ATV suspension mod - fabrication & fitment of spring spacers
HTML-код
- Опубликовано: 8 сен 2024
- Fitting 'lift kits' to 4x4s is something I did on a regular basis back in the UK, both to our fleet vehicles & on customers vehicles too. There are a few options when it comes to improving your vehicle's off-road performance.
The best way is to replace all the springs with basically longer & sometimes stiffer ones. This usually has to be done in conjunction with replacing all the shock absorbers for longer ones, new brake flexi lines & sometimes even transmission mounting spacers to help re-align the prop shafts with the diffs to minimise U-J angles etc...this is an expensive option though & often requires a lot of work (labour cost) so not to everyone's budget...
Another option is to fit spring 'spacers', these are fitted onto the axles usually and basically increase the length of the spring. Easy to fit and pretty cost effective in comparison to the first option.
With ATVs & RoVs (Side by Sides) the job is even easier...
Far too often I hear riders complain that the springs have 'sagged' on their ATV causing it to sit much lower than when it was new. Sure, coil springs do tend to 'settle' over time and loose their strength, but fitting winches & other equipment also compresses the suspension too reducing the ground clearance.
Replacing just the springs of the coil over shock units usually isn't an option as the components are normally supplied as a single unit. So I was thinking, why not do to an ATV what we did to the 4x4s?
I took a look, stripped a coil over shock unit and did some measurements. This video covers the machining of the spacers, the technique used to strip the suspension unit, fit the new spacers & rebuild them.
I'm often asked about this problem so I'm very confident this video will be helpful to many an ATV rider & RoV driver alike...

Awesome video Andy. Great work.
Spacers or bracket lift....tough question. Love the channel, learn something everytime I watch!
Cheers Jason :-)
My spacers changed the camber? Did you experience this too?
@@johnfazio9496 yes....youre lifting the body
@@jasonlewis995 Should I do the lift kit also or leave the camber at a bit of an angle?
@@johnfazio9496 leave it at an angle as long as its not extreme. You can preload the springs to help it out. A lift and spacers is begging for trouble.
Now thatssss a spring compressor
Incredible job and video! Thanks for sharing!
Yeah, wish I had a lathe... I need some spacers like this for my Polaris General 4 seater.
2" PVC Schedule 80 coupling works perfect, have 3000 miles on mine and no issues
But you need the shoulder to locate the spring, otherwise it shifts to one side and rubs against the shock body unfortunately
Cheers Andy
@@AndyMechanic hey Andy wondering if you still make these and sell? Looking for a set for my 2014 Yamaha Viking front and rear .... tried those pvc things and tuned mine as described. Let me know. I am in Canada
Hi,
Yes, I have sets here in the shelf for the Viking. Can get them sent over no problem. Send me an email to andymechanic@live.co.uk
Cheers Andy
What’s the difference between the 20$ spacers they sell on eBay that go on the top and the 150$ highlifter ones that look almost the same that go on the bottom
Looking at the spacers on ebay they do not have the shoulder machined into them to replicate the original collar - this provides location to the spring & keeps it central to the shock body - needed to prevent the spring rubbing on the shock body which, eventually, causes a weak point in the spring & it will break.
Hope this helps. Cheers Andy
Cool

Nice jig.
does this change the axle angle or puts more stress on the cv axle?
No, the maximum angle of the suspension A-arms is not changed. However, the A-arms & drive shafts (CV joints) will run at a greater angle for more of the time, though this angle is not any larger than it was before the spacers were fitted. The modification does not put any components under increased stress.
Have now fitted over 300 of these kits & shipped them Worldwide & had no issues reported. I'm very happy with the results
Hope this helps
Cheers

Have you ever heard of the RUclips channel "MyFordBoy"?
He does machining and castings to make things completely from raw materials.
And he never speaks.
more questions, does it make the spring stiffer, or does it only lift the car? what would be the safe thickness when done? what other metal can be used? thank you.
GR888888T IDEA AND VIDEO. I'm finding it impossible to find spacer for my Hyundai, would u suggest doing the same thing you are doing to get a lift?
Does this change the camber of the wheels? Mine did and now the ATV is cambered in noticeably in the rear.
Does it matter if you put the spacer at the top or bottom asking about a 2020 Honda pioneer 1000-3
No not really. Just whatever works :-)
Andy Mechanic thanks man enjoyed the video keep on riden
Hey Andy I have a 2015 Viking with a 2" lift kit that's a bolt on brackets on top of the shocks , basically it just pushs the shock down 2" in . Here in the US they sell the 2" spacers online, do you think the spacers will work better than the bolt on brackets. Will the spacers help with drive axle angle. Thanks for any help.
What would you suggest for a sport atv
How does this lift? The mounting points are still the same
The spacers increase pre-load on the coil spring, in the same way as when you adjust the rear shocks on a dirt bike :-)
Andy Mechanic ahhh okay makes sense
Are the spacers the same size for front and rear shocks
Same i/d and o/d but only 20 mm of lift available or spring will go coil bound on full compression of shock.
Cheers Andy
@@AndyMechanic So what dimension would i need to make the spacer, 20mm or is that the lift amount. Thanks for the reply! really appreciate it
I was looking to do the bracket style lift on my 08 rhino 660r special edition anyone see any down sides.
what utv is this for?
Spacers for a polaris 570 sp sportsman can you make?
+Dan D Sure can. Just send me the i/d and o/d of the coil spring plus how tall you want the spacers. If you send me a pic of the shock too it will be helpful. Email address is andymechanic@live.co.uk
Hey, hey, hey - I was first!
One very important question is do you know JESUS CHRIST AS YOUR PERSONAL LORD AND SAVIOR?
