Bypass Shocks With Compression Adjustment

Bypass shock absorbers are designed for ultra-performance for Jeep Wrangler JK, racing cars, ATV, and UTV. With compression and rebound adjustments optional and outer bypass, it can provide extreme damping force and rebound force whenever you need. EPIK bypass shocks are made of a 2.6” steel tube and 22mm shaft which make it stronger and more durable. Equip our shocks and enjoy your extreme racing.

Product Features

With ultra precisely grinded 35CrMo alloy steel piston rod, thickened straight quilting milling steel tube and T7075 aviation aluminum machined parts, the shock intensity and piston motion smoothness have been enhanced greatly. Overall tensile strength is over 1000KN. Safety is guaranteed as there will be no malfunction such as break, bending, and wearing oil leakage during racing or high intensive off-roading.

Shocks have been calibrated strictly before mass production. Through driving on different road sections like express way, bumping roads, mountain roads, rain forests, and racing terrains, damping force is adjusted according to different drivers’ feelings. In this way, shocks can be adjusted to meet the maneuvering demand of different drivers.

Off-road driving comfort is strictly connected with the vehicle’s suspension system. Only shocks with good damping performance can provide effective long-journey driving without damage to the CV joint and wheels. Comfort is not only related to the product’s factory setting damping force, but also affected by the thermal attenuation, wearing attenuation, and valve system responding speed on emergency road sections after a period of driving. EPIK shock absorbers use a mono-tube design which has fast valve responding, Germany FUCHS5045 racing oil with a working temperature of -45~160℃, compensation design of parts wearing to ensure slow damping attenuation and double-insurance inflating seal design to avoid air leakage.

Low Noise
EPIK shock absorbers use Germany FUCHS racing oil to reduce the friction noise between oil seal and piston rod and Teflon piston ring to reduce the friction noise between the piston ring and tube inner body. Shocks are properly assembled and each shock will be tested to ensure its low friction force before it leaves the factory.

Adjustment Design

EPIK shock absorbers have three types of adjustment: Compression adjustment, Compression + Rebound adjustment, Compression + Rebound + Internal bypass to meet the demand of entertainment off-road, long-distance travel, and high-intensity competitions. Internal bypass is suitable for racing and long-distance travel. Damping force during medium travel of the shocks is soft to ensure the comfort of daily driving and slightly bumping roads. The damping force of end travel 3.5cm is enhanced to ensure flying jump and extreme bumping roads to ensure that the shocks will not hit the bottom and protect the suspension, CV joint, and wheels of the vehicle.
