Shock Therapy Dual Rate Spring Kit (DRS) 2016-18 Polaris XP4 Turbo Fox Bypass Shocks (4 Seat)



Level 4 spring kit. The ultimate in suspension improvement through the springs.  This kit includes everything you need to install a true dual rate spring kit on your 2018 XP4T. With the much lighter upper springs you get an incredibly plush ride over the stock springs. Small chop and whoops become much smoother. Bucking and kicking in the rear is limited as well. The LOWER springs we supply are a heavier rate than the factory springs which helps you even more by eliminating bottoming, body roll and front dive. They allow you to run the cross over rings higher on the shock which lets you feel the softer combined spring rate longer for a more plush ride. Since the lower springs only come into play in the biggest hits you can run harder and faster than you ever could have before without bottoming out but at the same time retaining that nice plush ride at normal speeds. This kit is highly recommended to be run in conjunction with Shock Therapy internal valving. This way the added spring rates when fully compressed can be matched with more rebound control for the perfect performance in the roughest situations.  This is the ultimate in smooth ride while still sacrificing nothing in the big hits. This kit includes 3.55″ diameter rear springs which are considerably more costly than a 3″ spring. Put in the notes on when you check out what accessories you have on the car and the type of driving you do and we will tailor the spring kit for you.

Level 4 spring……………………..……………$1,149.50

All of our proprietary springs are made in the USA from the highest quality CrSi materials. This means they are always the exact rate we want and don’t fade or break. They cost more when made from this material but are absolutely worth it when it comes to function and longevity.
