6654 Shock Extension Kit

Exactly as advertised, excellent well designed products!

I bought these for 06 GMC Sierra 1500 Crew Cab. The previous owner had did a 4" drop on the rear and I notice the ride was a bit rough going over bumps. I installed these adapter and man kid you not, it really made a difference.

Fit perfect on the truck with no issues, work as they should. Super happy with purchase.

Fit on my 2002 2500hd after I did 3” drop shackled. It noticeably improved the shock absorber function!

pros -nice black painted coating -thick, solid metal -hardware is also high quality. thick and strong. fits perfectly, no fuss. cons -not intended to work with flip kit imho. BUT it does. (if your shocks collapse enough) -not an extension, more of a "kick out" I have no idea why these are called "shock extension kits". they technically do extend the travel but that doesnt help your shock work better. it actually kicks out toward the shock, away from the axle mounting point to correct the angle at which it is working, putting them closer to a stock angle before you went and messed up your truck by lowering it lol. A flip kit kicks the axle back to create a better pinnion angle, well that in turn makes the rear-most shock (driver side) shorter, then adding the "shock extension kit" actually shortens it even more. On my silverado with a 5/8 drop, my driver side shock rides 2 inches smaller than the right side, at 14" and 16", respectively. im wondering if i should forgo the left side shock extension all together. hmm. cant say she is riding bad though. i would still buy again. just sharing the knowledge.
