A shock tower is included with every Yamaha YXZ Long Travel Kit. This reduces the amount of compound leverage to achieve a closer to 1:1 motion ration for less shock fatigue. This allows for better valving and lighter spring rates. Chromoly CNC'd suspension mounting points and a bolt on shock tower increase the strength and integrity of the stock chassis.
Customized Shock Package
for the rear, internal bypass shocks with finned remote reservoirs are included standard with every kit. This needle valve technology can be setup with light valving at ride height to deliver a smooth comfortable ride while still providing substantial dampening force at full compression preventing bottoming out during hard use. Front shocks are 12" stroke piggy backs with a soft initial hit and flutter stacks for high speed. Proper springs are provided to still allow full articulation of all 21" of travel in both high and low speed situations. These shocks also come standard with billet compression adjusters which allow for 30% adjustment range with a click of a dial. Please note rebound is tuned into the valving and cannot be changed externally as IBP clickers (regardless of manufacturer) only allow 5% external adjustment.
IBP Front Upgrade
Intended for the Aggressive Duners, Racers, and those who like to push it that much harder. This upgrade extends the same internal bypass technology included in the rear shocks to all 4 corners. This patented needle-valve design allows for less bottoming and shock fatigue on square edges, G outs, long distance racing, jumping, etc. where the front end needs a little more. While a little more harsh on initial deflection, these IBP's get pushed, the smoother the ride.
3.0 Rear IBP Upgrade
Reminder: HCR shocks are Full Offroad Shocks, not UTV shocks. An HCR Race Series King 2.5 has a larger piston and internals than a standard 3.0 UTV shock. This will also add and additional 16lbs per corner. 3.0 shocks should only be considered in BITD/ SCORE/ Long Distance Race application.
ADDED WHEEL BASE
The track width has been increased by 4 inches on either side, with a 4 inch longer wheelbase, 2 inches forward and 2 inches back, for added travel and stability. 1.25 inches additional clearance has also been added to all arms for added ground clearance.
RCV extended axle bars are included with the purchase of each kit. These 4340 Chromoly axles boast twice the strength of a stock axle and produce the highest torque test numbers of any aftermarket UTV axle. RCV also offers Tip to Tip assemblies for the HCR Long Travel kit as an upgrade.these complete half shaft replacements are designed as a hybrid between a convention UTV plunging CV axle still and RCV patented "bootless" technology. Proven to be almost 3X stronger than factory Components. Both shafts and completes are 100% manufactured and assembled in the USA.
The engineers at HCR were able to produce incredible numbers on the XXZ Kit. At 20 inches front and 21inches of rear travel and 4 inches of additional wheel base; the suspension has been completely redesigned. The extensive time in R&D allowed increased travel numbers without interfering with critical characteristics such as bump steer; adding less then 0.3º of change from factory. Caster / Camber settings have been embedded into the design of the Suspension eliminating the need for an adjustment heim, which reduces internal structure of the arm and presents a weak point upon impact. Impressively, HCR achieved a minuscule 0.06º change in caster / camber throughout the front Travel Cycle and 0.00º fluctuations throughout the rear travel cycle.

An iterative process is used during each design to simulate and refine the new geometry to match the characteristics of the stock suspension while increasing suspension travel. Critical measurements are verified, such as ball joint angle, CV joint angle, and clearance to surrounding parts to ensure no binding or interference.
The quality fit and finish, ease of installation, and top shelf performance of these kits are what sets HCR Racing apart from the competition. No kits are released to the public without numerous hours of vigorous testing in the rocks, desert, and dunes for true dual sport application.
