Carnes84 Posted September 10, 2022 Report Share Posted September 10, 2022 Ok. I have a 1981 720 4x4. Trying to figure out why I have 2 shocks per side on the front end . I've done a decent amount of googling and can't find any good information on why mine is set up this way. They are in Dyer need of being changed. Any info would be helpful. Thanks in advance. 1 Quote Link to comment
]2eDeYe Posted September 10, 2022 Report Share Posted September 10, 2022 Welcome to ratsun. That is a product of the 1980's lol. Do you know if the original shock tower was removed? 1 Quote Link to comment
datzenmike Posted September 10, 2022 Report Share Posted September 10, 2022 It certainly wasn't stock. The shocks on it now will have part numbers you can ID them from. Up to you is replace them or go back to a premium quality stock shock. 1 Quote Link to comment
NC85ST Posted September 10, 2022 Report Share Posted September 10, 2022 It would be interesting to see pictures of this. Shots of the upper and lower mounts. 1 Quote Link to comment
bottomwatcher Posted September 10, 2022 Report Share Posted September 10, 2022 There is barely clearance between the front halfshaft and one shock. I think I remember a kit with a hoop that went over the top of the upper A arm. Pics would be cool as I have an 82. I always went for the Rancho 5000s and liked them. I changed them out around 100k but they still felt good. 2 Quote Link to comment

Carnes84 Posted September 10, 2022 Author Report Share Posted September 10, 2022 I'm thinking the original shock location is still there. I'll take a few pictures when I get home in a couple hours. 1 Quote Link to comment
Carnes84 Posted September 10, 2022 Author Report Share Posted September 10, 2022 If I can figure out how to load them on here 1 Quote Link to comment
Stoffregen Motorsports Posted September 10, 2022 Report Share Posted September 10, 2022 What color are the shocks? If white, most likely Rancho. You can buy shocks based on their dimensions and Rancho has a link somewhere on their website with mounting style (pin vs eye), shock length extended an shock length compressed. If you remove a shock, you can get these measurements pretty quickly. I think the website has it listed under the "application guide", or something like that. 1 Quote Link to comment
Stoffregen Motorsports Posted September 10, 2022 Report Share Posted September 10, 2022 Well, Rancho has changed their website, but I did find these useful pages - This one is for generic shocks, but there are waaaaayyyyy more lengths and styles available than are listed here. https://www.gorancho.com/downloads/product-catalog/2017_rancho_customshocks_accessories_secure.pdf This is their comprehensive shock listing by style and length (extended and compressed) but you'll have to pour through the pages to find what you need. https://www.gorancho.com/downloads/product-catalog/2017_rancho_shockspecifications_secure.pdf Or you could just pick up the phone and call 4 Wheel Parts and give them the dimensions and have them do the legwork. https://www.4wheelparts.com/ Like I said, call them. Don't look through the 4 wheel parts website. You'll never find them. 1 Quote Link to comment

Thomas Perkins Posted September 10, 2022 Report Share Posted September 10, 2022 (edited) This is what OR'eilly's is showing for the front.Don't see any for the back.I got mine back in 2005 from OReilly's.It also says with a front raised 1 1/2 inches.So maybe someone raised your front end and added a taller shock.I found another site that has these Rancho front shocks and it also says the front has to be raised a 1 1/2 inches.The new style is Rancho 5000x.. Your's might be for a 79-81 model.Napa has these too.I had to put in Datsun.I can't find the rear one's.https://www.oreillyauto.com/detail/c/rs5000x-series/rancho-rs5000x-series-shock-absorber/ranc/rs55605/v/a/8237/automotive-truck-1981-nissan-720-pickup?q=shocks&pos=9 Edited September 10, 2022 by Thomas Perkins 1 Quote Link to comment

Carnes84 Posted September 11, 2022 Author Report Share Posted September 11, 2022 The shocks are yellow. May be spray paint though. I can see a sticker but it's the same color as the shocks. 1 Quote Link to comment

bottomwatcher Posted September 11, 2022 Report Share Posted September 11, 2022 Might need replacing? The inner tube is now out on the rear one. Delete the rear ones and replace the inner with I guess whatever you want but definitely do not drive this on public roads until this is fixed. Upper ball joint torn boot and escaped grease with no zerk to service it. This front end is going to need some love. 1 Quote Link to comment
]2eDeYe Posted September 11, 2022 Report Share Posted September 11, 2022 The one through the a arm is the stock location, the other one was added. You should be able use the links Stoffregen Motorsports posted to find a replacement for them them. 2 Quote Link to comment
Carnes84 Posted September 11, 2022 Author Report Share Posted September 11, 2022 Any idea why the second one was added? 2 Quote Link to comment
Stoffregen Motorsports Posted September 11, 2022 Report Share Posted September 11, 2022 Because more is better. Someone mentioned that back in the '80s and early '90s, dual shocks was a thing. Most trucks didn't need dual front shock, like ever, but some people thought they would help. This idea may have come around the time when most OEM shocks were hydraulic and the gas shock technology was emerging. I personally like hydraulic shocks on a truck because they reduce the possibility of "scuttle shake" inherent with the body on frame split body (truck cab and bed) design. The RS5000 series Rancho shocks are hydraulic. 1 Quote Link to comment
Carnes84 Posted September 11, 2022 Author Report Share Posted September 11, 2022 Makes sense. Also explains why I can't find anything similar in Google search. I've been scratching my head for almost a year over it. 1 Quote Link to comment
datzenmike Posted September 11, 2022 Report Share Posted September 11, 2022 They are all oil filled and hydraulic aren't they? Pressurized with Nitrogen gas to reduce foaming. That's why they extend when relased. 1 Quote Link to comment
