Timbren helper springs July 02, 2003, 09:02:17 am Yahoo Message Number: 24093Anyone have experience with these? I'm looking at installing on a 1989 Chevy 22' RL on the rear only. Have Bilsteins, but am looking to make the ride in the back a little better for the passengers back there. Thanks.

" What is the rear of your LD doing that requires help. Our 83 FL LD's rear suspension would bottom out when heavily loaded and it suffered from a lot of sway. A sway bar and Bilsteins did not cure the problem so I installed Firestone air bags on the real axle. They helped cure the sway and bottoming but it did nothing to 'improve' the ride quality, if anything it was harsher. The air bags are adjustable. The Timbren helper springs are constructed from rubber blocks and offer no adjustments. Timbren type springs are normally found on heavy-duty trucks like dump trucks and street sweepers where ride quality is usually not a consideration (unless you are the driver). Air bags may be a better choice and are more widely available.Larry

Outside of replacing the leaf spring suspension with a different design, there is really nothing you can do that will improve the way it works. The three things you can do are to replace the old, hardened and worn spring bushings, switch to 'D' rated tires instead of 'E', if that is what you have, and run the rear tires ONLY at the recommended pressure for your load - not the max for the tire.A sway bar added to the rear will improve handling, but have little effect on ride. As Larry said, air bags or other 'spring helpers' will only make the ride worse.Steve
Re: Timbren helper springs-Anti Sway Bar Reply #3 – August 18, 2004, 09:28:59 am Yahoo Message Number: 42122A sway bar added to the rear will improve handling, but have little effect on ride. As Larry said, air bags or other 'spring helpers' will only make the ride worse.SteveJust wanted to add that I installed a Hellwig anti-sway bar to our 1989 C30 chassis and I can feel an improvement in the handling. Passing semis on the freeway no longer "push" Big Red, but it's more like a nudge. Same going around curves or over RR tracks. Before, Big Red would rock back and forth a couple of times - now maybe left, right, then back to even. About $170. Bolt on installation in about 30 minutes. One person can do it, but a lot easier with two people.John & Cheryl 1989 22' RL Big Red

Oldest son describes the ride in the back as “not too bad if you are used to riding in the back of a school bus.” I thought about Mor-Ryde, but the $1200 installed cost said, nope, not going there.John A WozniakAnyone have experience with these?
