EPI warrants its products to be free of defects in material and manufacturing for 1 year from the original date of purchase. This does not apply to electrical components, non-EPI branded parts, OEM primary and secondary clutches, normal wear or conditions resulting from misuse, abuse, negligence, accident, improper application, improper installation or alteration. This warranty covers the repair or replacement of the EPI product in question only, and does not cover labor charges to remove or install the EPI part or any other part or component that may incur damage as a result of a defective EPI part. The customer is responsible for any labor charges involved in removing and replacing the defective part, and for shipping charges to return the defective part to EPI.

BELTS: If, within 1 year of original PURCHASE date, the EPI belt fails due to a defect in material or manufacturing, a replacement belt will be provided by EPI upon inspection. A $20 handling fee and certain conditions apply, please see your EPI belt sleeve warranty form or contact our Returns Department at 218-829-6036 for details, and request a warranty claim card.

Value Line Clutches: Due to the primary clutch being a normal wear item and the extreme conditions it operates in, we offer a limited 30 day warranty on manufacturing defects only. If you experience any failure of this clutch within 30 days that is not due to normal wear and use, we will inspect and replace the clutch if we determine it was due to a manufacturing defect.

  1. Great Replacement for Stock Springs 5 Star Review

    Posted by on 4th Aug 2021

    My stock springs were tired. I started hauling a meat wagon trailer and it was just too much for the old springs. These were a fairly simple install with a spring compressor tool. Ride is a slightly stiffer, but not harsh. I can haul a lot more weight while maintaining good ground clearance now.

    Previously installed EPI front springs to hold my snow plow. Overall I'm very happy with improved capabilities of my ATV.

  2. Shock springs 5 Star Review

    Posted by on 21st Aug 2020

    Way stiffer than the OEM springs. Great product! Solved all the sagging on the rear end of my 2010 sportsman 800.


  3. Improved handling of weight but holds shock too far 4 Star Review

    Posted by on 12th Apr 2019

    I installed these springs on the rear of my 07 Sportsman 800 after installing EPI HD springs on the front. They definitely helped with handling, especially when I have extra weight on the back. The only complaint I have about these are that the springs holds the shocks fully extended, barely compressing when I get on the ATV, which in turn doesn't allow for hardly any rebound and slaps the shock against the internal stop more then it should.


  4. Sportsman 800 Front and rear springs. 4 Star Review

    Posted by on 28th Feb 2015

    While riding the Hatfield/McCoy trails my 06 Sportsman began nose diving into corners. At first I thought it was just me getting old and not being able to handle my bike anymore. After installing front and rear springs my 800 is better then ever. Making me ride like a 16 year old again. A must do upgrade for any Polaris.
