). I must say, I'm happier with my truck now than ever...so much smoother. There's one road by my house with a lot of small bumps (think reverse speed bump, a rut all the way across the road) and before it was rediculous...you'd hit one, the rear would bounce 4-5 times, and you'd almost come off the seat. As soon as it settled, you'd hit another bump just like it! Well, I just drove that road, and it's 300 times better...takes the hit, settles...takes the next hit, settles...just smooth. Anyway, here's a quick how-to: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Jack up the rear of the truck...you don't have to remove the wheels: Reach over the tire and remove the bumpstop...there is only 1 15mm nut holding it on: (FYI, this pic was after I cut the bumpstop) Here's the bumpstop as it comes from GM: I cut it off at the crease, about 1" up from the bottom. This leaves plenty of material for big bumps (keeps the axle from bottoming out): Then reinstall...this is VERY easy, and fast. Took me 10 minutes to remove, cut, and reinstall both sides. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Anyway, I'd highly reccomend you try this, see if it helps your ride. If you think it's an utter failure (it may cause a little more 'sag' with a heavy load)...it's not a costly mistake...these bumpers are only $9 each from GM. Cheap. So, I hope that helps some fellow SSS'ers... Comments, flames, etc...all welcome. - Brian Link to comment Share on other sites More sharing options...

TurbochargedBerserker Posted June 15, 2005 Report Share Posted June 15, 2005 That's funny - I was just bitching about how 'bumpy' my truck feels compared to my wife's truck... Link to comment Share on other sites More sharing options...
2drTahoe Posted June 15, 2005 Report Share Posted June 15, 2005 I've driven several of the new style trucks, they all feel bouncy. I prefer the ride of my old style. I drove one with those push button shocks. The two settings were bouncy and more bouncy, it made me laugh. Link to comment Share on other sites More sharing options...
XGMTech Posted June 15, 2005 Report Share Posted June 15, 2005 I'm game. Maybe I'll try it this weekend. And if I don't like it, it was only a $18 gamble. Link to comment Share on other sites More sharing options...
PewterC3 Posted June 15, 2005 Report Share Posted June 15, 2005 take a closer look. the bump stop is bolted to a stamped steel bracket that is removeable. not only that....but there's even a hole in the frame for the bump stop, including a key hole. just remove the bracket and bolt the bump stop to the frame. no cutting.

WEEZARR1&SS Posted June 15, 2005 Report Share Posted June 15, 2005 Interesting for sure, I will have to try it also. Thanks for the info. Link to comment Share on other sites More sharing options...

TimC3 Posted June 15, 2005 Report Share Posted June 15, 2005 I wonder if this would do any good on mine? I sit about as high as a Z71 anyway.. Am I riding the bumpstops too? Link to comment Share on other sites More sharing options...
j4nash Posted June 15, 2005 Report Share Posted June 15, 2005 I have noticed that on my truck my drive shaft has a rub mark on it and up on the frame. so i think it came from when i pulled our boat. our boat is about 5200lbs. so could that make the drive shaft rub?

Here's a pic of the lifting blocks (they also come on a Z71) and the bump stop extensions. remove it all and save about 12lbs. In this pic you can see the 2" blocks under the leafs (far right): In this one they are gone... and you can see the bump stop mounted directly to the frame: Link to comment Share on other sites More sharing options...
orion :: SS Posted June 16, 2005 Author Report Share Posted June 16, 2005 ^^^ Thanks for the info...maybe a better way to achieve the same thing. Remove the SS bumpstop mount, and relocate the bumpstop directly to the frame. That's give you another ~1.5" of travel before it hit the axle, and smooth the ride in a similar maner to what I did. No cutting required. Good stuff. - Brian Link to comment Share on other sites More sharing options...
superman Posted June 16, 2005 Report Share Posted June 16, 2005 When i lowered mine i did the samething, i also did the front bump stoppers too. Link to comment Share on other sites More sharing options...
ArrivalBlue03 Posted June 16, 2005 Report Share Posted June 16, 2005 I just looked at mine, and the front is riding on the bumpstops! Will this work on the front as well(cutting them down)???? And I don't mean close, it is sitting on them in the driveway! No wonder it feels so tight in the front when I hit a bump. Link to comment Share on other sites More sharing options...
