Has anyone ever rebuilt the rear shock on a '99 Scrambler? I had to crank my spring up 3/4 to level my ride out. Is this because of my shock or my spring? I have the stock red spring on it. Is there a stronger spring for a 220lb rider or rebuild/purchase new shock?

Thanks
Scott

 

The current ATV Sport has a nice article on rebuilding shocks. From the pics it looks like they used a '99 Sport rear (non-reservoir FOX), although they never specifically mention it.

 

Great call on the article, also, a sled place called Carver Perf. Thief River Falls MN. 1-888-349-7469...www.carverperformance.com offers a do it yourself video. Most places will charge around $30 per corner if you don't feel comfortable.

Good Luck,

500SCR,

Before you go out and get the shock rebuilt, think of this. The reason the rear shock is sagging in the back is because it was built that way. This is called "sag". It's good to have some sag in a machine (especially Polaris machines) because sack allows you to lower the ride height to make it less top heavy and allows it to steer easier. Don't worry about losing the top couple of inches of travel, it'll still be there if you go off of a jump. The correct way of setting sag is to sit on the machine and measure how much travel your machine loses. The correct amount is about 1/3rd to 1/2 of the travel. This means that when you sit on the machine you should have 2/3 to 1/2 of the travel left.

Some suspension systems (ZPS or Zero Preload Systems) have almost the entire length of the suspension travel as sag. Instead of using the springs to cushon the landings of jumps, it uses the compression dampening of the shock itself to cushon the hit. Most riders very seldom hit big obstacles that cause the suspension to compress much past the first few inches anyway.

 

I had my 00 scrambler rear rebuilt and revalved at carver performance. He did a real nice job, and set it up to my weight and riding style. His prices are very reasonable also. I have mine set with about 4 inches of sag with me on it. This helps out incredibly when going fast in the rough stuff. It allows the tires to drop down into the bump and come back up without hardley feeling it.

 

I had the rear rebuilt by my dealer for $50. This was just a standard clean, recharge the gas and replace the seals. It made a huge difference in my suspension performance. I set the rider sag at about 1/3 the total travel also. Polaris does have a heavier duty spring for heavy riders. I posted the part number in a similar post about 8 months ago. HTH

 

Mike,

Is the official term "sag" or "sack"? Many people refer to grease fittings as "zerts"........when they are really "zerks" and so on and so on. I've read suspension sag referred to as sack before, and thought it was a just a misunderstanding. Anyway, hearing you refer to it as "sack" just makes me wonder if that is the correct terminology. Just trying to learn.

Thanks,

Waylan

 

Walexa,

Sometimes people (myself included) get the terms mixed up. Sag is the amount the rear or front drops with the rider on board. Sack is generally refered to as the springs or other suspension components being worn out (i.e. He bottomed out hard because of a "sacked" out suspension). The terms are used often used interchangably.

Very interesting........Walexa, we're all learning, good call, isn't the net grand!!!
