Product Details
***S&D NOTE: test fit control arm bushing, Light scratches- Sold As Is - See photos prior to ordering (What is photo'd is what is included) - ALL SALES FINAL***
034Motorsport's complete Density Line Control Arm Kit with Upper Adjustable or Non-Adjustable Control Arms are designed to be performance replacements for all eight of the factory front upper and lower control arms. The result is tighter handling and more precise steering response than even brand new factory control arms can offer. In addition, adjustable upper control arms allow optimal alignment for your lowered or track driven vehicle.
The factory front control arms are an integral part of the suspension, but can start wearing out as early as 40,000 miles - even on vehicles that see mainly highway commuting miles, trips to the local mall, and school drop-off/pick-up. As the rubber bushings degrade and ball joints develop play, alignment is compromised, and steering becomes less precise. This kit is a drop-in replacement with feature improvements over stock, that will tighten up front-end feel and allow camber adjustment to significantly improve handling.
Density Line Non-Adjustable Control Arms:
034Motorsport's complete Density Line Upper Control Arms are designed to be a performance replacement for all four factory front upper control arms. Featuring high-durometer rubber bushings and high-quality ball joints, Density Line Control Arms are engineered to limit unwanted deflection in the suspension, resulting in tighter handling and more precise steering response than even brand-new factory control arms can offer.
Features:
Density Line Non-Adjustable:
- Complete, Drop-In Replacement for Factory Upper Control Arms
- Offers Improved Handling Feel & Steering Precision
- High-Durometer Rubber Bushings (65 - 70 Durometer)
- No Fluid, So Unlike OE Arms, the Bushings Cannot Leak
- Includes New Hardware & Ball Joints

Installation Note:
It is imperative that the suspension be compressed to static ride height before any suspension pivot bushings are tightened, as per the factory installation procedure. If this is not done, the bushings will tear prematurely as the twisting forces on them will be much higher than is intended. 034Motorsport's Limited Warranty on Density Line products does not cover premature failure due to improper installation or use. We highly recommend professional installation for this product.
