We now carry 400mm Adjustable Shocks that work great with this kit, they can be found in the related products section below!
This kit includes only the upper shock conversion components. If you currently have our Yamaha Blaster Widening Kit and you want to upgrade to be able to use longer shocks with that kit, then this is the kit you need to allow for those longer shocks (shocks not included).
Although we recommend one of our full widening and shock conversion kits or widening and lowering kits, we also want to give customers the pieces to experiment with different “Quad-rodding” solutions to get the modification they are after.
Possible uses of this kit include:
1. Lower the ATV without widening it, by moving up the top shock mounting position. (also gives ability to quickly change the amount that is lowered)
2. Mount longer shocks on the ATV without any other modifications (again, we recommend doing this with our widening and shock conversion kit to allow enough room for proper shock angle)
3. Ability to adjust the “tilt” of the ATV by adjusting one shock position differently from the other for circle track racing.
4. Combine with longer a-arms to use stock shocks with custom a-arms if the a-arms usually require longer shocks.
5. If you previously purchased our widening & lowering kit, and now would like to have the shock components to widen the shocks to match the a-arm spacing.
6. If you previously purchased our widening kit for stock shocks and now you want to be able to upgrade and use longer shocks.
There are products available on the internet that allow you to lower the rear of the ATV. Diamond J Customs doesn’t currently offer a rear lowering kit.
Another way to purchase this kit, is to look at our eBay store to see if we are running any “Highest Bid” auctions on Shock Conversion Kits. Even if the auction kit is for a 300ex to 400ex shock conversion kit, you can purchase it and choose this kit.
Diamond J Customs’ a-arm and shock widening kits are a unique approach to increasing the width of an ATV. Instead of replacing the a-arms with custom built, expensive after-market a-arms, this kit simply relocates where the a-arms and shocks mount to the frame. The precision laser-cut brackets supplied in the kit bolt to the stock mounts on the frame, and provide two sets of new mount locations for the a-arms and shocks that are 2 ¼ or 3 inches outward on each side. This provides a 4 ½ or 6 inch total (including both sides) increase in the width of the ATV while making use of all of the stock suspension components. Threaded tie rod extensions that thread onto your stock tie rods and secure in place with jam nuts are also supplied to extend the steering tie rods to match the widening kit.
Some of the widening kits for ATV’s 300cc’s and smaller have the option to include shock mount kits that are adjustable to allow the customer to vary the ride height of the ATV, utilize longer shocks, or both.
Kits come complete with all necessary hardware to make the conversion to a wider stance. Please specify if you want the tie rod extensions for the +4.5″ or +6.0″ setting by letting us know at the time of ordering. If we don’t hear from you within a couple days, we will assume you want the +6 kit.
Shocks and a-arms are not included with any of the kits. The words “shocks” and “a-arms” appear in the title because these are the parts of the ATV that are widened, not because they are included. After-market a-arms and shocks will work with this widening kit, but they are not required.
The kits require no cutting or welding and can be installed easily in an afternoon by a typical home mechanic / do-it-yourselfer. We have installed many kits, and it takes us less than an hour to install a kit. Brake lines are typically long enough for the conversion if the intermediate brake line support on the a-arm is disconnected to provide more slack in the lines. Rerouting the brake lines around frame members to give a more direct path to the hubs can also help. Longer brake lines are available in our eBay store if you prefer to also make that modification. The following ATV’s will most likely need longer brake lines for the +6″ setting: YFZ450, 450R, Raptor 250 and Z400.
Some of the pictures show the ATV’s with the front bumper removed so you can see the kit more easily. The bumper mounts are not affected by the kits. Stock and aftermarket bumpers should work fine with all kits.
Steel brackets are made from 1/4″ thick carbon steel and are designed to be used in all types of riding and racing, including motocross and GNCC. Many customers are using these kits to race every weekend. The a-arm mounting brackets are designed to be as strong as the a-arms connecting to them. The eight separate brackets work together to share the load in all directions (such as rough terrain or hooking an occasional tree on the trails). These kits ARE designed (and used) for the harsh conditions of motocross racing. Maybe 1/4″ steel doesn’t sound thick to you, but anything thicker would be overkill (keep in mind the frame brackets that these mount to, are 1/8″ thick steel. We have never had an incident where our kits have caused cracking of the frame mounts or frame joints. Because the widening brackets mount to both sides of the frame, and span both mounting locations, the loads are more easily shared between a larger area, which helps make this a very rigid and robust setup.
All kits come powder coated gloss black. Color choice is not available, but other colors can be painted or powder coated by the customer over the gloss black finish. Kit components go through a seven stage chemical dip cleaning process, are electro-statically dipped in black primer, baked, then powder coated and baked again to a super high-strength gloss-black finish.
