The most accurate method for shock measurement:
- Measure the eye to eye length.
- Attach a shock pump and slowly remove all the air from the shock.
- Compress the shock fully and measure the eye to eye length again.
- Subtract this measurement from the initial eye to eye length to find the usable stroke. (ie. 185 – 132.5 = 52.5)
Are bigger shocks better?
The larger the passage, the less resistance to motion the shock will give, and the smaller the hole, the tighter. A shock absorber must be “tuned” to match the vehicle it’s attached to in order to work properly.
How do you pick the right size shocks?
Take careful note of which component of the suspension is limiting the suspension from traveling further. Raise the tire enough to prevent that suspension component from binding. Measure between the center of the upper and lower shock mounting points. This gives you the desired maximum length shock.
What is the best shock angle?
30 degrees is the absolute maximum and 5 degrees being ideal.
How do you measure the stroke length of a rear shock?
Stroke length refers to the total distance the shock can compress. You can measure the stroke length by subtracting the eye to eye length when the shock is fully compressed, from the eye to eye length when the shock is fully extended – you should get relatively close to the shock’s stroke length.
What happens if shocks are too short?
If the extended length of the shock absorber is too short it will “top-out” and reduce the extended travel. “Topping out” is the term used when the piston inside the shock absorber collides with the cylinder head.
Which shocks give the smoothest ride?
The smoothest riding shocks you can get would be ones identical or nearly identical to factory tuning, typically something like the Bilstein B4 series, KYB Excel-G Series, or Monroe OE Spectrum. All of these have the most forgiving valving for road handling and comfort.
Will changing shocks improve ride?
The customer may think that new shocks and struts will simply make their ride smoother, but the truth is that new shocks and struts can do a whole lot more. New shocks and struts can make a vehicle corner and brake like when it was new.
Are aftermarket shocks worth it?
Shock absorbers: Aftermarket shocks can offer improved handling at high speed or (particularly for trucks and SUVs) when driving in very rocky or bumpy conditions. Some aftermarket shocks are even adjustable, so the owner can fine tune the ride to his or her liking.
How do I know what size rear shock I need?
The eye-to-eye measurement is the length of the shock from the centre of one mounting eye to the centre of the other. Also remember to measure the size of the connecting hardware, including the width of the end bushings and the size of the bolts used to attach shock to frame (normally 5mm or 7mm).
Are shocks universal?
Shocks aren’t universal in length or fitment. Lifted trucks have longer shocks than factory height trucks. This isn’t such an issue figuring out strut or shock lengths on passenger car vehicles, 99% of the time its going to be factory length parts.
What do off road shocks do?
Technically speaking, shocks convert kinetic energy into thermal energy. Shock absorber are also referred to as “dampers” because they dampen the energy of the spring. By creating resistance to up and down motion, the dampers turn motion energy into heat, and then dissipate the heat to the atmosphere.
What angle should rear shocks be?
Most people aim for 90 degrees at full bump. That is from the front leaf spring pivot, to the lower shock pivot, and then to the upper shock pivot. This creates a slight rising rate. That being said there are lots of trucks people just mount the shocks where “they look good”.
Can you install shocks wrong?
The wrong height for the spring plate can result in the spring having no pre-tension. On systems with a side load spring the spring can become stuck or fall out. The shock absorber goes into the compression stop, has higher wear on the buffer and does not allow sufficient bump travel.
Can you install rear shocks upside down?
Ultimately: don’t mount shocks upside down just because it looks cool. Sometimes a shock must be mounted upside down due to space limitations, or to protect the shock body, if this is the case, make sure you use a shock designed to be mounted upside down.
How much travel does my rear shock have?
the rear wheel travels 5.5inches. the shock travels 1.25 inches (called stroke). a bike’s travel is measured by how much the wheel moves, not the amount the shock moves.
What is MTB shock stroke?
Shock stroke is a measurement of how far the shock shaft enters the shock body between full extension and full compression. Trunion refers to a compact shock mounting configuration that shortens the shock’s overall length by placing the mounts on the shock body itself.
What is the stroke on a rear shock?
^Stroke (or stroke length) refers to the distance the shock compresses under load. A lever ratio is often stated for a shock and represents rear wheel compression: shock compression (stroke) for a given length. For example, if the ratio is 2:1, then for every 1mm in shock compression, the rear wheel compression is 2mm.
Can shocks be too long?
Your compressed shock should not be longer than that measurement. You do not want your shocks to bottom out b4 the bump stop hits the axle. You could try to get different shocks or move your bump stops to correct.
Does shock absorber affect height?
Bad shocks affect ride and handling, but they won’t change the ride height of the car.
What causes shocks to bottom out?
Bottoming out can result from a compressed spring and can result in damage to your undercarriage. Often, the first sign of a suspension issue is a change in the quality of your vehicle’s ride. You may immediately notice bumpiness and jostling when you drive, even when you’re navigating a fairly even and level road.
Which is better gas or oil filled shocks?
1 Answers: Generally, gas filled shock absorber are considered better and more advance than oil filled shock absorber, they allow better performance, comfort and driving safety.
What makes Bilstein shocks so good?
Bilstein’s technically superior, patented monotube gas charged design allows the excessive heat from the oil to transfer to the outer surface of the shock body and dissipate more efficiently. The dividing piston also permits the oil to expand as heat builds, preventing aeration (foaming) and viscosity loss.
How long do shocks last?
On average, if your car has been “babied,” you can expect your shocks/struts to last about 10 years. If you have really used your car like a workhorse, 5 years is probably all you can expect. This means that for the average driver, 7 or 8 years is the maximum life expectancy of most shocks and struts.
Can you change shocks without a jack?
You can definitely do it.
How do I make my car ride smoother?
Here are 4 ways you can improve the ride quality of your car:
- Avoid bigger wheels if you want a smoother ride. As a general rule, bigger wheels result in a rougher ride.
- Choose the right tires. Not all tires are created equal.
- Change your suspension parts.
- Make sure your car is the right height.
How do I know if my shocks are bad?
The Warning Signs Of Worn Shocks And Struts
- Instability at highway speeds.
- Vehicle “tips” to one side in turns.
- The front end dives more than expected during hard braking.
- Rear-end squat during acceleration.
- Tires bouncing excessively.
- Unusual tire wear.
- Leaking fluid on the exterior of shocks or struts.
Are aftermarket shocks better than OEM?
OEM shocks and struts perform perfectly for nearly all types of driving, last a long time, and perform better than aftermarket shocks in all but the most extreme situations.
Are aftermarket shocks better than stock?
The answer is easy. OEM shocks offer so much more value than aftermarket shocks do. In fact, aftermarket shocks are almost always a bad investment. This comparison guide explains why OEM shocks are better than aftermarket shocks.
Are cheap shocks OK?
A cheap shock will let everything on your vehicle rattle more than a good damper that controls the flow of energy through your rig. This superior behavior translates into less maintenance cost for the life of your vehicle.
