The Ultimate Bilstein 6112 Struts and Springs Guide

Bilstein 6112 Release, Applications, and Overview

Bilstein has delivered their answer to Rancho's Quicklift Leveling system and Fox's 2.0 Performance Coilovers, albeit without being fully assembled. Bilstein's new 6112 kit features brand new coil springs, a massive 60mm digressive piston, and an adjustable spring seat for 7 different height settings. 7 settings is an upgrade over 5 settings on the 5100 series, which gives more refinement on your vehicle's ride height to be more precise with varying front-end loads. The thickness of the new shock (approx 2.65") allows for far more hydraulic fluid capacity over the 5100, Fox 2.0, and any of Rancho's products. This means greater fluid cooling than most OE-type shocks on the market, along with greater predictability and consistency through varying terrain.

Why leveling struts are better than strut spacers.

When using a steel or aluminum 'puck' as a strut spacer on top of the factory strut mount, this does a couple things to the suspension. It does not preload the coil spring, but rather it drops the entire strut tower down by the leveling amount, in relation to the upper control arm. This decreases droop travel (wheel bottoming out) because the strut tower is placed in a premature dropped position, with limited clearance from the upper control arm.

A leveling strut will use the factory coil springs, and will preload the coil springs, increasing the spring rate, and lifting the vehicle. By preloading the coil spring, this will make the ride slightly firmer, but will also allow for full travel out of the strut tower compared to the strut spacers.

PRE-ASSEMBLY Service Now Available through Shock Surplus

Shock Surplus now offers assembly on all 6112 part numbers, allowing the strut and springs to be installed directly out of the box. New top plates are installed to create a single assembled unit, which can bolt directly into the OEM mounting location. This can save our customers the headache of renting and using a coil spring compressor, or allowing the DIY'r to get the job done themselves without the requirement of more tools. All 6112 listings have assembly as an option on the product page.
