Leaperkim Lynx-S Progressive Springs

Enhance your suspension performance with these progressive springs, designed exclusively for the shocks on the Leaperkim Lynx-S and Sherman-L SE.
The key difference with these progressive springs is the extra support they provide throughout the stroke, particularly at the bottom. By utilizing a much higher spring rate at the bottom of the spring, they offer significantly better support and bottom-out resistance when the suspension is fully compressed.
Free Upgrade Program
As part of our commitment to the rider experience, Next Gen Mobility is personally sponsoring this upgrade. We are providing one set of progressive springs at our own expense to customers who purchased a Lynx-S, Sherman-L SE, or standalone Lynx-S shocks with linear springs preinstalled.
-Eligibility: One free set per qualifying previous purchase.
-Verification: all orders will be verified against your purchase history prior to shipping. You are not required to choose the same spring rate as your original purchase—if you feel the need for a free do-over with a different spring, now is your chance!
-How to Get It: Enter the code PRIORPURCHASE at checkout.
Spring Weight Guide
Select your spring rate based on your body weight (measured without safety gear):
-66 lbs: Recommended for riders 170 lbs and under.
-70 lbs: Recommended for riders between 160 lbs – 200 lbs.
-74 lbs: Recommended for riders 185 lbs and up.
Choosing the Right Fit: If you find yourself between two weight categories, use your riding style as the tiebreaker:
-Trail Riders: We recommend opting for the heavier spring weight for better support on technical terrain to minimize bottom-outs.
-Street Riders: We recommend the softer option for a smoother, more plush ride on pavement.
