Be confident in your purchase, we are an Authorized Lightech Dealer. How awesome is that?! Our chain adjusters are obtained from A solid piece, CNC machined from billet Aluminium 7075-T6 and 6082 alloys, anodized with stainless steel fittings. The precise machining allows precise adjustment first time every time. To adjust simply turn the small adjuster by hand, which has small detents that click when turned, and a metric scale is stamped into the alloy so you can achieve 100% accurate line up of left right sides. Featuring a sleek race design and available in black, red, blue and gold, our chain adjusters are perfect for both track and street. Don't forget the chain adjuster lifters (as option) which allows you to use spool-type rear stands for a more secure lift. Each kit includes: 2 x chain adjusters ready assembled, fitting instructions, all necessary fittings for each model.
