How to Rebuild a King Bypass Shock or Coilover Shock
Вставка

- This how to video will show you how to rebuild a bypass shock or coilover shock used on prerunners. We use a King 2.5 2 Tube Bypass Shock. If you have a prerunner that uses coilover shocks or bypass shocks, this video will show you how to rebuild them.

Man, that looks super simple. I'm definitely not afraid to tackle taking a shock apart now, nor will I ever pay someone to work on my shocks again. I paid King like $150 to replace a shaft and seals once. Never again!
Very nice bro....I used to do my own mx shocks and fairly confident I could redo one of these....plus king is right down the street if I need parts
bad ass vid. we need more like this! Next one should be on tuning compression/rebound tubes
@ovrebo1 That is actually not a bad price when you consider the shaft replacement. Glad this video helped you!!!
Great video, now off to rebuild mine
Excellent video
this is fricking awesome for thus of us who live in baja and can't just run out to a local dealer and get our shocks serviced ! thanks
Glad it helped, have you watched our FullDroopTV series yet?
@SoCalRiderXspadesX Glad you liked it....look for more coming real soon.
Thanks for posting up this video, Ive got a set of HKS coilovers for my R32 skyline, one shock's been stripped by the previous owner who i bought them off but looking at the internals of that and the internals of the one you rebuild, they dont look too different so i'm gonna try rebuilding my coilovers thanks to your vid. Just one question though, how much pressure do you fill your shocks too, ive been told HKS needs 85psi nitrogen seems abit too much to me though.
Im also confused about the floating piston height in the nitrogen resovior, if all my fluid has leaked out Im assuming the floating piston location is incorrect. Is this something I should be concerned about or am I missing something? Thanks for the video, a rebuild is less intimidating now Ive seen you do it.
really easy, thanks.
@down4glamis Alot of people have made mention about the IFP we simply ran out of time. We did include bleeding out the air when the person in the video turned it upside down...
How often do you rebuild this shocks
This is a draw back for me for getting in to kings
@DJTONER1 I don't think you want it to fully compress. Shocks don't make good bumpstops. I haven't opened up a Race Runner shock before.
Amazing video thank you !! Think you could give me a hand with how much nitrogen I would need and oil type for my shocks
King shock oil is what I use in my King and ADS shocks on my truck, I use the same with my FOX shocks on my SXS. A gallon of oil was $40 off Amazon. 2.5" shocks @ 180-200 psi seems to work well for me.
@TheMadRaver That's a hard one to answer without seeing it. It sounds like it needs a rebuild.
Is there a level of oil refill or how much do I have to fill
Question.
I just bought an icon setup from a buddy that went long travel.
I accidentally twisted the res on the piggyback while cleaning the shock and needless to say, I lost pressure and a little bit of oil.
Can I just recharge the shock with nitrogen or should I send it in and rebuild it?
Thanks
@BajaGuy21 We will keep that in mind. Might have to wait to get the shock on a truck. The next one is going to be how to shorten a bumpstop.
Should the shaft on my racerunner 2.5 8" coilovers go all the way in the body? Mine seems to stop about 3/16" to 1/4" inch from full compression.
if im changing oil in 2.5 with remote resi, do i just fill the body? or do i have to to open the resi?
GREAT VIDEO BREW!! are u located in AZ? need help revalving/rebound set-up on King shocks for rail.
+KOCK'S TV HE is located in Las vegas NV at Aftermarket hq 702-202-1263
@The64twins About 150-200 psi is the general rule of thumb
When do I know it's time to rebuild my shocks? They seem do be doing great. I'm very happy with my Kings!
Great video. Really appreciated from Cambodia which we really need help with 4x4 here. So how much you nitrogen you filling up?
150 psi
my racerunner 2.0 remote reservoirs need rebuilt bad, are they generally the same design? and how do you soften them up? the rear rides like a brick shit house like theyre valved for a full size
How do I determine what valve pack I should use? I have a Silverado crew cab and don't know what pack to run on the rear, running mazzulla hangers and shackles, king 2.5 triple bypass but don't know what valving
Call King, they'll send you a valve stack.
I bought Triple Bypasses from a local shop and put them on my truck myself without revalving them accotding to my truck. they are super stiff and need to go from where it is now which is a 20/10 stack down to a 12/10 stack. what shims do I remove and how many (rebound...compression..Larger ..smaller)? Also I dont have availability to fill up nitrogen myself.....could I put them on and then drive over to a shop and have them refill the reservior without hurting the shock? I look forward to your response @prerunnermaniac
I would take them apart and see what you have. Make sure they don't having any added shims to the stack. a Normal stack is 7 shims. When you go up or down you change the whole stack. ( but you can tune them how ever you see fit ) The shim stack towards the shock shaft is the compression side and the other is the rebound. It won't hurt the shock with no nitrogen, In would drive it straight over and fill it up. I would jack up the truck and take the weight off of the shock while filling it up.
@prerunnermaniac I know that i was just compressing it after i put on some 90 degree fittings on them
@onhardland Glad you like it. We are planning to do more of these so be sure to subscribe.
@down4glamis You didn't need to remove your comment. We appreciate feedback. This helps us make better videos. Now that UA-cam allows 15 minute videos we will expand on subjects in the future.
Where did you set the floating piston
ever figure that out?
It should be but since we haven't opened up a Race Runner I can't be for sure.
@prerunnermaniac Yea thats best way to clear the tubes of any air, but there is a small air pocket that occurs willing putting the piston/seal cap in. setting the IFP helps the final process. sorry to critique, if you guys need a hand just send me an email.
why didnt u rebuild the ifp?
Yes the coil springs are what extend the shock back. In this case you would need some sort of spring in conjunction with the bypass shock. If you want to see us install some bypass shocks check out our video on how to install a bedcage.
I don't know about HKS shocks exactly but 85 psi is about right. I think we put about 90 in our shock.
prerunnermaniac I know this is a old video but that’s seems kinda low on the nitrogen level. Generally we run 200 in our shocks. I haven’t seen someone run anything under 150 in a shock
Yeah, if you noticed he isn’t even filling with nitrogen. He’s using compressed air!!! 0.0 big nono moisture corrodes aluminum eventually and there’s not enough pressure
@Ebktilltheday, nitrogen tanks have air hoses that he used. It's what I fill my tires with.
How much Nitrogen do you re-fill with? Until the shaft is all the way out?
Believe it's 150psi ...nevermind, 9 yrs later, lol
@@kirkdunn1379 🤣🤣🤣 SpongeBob voice right there. 9..yeasss.... lataaaa.....
That video stretch though
That is a big shock.
I GOT SOME OF THESE BAD BOYS ON MY CAR.
IT IS A LOSI BAJA REY 1/10 KING SHOCKS BAJA REY CAN,T AFFORD A REAL ONE AHH WELL
😁
