    Make sure im right. Start dropping lf till spring barely unloads and chain or 1inch extension on shock from ride height? Good starting point?

      Personally if your wanting to try it and looking for a ball park starting spot on how much to change travel, I'd shorten the travel on the LF a 1/2" from where you are now (where the shock stops it). That won't be totally radical change and should give you an idea of what it does for you, unless the LF is staying down by it's self for the most part then you can go a more. Basically I'd shorten about a 1/2" from where you're seeing your rebound travel typically at on your cars approximate rebound travel if it isn't coming up all the way.

          My device basicly had it limited just about when the spring dis-engaged the shock collar.

          I took it off all together, going to see what it does off, and then i will try what MB and Billet says, about a 1/2" before the shock tops out.

          Just say no...

            In case I wasn't clear, my post was to limit travel a 1/2" from what your getting if you wasn't tethering the LF at all and you was wanting to try it as money17 asked. Now with that being said: The actual point that you end up stopping it at will vary greatly between drivers, car, tracks, set ups, and etc.

            You may end up anything from full droop the shock will allow to tethered almost at ride hieght, that's a huge range but there isn't a set dimension that works for everyone. Also keep in mind that the shorter you go, you may need to alter the car's set up to actually make use of it. It like anything has pluses and negatives for different situations.

            Just wanted to be clear that what I posted wasn't being taken as that is the most general length that is used, just where I'd start and adjust from there and fix any issues that come up.

            Also want to add that stopping it when the spring unloads which is fine, but not for comparative purposes. Even with the same brand of car, one may have a stiff LF and one may have a soft LF or have different wheel loads cause of left side weight or wedge, so one may extend 1" before unloading the spring (say stiff LF or low Left side % car) and the other car (soft LF or high left % car) may extend 2" to unload the spring from ride hieght. IMO it's better to look at travel from ride hieght and use that for comparison numbers, because obviously 1" to 2" is a big difference in tether length.

              Tops out may of been the wrong word, 1/2" from full droop or shock's max extension.

              Currently were running high left-side % 54.5, and rear % is high as well, 55.5 or so. That's with 100 lbs of bite and a 500 lb LF spring.

              We have a alot of rebound on the LF already, and the tether may be overkill not sure. I am interested to find out the full effects of it.

              Just say no...

                So last night was my first race in a new Mastersbilt and I had the LF shock drop limited 1/2" from full drop.

                Would this limiting on the LF cause the RR to wheel hop?

                In the heat my crew said my RR was wheel hopping. In the Bmain about the half way point the car came to life and started working. While doing maintenance on the car today I discovered that the LF chain had broke and I am curious if that is when the car came to life and maybe the chain was causing issues before it broke.

                  Yes, it can. That is the problem many are going to experience unless you know what your doing when you start limiting it a fair amount, however it usually doesn't show up with the small amount of limit you was doing but can happen.

                      Where can I buy the clamp to attach the tether to the lower control arm?

                          google "split shaft collar" then just search the diameter you need for your lower control arm. Just weld a tab on it for the tether.

                          it even shows some Walmart carry them, so not hard to find.

                            Kent, I am so disappointed. I was picturing a trick Billet aluminum clamp with a double shear mount for the cable. Of course, sometimes the simplest solutions are the best.

                              If it makes you feel better Kent would probably buy one, engrave a Taylormade logo in it and ship it to you for a couple hundred.

                                That is darn nice of him, but I am going to pass.
