Good to know Rob , I had thought about this for years and if you say they stretch badly , I would have to say this isnt going to work then .

Never tried it , but always wondered if it would .

Thanks Johnny

i would argue the best limiting straps available then are ratchet straps, lol...i think thats what Brayden used on Jerrod's truck when he took it to 11.55.

Jordan don't want to call BS my friend, but you would have to show me a truck that can cut a 1.6 on a stock rear end suspension and no clamps tire pressure, weight or not. I've been around a lot of Dmaxes and owned a few myself. I never seen a stock truck suspension cut anything close to a 1.6. I have run toyo's down to 25 psi in the rear, used clamps, or cal tracks and had a pretty fast truck. (12.0 111+) and never once cut a 1.6 sixty with a good launch. That is with a twined truck with dual cp's and injectors. That is one hell of a truck my friend would like to talk to him or them, I'm missing something.

We got a 1.9 60' out of a heavy 2WD with a bone stock suspension - no clamps or anything. 2nd gear launch and my 28x11.50 cheaters on the rear. I'm pretty sure if we took the clamps off of Chris's or the traction bars off of mine we would both still be in the high 1.6 60's.

Im not nitpicking here, but when we talk about low 60ft times, we MUST include what tires we're running. Unfortunately, you just cannot compare launches using street tires (Toyos) with launches using drag radials or slicks. They just arent in the same area code.

.03 between the 2 on Wendy. For that I will stick to my Toyo's. Less work for my pit crew Chris or Pat :rofl:

also i feel its a good idea to state what other guys are running at that track . not all tracks have equal grip . if everyone else is hitting 1.7's and you know they are competint racers and you tag a 1.6 ... that 1.6 becomes much more special than it would be if it was the norm .

there are mroe then one model bilstein so the vavling maybe different fron model to model in the same length shock. i talked to nick and norcal about the option for a while. slow rebound shocks are waht you want in most application on many vehicles. when having the bars cranked up it makes it even worse because off the added preload on the suspension. if you have lowered your front suspension your going to want slightly less rebound resistance and more compression resistance to prevent bottoming all the time. shocks are so much fun, haha. much more complex when most people know. most pickup shock use more of a check valve system compaired to valve stacks. vavle stacks give you much more control though.

All the cars there complain about track prep and poor 60' times. We are typically the only Duramax's there and always cut better 60s than the Dodge guys and other Duramax's.

Mine and Chris's trucks have cut 1.6 60's on
nearly bald 285-70-16 BFG ATs
255-85-16 Tempra Trail Cutters (M+S rated tires)
28x11.5 MT ET Streets

Mine has also done it on 305-50-R20 Cooper XSTs

Chris's has also done it on Toyo Proxes

My best 60 that I can recall is a 1.59 on the MT ETs - but I cut alot of 1.66 on all 3 of the others, so to me there isn't a significant difference there. Now that I'll have the power to need the added traction of the ETs we'll see how my 60' times do this year.

that is a good point but the shocks i installed are what is normally bought for our trucks , they were sold to me from norcal truck . not his fault they were not built for racing there is only one model stiffer from bilstien . so far on my QA1's 5 clicks compression and 12 clicks rebound is quite nice... stiff, controlled , but by no means harsh . for drag racing our trucks you need a ton of rebound ... i still have 12 more clicks so stiffer on rebound , and 19 more clicks compression , the QA1's are looking to be the best option for our trucks if you got the $$ .

you keep stating this and by no meens am i dismissing it there good #'s but take a poll and those are not average results also those are on 2nd gear launches wich i already lunched one converter after 4-5 tests on the street , not all trucks like the secound launch . though i agree in my few test it looked promising .

ya rebound is very important, dont what the front end bouncing down the drap strip. im going to get bilstein from nick but getting the slowest rebound model they have. another option is dual shocks but with a lowered truck that is a little hard. clicker shock your going to pay for. do those have reservoir? most compression adjust shock have reservoirs becasue it alot easier to have an adjuster that way. rebound is controlled with a ophice holei n hte shaft and it being all the way open to all the way plugged. they use hollowed shafts when run a needle rod down the center with an adjust on the eyelet changing the postion of the needle in front of the ophice hole. they are many kinda of compression adjusters

no res. , and they are double clicker , and you are quite right fully clicked seems to be almost closed on the fluid port . the 4000/1000 bilstien might wok better . the bilstiens are ok for the average truck rode smooth but to squishy for serious use . wether racing or getting sporty the truck had a sloshy feeling to it , not any more :cool:

i see i see, i like reservoirs better but your goign to pay for it on the pickup just like snowmobles or quads. i keep telling myselfi should just build a set of shock for my pickup but id be taking them in and out about 10 times to get the vavling right and a set of pickup shock, 400 bucks or less, shocks id put in 400+ a piece, haha.
