Any one ever heard of these shocks for ATVs? http://www.dmshocks.com/default.asp

They sounds pretty decent...

Specs:

2 WAY ADJUSTABLE SHOCK ABSORBERS

DMS 2 way adjustable shock absorber is designed with a large diameter high flow piston that allows excellent control and easy tuning. This shock absorber is designed with a unique adjustment system that allows the rebound to be adjusted without effecting the compression (bump) setting and likewise the compression can be adjusted without effecting the rebound.This system allows the operator to arrive at the optimum setup in a very short time. The adjustments are made through the one shaft (no remote canister). There are 3 shafts within the 1 shaft, (outer shaft,rebound adjusting shaft and the bump adjuster shaft). When one adjuster is turned it does not effect the others. This 2 way shock absorber is manufactured from the highest grade materials as used by the military and aircraft industry. The shafts and shock absorber body are 4130 Chrome Moly. Seals are of the highest quality and designed to minimise stiction on the shaft. The specially designed progressive rate spring gives excellent balance, traction and superior ride quality over the big jumps and rough ground. This system is best suited for entry level Flat track or recreational purposes. The performance and durability of the 2 way adjustable shock absorber is outstanding for the price and gives excellent value.

3 WAY ADJUSTABLE SHOCK ABSORBER

DMS 3 way adjustable shock absorber is designed with the DMS large diameter high flow piston which allows excellent control and tuning ability. The 3 way adjustable shock absorber comes with High shaft speed adjustment and Low shaft speed adjustment on compression (bump) as well as Rebound adjustment. The high and low speed adjustment is located on the canister and the rebound adjustment is located on the shaft. The extra bump adjustment on high speed ensures even more tunability, this combined with the unique DMS adjustment system makes the 3 way adjustable shock absorber the perfect choice for the professional rider or for anyone starting out in Motor X or Flat track racing. The material used in the manufacture of the 3 way adjustable shock is of the highest quality available. The shaft and main shock body are 4130 Chrome Moly, the canister and aluminium parts are 7075 aircraft quality alloy. All aluminium parts are hard anodised to give durability in the harsh conditions of motor sport.

4 WAY ADJUSTABLE SHOCK ABSORBER

DMS 4 way adjustable shock absorber is also designed with the same large diameter high flow piston which allows excellent control and tunability. To enhance the ease of tuning the shock absorbers to the conditions etc. DMS has added a 4th adjustment on the compression (bump) to help the professional teams/riders to arrive at the optimum setup for the conditions. With race shock absorbers it is always a contentious topic of when high shaft speed adjustment starts, or when low shaft speed stops! With the new DMS 4 way adjustable shock absorber we have an external adjustment so that at the point where the high speed adjustment starts, this point can be shifted. To tune this system data logging is required to get optimum performance from the extra adjustment. This system is best suited to Motor X or Enduro (long distance) type events. The advantages in Motor X is if a particular bump or hole is causing the quad to bottom out at a particular shaft speed, the starting point of the high speed can be adjusted down, to assist the shock at that shaft speed, and the low to middle speed shaft adjustment does not have to be altered , therfore maintaining maximum traction and ride quality. The rebound adjustment is as in the 3 way adjustable shock absorber and is loctaed on the shaft and the bump adjustments are on the canister. This system gives maximum traction and also stability through the range of shaft speeds used at any particular track. It also enables the team to get the best setup in a very short time.

5 WAY ADJUSTABLE SHOCK ABSORBER

DMS 5 way adjustable shock absorber also has all the benefits of the 4 way adjustable shock absorber with the additional adjustment on the gas pressure, this is for the teams that have data logging on their quads. This adjustment is a very fine tuning device and can also help traction etc.

All DMS shock absorbers come with specially designed progressive rate springs, which enhance the qualities of the DMS range of Quad shock absorbers. The progressive rate springs give excellent feel over rough conditions and maximise stability. This also helps with rider comfort and fatigue during racing or recreational riding.

They have many different shock absorbers, most of the distributors of Drummond are Rally Car shops, so I am guessing the shocks do well at handling high speed, bumpy terrain so I am guessing they would do well on an ATV!

Any one want to chip in so I can do a thorough evaluation?:devil:

Onlything that seems a bit wary is the shafts look a little small. BUT.. photos can be deceiving. The bodies may be larger making the shaft look smaller.

That is similar to my problem, My fatazz makes my shaft look smaller

I would chip in dave but 10 bucks wouldn't do much good.
