We recommend buying Heavy Duty Progressive Suspension 412 as they give more comfort level and make the riding experience smooth.

Q7.What Is Meant By Progressive Suspension?

Progressive suspension means the smaller number being at the end, will cause the shock to move higher for a given amount of wheel travel causing it to ramp up. Rising rates are also considered progressive.

Q8.How Long Do Motorcycle Shocks Last?

Motorcycle shocks last for up to 5 years.

Q9.Do Progressive MTB Springs Work?

The MTB spring works as advertised. It smooths or removes bottom outs pretty well. I am on a fairly linear bike to start, and while keeping the coil feel pretty as the same. The Small bump compliance, looks pretty similar to the stock spring.

Q10.What Is The Difference Between Standard And Heavy-Duty Progressive Shocks?

If the rider is less than 250 lbs, then use the standard duty shocks. If the rider is above 250 lbs. (regardless if you ride two up or not), use the heavy-duty shock.

Yes, progressive springs ride better and also make the suspension stiffer rapidly.

Q12.What’re Better Linear Or Progressive Springs?

Progressive rate springs have mostly less total deflection compared to a linear rate spring of the same free length. So, progressive springs are better than linear springs.

Q13.Why Are Heavy Duty Coil Springs Used?

Heavy duty coil springs are used to absorb some amount of weight to carry for a truck. It will increase its capacity load and prevent sagging.


Please keep these points in mind before purchasing Progressive 412 series shocks:

  • These shocks are measured in a way that the centre-of-eyelet is to the center-of-eyelet.
  • If a Shock is slightly longer then we advise that the stock may be altered to the head angle slightly and this may provide approximate quicker steering.
  • In case the shocks are slightly shorter then we advise that the stock may be altered to the head angle slightly and this may provide approximate slower steering.
  • Before purchasing the shock or attempting to install the shocks that are different than the OEM length, confirm that your wheel travel can be altered without causing issues like clearance, such as swingarm/axle to exhaust contact as well as chain/belt guard or tire contact.
