the latest in shock absorber "KAYABA RS ULTRA"

KAYABA RS ULTRA PERFORMANCE ABSORBER

Drive the DIFFERENCE.

HEAVY DUTY & HIGH PERFORMANCE SHOCK ABSORBER


The RS Ultra is the latest in shock absorber technology, designed to suit the very tough of road conditions. 

Its ride and handling is superb and you are assured of a comfortable ride even in the toughest of terrains. 

When it is in braking mode it reduces nose diving eliminating pitch and roll.
The RS Ultra is made of hardened chrome with various diameter piston rod which results in superior strenght. 

This in turn, maximises performance under extreme conditions. 

The RS Ultra is micro smooth in its function and with its hardened chrome piston rods, it provides longer seal life thus its reliability surpass expectations. 

Its sintered iron pistons and guide rods, further extends its durability.

Its self sealed packing keeps oil in and contaminants out while its seamless cyclinders and eye rings eliminate weak points and seams failures thus ensuring durability, reliability and optimum performance.


FEATURES AND BENEFITS

  1. 1. HARD CHROMED PISTON ROD REDUCES FRICTION
  2. 2. MULTI LIP OIL SEAL ENSURE LONGER LIFE SPAN
  3. 3. SINTERED IRON ROD GUIDE MADE TO LAST LONGER
  4. 4. 3-STAGE REBOUND VALVING UNIT TO GIVE BETTER CONTROL
  5. 5. SINTERED IRON PISTON FOR DURABILITY
  6. 6. 3-STAGE COMPRESSION VALVING UNIT FOR SMOOTHER ACTION THUS REDUCING FRICTION
  7. 7. SEAMLESS EYE RING FOR PROTECTION AGAINST BREAKAGE
  8. 8. HIGH GRADE FLUID TO SUIT ALL WEATHER CONDITION
  9. 9. AIR


避震器(Shock Absorber;Damper)的需求是由于弹簧不能马上稳定下来,也就是说弹簧被压缩再放开以后,它会持续一段时间又伸又缩,所以避震器可以吸收车轮遇到凹凸路面所引起的震动,使乘坐舒适。
避震器它并不是用来支持车身的重量而是用来抑制弹簧吸震后反弹时的震荡和吸收路面冲击的能量。假如你开过避震器坏掉的车,你就可以体会车子通过每一坑洞、起伏后余波荡漾的弹跳,而避震器正是用来抑制这样的弹跳。没有避震器将无法控制弹簧的反弹,车子遇到崎岖路面时将会产生严重的弹跳,过弯时也会因为弹簧上下的震动而造成轮胎抓地力和循迹性的丧失。 ——百度百科
最直接影响一辆车的舒适性就是悬吊系统,那作为悬吊系统的重要部件之一,避震器(Shock Absorber)可是重要的一份子,主要用抑制弹簧吸震后反弹时的震荡,不同的设计都会影响操控表现和舒适性,车辆的承受性均取决于避震器的软硬度,避震器是由升和降2个动作形成,而避震器的活塞阀片数量和厚度将会影响避震器软硬度。
德系车向来的阀片数量都比较多,所以阻尼力也比较强,滤振表现也比较出色,借此就会觉得非常舒适,而日系车避震器则比较轻巧,轻量化的结构成为它的优势。
当你驾过凹凸不平的路段,避震器就会做出升降的动作,如果少了避震器的运作,这辆车就会墩到妈妈都不认得了,至于其中的避震器调校就必须视乎厂商的功力到哪里。打个比喻德系大厂ZF旗下的SACHS在滤振表现相当出色,能提供舒适豪华的感觉,但是相对耐用性就相对减少,所以没有最好只有适合或不适合。
其实避震器并不属于易损物件,但基于大马的路况不佳造成,车辆行驶时避震器一直在升降运作,造成避震器内部的温度逐渐提升,长期下来就会提早让避震器收工,一般上60,000km就需要替换一组避震器,以提供最佳的舒适度和操控表现。——AUTOMACHI  by Ray Chan

What is LSD?

A limited-slip differential, or LSD, helps get your car's power on the road.

The cool thing about an LSD is that while is allows some freedom between the drive wheels, it also limits the power being sent to just one wheel, mitigating wheel spin and allowing for more traction.

Normal differentials allow a vehicle's engine output to escape through the inside wheel under hard cornering, meaning the inside wheel spins while outside wheel receives little torque.

A limited-slip diff restricts the difference in the wheels' rotational speeds, thus feeding the inside wheel less and the outside wheel more. This in turn improves traction on the way out of the bend, meaning you can drive the car faster.


LSD = 限滑差速器

顾名思义, 一种限制打滑的差速器。

Oil Change Frequently asked Questions


Is it necessary to use a stabilizer or additive with every oil change?
No. Today's engine oils are formulated to fully protect the engine. 

When should I change my oil?
These intervals are based on mileage or time. You should change your oil and filter at or before the end of the oil-change intervals provided by your vehicle's manufacturer. By doing this, you can help keep your engine oil in good condition and provide the best protection for all your components.
