Bypass tuning

need help adjusting my triple bypass tubes. All my shocks were valved and tubes preset by downsouth Motorsports. Fronts are set at -LC-5 SC-5 R-6
Rear is set at LC-5 SC-5 R-10
Front bottoms out once I get into bigger stuff and rear bounces around as if it needs more weight back there. Do I close the longer compression tube to help with bottoming out?

 

Bump

It's an 08 Tacoma DCB long bed with American Motorsports front race kit with engine cage.Dmz spring under in the rear with bedsaver cage. 12" Fox triple bypass in the front with 12" King coilover. 16" fox triple bypass in the rear. Here's what's in there for valving. First tag in pic is rear bypass, and front bypass tubes are set at LC-5, SC-7, R-6. Rear bounces around as if it's to light and needs weight to help keep it down.

 

I messed with the shorter tube earlier and it made it stiffer on the street. Someone told me fox are backwards where the longer tube controls the bottoming out zone. The rear was just revalved from 3/2/70 to 2/2/70. I had them speed up the rebound and it helped but still not perfect. I tried adding a 50lb weight but it didn't make a difference. Ill add another 50lbs and see what it does. I'll get some video as well and post it to see what you think

 

Yes on the Fox bypasses, the longer compression bypass tube controls the Bottoming harder zone hits. On all bypasses the tube highest up towards the top of the shock controls the bottoming zone. Do you have anyweight in the rear at all? Fox shocks due to design always usually need more valving or they tend to be soft. For the front make sure you have the King coilover at 150psi and All fox shocks at 200psi. If you said the front is too soft which they look like they are have your front bypasses at roughly rebound nearly closed or 3/4 closed, short tube 1/2 to 3/4 closed and long tube 3/4 closed try this, and for the rear try to keep a spare back there at least, and nearly full open rebound tube, short tube 1/2 way closed and long tube for bottoming start at 1/2 closed . Put zip ties on the shafts go test the shocks, see where they are ending up at. If your hitting big stuff and zip tie is ending up towards the bottom of the shaft, then slowly start turning in "closing" the long tube. And if the slow to mid speed driving will be your short tubes.

 

@Anthony250 Perfect thanks! I'll try that and see what it does. I like the zip tie trick great idea lol
