CUSTOM SHOCK VALVING & SHOCK SERVICE

Pioneer Performance can valve any of the re-buildable shocks to better suit your riding style. We have many years of experience with many different brands of shocks. This experience allows us to come up with many different shim stack designs. Below is a brief description of some of the more common shock re-valve services that provide a significant improvement in ride quality over the standard stock set-up. Price to valve most shocks is $47.95 (unless noted, which includes re-build) each or $179.95 for a set of 4 (36mm non reservoir). Shocks must be sent to Pioneer Performance to have changes performed. Remove all hardware (bolts spacers etc.) when sending shocks in for service, Pioneer Performance will not be responsible for these items.

On the following models all shocks can be serviced:

'08 NYTRO FX & RTX

The Nytro's are on the firm side in both the smaller and stutter bumps. We use a combination of both progressive, and staged valving. This combination maintains the sleds bump ability while giving a much better (plusher) ride in the small and stutter bumps. The floats on the front of the RTX can also be vavled to produce a much better ride. Cost to do the 2 rear FX shocks is $107.90, cost to do all 4 RTX shocks is $239.80. 

'09-'10 NYTRO XTX

The Nytro XTX is on the firm side everywhere. We take the rear shocks and soften both the low and high speed dampening, with a staged progressive valving combination to achieve a nicer more compliant ride. Cost to do the 2 rear shocks is $107.90.  

APEX GT

Many people purchased the Apex GT because of the excellent shock combination. The sled was set up to be a plush trail cruiser. To make the sled more able to handle the bumps a valve change in the electronic Ohlins mono shock is a must. We have an excellent combination of compression and rebound dampening, based off of the European settings, with a few changes. We have tested several combinations and can tailor the shock to fit your riding style. When we're finished you'll have a sled that when making the electronic adjustment, has much more range, soft to stiff. Also the rebound dampening is adjusted, a must when increasing spring pre-load or going to a heavier rear spring, also creating a wider range of adjustment. An optional heavier spring is recommended for aggressive riders or 190 lbs. + (see spring page for optional springs) along with the re-valve. Cost to re-valve the Ohlins electronic is $89.95. For those looking for peace of mind we can install the new x-ring seal head (Ohlins upgrade) while we have the shock apart for valve changes, cost for the new seal head is $59.95.

'06-'07 NYTRO & '07-'09 APEX RTX

The Nytro and RTX are designed as a bump sleds, unfortunately they seem to only handle small bumps well. We have an excellent package for the rear of these sleds which includes changing the internal pistons (valve pistons), valve shim stacks, and center shock spring. This combination turns the Nytro & '07 RTX into excellent bump sleds. The small bump ride is more compliant, while soaking  up the larger bumps much better with less bottoming, along with greatly reduced "kick back". Our test Nytro with this suspension setting along with a heavy stabilizer bar and performance clutch kit is a blast to ride. This combination of shock re-valve, piston, and center shock spring retails for $219.95.

MONOSHOCK RESERVOIR KIT

Looking for the ultimate in suspension performance from you Monoshock suspension. We add a compression adjustable reservoir to you KYB RA shock, and custom valve it. This modification allows you to adjust the compression dampening separate of the standard rebound adjustment (the RA allows you to change a high percentage of rebound dampening, while changing compression slightly). By being able to adjust the compression separately it gives you a much larger range of adjustment. You'll now be able to set compression to handle the bumps, while adjusting the rebound for the desired ride and amount off "feedback" from the suspension. The reservoir also increases volume and cooling efficiency for more consistent performance from the shock. Shock must be sent in for installation. Monoshock reservoir and installation is $349.95.

APEX (ER & '06 RTX), ATTAK (LTX)

Like the mono shock RX-1 the Apex and Attak work well in the smaller and stutter bumps. When you start pushing the sled in the larger or "g-out" bumps the suspension will blow through the travel. We change both compression and rebound dampening to reduce this affect, improving the ability to be ridden aggressively with less frequent bottoming. For the more aggressive or heavier riders a spring change is recommended along with the valve change. Cost to re-valve the 46 millimeter KYB rear is $69.95.

SX VIPER

The 2002 (standard and ER) and 2003 (standard) Viper suffers in the rear from a poor ride due to being over dampened, much of the problem is too much rebound dampening. After hitting a bump, or a series of bumps the suspension “packs up” and can’t do its job, creating a very stiff ride. By changing the dampening we can offer both a greatly improved (plusher) ride with the ability to handle the bumps well when riding the machine aggressively. The 2002 models also suffer from very stiff compression settings in the ski shocks making the front ride harsh, and will also benefit greatly from dampening changes. Set of 4 shock re-valve is $179.95.

RX-1 MONO SHOCK

The Mono Shock RA suspension works well in most situations, one of the weakness we’ve found is for the more aggressive riders. When riding aggressively bottoming will occur especially in “G out” bumps. We adjust the compression and rebound dampening, by doing this it improves the ability to ride aggressively, and by not having to adjust the RA to full stiff, the suspension will still rebound, maintaining a good ride quality. Retail price to re-valve the 46 millimeter KYB rear is $69.95.

VMAX XTC

When the XTC was introduced in ’97 many people felt they could ride them aggressively due to the long travel suspension when in reality it was designed as a plush cruiser. We can valve your rear shocks and change the center shock spring. This combination is a major improvement and we can set them up for both more aggressive or heavier riders. Combination of shock valving and center spring is $153.85

SX-R

The SX-R suffers from much of the same ride quality as the Viper, over rebound dampening causes a poor (stiff) ride. By reducing the rebound dampening and adjusting the compression, the ride can be greatly improved, giving you the true benefit of the lighter weight (compared to the Viper) of this sled. When finished the suspension has a much better “stroke feel” while also allowing it to soak up the bumps when ridden aggressively. Set of 4 shock re-valve is $179.95.

PHAZER FX

We love the new Phazer, only problem it lacks a little when pushed. We change the valving to reduce the bottoming and the feedback ("kick"). Internal pistons are changed, along with the shim stacks. Cost to valve the 2 rear shocks is $149.95.

SHOCK SERVICE

Pioneer Performance is a service center for Yamaha Kayaba and Soqi shocks. Whether you’re looking to change the ride of your sled, freshen your shocks up after a hard season of riding, or you have some much needed repairs, we can handle all of your shock service needs, we can change a complete shaft assembly if necessary ! We can also handle your Yamaha Ohlins, and Fox Float shock service and repair needs. Standard re-build includes changing the oil, floating piston O-ring (o-ring n/c on 36mm KYB's only), and re-pressurizing. Re-valve includes re-build service plus valve change and shims ($47.95 covers both the re-valve and re-build).
