Improper pinion angle can lead to driveline vibration and premature u-joint & cv-joint failure. Not all 3 1/2 lifts will require a pinion adjustment but going up to 5 1/2 will result in a driveline angle that will need corrected. These 2 1/2" wide steel shims bolt on to the bottom of your leaf packs with longer center pins included. To determine the proper amount we recommend taking measurements before and after installing your suspension lift. The optimum angle is 2. For more measuring info, please call.

MS2020 8" Shock by James Duff Inc.
MS2020 8" Travel Shock - James Duff Midnight Series by Eibach
Our Price: $119.95

Looking for a more sophisticated shock? Want it to match your Bronco in performance and style? Well, you're in luck. New for 2020 our Midnight Series (MS2020) Shocks built by Eibach in the USA! A shock developed by the industry leaders of Bronco suspension takes you beyond a simple hydraulic shock absorber. the new MS2020 delivers the high performance of a high-pressure monotube gas shock in an affordable package. No need for expensive remote reservoirs, the MS2020 provides a nice comfortable ride on the street while providing the extra dampening needed when the going gets TUFF.

This is our 8" travel version, please see below for our other lengths and links to purchase. Estimated ship date is early November.

James Duff's MS2020 is the first and only premium shock specifically designed for Bronco's coil spring suspension. It features a 14mm chrome-hardened piston shaft for superior rigidity and minimal seal wear. The shaft itself is coated with a unique black chromate that is actually more durable then chrome, while offering better resistance to rust than other shocks. The machined aluminum rod end offers strength and good looks and houses American-made polyurethane bushings. The shock body itself is constructed of 2 diameter seamless DOM tubing for excellent heat transfer, and the outside of the shock has a durable Midnight Black Metallic powder-coated finish. Inside, the massive 1-3/4" diameter piston has progressive valving that is tuned to provide a smooth ride on the road but has the ability to quickly step up the dampening and effectively smooth out the bumps off-road. Combining race technology with advanced manufacturing techniques, MS2020 shock absorbers are an unbeatable value, especially when considering that most other shock absorbers on the market are made overseas with inferior materials. MS2020 shocks are Made in the USA and Trail Tested Duff Tuff!
